Abstract

The invention provides a fingerprint identification method and terminal. The method is suitable for a device comprising a liquid crystal display (LCD). A backlight region of the LCD is provided with an infrared light-emitting diode (LED); and all space or a specific region between a liquid crystal layer of the LCD and lower substrate glass is provided with an infrared sensor. The method comprises the following steps: the device obtains infrared light information through the infrared sensor; and the device identifies fingerprint information according to the infrared light information, thereby realizing fingerprint identification of the infrared light information reflected by user fingers by utilizing the infrared sensor. The infrared sensor and the infrared LED are integrated in the LCD, thereby improving utilization rate of the LCD space, preventing occupation of the whole machine space and realizing non-contact fingerprint identification.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a fingerprint identification method and device. Background technique [0002] With the development of science and technology, terminals are becoming more and more popular. Fingerprint recognition is more and more widely used on terminals. For example, by setting the user's fingerprint as unlocking information, it provides users with business services such as online payment with higher security. [0003] In the prior art, the identification area for fingerprint identification needs to be set on the back of the terminal or the opening of the front cover, and the fingerprint sensor is installed inside the corresponding position, and a supporting bracket is added to fix the fingerprint sensor, so that the fingerprint sensor on the back of the terminal A fingerprint identification area is formed, or a fingerprint identification area is formed at the key set in the open...
