When a physical button or a vendor Logo is provided on the terminal 100, the fingerprint sensor 114 may be integrated with the physical button or the vendor Logo.
The optical sensor 115 is used to collect the ambient light intensity. In one embodiment, the processor 101 may control the display brightness of the touch screen display 105 based on the ambient light intensity collected by the optical sensor 115. Specifically, when the ambient light intensity is high, the display brightness of the touch display screen 105 is increased; when the ambient light intensity is low, the display brightness of the touch display screen 105 is turned down. In another embodiment, the processor 101 may also dynamically adjust the shooting parameters of the camera head assembly 106 according to the ambient light intensity collected by the optical sensor 115.
A proximity sensor 116, also known as a distance sensor, is typically disposed on the front face of the terminal 100. The proximity sensor 116 is used to collect the distance between the user and the front surface of the terminal 100. In one embodiment, when the proximity sensor 116 detects that the distance between the user and the front surface of the terminal 100 is gradually decreased, the processor 101 controls the touch display screen 105 to switch from the bright screen state to the dark screen state; when the proximity sensor 116 detects that the distance between the user and the front surface of the terminal 100 becomes gradually larger, the processor 101 controls the touch display screen 105 to switch from the breath screen state to the bright screen state.
