Development of Toyota Electro Multivision 860175

The Cathode Ray Tube (CRT) has many superior characteristics compared to other display devices in the area of response, high-resolution, full-color and multi-display capabilities. However, CRTs commonly- used in offices or in the home have not been applicable for automobiles because they could not ensure sufficient display. performance, brightness, vibration resistance, and reliability due to the severe driving conditions of the automobile.We examined the applicability of the CRT into an automobile display system using an experimental vehicle and improved six especially important aspects such as dimensions, display appearance time, effect of magnetism, visibility, stabilization of brightness and prevention of excessive battery drain. Consequently, we developed a new display system called “Toyota Electro Multivision” and introduced it into the ‘85 Toyota Soarer, a luxury class passenger car for the Japanese market only.This report describes the details of items improved to adopt a color CRT for use in automobiles and the outline of “Toyota Electro Multivision”.
