Abstract
The embodiments of the disclosure provide a source drive IC, a display device and a drive method therefor. The source drive IC comprises: a control selection module, a solid color grayscale control module and a non-solid color grayscale control module. The control selection module may be configured to receive a timing control signal inputted by a timing controller, and determine according thereto whether a current drive image is a solid color grayscale image, in response to determining that the current drive image is a solid color grayscale image, send the timing control signal to the solid color grayscale control module, and in response to determining that the current drive image is a non-solid color grayscale image, send the timing control signal to the non-solid color grayscale control module. The non-solid color grayscale control module may, according to the received timing control signal, obtain multiple sets of data voltages.
