A new generation of energy-saving LED Display Screen Come out

UNIT LED has Launched a new generation of energy-efficient led display screen than the traditional full-color led display board  for more than 50% energy saving, on-site without having to install air-conditioning and other auxiliary cooling equipment, better meet the energy requirements of environmental protection.

led display board

For example, 100 square meters of PH20 outdoor led display, in accordance with the use of 14 hours a day, 365 days a year calculation. Energy-efficient than conventional led display panel to conserve electricity year hundreds of thousands of degrees, assuming that industrial use of electricity in accordance with 1 yuan / degree calculation, then the annual electricity savings in more than 100,000 yuan, that is to save electricity per square meter 1,000 yuan annual above.

A new generation of energy-saving LED video display at the same time have the following outstanding properties:

1. With a single point of brightness and color correction, brightness uniformity of ≤ 5%
2.64-order programmable current gain adjustment, on-line single-point detection
3.16 for data processing, the brightness is lowered without loss of gray-scale.
4. The new mask design, no dust is not water, the entire screen in terms of black bright screen, when there was no detectable module feeling
5. With a temperature control function, effectively improve the cooling fan efficiency
6. Upgraded version of full-color control system.

LED Video Display’s Inspection

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

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!

The Capability Of LED Display Screen Control

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.
E, Animation: can play with ANIMATORPRO, 3DStudio software produced by the second, three-dimensional animation, and supports the use of compression of the AVI signal acquisition cards, sea Sheng interface package with convenient interface, a wealth of material, physical libraries, and advanced rendering technology, can produce high-quality three-dimensional animation, creative advertising to become the reality of life.
So,When you are looking for a LED Advertising Display, LED Control system is important for the reliable and Clear Image Showing.
