    Abstract: In a method of generating correction data for a display device, measured tristimulus data at a maximum gray level are obtained, measured luminance and color coordinate profiles are obtained based on the measured tristimulus data, a target color coordinate profile is determined based on the measured color coordinate profile, measured red, green and blue maximum luminances of each pixel are obtained, a maximum target luminance of the each pixel is determined such that red, green and blue luminances of the each pixel become lower than or equal to the measured red, green and blue maximum luminances, respectively, a final target luminance profile is determined based on the measured luminance profile and the maximum target luminance of the each pixel, and correction data may be generated and stored in the display device based on the final target luminance profile and the target color coordinate profile.

    Abstract: A display apparatus includes a display panel, a gate driver, a data driver and a driving controller. The display panel is configured to display an image based on input image data. The gate driver is configured to output gate signals to gate lines of the display panel. The data driver is configured to output data voltages to data lines of the display panel. The driving controller includes a first compensation lookup table and a second compensation lookup table which are configured to compensate the input image data. The driving controller is configured to select one of the first compensation lookup table and the second compensation lookup table based on a first color shift and a second color shift and to apply the selected one of the first compensation lookup table and the second compensation lookup table to the input image 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.
