Abstract
The present invention provides a display control method of a display panel, a display module, and a display device. Pulse widths of first pulses corresponding to non-display phases in one frame period in an emission start signal are at least partially different, so that pixel driving circuits adjust light-emitting durations of light-emitting devices corresponding to each display phase according to emission control signals. Accordingly, a display brightness of each light-emitting device can be adjusted within one frame period, and a flickering problem can be alleviated.
