To improve the LED (Light Emitting Diode) efficacy is the major consideration when the backlight and lighting
system are implemented. An important source of poor efficacy come from the chip process or heat dissipation. White
LED used blue chip with phosphor is the current solution and inadequate for the tunable color temperature system.
The use of RGB (Red, Green and Blue) LED with smart control is presented in this study. The resulting coupled
optical and thermal shows the better performance when it is synthesized in conjunction with a degree of color mixing
