COMPENSATION DEVICE FOR NON-UNIFORM REGIONS IN FLAT PANEL DISPLAY AND METHOD THEREOF
First Claim
1. A compensation device for non-uniform regions, used in a flat panel display for eliminating the negative impact of non-uniform regions in a panel on display of an video signal, the compensation device for non-uniform regions comprising:
- a database, for storing a location information of non-uniform regions obtained according to a test result;
a non-uniform-region determining unit, for determining whether the video signal falls in a non-uniform region pixel or a normal-region pixel according to the location information of non-uniform regions in the database; and
a digital non-uniform-region processing circuit, comprising a non-uniform-region compensation unit, wherein according to a determination result of the non-uniform-region determining unit, the non-uniform-region compensation unit in the digital non-uniform-region processing circuit properly compensates the video signal through digital processing.

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.
