Problems solved by technology
[0003] In the existing display device with fingerprint identification function, when the light emitted by the fingerprint identification light source is reflected by the touch body, it will irradiate multiple fingerprint identification units, causing each fingerprint identification unit to receive the reflected light from its corresponding position. , it also receives crosstalk light from other positions, which affects the accuracy of fingerprint recognition by the fingerprint recognition unit

The embodiment of the invention discloses a fingerprint identification method of a display device, the display device and electronic equipment. The method comprises the following steps: in each fingerprint identification sub-period, controlling pixel units in each fingerprint identification unit group within a first distance L1 from an ith row and a jth column of fingerprint identification units to be lightened; in each fingerprint identification sub-period, indicating that the distance between the fingerprint identification units in the ith row and the jth column of the adjacent fingerprint identification unit groups is greater than a second distance L2; in each fingerprint identification sub-period, acquiring a fingerprint signal acquired by the fingerprint identification unit in the ithrow and the jth column in each fingerprint identification unit group; wherein L2 is 2 * L1, X and Y are positive integers, i is a positive integer greater than or equal to 1 and less than or equal toX, and j is a positive integer greater than or equal to 1 and less than or equal to Y. According to the technical scheme provided by the embodiment of the invention, the interference of crosstalk light on the fingerprint identification unit can be reduced, and the fingerprint identification accuracy of the display device is improved.
Description
technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a fingerprint identification method for a display device, a display device, and electronic equipment. Background technique [0002] Fingerprints are inherent to each person and are unique. With the development of technology, a variety of display devices with fingerprint recognition functions appear on the market, such as mobile phones, tablet computers, and smart wearable devices. Among them, the display panel in the display device mainly includes two types: liquid crystal display panel (Liquid Crystal Display, LCD) and organic light-emitting display panel (Organic Light-Emitting Diode, OLED). [0003] In the existing display device with fingerprint identification function, when the light emitted by the fingerprint identification light source is reflected by the touch body, it will irradiate multiple fingerprint identification units, causing each fing...
