Abstract

The embodiment of the present invention discloses a terminal device, a fingerprint collection method and related products. The method includes: turning on M light sources among the N light sources, and the light emitted by the M light sources is used to irradiate the user's fingerprint, The M is a positive integer; the fingerprints of the users illuminated by the light emitted by the M light sources are collected. By adopting the embodiment of the present invention, the service life of the screen of the mobile phone can be guaranteed under the premise of using the fingerprint function.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for collecting fingerprints and related products. Background technique [0002] Nowadays, the fingerprint function has become the standard configuration of smartphones, and it can even be said that mobile phones without fingerprint functions cannot keep up with the times. Fingerprint sensor (also known as fingerprint Sensor) is a key device to realize automatic fingerprint collection. According to the sensing principle, fingerprint sensors are divided into optical fingerprint sensors, semiconductor capacitive sensors, ultrasonic sensors, etc. [0003] The optical fingerprint sensor uses the principle of refraction and reflection of light. The angle at which the light emitted by the light source is refracted on the uneven lines of the fingerprint on the surface of the finger and the light and darkness of the reflected light will be different. The optical device of C...
