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 concerning issue for large size LED is that the temperature increases with the time goes on, and it often accompanies by the variation of the wavelength and the reduction of the brightness. Therefore, the overall performance of 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 temperature and time graph of 32 inches LCD TV. At the beginning of the first 20 minutes, the heat will increase rapidly with time, but then the heart increases very slow with time, which we name it the stabilization phase and the light performance is relatively stable. Therefore, we can conclude that LED backlight module can perform excellent stability of temperature as long as the LED package and the thermal management are good.
