By performing detection in this way, the detection can be made more accurate.

In order to facilitate the user's use, the above functions can also be turned on and off. For example, the function of switching between the corresponding modes can be selected by turning on or off in the setting item of the terminal. Preferably, in the above embodiment, an area may be previously set in the capacitive touch screen for detecting a change in current of the capacitive touch screen caused by an external object without contacting the capacitive touch screen. This area can be part of the capacitive touch screen or it can be the entire capacitive touch screen.

The following is a description of a call mode switching as an example in conjunction with a preferred embodiment.

In the preferred embodiment, a solution for detecting the distance of a human face from a mobile phone through a capacitive touch screen and automatically switching between the handheld and hands-free calling modes is provided. For a capacitive touch screen, when the human body is connected to the capacitive screen working surface When touched, a coupling capacitor is formed at the contact point, and a small current flows into the human body at the contact point. This current flows out from the four corners of the capacitive screen, and the control chip determines the contact point according to the current flowing out of each corner. position. In general, the capacitive screen can detect that the human body is very close to the screen without touching the screen. In this preferred embodiment, this is utilized to provide sensitivity by increasing the sensing area. For example, a larger area on the capacitive touch screen can be set to sense the proximity of the face.

In the preferred embodiment, the distance of the face (or human ear) from the handset is determined based on the capacitive screen sensing the facial contact surface. If it detects proximity, it switches to the hand-held call (ie, the normal call mode), and detects that it is switched to the hands-free call (ie, the hands-free call mode), eliminating the user's manual selection step. This function can be turned on or off by selecting it in the terminal settings.

In the preferred embodiment, after the touch screen detects that the distance between the face (or the human ear) and the mobile phone is close, the capacitive touch screen reports the distance data to the call module, and the call module sends the distance according to the distance value (assuming that the proximity is 0 and the distance is 1). The distance message data is sent to the audio control module. The audio control module receives the message, parses the message data, and selects the call audio channel according to the message value. 0 Select the handheld channel, 1 select the hands-free channel.

4 is a flow chart of controlling hands-free and hand-held call switching according to a preferred embodiment of the present invention. The flow embodies an embodiment of a touch screen detecting a face distance to implement a hands-free and hand-held automatic switching mode. As shown in FIG. The process includes the following steps:

In step S401, the call is connected, including the calling or called.

Step S402, the call module opens an area detection function of the touch screen, and is used to detect whether the face area is close to the mobile phone. The high-sensitivity touch screen can detect the signal of the skin at 1cm, and the touch screen can cyclically detect the distance of the face.

In step S403, the touch screen reports the distance value detected by the current time to the calling module, and uses 0 to indicate proximity and 1 to indicate to be away.

In step S404, the call module determines whether the automatic switching function has been turned on in the setting item. If it is already open, continue with the following process; if it is not, the automatic switching process is not performed.

Step S405, the automatic switching function is turned on in the setting item, and the calling module sends a message to the audio module.

Step S406, the audio module selects a call mode according to the received message value. If it is close to the message, select the handheld call mode, and if it is away from the message, select the hands-free call mode.

There is no need to increase the hardware cost by the preferred embodiment, and the preferred embodiment can be used as a differentiated innovation point of the mobile terminal to improve the user experience.
