ABSTRACT:
A three-color backlight type display device according to the present invention is provided for reproducing a full color image with no use of color filters. In use, a composite signal is separated by a RGB decoder into R, G, and B color components which are sampled on a frame-by-frame basis and stored as a serial RGB data into a RAM. The color components of the serial data are read from the RAM with a delay of one frame after the write time and within a shorter duration for data compression. The color components of compressed form are transmitted to an LCD where each of them is allocated to form a dot pattern during a blanking period. In synchronization with the allocation of the color component, a corresponding one of the three backlights is irradiated. This action is repeated for all the R, G, and B components in a succession. Accordingly, a clear color image can be reproduced having less unwanted artifacts, e.g. color blur and persistence, which are attributed to any conventional three-color backlight type display.
