Device and method for mura correction

Abstract:

A device and method for correcting mura within a display device. The device may include a display driver that includes lookup table circuitry, correction amount calculation circuitry, and mura correction circuitry. The lookup table circuitry is configured to calculate a second grayscale value for a second display brightness value (DBV), the second grayscale value being determined to achieve a brightness level corresponding to a first grayscale value and a first DBV. The correction amount calculation circuitry is configured to calculate a mura correction amount based on a mura correction data for the second grayscale value and the second DBV. Further, the mura correction circuitry is configured to perform a mura correction on input image data by using the mura correction amount.
