Abstract

The embodiment of the invention provides a display device and a driving method thereof, relates to the technical field of display, and solves the problem that the aging decay of light-emitting components in sub-pixels in a fingerprint identification area is too quick in the prior art, so that the uniformity of display brightness is effectively improved. The display device comprises a display panel, wherein the display panel comprises a substrate, and at least partial area of the display area of the substrate is the fingerprint identification area; the display area is internally provided with aplurality of sub-pixels, and each sub-pixel comprises a first light-emitting component; a plurality of fingerprint identification units are arranged on the side, away from the first light-emitting components, of the substrate, and each fingerprint identification unit comprises a second light-emitting component and at least one light sensation sensor, wherein each second light-emitting component is a micro light-emitting diode, and the projections, on the substrate, of the second light-emitting diodes and the light sensation sensors are positioned in the fingerprint identification area. The display device is used for image display.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display device and a driving method thereof. 【Background technique】 [0002] For the display panel with fingerprint recognition function, in order to better realize the full screen design and avoid the fingerprint recognition area from occupying the non-display area space, at present, the under-screen fingerprint technology can be used to reuse part of the display area as the fingerprint recognition area , and the light emitted by the sub-pixels in the fingerprint identification area is used as the light used for fingerprint identification. [0003] When performing fingerprint identification, it is usually necessary for the light-emitting elements in the sub-pixels in the fingerprint identification area to emit light with higher brightness to improve the detection accuracy, but in this way, the sub-pixels in the fingerprint identification area need to emit high-brigh...
