How to reasonably planning the installation position of large LED screen

Outdoor advertising is a big trend, only active responders can master more initiative. In the big billboard was transformed into LED large screen process, the installation location, screen quality, playback content three factors are indispensable. Which LED display installation location is the direct impact of advertising revenue factors.
1. The system can automatically adjust the brightness adjustment system

We know that day and night, different times and places the brightness of the environment changes greatly, if the large LED screen display brightness greater than 60% of the ambient brightness we obviously feel the eyes do not meet, that is caused by the light pollution to people The Through the outdoor brightness collection system, at any time on the environment brightness collection. Display flat control system through the receiving system data automatically converted by software for the environment broadcast brightness.

2. Multi-level gray correction technology

Ordinary display system uses 8bit color display level, so that in some low gray and color over the color blunt. Will also cause color light does not meet. The new large LED screen control system uses 14bit color display level, greatly improving the color in the excessive hardness. So that people can feel soft when watching. To avoid people’s discomfort to light.

3. The installation of a reasonable choice of location and display area of the reasonable planning

Viewing distance and viewing angle with the display area has an empirical plan, while the image study in the display viewing distance and viewing angle has specific design requirements. In the design of the display should be as much as possible to meet the design requirements, reasonable planning.

Actually, the next few years the domestic LED display large screen market is still in the growth trend, the main growth space will mainly come from the traditional inkjet, neon lights, billboards to replace the market, as well as high-definition, 3D, intelligent, monitoring the market, road traffic Function high-end LED electronic display market. As long as the standard industry order, display manufacturers to enhance the level of research and development, enhance their core competitiveness, product demand to guide the market, will be in the fierce competition in the market to win a place.

Five Key Points To Solve LED Display Black Screen

In use, LED display black screen this fault is very critical. How do we judge the black screen LED display, and how to deal with it? When you read the following five points, you know.

1. Make sure all the hardware, including the control system, is fully powered up. (Note: +5V, do not reverse, wrong)

2, check and repeatedly confirmed that the serial port for connecting the controller is loose or fall off phenomenon. LED display manufacturers suggest: if the black during the loading process, it is likely to be due to the reasons, that is, in the communication process due to loose communication lines and interrupt, so the screen black. Do not think that the display body did not move, the line can not be loose, please check it, which is very important for you to quickly solve the problem. )

3, check and confirm the connection LED display screen and the main control card connected to the HUB distribution board is closely connected, whether or not.

4, please check and confirm the connection between the card and the HUB distribution board, whether there is loose or plug.

5, if your screen interface definition and provided by the HUB board does not match the black screen phenomenon, please re check your jumper is loose, open circuit or short circuit phenomenon. If you think that ABCD signal has been one correspondence, please check whether the OE signal is connected correctly. (LED display manufacturers strongly recommend the use of HUB interface with the display screen definition of the distribution board)

If you grasp the above points, for the usual encounter LED screen black screen on the handy.

Optokingdom Engineer Teach You How To Calculate The Width and Height of LED Display

LED display installation of the purchase process, often involving the calculation of width and height of the display, for the convenience of customers to buy more and use LED display, Now optokingdom engineer will detailed introduce LED screen width and height calculation method for you.
hstv-p5d (3)
LED display the width and height of the calculation is in fact a rule was.

LED display with 3.75 (with indoor unit board specifications: 304mm*152mm, specifications for the 64*32 type example).

If make a (long) 4m* (high) LED display 3M, is calculated as follows:

4m/0.304m=13.16 this time to take integer (four to five), take the 13, and then use 13*0.304m=3.952m

Namely: meet the requirements of the length should be 3.952m frame aluminum or stainless steel, aluminum silver white or black, the thickness of the border is about 8mm, the width is about 3.5mm, to meet the final size LED display the above requirements are: 3.952+0.07 (and the width of the border on both sides of the =4.022m)

The same truth:

Method of calculating the height of the LED display: 3m*0.152m (unit plate height) =19.74 integer 20 (four to five homes), number 20 for unit plate, net screen size: 20*0.152=3.04m, containing the frame size: 3.04m+0.07m=3.11m.

Note: Chinese characters are 16*16 dot matrix, in general, the indoor unit board specifications for the 64*32 lattice, that is: the height of the indoor unit board can be cut in half.

Just calculate the height of the indoor LED display can take 19.5, the result is: (19.5) *0.152m=2.964m, including the size of the frame: 2.964m+0.07m (aluminum width) =3.034m

The calculation method of LED outdoor display: box type algorithm

(PH16 outdoor full-color, box size: 1024mm*768mm)

If you want to specify the width and height of the LED display, you can use the same way to calculate the same: if the customer requires 30 square meters to do such an outdoor full-color display. There is no requirement for width and height:

Usually according to the ratio of 4:3 and 16:9: if the ratio of 4:3 to design its width and height:

Calculation results: 30/12 wide open the root, and then multiplied by 4, divided by 1024mm integral. Then multiplied by the width of the box body width is the width of the screen requirements. =1.581*4=6.324/1.024=6.17: 6: display rounding, length: 6*1.024=6.144m.

