Embodiment 1

[0022] like figure 2 As shown, it is a schematic flowchart of the method for realizing adaptive touch detection on a touch screen described in Embodiment 1 of the present invention, and the method includes the following steps:

[0023] Step 101: Determine the display window of the terminal to be optimized, and extract at least one touchable icon in the display window to be optimized, wherein, when the number of extracted touchable icons is greater than one, any two extracted The distance between touchable icons is not less than the set first threshold.

[0024] Specifically, in this step 101, it is necessary to determine the display window to be optimized of the terminal according to the functions to be realized by the terminal (such as a mobile phone with a touch screen function, a smart phone, a tablet computer, etc.), and according to the determined display window to be optimized, Extract the icon that can be touched in the display window to be optimized (such as the menu...

Embodiment 2

[0046] like image 3 As shown, it is a schematic structural diagram of the device for realizing the adaptive touch detection of the touch screen described in Embodiment 2 of the present invention. The device can be an independent device or integrated in a terminal (such as a mobile phone, a smart phone, a tablet computer with a touch screen function and other terminals), which is not limited in this embodiment of the present invention. The device includes an extraction module 11, an activation module 12, and an execution module 13, wherein:

[0047] The extracting module 11 is configured to determine a display window to be optimized of the terminal, and extract at least one touchable icon in the display window to be optimized, wherein, when the number of extracted touchable icons is greater than one, the The distance between any two extracted touchable icons is not less than the set first threshold; specifically, the number of touchable icons extracted by the extraction module...

Abstract

The invention discloses a method and a device for achieving self-adaptive touch detection of a touch screen. The method includes: extracting at least one touch-executable icon in a display window to be optimized, wherein the distance between any two touch-executable icons is larger than or equal to a set first threshold value, and respectively activating the touch points, wherein the distance between each touch point and each extracted touch-executable icon is smaller than a set second threshold value; and when the situation that at least one touch point is touched in the display window to be optimized is monitored, and the existence of the touch point is confirmed, wherein the shortest distance between the touch point and each extracted touch-executable icon is smaller than the set second threshold value, executing the operation corresponding to the touch-executable icon, wherein the distance between the touch-executable icon and each existence-confirmed touched touch points is shortest. Due to the scheme, on the premise that partial touch points can be activated, multi-touch is achieved, and the effect that computational complexity of the touch screen is reduced can be achieved.

Description

technical field [0001] The invention relates to the technical field of touch screens, in particular to a method and device for realizing adaptive touch detection of a touch screen. Background technique [0002] With the rapid development of display technology, touch screens have gradually spread in people's lives. Currently, touch screens can be classified into resistive, capacitive, infrared and surface acoustic wave types according to their working principles. Among them, the capacitive touch screen is sought after by the industry as a new favorite due to its unique touch principle, high sensitivity, long life, high light transmittance and other advantages. [0003] Currently, common capacitive touch screens can be divided into two types: self-capacitive touch screens and mutual-capacitive touch screens. Wherein, the self-capacitance touch screen is formed by using ITO (Indium Tin Oxides, indium tin metal oxide) on the glass surface to make two layers of horizontal and v...
