The Most Common Four LED Screen Assembly Method

LED display screen assembly is a complex and tedious process, and each link requires engineering and technical personnel have excellent professional skills, to be able make LED display products do precisely and fine. Insiders know that the LED display is composed of many modules which are spliced, and the module is assembled by many beads. In the LED display assembly process, assembly steps ring after ring, ring must be careful, otherwise it will affect the LED display effect. In order to meet the requirements of large area, high brightness and dynamic display screen of LED display, as well as matching drive requirements of LED driver. The following describes the four types of LED display connection form:

1, the whole screen of LED display screen series: general assembly simple series connection in LED1-n, end to end, is equal to the current through LED display work. The other is an improved method of 1.1 with series connection with bypass.

2, LED screen whole screen parallel assembly method: one is simple parallel form, and the other is independent matching parallel form. The LED1-n in a simple shunt is parallel to each other, and the voltage on each LED is equal when operating. The reliability is not high, but also for the issue of parallel form, independent, with good effect, single LED display driver to protect the integrity, failure does not affect other work, can be matched with different characteristics.

3, LED display cross array assembly mode: cross array shape, mainly in order to improve the reliability of LED display work, reduce the failure rate raised.
4, LED display mixed assembly method: appeal by parallel and series of advantages put forward by each other. Also includes 2 kinds. One is the combination of the first and the subsequent, and the other is the combination of the first and the subsequent.
The above four type LED display, assembly, connection, each has its advantages and disadvantages, according to different applications, choose the most suitable LED display connection. Many engineering people tend to ignore this, leading to a variety of connection faults in the LED display, which ultimately affect product quality and reduce user confidence. Thus, the assembly of the LED display, details determine success or failure!

LED Display Working Principle

A LED display is composed of a number of modular display units (led display panels or unit display boxes), plus a set of appropriate controllers (master panel or control system). Therefore, a variety of display boards (or unit box) with different control technology controller, can form many kinds of LED display, in order to meet the needs of different environments, different display requirements.
LED display structure (with more complex synchronous full color for example)

1, The metal structure frame, its function is to constitute the inner frame, carrying display, unit boards or modules and other circuit boards and switching power supply

2. Display unit: it is the main part of LED display. It is composed of LED lamp and drive circuit. The user is a variety of inner unit display panels, outdoor screen is a module box.

3 、Scanning control board: the function of the circuit board is data buffer, producing various scanning signals and the duty cycle gray level control signal.

4, Switching power supply: 220V alternating current into a variety of DC power supply, providing a variety of circuits.

5 、 Transmission cable: the display data and control signals produced by the main controller are transmitted to the screen by twisted pair cables.

6 、Master controller: the input of RGB digital video signal buffer, gray level transformation, re organization, and produce a variety of control signals.

7 、Special display card and multimedia card: besides the basic function of computer display card, it also outputs digital RGB signal and line, field and blanking signal to master controller. In addition to the above functions, multimedia can also convert analog Video signals into digital RGB signals (video acquisition).

The main working principle of LED display

LED display usually consists of main controller, scanning board, display control unit and LED display, the main controller card to obtain the color brightness data of each pixel from the computer display screen, and then allocated to the plurality of scanning board, each scan board is responsible for the control of the LED display to the row (column), and each line (column) on the LED display signal through the various display control unit by serial cascade transmission mode, each display control unit for LED display. The main job of the main controller is to convert the computer display signal into the data needed by the LED display and the control signal format. The function of the display control single carrier is similar to that of an image display screen, and is generally composed of a shift register latch with a gray level control function. But video LED displays are often larger, so integrated circuits with larger integration sizes should be used. Scanning pull the role of the so-called nexus, the video signal on the one hand it to accept the main controller, on the other hand to the data to their respective display control unit, and the scanning transmission does not belong to the pull down a cascade of data. Video signals and LED display data, in space, time, order and other aspects of the difference, need to have a scan board to coordinate.

Factors to Consider When Choosing LED Display

On the purchase of LED display, many customers do not know how to buy cost-effective products, there are many users on the Internet to collect information about this aspect, but always failed to get a satisfactory answer. What are the factors that should be considered when buying a display?

The first point: You need to know the length and width ratio of the general screen

1, graphic screen: according to the content of the show;

2, video screen: generally 4:3 or close to 4:3; ideal ratio is 16:9.

Second: What are the factors that should be taken into account in the size design of the screen?

1, display the content of the need;

2, site space conditions;

3, display unit, template size (indoor screen) or pixel size (Hu Waiping).

