Electronic Monitor for Cars

An electronic monitor for car use using a 5.9-inch diagonal full color TFT-LCD (Thin Film Transistor Liquid Crystal Display) has been newly developed and is now being manufactured. The LCD monitor has several merits when compared to a CRT (Cathode Ray Tube) monitor: reduced dimensions (especially in its depth), lighter weight and lower power consumption. This paper introduces the LCD monitor and the technologies developed for each of its element: the new LCD panel, the back light system, the signal processing circuit and the temperature compensation technology.
