Abstract

The invention discloses a fingerprint detection method and an electronic device. The fingerprint detection method comprises the following steps: obtaining a control instruction for indicating to collect fingerprints; executing the control instruction and controlling at least one display pixel unit corresponding to a fingerprint acquisition area in a display screen to be in a fingerprint identification mode, wherein the fingerprint acquisition area is a partial region in the display screen; and sensing fingerprint information of fingers in the fingerprint acquisition area through the at least one display pixel unit in the fingerprint identification mode. According to the technical scheme, the at least one display pixel unit corresponding to the fingerprint acquisition area in the display screen is reused to carry out fingerprint identification, and the fingerprint information of the fingers in the fingerprint acquisition area is sensed through the at least one display pixel unit in the fingerprint identification mode, so that the display screen no longer needs to be bored to install a fingerprint identification module additionally, mechanical strength of the display screen is ensured, production process is simple and production cost is low.

Description

technical field [0001] The present invention relates to the technical field of display devices, and more specifically, to a fingerprint detection method and electronic equipment. Background technique [0002] With the continuous advancement 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 important part of people's daily life. Indispensable and important tool. A display screen is a main component for an electronic device to realize a display function, and a liquid crystal display panel is one of the display screens commonly used in electronic devices today. [0003] In order to ensure the security of user information, existing electronic devices are generally integrated with a fingerprint identification module. But at present, the fingerprint identification module and the display screen of the existing electron...
