Problems solved by technology

Touchscreen controls are susceptible to interference from various noise sources when in operation
In some extreme cases, when the noise is too large, most of the sampled values ​​will have large deviations, and touch control based on the sampled values ​​with large deviations will cause the problem of "ghost points"

Abstract

The invention relates to a touch data processing method, which comprises the following steps of: acquiring an induction value of each induction area on a touch screen, with the induction area comprising a touchable area and a non-touchable area; if the induction value of the preset number / proportion of the induction areas is larger than a noise threshold value, carrying out first suppression on the induction value in the non-touchable area, carrying out second suppression on the induction value of the touchable area, wherein the first suppression processing is different from the second suppression processing. The touch area and the non-touch area in the touch screen are distinguished, and after it is judged that each sensing area reaches the set data fluctuation, differential suppression processing is carried out on the touch area and the non-touch area, so that touch event information of the touchable area can be reserved while information of the non-touch area is eliminated.

Description

technical field [0001] The present invention relates to the technical field of touch screens, in particular to a touch data processing method, device and touch screen. Background technique [0002] Touch screens are widely used in portable devices, such as mobile phones, tablet computers and so on. When the touch screen control device is working, it is susceptible to interference from various noise sources. In some extreme cases, when the noise is too large, most of the sampling values ​​will have large deviations, and touch control based on sampling values ​​with large deviations will cause the problem of "ghost points". Contents of the invention [0003] Based on this, it is necessary to provide a touch data processing method, device and touch screen for the above technical problems. [0004] A touch data processing method, the method comprising: [0005] Obtain the sensing value of each sensing area on the touch screen, where the sensing area includes a touchable are...
