Abstract
A display panel which may include a plurality of sub-pixel units (1) and a plurality of photosensitive detection units (2) corresponding to the plurality of sub-pixel units (1) respectively. Each of the plurality of the photosensitive detection units (2) may include at least two photosensitive sensors (21).
Claims18
A display panel comprising:
- a plurality of sub-pixel units;
- and
- a plurality of photosensitive detection units corresponding to the plurality of sub-pixel units respectively;
- wherein one of the plurality of the photosensitive detection units comprises at least two photosensitive sensors;
- photosensitivity of each of the at least two photosensitive sensors in a same photosensitive detection unit is different from one another;
- the at least two photosensitive sensors in the same photosensitive detection unit is configured to determine brightness of light emitted by a sub-pixel unit based on photosensitivity of the at least two photosensitive sensors.

A driving method of a display panel, wherein the display panel comprises:
- a plurality of sub-pixel units;
- and
- a plurality of photosensitive detection units corresponding to the plurality of sub-pixel units respectively;
- wherein one of the plurality of the photosensitive detection units comprises at least two photosensitive sensors;
- and
- the driving method comprises:
- acquiring electric signals outputted by the at least two photosensitive sensors in a photosensitive detection unit corresponding to a sub-pixel unit;
- determining an actual value of brightness of light emitted by the sub-pixel unit based on photosensitivity of the at least two photosensitive sensors in the photosensitive detection unit and the electric signals outputted by the photosensitive sensors;
- and
- adjusting a driving voltage of the sub-pixel unit based on the determined actual value of brightness of light emitted by the sub-pixel unit and a calibration value of brightness of the sub-pixel unit.