Third: You need to know the points that the control system can control

Communication screen A card: monochrome, two-color 1024 * 64

Communication screen B card: monochrome: 896 * 512 double color: 896 * 256

DVI dual color screen: 1280 * 768

DVI full color: 1024 * 512

Fourth: Need to understand the display power consumption indicators and power requirements?

The power consumption of the display screen is divided into average power consumption and maximum power consumption. The average power consumption is also called work capacity, which is the actual power consumption at ordinary times. The maximum power consumption is the power consumption in the extreme situations such as starting or full lighting, and the maximum power consumption is an essential factor for AC power supply (wire diameter, switch, etc.). The average power consumption is usually 1/3 of the maximum power consumption. The display screen is a large precision electronic equipment. In order to work safely and reliably, the AC220V power input or the AC220V input terminal of the computer connected to it must be grounded.

The fifth point: The need to understand what a full color patch and indoor full color module?

The 1 part: full color luminous module, display module is generally yellow green, pure green module price is more expensive; SMD full color commonly used pure green tube core;

2, the display module: full color pixel visual feeling is thick, low brightness, easy to have the mosaic phenomenon; SMD full color consistency, high brightness;

3, full-color module maintenance: maintenance is not easy, the whole module replacement cost is high; and the whole patch to maintain, and can be a single lamp replacement;

The sixth point: Why is the production cycle of outdoor screen longer?

1, raw materials procurement: LED lamp purchasing cycle is longer, especially imported core, the order cycle needs 4 – 6 weeks;

2, the production process is complex: need to pass PCB design, shell production, filling glue, white balance, etc.;

3, the structure requirements are strict: generally for box design, need to consider wind, rain, lightning protection, etc..

The seventh point: What factors need to consider the allowable size of the screen area?

1. The relation between effective sight distance and actual site size;

2, pixel size and resolution;

3, the element is the area estimation of the cardinal number;

4, the screen body mechanical installation and maintenance of operating space;

5, the influence of screen tilt angle on distance;

The eighth point: You need to know the brightness of the environment, what are the brightness requirements for the screen?

General brightness requirements are as follows:

1, indoor: >800CD/M2

2 and semi indoor: >2000CD/M2

3, outdoor (North): >4000CD/M2

4, outdoor (South): >8000CD/M2

How do we calculate the brightness of LED lights in the light of the requirements of the brightness and the point density?

The calculation method is as follows: (take two red, one green and one blue as an example)

Red LED lamp brightness: brightness (CD) /M2 / /M2 x 0.3 / 2 points

Green LED lamp brightness: brightness (CD) /M2 / /M2 * 0.6 points

Blue LED lamp brightness: brightness (CD) /M2 / /M2 * 0.1 points

For example: 2500 points per square meter density, 2R1G1B, per square meter brightness requirement is 5000CD/M2, then:

Red LED lamp brightness is: 5000 / 2500 x 0.3 / 2=0.3

Green LED lamp brightness is: 5000 / 2500 x 0.6=1.2

Blue LED lamp brightness is: 5000 / 2500 x 0.1=0.2

The brightness of each pixel is 0.3 * 2+1.2+0.2=2.0CD

The ninth point: What kind of effect should be considered?

1, text display: depending on the size of the text and resolution requirements;

2, ordinary video display: 320 * 240 dot matrix;

3, the standard of digital DVD display: 640 * 480 dot matrix;

4, complete computer video: 800 * 600 dot matrix;

Tenth: Need to know the design and installation of outdoor display?

1, the screen body and the construction of the joint must be strictly waterproof, leak proof; screen body should have good drainage measures, once the water can discharge smoothly;

2. Install lightning protection devices on display screens and buildings. The main body of the display screen is well grounded and the grounding resistance is less than 3 ohms, so that the high current caused by lightning is released in time;

3, install ventilation equipment to cool down, so that the temperature inside the screen is between -10 and 40 degrees centigrade. An axial fan is installed behind the screen to discharge heat;

4. Select industrial integrated circuit chips with working temperature between -40 and 80 degrees centigrade to prevent the winter temperature from too low and make the display screen unable to start. ;

5, in order to ensure a strong light in the environment of long-distance vision, you must choose ultra high brightness led;

6, display media selection of new wide view tube, wide viewing angle, pure color, consistent coordination, life expectancy of more than 100 thousand hours. Display package media is currently the most popular cover band along the square cylinder, silica gel seal, with no metal assembly; the appearance of fine appearance, durable, anti sunlight, dustproof, waterproof, anti high temperature, anti short circuit five prevention “.

