Abstract
The invention relates to a microdisplay system that utilizes a small high resolution active matrix liquid crystal display with an illumination system and a magnifying optical system to provide a viewfinder in a electronic image record system such as a digital camera or video camera. The matrix display can be transmissive or reflective using sequential lighting. The system can use an alternating common voltage which allows reduced power consumption. In addition an internal heating system in the display allows the system to be used at low temperatures.
