Abstract:
1. A picture quality controlling method, comprising: determining a charge characteristic compensation data that compensates a charge characteristic of a link sub-pixel which is electrically connected to a defect sub-pixel and a normal sub-pixel that is adjacent to the defect sub-pixel in a display panel, wherein the defect sub-pixel and the normal sub-pixel have a same color and are electrically connected each other via a link pattern to charge a same data; judging a first display surface and a second display surface, which are different in brightness from each other, by supplying a test data to the display panel to measure a brightness of the display panel, wherein the first display surface is a defective area and the second display surface is a normal area; determining a first compensation data which compensates a brightness of the first display surface; modulating the test data of the first display surface using the first compensation data; determining a second compensation data that corrects a brightness of a bordering part inclusive of a part of the first display surface and a part of the second display surface between the first and second display surfaces by supplying the modulated test data to the first display surface; adding the first compensation data and the second compensation data to calculate a summed compensation data; storing the charge characteristic compensation data and the summed compensation data in a memory; adjusting a video data, which is to be displayed in the link sub-pixel, using the charge characteristic compensation data stored in the memory; and adjusting a video data, which is to be displayed in the first display surface and the bordering part, using the summed compensation data that is stored at the memory, wherein the first compensation data has a same or different compensation value for pixels which are horizontally adjacent in at least a part of the first display surface, and wherein the second compensation data is determined to have a different compensation value from each other for vertically adjacent pixels and to have a different compensation value from each other for horizontally adjacent pixels in at least a part of the bordering part.
