Lcd projection display for vehicles

摘要

A liquid crystal display system (10) for use in a vehicle such as an automobile. The LCD display system (10) generally includes a long life high-efficiency lamp (22) and reflector system (24) for producing a light which is transmitted or transferred into the passenger compartment of the vehicle through a flexible light transmitting element (14) such as an integrating light pipe. The output of the light transmitting element (14) is directed onto the face of a liquid crystal display light valve (16). The light valve (16) produces an image which is subsequently enlarged and projected onto a display screen (20) using an optical projection lens assembly (18). A number of devices and techniques for reducing high ambient light conditions on the screen (20) are also disclosed.
