Terminal device and operation method thereof

Abstract

The invention relates to the field of communication and discloses a terminal device and an operation method thereof. The terminal device includes a processor, a touch screen, and an optical device for acquiring a fingerprint image. The touch screen includes a fingerprint recognition area covering the optical device. The processor is used for detecting the capacitance value of the fingerprint recognition area. When the capacitance value changes, the optical device is started to acquire the fingerprint image. The processor is also used for controlling the terminal device to unlock when determining that the acquired fingerprint image matches a pre-stored fingerprint image. The invention also discloses the operation method of the terminal device. Compared with the prior art, the terminal device and the operation method thereof have following beneficial effects: there is no need to dig a hole in the terminal device such that the fingerprint recognition function of the terminal device is achieved; and dust, vapor and particles and the like outside are prevented from entering the interior of the terminal device.

Description

technical field [0001] The present invention relates to the communication field, in particular to a terminal device and an operation method thereof. Background technique [0002] In recent years, with the continuous development of communication technology and the continuous progress of the times, terminal equipment such as mobile phones, computers, and televisions have become indispensable communication tools in people's daily life. Brings great convenience. [0003] At present, fingerprint devices are widely used in smart phones, but the fingerprint devices in the prior art are usually installed in smart phones through holes reserved in the smart phones. Moreover, the existing fingerprint devices usually use inductive capacitance to collect fingerprints; or combine the key parts of smart phones that need to dig holes and fingerprint collection into one to collect fingerprints. However, in the process of realizing the present invention, the inventor found that there are st...
