Title:
DISPLAY DRIVING DEVICE AND METHOD, AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2018/176746
Kind Code:
A1
Abstract:
A display driving device is provided, which includes a detecting circuit, a comparing circuit coupled to the detecting circuit, and a timing control circuit coupled to the comparing circuit. The detecting circuit detects, and sends to the comparing circuit, a common voltage from each of a plurality of regions in the display panel. The comparing circuit compares the common voltage with a reference voltage and determines whether it is normal. Based on the determination result from the comparing circuit, the timing control circuit adjusts a data voltage of a region having an abnormal common voltage so as to allow a positive data voltage and a negative data voltage of the region to be symmetrical to the common voltage of the region. A display driving method based on the display driving device and a display apparatus having the display driving device are also disclosed.
