碩士 === 中原大學 === 機械工程研究所 === 107 === Automotive display is not only used in the system of car navigation. The diversified applications go with the trend of internet of vehicle technology, autonomous vehicle, and automobile entertainment. The increasing demand also helps the growing of the automotive display market. The design specifications of automotive display are becoming rigorous, such as the sharpness presentation, color saturation, and panel downsizing solution. All of the above may lead to the overheating of the LED in the backlight module display. Therefore, how to design the backlight module to improve the heat dissipation efficiency is an important issue. The purpose of this study is to investigate the influence of materials of the backlight module on the thermal performance. Without affecting the structural strength and restriction of the appearance of the backlight modules, the different thickness of thermal tape and different materials of the metal frame were used. The modules were tested in the constant temperature and humidity machine to inspect the dissipation performance of each module.
