Abstract
A display substrate, a display panel, and a manufacturing method and a driving method of a display substrate are provided. The display substrate includes a base substrate, a pixel circuit, and a photosensitive unit. The pixel circuit and the photosensitive unit are on the base substrate, the pixel circuit includes a first transistor, and an orthographic projection of the photosensitive unit on the base substrate at least partially overlaps with an orthographic projection of the first transistor on the base substrate.
Claims18
A display substrate, comprising:
- a base substrate, a pixel circuit, and a photosensitive unit,
- wherein the pixel circuit and the photosensitive unit are on the base substrate,
- the pixel circuit comprises a first transistor, an orthographic projection of the photosensitive unit on the base substrate at least partially overlaps with an orthographic projection of the first transistor on the base substrate, and the first transistor is configured to perform a display operation.
A method for driving a display substrate, wherein the display substrate comprises a base substrate, a pixel circuit, and a photosensitive unit, the pixel circuit and the photosensitive unit are on the base substrate, the pixel circuit comprises a first transistor, and an orthographic projection of the photosensitive unit on the base substrate at least partially overlaps with an orthographic projection of the first transistor on the base substrate;
- and the method comprises:
- in a first phase, applying a first voltage to the photosensitive unit to bias the photosensitive unit and allowing the photosensitive unit to convert an optical signal into an electrical signal;
- and
- in a second phase, applying a second voltage to the photosensitive unit to allow the photosensitive unit to be turned on, and allowing the pixel circuit to drive a light-emitting component to emit light.
