摘要： The invention provides a system for varying the transmittance of light through selected portions of a media on which images are displayed, the system including an image display panel, an image display source for projecting images on the media, LC-based, variable transmittance optical (VTO) media, a light sensor for measuring ambient light, and a signal generator connected to the VTO media for applying voltage to portions of the media at levels determined and controlled by the sensor, whereby the transmittance of light through the portions of the media is varied in accordance with the prevailing ambient light. A method is also provided.
