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.

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.

1.Check if the graphic card settings is well or not, according to the instruction in the CD-ROM electronic file.

2. Check the basic connection of the system, such as DVI cable, network cable, the sending card and computer PCI slot, and the serial cable connection.

3. Check if  the computer and LED power supply system have met the needs or not. When the LED screen’s power is low, the LED screen flicker when it show only white color. You should use appropriate power supply according to the actual needs.

4. Check whether the green light of the sending card has a regular flashing, if flashing see next Step 6 directly, if not flashing, restart. Before entering the win98 / 2k / xp please check the green light is flashing regularly or not. If  flashing, please turn into Step2, to check if the DVI cable is connected properly. If the problem is not resolved, then there must a problem of the sending card, the video card and the DVI cable. please repeat step 3 after replacing one of them.

5. Follow the instructions of the software to set or re-install and then set until the sending card green light flashes, otherwise repeat step 3.

6.Check whether the green light (data light) of the receiving card is flashing synchronously with the green light of the sending card. If it blinks turn to Step 8, check that the red light (power) is on. If it is on please turn to Step 7, If the power supply is not on, check if the power supply is reversed or the power supply doesn’t have output. If the power supply voltage is 5V, turn off the power supply, remove the adapter and cable to try again, if the problem is not solved for the receiver card failure , Replace the receiving card, repeat step 6.

7. Check whether the network cable is connected well or too long (you must use the standard CAT5 network cable, the network cable without repeater is the longest distance and 100 meters). Check whether the cable is made according to the standard (see the system installation and setup ), If the problem is not resolved to receive card failure, replace the receiving card, repeat step 6.

8. Check if the LED screen power light is on. If not, go to step 7 and check that the interface of the adapter card matches the LED module.

(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 ! As soon as HK citizens walking along the road and look the black building feel very afraid.So when buyer and seller bargain price,pls do not forget to guarantee the quality !

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!

722644823653892023

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 share from Haisheng — The design of the lifting stage in Spring Festival Gala! (Chapter 1)

  In the Spring Festival Gala on CCTV, not only did the changeable lifting stage left a deep impression on hundreds of millions of viewers in front of the TV, but also it brought a new concept of the stage! It will bring revolutionary changes to the stage design in the future, especially the stage design of the television studio!

7odbkj954u6i0003

Part 1:Characteristics of the stage

There are four characteristics in Spring Festival Gala:

1.Work closely with actors or plot.

Whether the traditional stage exercise or not, the host or actor should stand or perform in accordance with the fixed position of the stage. When it needs the movement with the stage, the actor must in a fixed position on the stage. The stage occupied the No.1 CCTV studio in Spring Festival Gala. In addition to the area for audiences, the lifting stage which is composed of 304 lifting tables, it is full of every area where the actor will reach. So as long as the actors in the performance area, no matter where you are, the lifting stage can run with the actor according to the needs of the plot. It can change from the traditional sense of the person or the scene of the stage into a stage or landscape.

2.Fast and changeable combination.

It didn’t increase or decrease any props and scene on the stage in Spring Festival Gala. It just change the combination of the lifting platform and the video content of the LED screen. Each program has its own “scenery and props”, it can achieve them through the organic combination of the lifting platform and the change of LED screen video content! Although the change of each scene or situation just use a few seconds, it can make people to be personally on the scene and feel real!

3.Participate in performance.

Because the size of each lifting platform is small, it is up to 304 blocks. Not only the lifting stage plays the role in manned scenery, at the same time, but also it involved in a variety of performances. In the whole Spring Festival Gala, almost all the lifts are running to work in with the actors and performing to enjoy hundreds of millions of viewers. With the change of the story, the lifting platform plays a important role in performing.

4.Embodiment of scene and props.

Because the surface of the lifting platform is paved with the LED screen, and the LED screen is connected to the video control system. Therefore, when it is combined with the combination of lifting platform, it can create richer scene and props!

Part 2:Horizontal layout of stage.

No.1 CCTV Studio is a circular structure. The lifting stage is arranged in long strips. The length from front to rear is 34.835 meters. It is almost the entire length of the studio. The width from left to right is17.41 meters. The width is also exceed some theater stages. The whole performance area is all the lifting stages. The basic size of the lifting platform is 1m * 1m. There are 266 pieces of these basic lifting platforms. It accounted for a total of 87.5%. The lifting stage group is composed of four kinds of specifications.

The design of the lifting stage in Spring Festival Gala is changeable!

The technical requirements of stadium LED display

Introduction: In order to enhance the level of venues and undertake more large and medium-sized competition, the use of LED display is the rigid requirements of the stadium. Therefore, the detection methods of stadium LED display is more and more important.

The stadium was used to the filament lamp. It was gradually introduced into LED as a light source and the display content was gradually changed from the previous figures to text, pictures and videos. In the technology of LED display, the color of display, brightness and angle of view, system control technology and others have been continuously improved and widely concerned in practice.     In order to enhance the level of the venue, the use of LED display is the rigid requirements of the stadium. Therefore, the detection methods of stadium LED display is more and more important.

e62cadaa696c05bcb7df5c6dcb717a5a

Key technical indicators of LED display

The related Key technical indicators about LED display mainly includes the white color coordinates of the display , the flatness, the brightness and the uniformity, the maximum sight distance, the pixel out of control rate and the contrast and so on. The core requirement is to ensure the visual clarity and comfort from the referee and the audiences. It describes the specific technical requirements of these indicators in the following.

The flatness

The local bulge or concave will lead to appear the dead viewing angle of LED display. In order to ensure that LED display images can’t distort, it must ensure that its flatness can meet the requirements.

The maximum sight distance

For the stadium LED display, it must make audiences to meet the maximum visual range requirements. The maximum visual range requirements of LED display  refers that you can see the maximum distance of characters under the normal conditions of use.

The pixel out of control rate

It means that the ratio of pixels to total pixels which theirs luminescence state and control requirements can’t match.

e61388b06396381d8c755baab035292f

The greatest brilliancy

The brightness of LED is an important index to evaluate quality of products. The higher brightness of the screen, the better bright degree of the image. It looks clearer in the distance. But it can not exceed a certain range, otherwise it will bring visual fatigue to the audience. And it also cause a certain degree of light pollution.

The uniformity

The index of uniformity includes the pixel intensity uniformity, the brightness uniformity of display module and the module brightness uniformity. These indicators in the production process of the display screen is very scientific. It plays an important role In the product quality testing.

The highest contrast

This is an important optical performance index. Not only can it reflects the brightness of the display, but also reflects the influence of environmental illumination on display. Due to the highest contrast detection requires a certain ambient illumination requirements, it is difficult to realize in the field test. The higher contrast of the screen, the better clarity of the screen.

According to the electronic industry and the standards of sports industry, the standard technical requirements of stadium LED display are discussed in this paper.
