Problems solved by technology
For example, the touch screen failure problem that often affects the user experience effect, that is, the ghost hand problem
[0003] At present, the problem of ghost points caused by touch screen noise is generally solved by increasing the reporting threshold and related filtering algorithms, but at the same time, there are also problems such as false filtering and excessive thresholds, which cause users to use the touch screen ineffectively.

Embodiment Construction
[0065] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the illustrative examples below are not intended to represent all implementations consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with some aspects of the invention as recited in the appended claims.
[0066] At present, the ghost point problem caused by touch screen noise is generally solved by raising the reporting threshold and related filtering algorithms, but at the same time, there are also problems such as false filtering and high threshold, which cause users to use the touch screen ineffectively. For the method of raising the reporting point threshold to avoid ghost points, when the user ope...

The invention relates to a method and device for determining a touch screen position on a touch screen and a medium. The method comprises the following steps: acquiring feature data generated by a touch screen operation on the touch screen position; obtaining noise data on the touch screen; multiplying the feature data and the noise data by a set factor, wherein the set factor is greater than or equal to 1; determining the position of the touch screen based on the feature data multiplied by the set factor and the noise data multiplied by the set factor. By adopting the method, the induction signal and the interference signal can be accurately distinguished, and the ghost point problem caused by interference in each scene can be solved through subsequent filtering and other algorithms.
Description
technical field [0001] The present disclosure relates to the technical field of touch screens, and in particular, to a method, device, and medium for determining a position of a touch screen on a touch screen. Background technique [0002] With the widespread use of electronic products, touch screens are also used in many electronic products. Almost as long as there is a display screen, it is inseparable from the touch screen, especially the mobile phone that everyone must have now. The widespread use of touchscreens brings many problems along with them. In addition to hardware failures, environmental factors are also unavoidable, resulting in poor user experience. For example, at present, the problem of touch screen failure, which often affects the user experience effect, is the ghost hand problem. [0003] At present, the ghost point problem caused by touch screen noise is generally solved by raising the reporting threshold and related filtering algorithms, but at the s...
