Embodiment 1

[0065] The invention relates to an anti-mistouch method for a touch screen, which can be used in computer terminals with large screens such as tablet computers. The anti-mistouch method of the present invention mainly solves the problem of mistouching the touch screen with the palm of the user when using the stylus to write or draw. When people use a stylus to operate instructions on the touch screen, the side of the hand holding the pen is often supported by the touch screen, so that it is more comfortable and smooth when using the stylus to write or draw. Contact with the touch screen will cause misoperation of the touch screen, thereby affecting the normal command operation of the stylus on the touch screen. The anti-mistouch method of the touch screen can be realized separately or jointly by the touch screen driver layer software and hardware of the computer terminal, the system layer software and the application layer software, such as figure 1 and Figure 13 As shown, ...

Embodiment 2

[0088]The invention relates to an anti-mistouch method for a touch screen, which can be used in computer terminals with large screens such as tablet computers. The anti-mistouch method of the present invention mainly solves the problem of mistouching the touch screen with the palm of the user when using the stylus to write or draw. When people use a stylus to operate instructions on the touch screen, the side of the hand holding the pen is often supported by the touch screen, so that it is more comfortable and smooth when using the stylus to write or draw. Contact with the touch screen will cause misoperation of the touch screen, thereby affecting the normal command operation of the stylus on the touch screen. The anti-mistouch method of the touch screen is physically isolated by the isolation board, which can isolate the signal transmission between the palm or finger and the touch screen. Such as Figure 9 As shown, the separating plate 8 is a transparent or translucent pla...

The anti-mistouch method of the touch screen is physically isolated by the isolation board. Such as Figure 10 As shown, the isolation plate 8 is a transparent or translucent plastic plate; the plastic plate is light in weight, easy to carry, and low in cost. Users c...

Abstract

A mistaken touch prevention method for a touch screen comprises the following steps: (1) forming a mistaken touch area on the touch screen; (2) detecting touch point changes once happening on the touch screen; (3) determining whether touch points are mistaken touch points or not according to the size and the position of the mistaken touch area and the position of the touch points; (4) adjusting the position of the mistaken touch area along with the positions of all of the mistaken touch points; and (5) isolating touch of all of the mistaken touch points. The mistaken touch area can be realized by virtue of software or hardware, and a mistaken touch prevention area in the method can move according to the movement of a palm, namely the movement of the mistaken touch points, and therefore, the mistaken touch points generated by a human hand can be isolated reliably by virtue of automatic adaptation.

Description

technical field [0001] The invention relates to an anti-mis-touch technology of a touch screen, in particular to a method and system for preventing a mis-touch when a user operates on the touch screen with a stylus. Background technique [0002] The current anti-mistouch method is usually aimed at the mistouch operation on the edge of the touch screen when holding a mobile terminal with a touch screen. Such as: [0003] A false touch prevention system with the publication number 103902074A is applied to an electronic device, the electronic device includes a display screen, and the system includes: a setting module for determining the designation of the false touch prevention on the display screen Area; judging module, used to determine whether the touch event is single-touch or multi-touch when a touch event occurs in the specified area; response module, used to determine when the touch event is multi-touch , ignoring the touch points that occur in the specified area, and ...
