Embodiment Construction

[0024] see figure 1 , an embodiment of the screen unlocking method of the present invention includes:

[0025] Step S101: Make the infrared receiving tube of the mobile terminal receive the infrared light emitted from the infrared transmitting tube and reflected back;

[0026] The mobile terminal lights up the screen in the locked screen state in response to the user's key operation. At this time, when the mobile terminal is in a screen-locked state, the infrared receiving tube in the mobile terminal is made to receive the infrared light emitted by the infrared transmitting tube and reflected back. In practical applications, when an object approaches the proximity sensor, the infrared light emitted by the infrared emitting tube is reflected by the object and received by the infrared receiving tube. When there is no object approaching, the infrared receiving tube cannot receive the infrared light emitted by the infrared emitting tube. Usually, a barrier is set between the in...

Abstract

Disclosed is a method for screen unlock; also disclosed are a corresponding system and method for screen unlock. The method for screen unlock comprises: in a state that a screen is locked, making an infrared receiver transistor of a mobile terminal to receive a reflected infrared light transmitted by an infrared transmitter transistor of the mobile terminal; making a proximity sensor of the mobile terminal to successively detect and acquire multiple infrared light intensities within a predetermined time, to convert the light intensities into digital information and to transmit same to a baseband processor of the mobile terminal; making the baseband processor of the mobile terminal to receive multiple pieces of digital information converted from the corresponding light intensities, and to calculate and acquire a current light intensity variation in the light intensities on the basis of the multiple pieces of digital information converted from the corresponding light intensities; determining if the current light intensity variation belongs to a first mode corresponding to unlocking of the screen, if yes, then unlocking the screen. With the method, the present invention allows the proximity sensor to identify a gesture, thereby implementing unlock control of the screen, and is easy to implement.

Description

technical field [0001] The invention relates to a screen unlocking method, system and mobile terminal. Background technique [0002] At present, with the popularization and development of various mobile terminals, the functions of mobile phones are becoming more and more abundant, and the user experience brought to people is also getting better and better. Usually, in order to prevent the mobile terminal from being accidentally turned on when it is in the standby state, the mobile terminal will automatically make the display screen in the standby state be in a locked working mode. When it is necessary to open the display screen of the mobile terminal in the locked working mode, it is usually through sliding unlocking or unlocking with a fixed keyboard, etc., and the method is relatively simple. [0003] In addition, in order to improve the user experience, some more creative unlocking methods have emerged, such as facial recognition unlocking and fingerprint unlocking. Alt...
