A method for preventing misoperation in a capacitive touch screen mobile phone call and its mobile phone

Abstract

The invention discloses a method for preventing error operation in talk of a capacitive touch screen mobile phone and the capacitive touch screen mobile phone. A hardware interrupting module is set in the mobile phone, and a screen locking key is pressed down; when the mobile phone is in a talk state, the hardware interrupting module is triggered to judge that the mobile phone is in an activated state or a dormancy state; if the mobile phone is in the activated state, the hardware interrupting module shuts down the backlight of a mobile phone screen, a display screen module stops outputting data to the mobile phone screen, the screen refreshing operation is stopped, and a capacitive touch detection module is shut down; and the method is applied to the mobile phone. The hardware interrupting module for judging the state of the mobile phone is increased in the mobile phone, and the screen locking key is operated, so that the function of accurately locking the mobile phone screen or activating the mobile phone screen is realized, mechanical structures of a proximity sensor and an infrared transmitting tube are canceled, the space of the mobile phone is released, the design difficulty of the appearance and the structure of the mobile phone is reduced, and the manufacturing cost of the mobile phone is lowered.

Description

technical field [0001] The invention relates to the communication field, in particular to a method for preventing misoperation of a capacitive touch screen mobile phone during a call and the mobile phone thereof. Background technique [0002] At present, touch-screen mobile phones have become the mainstream mobile phones for applications, and the user experience of capacitive touch-screen mobile phones is the best. When a user makes a call, the screen is in contact with the face or head for a long time, which is likely to cause erroneous operations. The best solution is generally to set a proximity sensor on the mobile phone to detect that the mobile phone is in a call state. If the mobile phone is close to the head or face during the call, the mobile phone will lock the screen of the mobile phone to prevent the user from misoperation during the call. [0003] Such as figure 1 As shown, a proximity sensor 110 is generally used on a mobile phone with a capacitive touch scree...
