Touch screen button area processing method and device

technical field

The present invention relates to the technical field of touch screens, in particular to a method and device for processing key areas of a touch screen.

Background technique

Touch screen, also known as touch panel, is an inductive display device that can receive input signals such as contacts. When touching the touch buttons on the screen, the tactile feedback system on the screen can drive various connected devices according to pre-programmed programs. It can be used to replace the mechanical button panel, and to produce vivid audio-visual effects through the liquid crystal display screen; because of its technical convenience, it is widely used in various technical fields such as mobile phones and computers.

The existing method for processing the button area of the touch screen needs to set the positioning range values of all the touch buttons in advance. The specific processing method includes the following steps:

1) The user starts to operate the button area of the touch screen;

2) Capture the coordinates of the center point of the area pressed by the user;

3) Judging that the coordinates of the center point of the user's pressing area fall into the positioning range value of the touch button, and highlighting the corresponding touch key corresponding to the positioning range value in which the user's pressing area center point falls;

4) Capture the touch action and judge whether to turn the page;

5) When it is judged as a page-turning operation, process the page-turning action; when it is judged as a non-page-turning operation, then enter the function menu of the touch button corresponding to the positioning range value that the center point of the user presses the area falls into.

In the process of realizing the above-mentioned method for processing the button area of the touch screen, the inventor found that at least the following problems existed in the prior art:

In step 3), coordinate system positioning is generally used to program the coordinate positioning range value of each touch button, and the positioning range that the user presses the center point coordinates of the area falls into is highlighted. In this step, each pre-positioned The range of each touch button is relatively small, so it often occurs that the user presses an area that does not belong to any positioning range. At this time, the screen does not respond, and the icon menu that the user wants to enter cannot be correctly judged.
