Abstract
An active liquid crystal multi-colored display panel structure comprised of triangular triads of colored display pixels which are rotated 90.degree.. The display comprises a plurality of colored pixel electrodes arranged in rows and columns to form a matrix, wherein a row control line is provided every 1.5 rows of electrodes, and wherein three column control lines are provided for each two columns of electrodes. Thus, a matrix of 720.times.720 pixel electrodes requires 480 row control lines and 1080 column signal lines. The active liquid crystal display structure can be directly driven by a video source such that 480 active lines of video signal can be mapped directly onto the 720 rows of pixel elements. A switching circuit is provided for controlling the arrangement of R, G and B pixel signals to the column source lines. The triads of pixel elements provided are rotated 90.degree. to maintain high resolution while allowing a standard video signal to be directly mapped onto the display without additional electronics such as a ping-pong memory.
