Embodiment Construction

[0037] The following will clearly and completely describe the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0038] refer to figure 1 as shown, figure 1 It is a schematic structural diagram of a display panel with an under-display fingerprint chip. The optical fingerprint chip 13 is pasted and fixed on the back of the display panel 11 through optical glue 12. When a finger 10 touches the display area of ​​the display panel 11 corresponding to the optical fingerprint chip 13, After the light emitted by the display panel is reflected by the finger 10 , it enters the optical fingerprint chip 13 ...

Abstract

The invention discloses a display panel, a control method thereof and electronic equipment, a photosensitive element connected with a pixel circuit is arranged in the display panel, image display and fingerprint detection can be carried out in a time-sharing manner, the photosensitive element is controlled to be disconnected with a first node based on a first time sequence signal in an image display period, and the first node is controlled to be disconnected with a second node based on a second time sequence signal. The control driving transistor, the first reset transistor and the compensation transistor control the light-emitting element to perform light-emitting display; and in a fingerprint detection period, based on a second time sequence signal, switching the conduction state of the photosensitive element and the pixel circuit, controlling the driving transistor, the first reset transistor and the compensation transistor, collecting a fingerprint signal related to a detection signal of the photosensitive element, and outputting the fingerprint signal through the first reset transistor. The photosensitive element is integrated in the display panel, and a multiplexing pixel circuit is used as a fingerprint detection circuit, so that the thickness of the panel is reduced, and the fingerprint detection precision and accuracy are improved.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, and more specifically, relates to a display panel, a control method thereof, and electronic equipment. Background technique [0002] With the development of science and technology, more and more electronic devices with display functions are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable important tool missing. The main component of an electronic device to realize a display function is a display panel. [0003] In order to meet people's ever-increasing functional requirements, electronic devices have a fingerprint detection function. In the prior art, generally, an optical fingerprint chip is attached and fixed directly on the back of the display panel to collect fingerprint information. [0004] In the prior art, the under-display fingerprint chip design in which an optical fing...
