Abstract

The invention discloses a fingerprint unlocking method for display equipment and the display equipment, and the method comprises: a touch chip sending a first interrupt signal to a drive chip and sending a second interrupt signal to a micro-control processor according to a first awakening instruction sent by a pressure sensor when the pressure sensor detects a pressure signal located a preset region of a touch screen; the driving chip sending a first display instruction for indicating to display the unlocking interface to the touch screen according to the first interrupt signal, so that the touch screen displays the unlocking interface according to the first display instruction; the micro-control processor sending a second wake-up instruction to the fingerprint sensor according to the second interrupt signal, so that the fingerprint sensor collects fingerprint information in a fingerprint collection area of the unlocking interface according to the second wake-up instruction; and the micro-control processor unlocking the display device after determining that the fingerprint information is successfully matched with pre-stored fingerprint information. In this way, nodes and unlockingtime of a fingerprint unlocking path of the display device are reduced, and therefore the physical examination of a user is improved.

Description

technical field [0001] The invention relates to the technical field of AMOLED display, in particular to a fingerprint unlocking method of a display device and the display device. Background technique [0002] With the advent of the era of full-screen smartphones, in order to facilitate fingerprint unlocking on the full-screen, more and more full-screen smartphones are now equipped with off-screen fingerprint technology. [0003] Due to the active matrix organic light emitting diode (Active Matrix Organic Light Emitting Display, AMOLED) display, which has the characteristics of bendability, high contrast, low power consumption, etc., therefore, more and more full screens of smart phones are AMOLED displays. Screen. [0004] However, due to the self-illumination of the AMOLED display screen, in the fingerprint unlocking process of general smartphones, there are many nodes in the fingerprint unlocking path, which takes a long time and cannot meet the needs of fast unlocking, w...
