Abstract:
A method and apparatus for overdriving pixel elements to a desired voltage. A display device comprises a pixel array and overdrive circuitry to determine a current pixel value for a first pixel element of the pixel array and a target pixel value for the first pixel element. The overdrive circuitry is further configured to determine a first voltage to be applied to the first pixel element to cause the first pixel element to transition from the current pixel value to the target pixel value by a first instance of time. The first voltage is determined based at least in part on a position of the first pixel element in the pixel array. The display device further comprises a data driver to apply the first voltage to the first pixel element before the first instance of time and a backlight to illuminate the pixel array at the first instance of time.
