Patent ID: 8106930

Claim:
An image display system, comprising a plurality of pixels, each relating to a mura compensation coefficient set; a memory, storing the mura compensation coefficient sets of the pixels; and an ASIC, retrieving the mura compensation coefficient sets from the memory and forming different mura compensation function sets with different mura compensation coefficient sets, wherein each mura compensation function set is used for transforming an original gray level of the corresponding pixel to a mura-compensated gray level that is used in driving the pixel; wherein the mura compensation coefficient sets are generated by a coefficient generator comprising: a plurality of sensing units, sensing the pixels and outputting sensed data; an average luminance measuring instrument, measuring average luminance of all of the pixels; and a processing unit, transforming the sensed data to luminance data based on the average luminance, wherein the luminance datum and the sensed datum follow the following equation: L=L AVG ·( G/G AVG ) r , where: L represents the luminance datum, L AVG represents the average luminance of all of the pixels, G represents the sensed datum, G AVG represents the average value of the sensed data of all pixels, and r represents an adjusting factor, dependent on a sensed data—actual luminance linearity; wherein the processing unit provides at least one test gray level to test the pixels and generate the mura compensation coefficient set of each pixel according to the relationship between the test gray level and the corresponding luminance datum.
