20080284794 | IMAGE DISPLAY SYSTEM AND METHOD FOR ELIMINATING MURA DEFECTS - Image display techniques for eliminating mura defects, which collects reference data and adjusts the gray levels. The image display systems comprising a plurality of pixels, a memory, and an ASIC. Each of the pixels relates to a mura compensation coefficient set. The mura compensation coefficient sets of the pixels are generated by a coefficient generator. The memory stores the mura compensation coefficient sets of the pixels. The ASIC reads the mura compensation coefficient sets from the memory. With different mura compensation coefficient sets, the ASIC serves as different mura compensation function sets. Each mura compensation function set relates to one of the aforementioned pixels and is used for transforming an original gray level to a mura-eliminated gray level to drive the corresponding pixel. | 11-20-2008 |
20090135211 | IMAGE DISPLAYING SYSTEM AND METHOD FOR ELIMINATING MURA DEFECT - Image displaying systems comprising a pixel array, a memory, a parameter selector and a compensator. The memory stores compensation parameter sets of a plurality of specific pixels of the pixel array. According to driving signals of the pixel array, the parameter selector determines a target pixel that the system is going to drive, and then determines whether the target pixel is one of the specific pixels andrequires to be compensated for mura defect. When the target pixel is one of the specific pixels and requires to be compensated for mura defect, the parameter selector outputs a memory address for retrieving the corresponding compensation parameter set from the memory. Based on the retrieved compensation parameter set and an original gray level of the target pixel, the compensator generates a compensated gray level to replace the original gray level to drive the target pixel. | 05-28-2009 |
20100066913 | BRIGHTNESS ADJUSTER, ADJUSTMENT METHOD, AND ELECTRONIC SYSTEM UTILIZING THE SAME - A brightness adjuster generating an image output to a panel, which displays the corresponding image according to the image output. The image output includes a red output signal, a green output signal, and a blue output signal. The brightness adjuster includes a determination unit, a calculation unit, and a digital to analog converting unit. The determination unit determines a main input signal according to a red input signal, a green input signal, and a blue input signal. The calculation unit adjusts the red, the green, and the blue input signals according to the main input signal. The digital to analog converting unit transforms the adjusted red, the adjusted green, and the adjusted blue input signals into the red, the green, and the blue output signals. | 03-18-2010 |
