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

The invention discloses a screen unlocking method, and also discloses corresponding screen unlocking system and mobile terminal. The screen unlocking method comprises the following steps of: in a screen locked state, using an infrared receiving tube of the mobile terminal to receive the infrared light reflected back after being transmitted from an infrared transmitting tube of the mobile terminal; using a proximity sensor of the mobile terminal to execute detections successively so as to obtain multiple infrared light intensities within predetermined time, converting the light intensities into digital information, and transmitting the digital information to a baseband processor of the mobile terminal; using the baseband processor of the mobile terminal to receive multiple pieces of digital information converted into corresponding light intensities, and calculating the current light intensity variation condition according to the multiple pieces of digital information converted into corresponding light intensities; and judging whether the current light intensity variation condition belongs to a first mode of correspondingly unlocking the screen, if so, unlocking the screen. By the pattern, the method, the system and the mobile terminal can realize unlock control on the screen by recognizing gestures through the proximity sensor, and the method, the system and the mobile terminal are simple and easy to realize.

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...