Buying LED Displays Is A High Return Value Investment

Statistics show that companies that make use of LED display as part of their marketing and communication strategy grow on average year after year and can point their growth back to messaging that was relevant.
W5 (5)
Most people who talk about LED display Solutions for advertising within a business or organization usually ask the question:

Why Buying LED Displays Is A High Return Value Investment

For instance, HD television is considered a purchase, but since it brings entertainment value to the family, it can be regarded as a family investment.

One important aspect in purchasing a LED display is to understand how the benefits and its importance to the organization out-weigh the costs involved.

LED display Cost

LED display is not a one-time purchase, as there are costs involved beyond the initial cost. There are also ongoing and recurring costs. The cost of purchasing and having a digital sign includes:

Hardware and software
Connectivity and installation
Software upgrades

LED display is an investment where you don’t have to settle for a cheaper solution for your business.

True Cost of a LED display

The initial cost only makes up a small part of a greater picture with which the overall value it brings benefits the organization. When purchasing a LED display system, look beyond the cost. Realize the real value that it will bring to your business or organization.

Why is LED display an investment?

It adds value to the place and attracts customers.
It helps market and promote the business.
It enhances conversion and generates business leads.
It gives better brand image and recognition
It improves product and brand loyalty
It helps to better educate customers

It is apt to say that the cost of a digital sign is a significant business investment but the profitable possibilities are endless. With so much value that a digital sign brings, it cannot simply be termed as a mere business purchase. It is an investment that pays off in the long-run.

The U.S. Small Business Administration reveals that “For businesses that choose to enhance their signage with an electronic message display, the owners typically see an increase in business of 15% to 150%.”

When discussing LED display technology with your customers, make them see that aside from being an excellent advertising and customer service tool, it is also a revenue generating tool when used effectively. Justify the expense involved in purchasing a LED display system. Your customers should feel confident that the digital sign will deliver both financial and non-financial returns.

Investing in a LED display is a key element of business success. It is a permanent asset whereas other forms of advertising are a repeated expense.

It is clear that LED display is not an expense, it’s an investment. It gives a long-term, high return on investment value.

Improve Your Business ROI Benefits of LED Screen Advertising

LED display has revolutionized the advertising market and has grown in popularity especially among business owners. This powerful advertising tool is not only more affordable these days, but is also much easier to implement and manage. Compared to other signage or advertising solutions, digital signs offer dynamic and high-definition messaging, unmatched by other advertising mediums like television, radio and newspapers.

They provide countless benefits and are considered a significant investment for any business. Businesses can respond to market changes in an instant by simply changing their LED display message.
A good LED display partner is not only focused on making a sale, but more importantly, they share the real power of LED screen to their clients. They make their clients see that a digital LED screen is a significant business investment.  They help customers recognize how advertising and marketing works through this investment.

One of the major benefits of LED screen advertising is geographic proximity and the way it generates business leads. Many business owners say that new customers come into their store once they see their electronic display. It gives businesses the opportunity to communicate with potential customers who are on the road, at their front doors or those just passing by.

LED display has also been favored over other advertising mediums because of its flexibility in managing content. It also requires less manpower and resources to deploy.

LED screen partners should be able to discuss relevant facts with their clients. This includes projected revenues, expenses involved, net sales, benchmarking scenarios and reviewing current sales. It is also essential to discuss the unique challenges that affect led display return on investment (ROI), standard solution elements, best practices and some case studies that assist ROI conversations.

Measuring LED display ROI

LED display has proven itself to provide the highest marketing ROI. It is the most cost effective advertising solution for your business since it has the lowest cost per 1000 exposures or CPM. Its CPM is about $0.15 compared to other advertising mediums (like newspaper) with over $5 CPM. This low CPM means that a LED display can reach a broader audience for less money.

ROI is one of the most important calculations a business has to measure. The ROI of LED display is long-term. The ability to measure ROI is a critical aspect of marketing that helps determine the impact and value of the new business investment solution.

Factors in determining ROI

Projected Revenue: This depends on several factors such as people passing or driving by your business each day and the number of impressions it makes.

Expenses Involved: When calculating ROI of LED display, consider these expenses- Total cost of buying and installing the LED display, electrical expenses for running the display and maintenance and labor costs.

Net Sales and Profits: After a month or two, calculate the net sales and profits. Compare the results with the previous revenue before implementing LED screen. You will begin to see the payoff of your investment.

With the latest technologies, businesses today have access to every tool, guides and tips to track all aspects of their LED display.

Without a doubt, customers who make proper use of electronic LED display for their business will surely reap the benefits. According to the SBA, the US Small Business Administration, LED displays typically bring an increase in business of at least 15%.

