Embodiment 1

[0064] A detection method of a capacitive touch screen of an electronic device, the detection method is executed by the electronic device, and the electronic device includes a capacitive touch screen, such as figure 1 As shown, the detection method includes:

[0065] Step 101, storing reference data of a capacitive touch screen in the electronic device.

[0066] Step 102, detecting the capacitive touch screen and acquiring detection data.

[0067] Step 103: Compare the detection data with the reference data, if the difference between the detection data and the reference data does not exceed the difference range, then the capacitive touch screen passes the detection, if the detection data and If the difference of the reference data exceeds the range of the difference, the capacitive touch screen fails the detection.

[0068] Through the detection method of this embodiment, even if the capacitive touch screen has been assembled to the electronic device, it can detect whether t...

Embodiment 2

[0070] In this embodiment, the following improvements are made on the basis of Embodiment 1. The reference data in this embodiment includes the reference value of the sensing channel of the capacitive touch screen, and the detection data includes the sensing channel of the capacitive touch screen. detection value. For self-capacitive touch screens, the sensing channel refers to the single sensing channel of the self-capacitance itself, which is distributed in the ActiveArea (active area) of the screen and the function button area below the screen; for mutual-capacitive touch screens, the sensing channel includes TX drive channel and RX receiver Channels are distributed in the ActiveArea of ​​the screen and the function key area at the bottom of the screen.

[0071] Such as figure 2 As shown, the detection method of the present embodiment comprises:

[0072] Step 201, storing the reference value of the sensing channel of the capacitive touch screen in the electronic device. ...

Embodiment 3

[0082] The detection method of this embodiment is basically the same as the detection method of Embodiment 2, the difference is that in this embodiment, the reference data includes the reference value of the touch node of the capacitive touch screen, and the detection data includes the reference value of the capacitive touch screen The detection value of the touch node. The capacitive signal obtained by the sensing channel of the whole screen of the capacitive touch screen is divided into (X, Y) squares. For example, if a touch screen uses 12 RX and 20 TX, there are 12*20=240 grids, each grid Corresponds to a touch node.

[0083] Such as image 3 As shown, replace step 201 with step 201': store the reference value of the touch node of the capacitive touch screen in the electronic device.

[0084] Step 203 is replaced with step 203': detect the capacitive touch screen and obtain the detection value of the touch node of the capacitive touch screen.

[0085] Step 204 is replac...

Abstract

The invention discloses an electronic device and a detection method for a capacitive touch screen of the electronic device. The detection method includes the steps that reference data of the capacitive touch screen are stored in the electronic device; the capacitive touch screen is detected, and detection data are obtained; the detection data are compared with the reference data, the capacitive touch screen passes detection if the difference value between the detection data and the reference data does not exceed the difference value range, and the capacitive touch screen does not pass detection if the difference value between the detection data and the reference data exceeds the difference value range. The electronic device and the detection method overcome the defects that in the prior art, when the capacitive touch screen is assembled in a whole machine, problems can hardly be detected through traditional manual clicking and line drawing modes, whether problems happen to the capacitive touch screen or not can be detected even when the capacitive touch screen has been assembled on the electronic device, for example, whether the capacitive touch screen is damaged or nor and whether the capacitive touch screen is flexible or not, and the electronic device and the detection method have the advantages of being convenient to operate and high in work efficiency.

Description

technical field [0001] The invention relates to the field of touch screen detection, in particular to an electronic device and a detection method for a capacitive touch screen. Background technique [0002] At present, consumer intelligent electronic devices are generally equipped with capacitive touch screens to enhance the human-computer interaction experience and realize more applications. As a component, the capacitive touch screen is usually tested separately before being assembled into a complete machine (that is, a complete electronic device), and a simple test is performed after being assembled into a complete machine. After being assembled into a complete machine, the traditional method of testing the function of the touch screen mainly confirms whether the function of the capacitive touch screen is normal by manually clicking and drawing lines on the touch screen (or including buttons) after starting the machine. Because clicking and drawing lines cannot be confir...
