ABSTRACT:
A display device for displaying an image represented by an incoming raster scan video signal comprises a PALC display panel having a rectangular array of addressable panel elements. A frame buffer stores a frame of video and a comparator compares the incoming video signal with the frame stored in the frame buffer on a line-by-line basis. In the event that a line of the incoming video signal is different from the corresponding line of the stored frame, the line of the incoming video signal is supplied to the display panel and is used to update the corresponding line of the frame buffer. Otherwise, the line of the incoming video signal is not supplied to the display panel.