In Conclusion

From an increase in foot traffic to a dramatic increase in sales and greater recognition in their community, LED display proves to be a smart advertising tool. The ROI from this investment allows businesses to reach their goals, expand their business and grow their companies.

Analysis of Quality Problems of LED Display Devices in Production Process

The production and installation technology of LED display screen has a great influence on the quality of display. From the choice of production materials to processing to finished products, each link needs to be strictly checked and detailed to every step. In addition, in the process of using LED display, LED display should also be regularly checked and maintained. If the quality problems are found, remedial measures should be taken in time.

Today, the scope of LED display applications continue to expand, and the number of LED display components is also increasing, and the quality of LED display components has a great impact on the quality of LED display. However, many of the LED display element is mainly embodied in quality uneven in quality, the following points: one is the new LED display element is still in the trial stage, the quality can not be guaranteed, two is the professional level and comprehensive quality of the LED display element of production personnel is not high, greater mobility, the three is the LED display elements of poor quality of the original, not the LED display the production and use of demand.

1. electrostatic problems analysis

In the process of production and installation of LED display, static electricity has a great influence on the quality of LED display. However, many LED display production and installation enterprises only know

To the importance of electrostatic control in the welding process of LED display screen, there is insufficient understanding of the importance of electrostatic control in other links. In the north, winter cold and dry climate, the electrostatic voltage is very high, will destroy the static LED display circuit, the circuit is damaged, the performance and service life of LED display will be affected in different degrees. Therefore, in the LED display production and installation process, we must pay attention to anti-static control, to avoid damage to the LED display.

2. welding link control problem analysis

There are many quality problems in welding process will LED display, mainly reflected in the following points: one is the electrostatic prevention and control of enterprise management is not in place, the two is the LED display application temperature and air humidity control is not reasonable, the three is the LED display element welding time control is not good, the four is the quality problems of welding materials, five is the welding personnel do not have

Professional welding technology, professional level is low. Many welding enterprises do not have professional welding personnel, the mobility of personnel is relatively large, leading to lack of technical guarantee for welding of LED display screen. LED display in use after a period of time, the brightness of the screen becomes low, the reason for this phenomenon is not reasonable to control the welding welding personnel time and temperature, resulting in LED display memory in fog, thereby affecting the brightness of the screen. Therefore, in order to ensure the quality of LED display and control welding problems properly, welding enterprises must strengthen personnel training, and continuously improve the professional level and overall quality of welding personnel. In addition, welding enterprises can set up rewards mechanism in the welding personnel, and give some material rewards or spiritual rewards to the excellent employees, so as to improve the enthusiasm and enthusiasm of the welding staff.

Aging analysis of LED display screen

Normally, the LED screen should be placed 72 hours before the show, and the 72 hours are LED screen aging time. However, from the actual situation, many LED display manufacturers do not display the aging process, so that we can not find the quality problems of the LED display, nor can we take measures to solve the quality problems. In fact, many quality problems found in the process of the LED display to the LED display, LED display a lot of much maintenance, the main reason is that the LED display no aging treatment on stage before. If we do not deal with the aging of the LED screen, it will not only affect the quality of the LED display, but also increase the maintenance and maintenance costs of the LED display, thereby reducing the economic benefits of the application enterprise.

4. LED screen mask problem analysis

Typically, LED display rooms are LED lights, people will find better visual effect from the appearance of many LED display, but from the side the visual effect is not very ideal, have varying degrees of mosaic phenomenon, affecting the brightness of the LED display panel, the cause of the problem is the existence of LED display screen mask quality problems. LED display mask role in the following aspects: first, to protect the LED display, two is to enhance the brightness of the LED display, enhance the color of the background, so that LED screen and background contrast. If the LED display mask quality problems or the installation method is not correct, not only to protect the LED display, it will destroy the LED display, affects the performance and service life of LED display screen. LED display screen mask unqualified reflected in the following points: one is the LED display mask material is not good, there are two impurity LED display mask surface, three is the LED display strong reflective mask, four is the LED display mask fixing screw number is relatively small, LED display mask less stable, five is the LED display screen mask and display circuit board cannot combine. Therefore, in order to ensure the quality of LED display, it is necessary to ensure the quality of LED screen mask, reasonable selection, reasonable installation.

5. display module problem analysis

LED display module problems are mainly reflected in the following aspects: first, the module shell quality problems; two, the module material is not good. To ensure the quality of LED display, we also need to ensure the quality of LED display module, select high quality materials, strictly control the use of module glue, to prevent leakage of glue.


