Temperature control technology on rugged airborne TFT-LCD

Some problems on temperature control technology of the rugged airborne TFT-LCD are discussed and the operation temperature of -43℃～＋71℃ for the airborne TFT-LCD is achieved. Based on the characteristic analysis of TFT-LCD, some methods of the circuit heating are designed to heat LCD module with ITO and heat CCFL with heating wire. Thus the airborne TFT-LCD can be started up and operated under low temperature. Based on thermal design methods, the cooling scheme for the airborne TFT-LCD operating under high temperature is also proposed. The operation temperature range of the ruggedized airborne TFT-LCD is increased with the automatic temperature control system.
