The invention discloses a fingerprint identification method of a display panel, the display panel and a display device. The display panel comprises a fingerprint identification area; the fingerprint identification area comprises N sub-fingerprint identification areas; and each sub-fingerprint identification area comprises M detection areas. The fingerprint identification method comprises the following steps: in a scanning period, each fingerprint identification unit performs fingerprint identification, wherein the scanning period comprises N frame scanning time periods; in the ith frame scanning time period, the light emitting units of the M detection areas of the ith sub-fingerprint identification area are driven to emit light, and the fingerprint identification units of the M detection areas of the sub-fingerprint identification area are driven to perform fingerprint detection, wherein the M detection areas of the (j + 1)th sub-fingerprint identification area and the M detection areas of the jth sub-fingerprint identification area are arranged in a one-to-one correspondence manner, and the corresponding detection areas in the N sub-fingerprint identification areas are sequentially arranged along the first direction. According to the technical scheme provided by the invention, the problem that the fingerprint identification efficiency is influenced due to more stray light andcrosstalk in the existing fingerprint identification process can be solved.
Description
technical field [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification method of a display panel, a display panel and a display device. Background technique [0002] With the vigorous development of the full-screen mobile phone market, the application of fingerprint technology under the screen has gradually become the mainstream standard configuration of the industry. Under-screen fingerprints can be roughly divided into three types: capacitive fingerprint recognition, optical fingerprint recognition and ultrasonic fingerprint recognition. Among them, optical fingerprint recognition has the advantage of high sensitivity. In order to enhance the accuracy of fingerprint recognition, a large part of the electronic The device uses optical fingerprint recognition to realize fingerprint detection under the screen. [0003] During the fingerprint identification process, the pixel area of the fingerprint id...
