Specific embodiment

The characteristics of in order to more fully hereinafter understand the embodiment of the present invention and technology contents, with reference to the accompanying drawing to this hair The realization of bright embodiment is described in detail, appended attached drawing purposes of discussion only for reference, is not used to limit the embodiment of the present invention.

Fig. 1 is the flow diagram of the information processing method of the embodiment of the present invention one, the information processing method in this example Applied in electronic equipment, the electronic equipment includes capacitive touch screen, the capacitive touch screen have N row electrode and M column electrode, N, M >=2；As shown in Figure 1, the information processing method the following steps are included:

Step 101: using the scanning signal of first frequency to the N row electrode and M column electrode of the capacitive touch screen It is scanned one by one, obtains scanning result.

In the embodiment of the present invention, the electronic equipment can be the electronic equipments such as mobile phone, pad, all-in-one machine；This electron-like is set It is standby that there is capacitive touch screen；Capacitive touch screen is worked using the electric current induction of human body, specifically, when finger touches When on metal layer, due to human body electric field, user and touch screen surface are formed with a coupled capacitor, for high-frequency current, Capacitor is direct conductor, and then finger siphons away the electric current of a very little from contact point.

Based on this, the scanning signal of first frequency is generated first with the signal generation module in electronic equipment, here, the One frequency namely fixed frequency.Then, the scanning signal of first frequency is sent to one by one by the transmitting terminal of AFE(analog front end) described The N row electrode of capacitive touch screen and the receiving end of M column electrode；When user touches capacitive touch screen, in capacitive touch Electric current releasing will be had by touching the electrode at a certain position of screen, and import human body；Therefore, the scanning signal of first frequency is through the position When setting the electrode at place, signal will change, and the signal of variation is transmitted to the transmitting terminal of electrode；By connecing for AFE(analog front end) Receiving end receives the consequential signal that the transmitting terminal of the N row electrode and M column electrode is launched one by one, obtains scanning result.

Step 102: according to the scanning result, judging whether touch operation occurs on the capacitive touch screen.

Then, the scanning signal of first frequency is sent to the capacitive touch screen one by one by the transmitting terminal of AFE(analog front end) N row electrode and M column electrode receiving end；When user touches capacitive touch screen, in a certain position of capacitive touch screen The electrode at the place of setting will have electric current releasing, and import human body.

Step 203: receiving the consequential signal that the transmitting terminal of the N row electrode and M column electrode is launched, one by one to obtain Scanning result.

Therefore, when the scanning signal of first frequency is through electrode at the position, signal will change, and by variation Signal is transmitted to the transmitting terminal of electrode；Receive the transmission of the N row electrode and M column electrode one by one by the receiving end of AFE(analog front end) The consequential signal launched is held, scanning result is obtained.

Step 204: according to the scanning result, obtaining the change amount signal of the scanning signal Yu the consequential signal.

Step 205: judging whether the change amount signal is more than or equal to preset threshold value.

Step 206: when the change amount signal is more than or equal to the threshold value, determining and occur on the capacitive touch screen Touch operation.

In the embodiment of the present invention, according to the scanning result, the letter of each scanning signal Yu the consequential signal is determined Number variable quantity.Change amount signal is more than or equal at the electrode of preset threshold value, there is touch operation.

Step 207: when touch operation occurs for the capacitive touch screen, being based on the scanning result, determine to be greater than Electrode line number and columns corresponding to change amount signal equal to the threshold value.

Step 208: being based on the electrode line number and columns, determine the first position of the touch operation.

Step 209: frequency sweep being carried out to the electrode at the first position using the swept-frequency signal of the first frequency range, obtains frequency sweep As a result.

Step 210: according to the frequency sweep as a result, determining the attribute information of the touch operation.
