How to choice the best LED screen for you
The importance of the LED to display is just the same as the engine to the car, the compressor to the air-condition. To chose a high-quality LED is very important. Generally, we think there are four key points for LED display closely connected with the LED quality. There are: brightness and viewing angle, even and clarity, out of control dots and life span, power.
1, Brightness and Viewing angle(top-tech LED displays)
For the top LED: horizontal view angle is 110 degree, vertical view angle is 50 degree., the brightness in this viewing angle is: gree:4000mcd, red:1500mcd, blue:1000mcd
2, even and clarity
mainly affects the even of the screen. The main factor to limit the clarity of led display is the even but not physical distance. The dot to dot, module to module mean is very important.
The factors caused uneven is: led capacity parameter is variant , the process of producing and installation is not so delicate, module and PCB design is nonstandard.
How to solve the Inconformity of the led parameter ? they are two ways: one is re-divide the parameter, two is use post-dot –to- dot –adjust to improve the uniformity.
In some distance, improve the even of the screen is to improve the clarity of the screen.
3, the screen out of control
Main reason is led failure
The reason why led easy to fail:1, quality 2, wrong use. 3 whether (high degree, low degree, fast change degree), static
4, life-span
LED life-span decide the screen life-span
We said LED life-span decide the screen life-span not means LED life-span equals to screen life-span. screen working not means every LED full load working. When the screen play video, its life span should be 6-10 times of the LED light. LED working in minimum power can prolong its life span too.
How to make LED life-span longer?
Chose good material, enlarge chip square, lower power density, balance the power density, lower the heat-resistance, shoes anti-UV(ultraviolet ray) envelope material, release hit , lower working current
