Abstract:
The present invention discloses an apparatus for driving a display in which each pixels of the display receives a driving voltage and a common voltage, and a luminance of each pixel is determined by a difference between the received driving voltage and the common voltage. The apparatus comprises a plurality of source driver chips, each of which receives a pixel value and generates the driving voltage corresponding to the pixel value according to a plurality of Gamma voltages, wherein at least one of the Gamma voltages is generated by one of the source driver chips.
