Abstract:
1. A display device for displaying frames of video information comprising: a display panel comprising a plurality of pixels arranged in a pixel matrix, wherein the pixel matrix is divided into regions of 16 adjacent pixels each; a source driver connected to the display panel to provide data signals to pixels in each column of the pixel matrix; an inconsistency correction calculation section connected to the source driver for correcting variations in brightness of each pixel; a memory connected to the inconsistency correction calculation section for storing a correction value for each pixel and an average of correction values for the 16 adjacent pixels of each region, wherein in a group of four frames, for each region, a first group of four pixels are corrected using a stored pixel correction value and 12 pixels, different from the first group of four pixels, are corrected using the average of correction values for the 16 adjacent pixels of the region in a first frame of each group of four frames, a second group of four pixels, different from the first group of four pixels, is corrected using a stored pixel correction value and 12 pixels, different from the second group of four pixels, are corrected using the average of correction values for the 16 adjacent pixels of the region in a second frame of each group of four frames, a third group of four pixels, different from the first group of four pixels and second group of four pixels, is corrected using a stored pixel correction value and 12 pixels, different from the third group of four pixels, are corrected using the average of correction values for the 16 adjacent pixels of the region in a third frame of each group of four frames, and a fourth group of four pixels, different from the first group of four pixels, second group of four pixels and third group of four pixels, is corrected using a stored pixel correction value and 12 pixels, different from the fourth group of four pixels, are corrected using the average of correction values for the 16 adjacent pixels of the region in a fourth frame of each group of four frames.