Although the scope of application of the LED display screen is constantly expanding, but LED still exist many problems in the application process, the only reasonable solution to these problems, in order to ensure the quality and performance of the LED display, LED display prolong service life, reduce the maintenance cost of LED display. LED display quality problems can be reflected in six aspects, any link is crucial. Therefore, the staff must combine the actual situation, reasonable formulation of LED display quality control program, to ensure the quality of LED display components and masks, pay attention to the LED display factory aging problem. In addition, the staff should also do the anti-static LED display, LED display components will be affected or static, resulting in LED display damage, increase the maintenance and maintenance cost LED display.

Rainy Season Hits! Let The Outdoor LED Screens to Ride Out The Rainy Season

Rainy weather is coming, heavy rain and muggy weather occur again and again. The LED display lamp belongs to MSD components (moisture sensitive devices), wet weather is a big challenge for LED display.
Matters needing attention:

The outdoor LED screen itself is more complex than the indoor environment, not only to consider the wet problems, but also to do waterproof and other rainy days maintenance work, especially in some rainy seasons and regions. Central and southwest regions along the Yangtze River are mostly hot sauna climate, high temperature, humidity, and deformation device; in the Southern China area, the coastal salt fog weather, typhoon, fog and other inclement weather, high temperature and high humidity; East China in May will usher in the rainy season, high temperature, high humidity, low wind speed and illumination are scarce the device, easy to mold.
OFSE391 (6)
Protective measures:

In addition to the LED display production design for waterproof and moisture-proof, we may also encounter screen in the warehouse accidental water conditions. In case the screen is flooded, we can do the following:

1, with the fastest speed with fans or other tools, the water inlet LED screen completely dried.

2, completely dry the screen after the aging of the body, the specific steps are as follows:

A, the brightness (Quan Bai) tune to 10%, electrify aging 8-12 hours.

B, the brightness (Quan Bai) tune to 30%, electrify aging 12 hours.

C, the brightness (Quan Bai) tune to 60%, electrify aging 12-24 hours.

D, the brightness (Quan Bai) tune to 80%, electrify aging 12-24 hours.

E, the brightness (Quan Bai) tune to 100%, electrify aging 8-12 hours.

With the above procedure, the LED screen will be restored to normal, but the following points should also be noted during the process:

1, do not put the LED display screen body into the air box, so that the LED lamp is easily blocked.

2, in the warehouse when the water, the air box may be flooded, should be exposed to all air boxes, to prevent the water in the container after the evaporation to the LED display inside.

3, all influent LED display does not deal with in time, may more or less affect the stability of the screen, in the emergency process, the screen power may occur after the death of the phenomenon of light.

4. All inlet LED display screens are in the air box. More than 72 hours, the screen basically no repair value, please handle with care.

In addition, both indoor and outdoor screen screen, most effective way to avoid the wet damage function is often used to display, the working state of display itself will generate some heat, some water vapor can be evaporated, thus greatly reducing the possibility of short-circuit caused by damp. As a result, the often used display screen has a much smaller impact on the relative humidity of the less common display. Optokingdom engineer suggested that in rainy wet season, LED screen display at least used more than once a week, at least once a month to open the screen, lit more than 2 hours.

Common Causes of LED Display Failure

Nowaday, LED display has become a part of people’s lives, the streets and lanes, the square station, can be seen all kinds of different sizes of different types of LED display. It is a set of optical, structural mechanics, electronics, computer science in a systematic project. According to statistics, ninety of all domestic LED fault screen percent are large or small, if summed up the main attribution of these faults, we can from the fault source control, to improve the display quality.

LED display 80% failure is caused by the following factors: AC power distribution wiring harness, terminal, connector, signal and low voltage DC wiring harness and connector, switch power module, fan, plastic shell components. These interfaces, cables, power, if you do not choose the bottom, will lead to a whole or part of the black screen LED display, flower screen, mosaic, no signal, etc.. These are also very difficult to maintain, so we are in the production process is to pay attention to reduce the failure rate.

The rest of the fault and 80% for the following reasons: PCBA solder joints, capacitors, terminals, LED lamps, Water Leakage dust caused by the level of protection for the lack of the packing box, leakage screw hardware corrosion control board. These reasons will lead to the LED screen with blind lights or highlights, one or more lines are not bright, lack of color, etc., if the control card or software problems will lead to abnormal image display. Outdoor LED display must be strictly in accordance with the testing standards to design, waterproof and dustproof, wind resistant to high temperature, otherwise it is easy to appear all kinds of faults, and even make the entire LED display scrapped. In addition, the operator should grasp the relevant basic knowledge, with good habits, coupled with professional maintenance personnel, but also to a certain extent, reduce the failure rate.
