ACTIVE OPTICAL DEVICE LIGHT-EMISSION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2020/192501
Kind Code:
A1
Abstract:
Disclosed by the embodiments of the present application is an electronic device, comprising: a display screen, a display control circuit, an active optical device, and an optical control circuit, said active optical device being located below said display screen; said display control circuit is used for controlling the refresh of the display screen and outputting a synchronization signal to the optical control circuit; the optical control circuit is used for receiving said synchronization signal and controlling the active optical device to begin emitting light after a predetermined first delay time at a time corresponding to the synchronization signal, such that after the active optical device finishes emitting light and after a predetermined second delay, the display control circuit refreshes to a row of at least one row on the display screen corresponding to the active optical device.
