Compensation hardware device for non-uniform regions in flat panel display

Abstract

The present invention discloses a compensation hardware device for non-uniform regions in a flat panel display. The hardware device processes the flat panel display having non-uniform regions through digital signal processing, instead of by using 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 non-uniform-region compensation unit is used to process a video signal falling in a non-uniform region pixel, such that the non-uniform regions may not negatively affect the video signal displayed on the panel.
