Embodiment

[0021] Embodiment: a kind of method that prevents the misoperation in the conversation of capacitive touch screen mobile phone, its working procedure is as follows:

[0022] 1) The mobile phone powers up the touch screen, and the touch screen starts the communication module and the Sensor (capacitive touch screen sensor) scanning module. After confirming that the communication with the main control of the mobile phone is normal, it enters the main loop.

[0023] 2) In the main loop, continuously scan the Sensor to determine whether the touch screen has detected signal data, if not, continue to scan the Sensor, if yes, the touch screen detects signal data, then calculate some data required by the mobile client based on the signal data (such as coordinates, gestures), and according to the Sensor’s signal strength, signal distribution and other data, it is judged whether it is the data of large-scale false touches. The data of large-area false touches refers to more than 1 / 4 of th...

Abstract

The invention discloses a method for preventing misoperation of a capacitive touch screen during phone call. The working process is as follows: (1) detecting signal data by the touch screen; (2) processing the signal data, and calculating data required by the mobile phone; (3) determining whether the signal data contains large-area faulty-contact data or not; (4) determining whether faulty-contact prevention command is sent out or not; (5) sending a command to a master control of the mobile phone to open or close the faulty-contact prevention function; and (6), sending corresponding data of coordinates, gestures and the like to the master control of the mobile phone according to the communication protocol. According to the method provided by the invention, the function which only can be achieved by a proximity sensor and an infrared emission pipe in the prior art can be achieved by redesigning the working process of the capacitive touch screen without the need of hardware equipment, so that the space of the mobile phone is released, the design difficulty in appearance and 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 field of mobile communication, in particular to a method for preventing misoperation during a call of a capacitive touch screen mobile phone. Background technique [0002] At present, mobile phones with capacitive touch screens have become the mainstream mobile phones, and when users make calls, the screen is in contact with the face, which is likely to cause erroneous operations. The general solution for the current capacitive touch screen is to install a proximity sensor on the mobile phone to prevent misoperation caused by the contact between the screen and the face during the user's call, and the proximity sensor also needs to be used in conjunction with an infrared light-emitting tube to increase The manufacturing cost of the mobile phone is reduced, and the size of the sensor, infrared light-emitting tube and peripheral devices needs to be placed near the earpiece, which increases the difficulty of designing the appe...
