Embodiment 1

[0025] Such as figure 2 As shown, the implementation method of the terminal touch button in Embodiment 1 of the present invention includes:

[0026] Step 21: Obtain a detection result of the capacitance of a preset area on the surface of the terminal housing by a capacitive touch detection module, the capacitive touch detection module is integrated in the fingerprint recognition module of the terminal;

[0027] Step 22: According to the detection result, judge whether the change value of the capacitance is greater than a preset threshold;

[0028] Step 23: When the change value of the capacitance is greater than a preset threshold, perform a predefined operation corresponding to the detection result.

[0029] Among them, the preset area in the first embodiment of the present invention is preferably 3, corresponding to the menu function, fingerprint identification and HOME function, and return function respectively; the capacitor can be a PCB board (Printed Circuit Board, pri...

Embodiment 2

[0036] The implementation method of the terminal touch key provided by the second embodiment of the present invention integrates the function of the touch key into the fingerprint recognition chip, as shown in image 3 As shown, the functions of touch buttons and fingerprint recognition are realized through the fingerprint recognition chip.

[0037] Among them, the working principle of the terminal touch button is as follows: Figure 4 As shown: there is capacitance between any two conductive objects, and the two exposed copper areas between the PCB board or FPC board are the two plates of the capacitor, which is equal to a capacitor, which itself has a certain capacitance value. When the finger d of the human body is close to the PCB board, due to the conductivity of the human body, the size of the capacitance will be changed. When the change of the capacitance value exceeds a certain threshold, it can be considered that a finger touches the fingerprint chip IC.

Abstract

The invention provides a terminal touch button implementation method and a terminal. The terminal touch button implementation method comprises the following steps: acquiring a detection result of a capacitive touch detection module on the capacitance of a preset area of the surface of a terminal shell, wherein the capacitive touch detection module is integrated in a fingerprint identification module of the terminal; according to the detection result, judging whether the change value of the capacitance is greater than a preset threshold value; when the change value of the capacitance is greater than the preset threshold value, executing a predefined operation corresponding to the detection result. According to the scheme, a terminal touch button function is realized and the problems that a design flow is complex and the cost is increased caused by the fact that a touch button and a fingerprint chip are arranged on the front surface of the terminal to realize a touch function in the prior art are solved by acquiring the detection result of the capacitive touch detection module on the capacitance of the preset area of the surface of the terminal shell, judging according to the change value of the capacitance according to the detection result, and executing the predefined operation when the change value of the capacitance meets a requirement.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a method for realizing a touch button of a terminal and a terminal. Background technique [0002] With the development of smart phones, the display form of large-screen touch control of mobile phones has been recognized by consumers, and ultra-thin mobile phones have been pursued by consumers. Such as figure 1 As shown, in addition to the HOME and fingerprint identification button a on the front of most Android smartphones, there are also touch buttons such as the menu button b and the return button c. In order to meet the needs of consumers, the fingerprint function is also becoming popular, because fingerprint recognition not only meets the higher security requirements of mobile smart devices, but also meets the needs of users for convenience. In order to achieve a better user experience, the fingerprint chip also needs to be placed on the front of the phone. [...
