Problems solved by technology

[0004] However, since the photoelectric sensor occupies a small area of ​​the panel and is set in a specific fingerprint recognition area, the convenience of fingerprint recognition is greatly limited; in addition, because the current display screen tends to be thinner and lighter, it is necessary to reduce the Small photosensors take up space inside the display panel

Abstract

The invention provides a display panel, a fingerprint identification driving method and a display device. The display panel comprises: a substrate; a plurality of pixel units located on the substrate,wherein each pixel unit comprises a plurality of sub-pixels arranged in an array and a fingerprint identification unit, each sub-pixel comprises a pixel driving circuit and a light-emitting device electrically connected with the pixel driving circuit, the fingerprint identification unit comprises a fingerprint identification circuit integrated with a photosensitive sensor, and the fingerprint identification circuit is electrically connected with the light emitting device and the pixel driving circuit. Part of the light-emitting devices of the display panel can be independently controlled to emit light to provide a light source for identifying fingerprint information for the photosensitive sensor in the fingerprint identification unit, so that any area of the display panel can provide a light source fingerprint identification area for the photosensitive sensor, and the fingerprint identification area is increased; and the user experience of the product is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a driving method for fingerprint recognition, and a display device. Background technique [0002] Currently, off-screen fingerprint recognition technology is widely used in mobile display terminals. The off-screen fingerprint recognition technology includes capacitive, optical and ultrasonic. Among them, the optical fingerprint recognition scheme is one of the current mainstream recognition technologies. [0003] In an OLED display using an optical fingerprint recognition scheme, the photosensor module is usually arranged in a specific area under the panel, and the fingerprint information is obtained by using light to penetrate the gap between the sub-pixels of the OLED. Since this solution has high requirements on the light transmittance of the panel, it is necessary to specially design the fingerprint recognition area of ​​the panel to improve the li...
