Thermal Analysis of Edge Illumination Type LED Backlight with Heat Pipe

Abstract:

This paper reports on thermal characterization of edge illumination type LED backlight integrated with heat pipes. Heat pipe is integrated with the panel by phase change flattening and expanding process. Thermal capabilities, including the steady-state working temperature and the temperature uniformity along the panels with heat pipes and without heat pipes are compared and analyzed. Results show that the steady-state working temperature on the panel with heat pipes is 1~6°C lower than that on the panel without heat pipes under power range of 15W to 51W of the LED arrays. And the temperature uniformity along the panel with heat pipes is controlled within 2.0°C.
