LED’s luminous color and efficiency is related to the production of LED’s materials and processes,Now the Widely used red, green, and blue. Because the LED’s voltage is low (only 1.5-3V), LED can show the different colors power by low voltage which itself has impact-resistant, anti-vibration, long life (100,000 hours), so in large led display device,There is no other display way can match with led display board.

The most critical parts of Full color led display is LED. For three reasons:

First, LED is the largest number of key components that used for full color led display screen, the number is several housands leds per square meter. For example, ph10mm 2R1G1B, the density is: 10,000 dots/m2, and each dots have 2 red led, 1 green led,1 blue led. so for ph10mm 2R1G1B, we use 40,000 leds/m2.

Second, LEDs determine the optical properties of the whole led display panel, it affect the evaluation of viewer whom we will show the advertising to;

LED is the most critical components for led display sign, it equals to a computer CPU. LED options have been decided more than 50% of the entire quality of the led digital display. If you can not choose a good LED, the other parts of led display panel can not make up for deficiencies no matter how good the quality they are.

The red and green LED produced as a pixel color led display screen;we call double color led display or dual color led display, the red, green, and blue LED(RGB) as a pixel color led screen,then we call full color led display or color led display.Whether using LED for monochrome led sign, dual color led display or full color led screen,if we want to display images then we need to adjust the luminance and intensity of each LED, the adjustment of the level is the gray scale. The higher gray level, then can showing images of the more delicate, the color has more abundant, and the corresponding led display control system is also more complex. Generally, 256 gray scale images, color transition will be very soft, while the 16-level grayscale color image, color transition line is very obvious. Therefore, the full color LED screen have to require 256 gray scale.

LED Display’s Working Principle

led display screen is a High-tech products that optical and computer technology in one.

LED product’s performance characteristics

led video display should have: animation features. Required LED display’s dots corresponding to the same area showing of computer’s monitor, we can it dot to dot with controlling PC. The function of text led display. Required text display stable, clear crosstalk; grayscale function. it Requires a detailed specification in the levels specified in gray. TV led video display except with animation, text display, grayscale functions, should be able to show the TV, s-videos,dvd players. rental led display aslo need the function to show the Live show,with hanging installation for different applications,and flight case for easy transportation.

LED display can be classified according to the following conditions:

1. By The Usage of the environment, it classified to outdoor led display and indoor led display.

2.By the Display color,it is divided into single-color LED display, dual-color LED display and full-color LED display. By gray-scale level,it can be divided into 16,32,64,128,256 gray LED display panels.

3.By led display board performance,it isdivided to led message signs, graphic LED display, computer led video display ,TV LED video display,led information display,etc.

4.indoor LED display be used for single color led sign, it can be divided into ph3mm,ph4mm,ph5mm,ph6mm,ph7.62mm,ph8mm,ph10mm,ph12mm,ph16mm,ph20mm; outdoor LED displays by using pixel pitch,it can be divided into: ph8mm,ph10mm,ph12mm,ph16mm,ph18mm,ph20mm,ph25mm,ph30mm,ph31.25mm,ph40mm.

led displays- Five elements to inspect the specific quality and parameters of led display screen:

1, failure rate

As color led display is composed to the group of thousands and even hundreds of thousands of red, green, and blue LED pixel,The failure of any color LEDs will affect the overall visual effect of led display wall. In general, according to industry experience, In the beginning of LED display assembly to the aging of 72 hours before shipment should be no higher than three ten thousandths failure rates (defined as the LED itself causes failure).

2, anti-static capability

LED is a semiconductor device tha is sensitive to static electricity, static electricity can easily lead to failure, The anti-static capability is essential to the life of the led display screen. In general, LED failure of human static model test voltage should be less than 2000V.

3,Attenuation characteristics

The LED’s brightness decay rate depends on Advantages and disadvantages of LED chips, auxiliary materials and packaging technology good or bad . In general, the 1000 hours, 20 mA at room temperature after the light testing, the red LED should be less than 10% attenuation, blue, green LED of the attenuation should be less than 15%. Red, green, blue attenuation consistency have the great influence on future white balance for color led display, thereby it affect the color’s fidelity of the led display sign.

4,Brightness

LED brightness is an important determinant of the led display board’s brightness. The higher LED brightness, the greater use of current margin of saving power, good stability to maintain LED. LED has a different point of view the value of the chip where the brightness has been set, the smaller the angle, LED, the more light, but the smaller viewing angle of led display panel. Generally,we should make sure the led display board has the viewing angle of 110 degree horizontal and 70 degree vertical,of course,different space and different application, should find a balance point on the brightness and viewing angle.

White Balance is the important technology for LED Video display, it means: R:G:B is 3:6:1. to achieve the best color uniformity!

According to the needs of our customers, summed up a set of their own method of calculation. Customers who need the brightness and display distance between two points,they can tell us ,we can serve our customers all-round way for the customer’s led screen to make a perfect light distribution program. To facilitate the following presentation, I will introduce a few terms and definitions of indoor led screen and outdoor led display.
White Balance: The deployment of three colors to a vision of a white process. Deployment can be divided into two elements: color and brightness.
1: Set the fixed conditions: temperature, voltage, use the power cord.
2: Set the color targets and range (tolerance), generally refers to target colors X, Y values.
3: for white brightness adjustment.
The total brightness of color mixture is equal to the composition of mixed colors of various colors of light known as the brightness of the aggregate sum of the law.
Color appearance of the same light, regardless of whether their spectral components, as in the color mix has the same effect, that is, those who are visually the same color are equivalent, and this law can be derived color instead of law.

The Expo2010 in Shanghai, LED plays an important role, It is widely used in the indoor led display and outdoor led display, LED signage, LED Message Board, Performance, Concerts,Big Event..etc. Now, The entire Expo Exhibition is the Biggest LED Showroom in the whole world.
