Abstract

The present disclosure relates to a display driving method, a display driving chip, and a display device. The display driving method includes: determining whether an abnormal signal is detected in feedback; if so, switching to a common voltage regulation display mode until the abnormal signal disappears, wherein, in the common voltage regulation display mode, the display grayscale of the pixel circuit is controlled by the common voltage, so that an alarm image is displayed. Compared to display methods controlled by the source driving circuit, the approach according to the present disclosure can significantly reduce the complexity of control processes and the number of required memory units.
