Embodiment Construction

[0016] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, an embodiment of the mobile phone of the present invention includes:

[0018] Infrared photosensitive element 110;

[0019] Infrared photosensitive components are electronic components sensitive to infrared rays, and their electrical parameters will change significantly under infrared radiation. A common example is an infrared photoresistor. Infrared photoresistors are made of semiconductors. The conductivity of semiconductors depends on the number of carriers in the conduction band of the semiconductor. When the photoresistor is illuminated, the electrons in the valence band absorb photon energy and then jump to the conduction band to become free electrons. At the same time, holes are generated, and the appearance of electron-hole pairs makes the resistivity smaller. The stronger the light, the more photogenera...

Abstract

The invention provides a mobile phone which can prevent false triggering of a touch screen. The mobile phone comprises an infrared photosensitive element, a first light guide structure, a detecting unit and a control unit, wherein an opening of the first light guide structure is positioned near the touch screen and used for guiding the light to the infrared photosensitive element; the detecting unit is used for detecting the electrical parameter change of the infrared photosensitive element; and the control unit is used for locking or unlocking the touch screen according to the measured electrical parameter change of the infrared photosensitive element. The invention also provides a method for preventing the false triggering of the touch screen, which comprises the following steps of: detecting the electrical parameter change of the infrared photosensitive element; and locking or unlocking the touch screen according to the electrical parameter change of the infrared photosensitive element. The invention constructs an optical sensing circuit by discrete component photosensitive resistance so as to recognize whether the touch control of the screen is a false action or not; and the design cost of the system can be greatly reduced when the misoperation is solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method for solving misoperation of a touch-screen mobile phone during a call and the mobile phone. Background technique [0002] At present, there are more and more mobile phones with touch functions. During a call on a touch-screen mobile phone, the screen will touch the face, so it will also cause some misoperation problems, which will affect the user experience. The traditional solution is to sense the distance between the screen and external objects through an integrated light sensor or other integrated proximity switches, so that the software can judge whether to respond to external touch operations, but the cost of this solution is relatively high. Contents of the invention [0003] An embodiment of the present invention provides a mobile phone that solves misoperation of the touch screen mobile phone during a call, so as to prevent the touch screen mobile phone f...
