Abstract:
A method for data driving of a display, which is used to convert image signals into corresponding voltages so as to charge pixels of the display via data lines, comprising the following steps:a pre-selection step for dividing each binary image data composed of c bits into an MSB part P composed of a bits and an LSB part Q composed of b bits, wherein c=a+b, and selecting a base voltage for each pixel among a set of pre-determined voltages according to the MSB part P of the associated image data; a pre-charging step for charging multiple data lines simultaneously to the base voltages of the pixels, respectively; a post-selection step for selecting a corresponding voltage for each pixel according to the base voltage of the pixel and the LSB part Q of the associated image data; and a post-charging step for charging multiple date lines in turn to the corresponding voltages of the pixels, respectively.
