ABSTRACT:
Disclosed is a digital signal processing architecture for a flat panel display having non-uniform regions, which is not by means of materials, optical films or fabrication processes. Therefore, the manufacturing cost and complexity of the flat panel display are not negatively affected. In the digital signal processing architecture, a test is performed on the panel for identifying all pixel locations in non-uniform regions and non-uniform types. Then, input video signals are compared with data about the relative non-uniform regions for determining whether the video signal falls in a normal-region pixel or a non-uniform region pixel. Then the non-uniform compensation on the video signal falling in the non-uniform region pixel is based on the non-uniform type, so that the video signals displayed on the panel are not negatively affected.