The same truth: LED display height calculation method: =1.581*3=4.743/0.768=6.17, take integer 6.

Namely: the height of the display is: 6*0.768=4.608m

Display area should be: 6.144*4.608=28.32m.

What Factors Should Be Considered When Design a Wedding Stage LED Screen

LED screen HD broadcast experience more and more people in the stage design rush, not just the wedding, some annual meeting, the theme show if you use the LED screen will make the audience horizon experience more shocking. However, in today’s wedding planning, LED screen, although playing a wedding photo, playback pro-pro fragment, live wedding and other major responsibilities, but may not be more people choose. Today and talk about how to make good use of LED screen in the wedding.
LED screen stage design

Because the LED screen is rented according to the square number, in other words the greater the square the more expensive the price. In fact, the square number of LED screen is entirely depends on the stage design effect, and today we look at several LED screen wedding stage design to see how to make the best use!

The first: embedded

As the name suggests is the LED screen embedded in the background of a frame frame. The background of the stage or some, or is built with KT board background, or is used to build the background of the curtain, but no matter what kind of background LED screen is like a larger LED TV in the middle of the stage, The proportion is not a lot, just let people see the screen only.

Advantages: high-definition playback quality is good, the area is relatively small price low

Disadvantages: small enough atmosphere

The second: modular

LED screen placed in the center, with both sides of the background board and as one, forming a comprehensive design of the stage background. At present this design is more people choose to accept the LED screen.

Advantages: Large area of the screen display to make the visual enjoy more praise, and as a part of the stage background appear more harmonious.

Disadvantages: such an area of the LED screen you want to have the atmosphere of the stage background can only be placed on both sides with KT board, and pull the gauze mantle is difficult to integrate with the LED screen.

The third: single vertical

This is the land of the LED screen, the whole stage of the background is the LED screen, and no KT board, there is no other stage design elements, and all the logo, images and pictures are displayed through this large LED screen.

Advantages: the atmosphere domineering, the guests of the feast is really 360 degrees no corner can watch the contents of the LED screen

Disadvantages: What is the price in addition to the price?

The fourth: discrete

The background of the stage or the whole, or KT board design, or pull the gauze mantle design, but the LED screen is set in the background plate side, or both sides have, or only one side, a bit like the position of the projection screen , Just to temporarily play wedding photos or video and set up, and not the stage background and integration.
indoor displayjpg
Advantages: can reduce the stage background design requirements, the stage background can be more flexible use of simple materials to complete.

Disadvantages: low cost, the area can not be too small, but the use of the performance is not high, resulting in high prices low utilization.


LED screen is no doubt that high-quality, high-grade, the reason why the use of LED screen hesitant, nothing more than taking into account the price problem, but we in the wedding planning stage design process, whether to use LED screen should be considered Get more!

1, the venue space problem

If the venue is very broad, it is recommended to consider the use of a large area of the LED screen, in order to the wedding scene, wedding photos and other information clearly expressed so that sitting in the remote guests can feel the actual content of the wedding and not Think of white to a. However, if the wedding venue of the pillars are more, or the shape is not long strip but wide flat type, then do not use the LED screen is actually the role of almost.

2, stage background style

Pull the gauze mantle of the small fresh style is absolutely not suitable for LED screen this high-end tough guy appeared.

3, how much to play the content

If the preparation of the video data is not a lot, not too much wedding photos, wedding prohibition, micro-film, etc., in fact, the projection screen is also enough to support the field.

4, the cost of the problem

LED screen is rented in accordance with the area, looks like the current market price is not very cheap, whether there is no need to use the LED screen have to look at their own budget.

5, the main table set the location

Some elders because the pure unity of the main table must be set in the center of the stage, this time if the use of the LED screen, everyone in the light under the meal, a meal down estimated eye can not stand.

Common Failure Analysis and Solution of LED Video Wall

Optokingdom Engineer shares LED Display Module 7 Core Parameter Analysis

The LED display module is the core part of the display, it is equipped with a LED circuit board and the shell, and the LED lamp is arranged together are packaged according to certain rules, then add some water treatment and a product composition. With the continuous development of LED display industry and the growing demand for applications, the function and role of the LED display module can not be ignored.
full color led display screens
So, today we come to understand the LED display module under the seven parameters:

1.LED panels module color

It is the most basic parameters in the LED panels module, the application of different colors in different occasions. According to the variety of colors can be divided into single color, full-color single point of control of two.

1), monochromatic is a single color, can not be changed, then the power can work.

2), full color is single point to each module can control the color, to achieve a certain degree of time can display pictures and video effects on the number of modules. To add a full-color single point control system can realize the effect.

2.LED display module brightness

One to the brightness, we think of the word high brightness, this parameter is a parameter that people pay more attention to. Brightness in the LED inside is a complex problem, we usually say in the LED display module brightness is usually luminous intensity and transparency, is generally related to the degree of each module can be summed up.

3.LED display module light angle

No LED display module with lens light angle, mainly by the LED lamp to decide different light angle LED lamp emitting angle is different, generally provided by the manufacturer for LED lamp module angle.

