Title:
DRIVING METHOD AND APPARATUS FOR LIGHT-EMITTING SUBSTRATE, AND DRIVING CHIP AND TIME SEQUENCE CONTROL PLATE
Document Type and Number:
WIPO Patent Application WO/2023/124301
Kind Code:
A1
Abstract:
A driving method for a light-emitting substrate. The driving method comprises: receiving a frequency modulation signal (S10); generating a frequency modulation synchronization signal which corresponds to the frequency modulation signal (S20); when a rising edge of the frequency modulation synchronization signal is in a write stage of a light-emitting unit set into which a light-emission data signal is last written within the previous frame period, generating an auxiliary synchronization signal (S30); and on the basis of the auxiliary synchronization signal, controlling a write stage of a light-emitting unit set into which the light-emission data signal is first written within the current frame period to be staggered with the write stage of the light-emitting unit set into which the light-emission data signal is last written within the previous frame period (S40), wherein the light-emitting unit set into which the light-emission data signal is last written within the previous frame period and the light-emitting unit set into which the light-emission data signal is first written within the current frame period belong to the same light-emitting unit group.
