Abstract:
A mura compensation apparatus for an organic light emitting diode (OLED) display includes a calculator and a mura compensator. The calculator is configured to calculate a non-maximum-luminance demura offset value of a pixel of the OLED display for a determined gray level on the basis of a gamma value, a maximum-luminance demura offset value of the pixel of the OLED display for a relocated gray level and a non-maximum luminance value of the OLED display. The mura compensator is configured to perform mura compensation on the pixel of the OLED display by the non-maximum-luminance demura offset value for the determined gray level.
