Abstract

A terminal including a screen structure and a method are provided. The terminal includes a main body including a screen panel on a screen. The terminal includes a fingerprint reader disposed in the main body and connected to a processor. The terminal also includes one or more fingerprint detection units disposed between the screen panel and the screen. The fingerprint reader is electrically connected to the one or more fingerprint detection units respectively and electrically connected to the processor. The fingerprint reader is configured to acquire detection signals from the fingerprint detection units, generate fingerprint data according to the detection signals from the fingerprint detection units and send them to the processor. The processor is disposed inside the main body, and configured to compare the fingerprint data with stored reference fingerprint data, and perform a preset control command when the fingerprint data match with the reference fingerprint data.
