Title:
PIXEL DRIVING CIRCUIT AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2021/196382
Kind Code:
A1
Abstract:
A pixel driving circuit capable of integrating functions of an electronic device in a display panel to realize full-screen display, comprising a light-emitting driving circuit, a photosensitive driving circuit, a micro light-emitting diode (M1), and a photoelectric conversion element (M2). When the pixel driving circuit is in a display mode, the light-emitting driving circuit drives the micro light-emitting diode (M1) to perform light-emitting display, when the pixel driving circuit is a photosensitive display mode, the photosensitive driving circuit drives the photoelectric conversion element (M2) to generate a photocurrent, and when the photocurrent is received by the micro light-emitting diode (M1), light-emitting display is implemented.