4.LED display module operating temperature

The normal working temperature of the LED screen module is usually between -18 C and 58 C, if the requirements are relatively high, it is necessary to carry out special treatment, such as air conditioning or exhaust fan.

5.LED screen module voltage

It is one of the most important parameters in the LED screen module, and the low voltage module of 12V is more common. In connection with the power supply and control system must check the correctness of the voltage value, in order to power, otherwise it will damage the LED module.

6.LED module size

Usually refers to the length and width of the higher dimensions.

The maximum length of a single connection: this parameter when we do large projects with more than, it means in a series LEDscreen module, a LED screen module is connected. This is related to the size of the connection line of the LED display module. Also according to the actual situation to customize.

7.LED module waterproof level

This is mainly for outdoor, it is to ensure that the LED display module can be an important indicator of long-term work in the open air. Usually in the case of open air the best waterproof level to reach IP65.

The main reason is profit maximization.When buyer want to make more profit ,they cut price cruelly,they forget the the important quality.When seller want to get order and make more profit,they are cheating on workmanship and materials,they forget the most important quality too !
Both buyer and seller must pay attention on the quality consequences!For example,when buyer purchase 10 pcs Traffic LED Display,after 10 days they fixed them on Highway,the LED Display start to sparking ,stimulate and harm the driver’s eyes ,in this way it is very easy cause the traffic accident.So in short there is very big market require the LED Display,but because of the consumer worry about its quality,they will not choose to use the LED Display.

(II.)Price Consciousness in synchronous:
Even I do do not need to say anything,both buyer and seller must pay the most attention on the price,because they get profit from the price.
But when both buyer and seller bargain the price,pls do not forget Consciousness in synchronous.The seller must know clearly that foreign buyer must pay for sea or air freight,declear custom,pay for tax ,pay for warehouse or shop rent and staff salary.On the other hand,the buyer must know clearly that seller have to pay for material ,factory working site rent,water,electricity cost,have to pay for tax ,worker and staff salary.Both buyer and seller have to pay for expense ! But the buyer ususally cut the price sharply,the seller have to face the fierce market competition,if he does not accept this order,the other factory maybe accept this order.Then he is forced to accept this order,he take a risk and attempt to to cut corners for making little profit. Then at last happen the big accident.
For example,a HK customer buy 1pc Outdoor Aluminium Decorative LED Display from Mainland,for the cheapest price ,he lost the biggest face ! After a few days he fixed it on a facmous building,the LED Display burst into flames.It not only makes safe problem,and make the building look very ugly ! The building facade become black !

The share from Haisheng— The design of the lifting stage in Spring Festival Gala! (Chapter 2)

The characteristics and the horizontal layout of the lifting stage in Spring Festival Gala makes us very surprised, do you know the structure of the stage and the difficulties in design and installation? Now let me tell you!


Part 3: Structure of the stage

Because No.1 CCTV Studio is an existing building, the installation of the equipment just can rely on the method of “expansion” on the scene. The all single machine equipment are installed on two channels. Between the channel steel and the ground is connected by expansion. According to the characteristics of small size and difficult structure arrangement, it adopted the program which use the geared motor to drive the gears directly. The power is transmitted from the drive gear to the other pair of gears. Consequently, with the drive of the gear, the middle frame can run. At the same time, the middle steel frame, fixed steel frame and LED steel are connected together with the chain. The chain is formed into a closed chain. Because the fixed steel frame can not exercise, with the operation of the middle frame, LED steel will run. Between LED screen and LED steel frame is connected by the screws. The control of the travel and the speed of the elevator is based on an encoder which is mounted at the end of the motor.


Part 4:Difficulties in design and installation

1.Difficulties in design

The difficulty in design is the shaking of fixed steel frame. If the design is not reasonable to shake, it will bring great security risks to the show. The biggest obstacle to solve the problem is that the space is insufficient. At last, it carried out the physical trial and the measurement through the steel frame mechanical calculation tools.

  1. Difficulties in mechanical installation

Accuracy of installation position and operation precision is the difficulty in mechanical installation. The requirement of the verticality is so high after the installation of the single device. If it is skew, the lifting platform must rub each other. Seriously, it will damage to the LED screen. Because the lifting table is the vertical and horizontal arrangement, when the position is skew, it must affect the gap between front and back or left and right lifting platform. It will cause a 0 gap, too large a gap or a negative gap. Therefore, the uniformity control of the gap must be accurate between the each lift table. After the strict quality checks, the clearance of the lift is controlled within the allowable range.


The design of the lifting stage in Spring Festival Gala is innovative and scientific! As an excellent supplier in LED industry, Haisheng company has rich experience in design of the stage solution for 8 years! We offer over 500 stage projects’ devices! Our company boasts with comprehensive products lines of stage, including stage led lighting, amplifier and speaker equipment, stage led lighting consoles, dance floor LED screen, complete stage project equipment, LED ceiling display and stage rental LED display etc. We can meet your personalized requirements and provide the professional service and guide to our customers!
