Abstract: A method of driving a display apparatus including generating first gamma correction data of input data using a first gamma look-up table (“LUT”), determining a Mura correction value of the first gamma correction data, adding the Mura correction value to the input data to generate added input data, generating second gamma correction data of the added input data using the first gamma LUT, and driving a pixel in the display panel using the second gamma correction data of the added input data. The Mura correction value is determined after the gamma correction data is generated, and the generating of the added input data is performed prior to any gamma correction being performed on the input data.

Abstract: A method of reducing a total, per device, measurements taking time in a calibration system that uses a sensor array that serially reports out its readings and a data processing unit that needs to receive the reported out readings in good order before allowing an under-measurement first display device to advance away from a measurements taking station includes the step of not driving the first display device with all of required full screen test images where each is a full screen display of only a respective one of a predetermined minimum number of grayscale values produced as a minimum number of needed full screen sample images and; in place of at least a first plurality of the not-produced full screen images, driving the under-measurement first display device with a partial screen multi-pattern that presents a plurality of different grayscale values including ones not presented by those of all of the full screen test images that are used to drive the under-measurement first display device. The serially reported out readings from the sensor array for the partial screen multi-pattern and for the full screen test images are obtained and used to generate virtual full screen sample images based on the obtained partial screen multi-pattern and for the full screen test images.
