The Temperature of LED Backlight Module Remains Stable While Time Goes On

The thermal problem is the big bottleneck for the development of LED backlight. The most concerned issue for large size LED is that thermal increases with the time going on, and it often accompanies by the variation of the wavelength and the reduction of the brightness. Therefore, the overall performance stability of backlight module is very important for both middle size laptop computer and large size liquid crystal television.

The combo RGB 3 in 1 top view LED and bottom backlight module with PCB material not only presents the excellent color performance and stability, but also efficiently manages the thermal problem.  From the image above, we can see the test result of 32 inch LCD TV temperature and time graph. At the beginning of the first 20 minutes, the heat will increase rapidly with time, but the then the heart increases very slow with time which we call the stabilization phase and the light performance is relative stable.  So we can conclude that LED backlight module can perform excellent temperature stability as long as the LED package and the thermal management are good.
