Terminal equipment control method, system, terminal equipment and computer device

The invention provides a terminal equipment control method, a system terminal equipment and a computer device. The terminal equipment control method comprises the steps that when it is detected that an optical fingerprint identification area of a touch screen of the terminal equipment is touched and operated, an application processor of the control terminal lights up the optical fingerprint identification area of the touch screen; when the optical fingerprint identification area is lit up, an optical fingerprint identification module of the terminal equipment is controlled to collect user fingerprint information in the optical fingerprint identification area; whether or not the user fingerprint information is matched with preset fingerprint information is judged, and if yes, the terminal equipment is unlocked. According to the terminal equipment control method, the optical fingerprint identification area does not need to keep normally on, so that energy consumption of the terminal equipment on the fingerprint
