Abstract

A display device and an operation method thereof are disclosed. The display device includes a display panel, a pressure sensor, a skin texture sensor, and a controller. The skin texture sensor and the pressure sensor are respectively coupled to the controller; the pressure sensor is configured to detect a pressing action on a display side of the display panel; the skin texture sensor is configured to detect a skin texture image of a user touching the display side of the display panel; and the controller is configured to awaken the skin texture sensor when the pressure sensor detects the pressing action. The display device reduces power consumption of the fingerprint detection.
