Analysis of Thermal Distribution for LCD-TV Using Infrared Camera

Demand of a LCD-TV is remarkably increasing with development of the LCD technology in these days. However, there are thermal problems to improve efficiency for the LCD-TV. Thus, the thermal problems such as convection and conduction heat transfer characteristics have been analyzed for the LCD-TV using an IR (Infrared) camera. Measured temperatures in an outer side of the front panel have been compared with results of an inner side of the front panel using the IR camera and T-type thermocouples, respectively. Equations have been derived for the temperature distribution of the inner side of the LCD panel by developed multiple regression methods including variables for ambient temperatures and measured outer temperatures of the front panel of the LCD-TV.
