Problems solved by technology

[0006] 1) Engineering implementation issues. The first solution needs to modify the current manufacturing process of the touch screen, and it is difficult to integrate it into an ultra-thin mobile phone after adding a layer; the second is to add sensors at the four corners of the touch screen. Not conducive to mobile phone integration
[0007] 2) In terms of cost, both of the above two solutions need to update existing equipment and add parts, which have problems such as high cost and unstable process

[0046] see figure 1 , propose the first embodiment of the touch screen control method of the present invention, the touch screen control method includes the following steps:

[0047] Step S10: When the touch object clicks on the touch screen, detect the capacitance change, and calculate the moving speed of the touch object according to the capacitance change

[0048] The touch object is any object capable of touch operation on the touch screen, usually a user's finger, unless otherwise specified below, the finger refers to the touch object.

[0049] like figure 2 As shown, the touch screen contains two routings, namely Yn and Xm, one of which is a driving signal routing, and the other is a sensing routing, and there are several driving signal routings and sensing routings. The structure of the touch screen used in the present invention is the same as that commonly used in the market, but has a higher resolution, that is, there are more X and Y traces on a touch screen of th...

Abstract

The invention discloses a touch screen control method and a touch screen device. The touch screen control method includes the steps: when a touch object clicks a touch screen, detecting capacitive changes, and calculating moving speed of the touch object according to the capacitive changes; calculating pressure when the touch object clicks the touch screen according to the moving speed; executing corresponding operation according to the pressure. Consequently, detection of speed and pressure when a finger clicks the touch screen can be realized on the basis of an existing capacitive-type touch screen without adding any hardware, simplicity in realization and low cost are realized, a third dimension is provided for man-machine interaction, more plentiful interaction modes are provided for touch equipment, and software on the touch equipment is facilitated to realize more plentiful functions.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a touch screen control method, a touch screen and a device. Background technique [0002] Capacitive touch screens have been widely used in mobile terminals such as mobile phones and tablets, and their convenient operation methods are very popular among users. In the prior art, the control method of the touch screen mainly performs corresponding operations by identifying the position coordinates (X, Y coordinates touched by the finger) of the finger clicking or touching the touch screen. In order to further enrich the control functions of the touch screen, it is proposed in the prior art to change the traditional human-computer interaction from two-dimensional (X, Y coordinates of finger touch) to three-dimensional (X, Y coordinates of finger touch) by further detecting the pressure of the finger on the touch screen in the prior art. The Y coordinate plus the pressure of t...
