Abstract:
1. An apparatus for driving a display wherein 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 comprising: a plurality of source driver chips, each of which receives a pixel value and outputs the driving voltage corresponding to the pixel value according to a plurality of gamma voltages and comprises a gamma voltage generation circuit used to generate at least one gamma voltage and transmits the at least one gamma voltage to other source driver chips; wherein the at least one gamma voltage transmitted by each of the source driver chips is different from other gamma voltages generated by the other source driver chips, and each of the source drivers generates the driving voltage corresponding to the pixel value in accordance with the at least one gamma voltage generated thereby and the other gamma voltages generated by the other source driver chips.
