The Uniformity of LED Background Lighting

Filed under: LED Display Screen — Tags: , , , , , — admin @ 12:30 am

Now, we are discussing about the Uniformity of LED Background Lighting.

LED back light is divided into two categories: white-light LED and three-color LED. Regardless of the kind of classification is the source of the LED background wall, which the distribution of emitters is very uniform, while the CCFL backlight tube usually strip, L or U-type, no matter what kind of shape, their distribution in relation to the case of LED back lighting and not very uniform, so have a light-emitting LED backlight more uniform characteristics.

So,when you are looking for a LED Product for Stage or concert, LED Background wall or LED Strip Screen is a good option for you!
This is a LED Background Lighting project for Stage, it is a good application, they are good uniformity. and if you are interested in it,please contact with us to get more information about LED Display Products.

LED Video Display’s Inspection

Filed under: LED Display Screen — Tags: , , , , , — admin @ 7:03 pm

The way of how to inspect the led video display:

1 . LED display board hardware environment:Using our eyes to check the hardware of led matrix display.

2 . LED displays software environment: using the eyes to check the software of  LED RGB display environment.

3 . Structure and appearance: Using eyes to check the structure and appearance for led displays.

4 . Safety requirements:
(1) Connect the ground to check the LED display screen.
(2) Checking  the security tags with visual inspection of the security tag  LED screen.
(3) LED Screens-to-ground leakage current at 1.1 times rated power supply voltage, testing LED display power cord between the metal frame-to-ground leakage current.
(4) According to the Anti-electric intensity LED display’s power switch position, power input or with the metal frame structure of hit pieces of metal between the imposition of 1500V (AC RMS), 1min.
(5) High Temperature  of LED display Panel in the workplace after an hour ,then test the working temperature.

6.  Color uniformity:Using eyes or software to test  the uniformity of LED display sign.

7.  LEDs out of control: Using eyes or software to check the leds that is out of control or different colors.

8.  Consumption: Power on the  full color LED display ,then Measuring the power consumption.

More ways will be coming for LED Display boards.

ESD for LED Display Screen Manufacturing

Filed under: LED Display Screen, LED Technology — Tags: , , , , , — admin @ 11:35 pm

The Electro Static Discharge of the LED Display Manufacturer:

In recent years, LED display technology in our country matures, applications become the trend of widespread and universal. However, most manufacturers of LED display production is not yet fully equipped with the real capacity of these products, which products to the LED display Screen has hidden, and even affect the entire market. How to standardize the production, how to produce the true sense of the low attenuation, long-life LED Video display of products? In this paper, the production process from the Outdoor LED display electrostatic protection point of view, to discuss the process and the harmful effects of the electrostatic protection methods.

The Reason of ES(Electro Static):

From the micro level that, according to atomic physics theory, when the material in a neutral state of equilibrium, electric, electronic material due to different contacts of the gains and losses arising from electronic to physical loss of power balance, the phenomenon of static electricity.

From a macro perspective, the reasons are: the friction heat between objects to stimulate electron transfer; object contact and separation between the resulting electron transfer; electromagnetic induction caused by the imbalance of surface charge distribution; friction and the combined effect of electromagnetic induction.

Electrostatic voltage is from different types of material separated from each other and have contact with. This effect is well-known friction from electricity generated by friction between the voltage depends on the characteristics of the material itself. As the LED screen in the actual production process is the human body and related components of the direct contact and indirect contact with static electricity. Therefore, in accordance with the characteristics of the industry we can do a number of targeted preventive measures electrostatic

So,When you check the LED Display manufacturer  you need to check there ESD equiment, if they pay more attention on ESD for the LED Display Screen, you will have a more reliable quality and long lifetime LED Display Panel for your Advertising!

This Article is to describe the capability of LED Display Control System
1.LED Screen in the design and production will be fully taken into account the characteristics of the local climate and environment, in order to improve product reliability, the Company to ensure that the components in the rated temperature range of use, large LED screen with good ventilation cooling performance, and has dust-proof, anti – salt spray, mildew, anti-static electricity, lightning protection and other functions.
2, A high standard of LED display control system:
A, the gray level of world-class control technology, with a capacity of 4096 gray-scale LED  display processing and video noise reduction.
B, with the display scanning frequency of 300HZ.
3, The stability of high-quality LED Video display:
Our company have many years of LED software and hardware development experience in the video receiver circuits, memory circuits, high-speed read and write circuits, LED display control circuit in the scan have been conducted to deal with interference and ensure uninterrupted signal.
A, through the network connection screen, remote control and easy to use.
B, signal transmission cable using a dedicated computer communication cable (in line with the standard RS-422A), the realization of the computer screen body and the synchronous communication.
C, text: text to play a wide range of various fonts, font and text messages, but also achieve the flip, move, spin, snow, scroll, blinking, etc. more than ten kinds of LED  display Panel.
D, computer image information: You can play different formats of graphics, image files. Such as: BMP, TGA, TEXT, GIF and so on.

New Pattern LED Production Technology

Filed under: LED Technology — Tags: , , — admin @ 11:58 pm
New Pattern LED Production Technology for LED Display Lighting Industry.
Chinese Academy of Sciences, Changchun Institute of Optics, Fine Mechanics and Physics on November 14 in Changchun announced that after 10 years of scientific research, they successfully developed the world’s first “integrated three-in-one” type LED display, this new technology will change the current LED displays screen the world market by the “three-in-one table paste” the dominant pattern.
It was learned that the LED Video Display ’s core technology is a completely independent intellectual property rights “for large-scale mass production of LED display Screen brightness, color-by-point correction of the same technology” to subvert the results of previous international LED display panel design, making China the world’s first stand in the forefront of LED display industry.
According to industry, currently in the world market dominated by “three-in-one table paste” LED display, and its shortcomings are: the use of table affixed to the LED display technology, in the production process to go through the one-tube packaging and the second two welding processes, welding of the second more stringent temperature requirements. High temperature die easily damaged, the temperature is too low loose soldering easily. Second welding in the manufacturing process in the production of high precision equipment, welding temperature, surface mounting machine for precision and use of welding materials, board thickness, etc. have a great impact on its reliability.
So, let us looking forward to this new led technology for LED Display Lighting industry. it will be a great to energy saving, and a good furture for Green world.
