Title:
DIGITAL CONTROL DRIVING METHOD AND DRIVING DISPLAY CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/169672
Kind Code:
A1
Abstract:
Disclosed by an embodiment of the present invention are a digital control driving method and a driving display control device. In the method, in utilizing a means of digital control, an image frame is equally divided by bit into K subframes, wherein the occupation time of each subframe is equal, but the driving duration of each subframe is not equal; according to a special transmission mode, the K subframes drive a display panel to display within one frame time of the image frame; and a transmission voltage value comprises only two values, which correspond to the luminescence and the non-luminescence of pixel points on the display panel. Therefore, in the embodiment of the present invention, by means of utilizing digitally controlled driving, a source driver chip only outputs two types of gray-scale voltage values, and a driving TFT only operates in an on or an off state, which may effectively prevent the influence of drift of a driving TFT Vth.
