Problems solved by technology

[0005] The inventor found in the process of implementing the present invention that the defect of the existing capacitive screen solution is that no corresponding fault-tolerant mechanism is set for each button on the capacitive screen, so that the click hit rate of the buttons is low. The reasons are as follows:
The visible area corresponding to the button on the existing capacitive screen is the pressing area, and its range is relatively small. Therefore, when the user presses the button on the capacitive screen, the contact point when pressing may be different from the button on the capacitive screen. Large deviations occur in the visible area, such as: figure 1 Among them, the visible area of ​​the "Back" button is small. When the user presses it, the contact point may be located outside the pressed area of ​​the "Back" button (that is, the visible area 1), resulting in The pressing of the "Back" button failed;
[0007] 2. The visible area of ​​the button on the existing capacitive screen is the response area, and its range is relatively small. When the user presses a button, the finger may move on the capacitive screen, for example: figure 1 In , after the finger presses the "Back" button, it moves on the capacitive screen, so that the contact point of the finger when it is lifted is offset from the response area of ​​the "Back" button (that is, the visible area 1), causing the "Back" button Failed to press the "Back" button

Abstract

The embodiment of the invention discloses a key area setting method of a capacitive screen, which comprises the following steps: according to the preset press parameters, extending outwards along the edge of the visual area of each key on the capacitive screen to form an area, and setting the extended area as the press response area of each key; and according to the preset response parameters, extending outwards along the edge of the press response area of each key on the capacitive screen to form an area, and setting the extended area as the motion lift response area of each key. The embodiment of the invention also discloses a terminal. The invention can be used for optimizing the key area of the prior capacitive screen and setting the corresponding fault-tolerant mechanism, thereby enhancing the hit rate of the press operation on the keys and enhancing the touch experience of users.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a method for setting a key area of ​​a capacitive screen and a terminal. Background technique [0002] Capacitive touch screen, also known as capacitive touch screen, is mainly a layer of transparent special metal conductive substance on the glass surface. When a finger or other organism touches the metal layer, the capacitance of the contact will change. Through its capacitance value Changes in the touch position are determined to obtain touch information. Specifically, when a press operation is performed on the capacitive screen, the point with the largest capacitance value on the capacitive screen is the contact point of the press operation. [0003] The capacitive screen is a surface-contact touch screen, which is generally operated by fingers and is more sensitive than ordinary resistive screens. Each key on the capacitive screen has two areas, one of which is: the pr...
