Problems solved by technology

However, when writing, the pen may leave the touch screen for a short time, making the system mistakenly think that it has returned to the hand detection mode, and misreport the position of the palm, resulting in writing errors
[0007] This shows that above-mentioned prior art obviously has inconvenience and defective, and extremely waits to be further improved
In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure and method for general products and methods to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve

Abstract

The present invention provides a detection device and method of a touch screen. The detection device of the touch screen includes a touch screen, a controller and a memory. The position does not provide the position of all objects within the preset range, such as the position of the palm. And, unless the pen is no longer detected beyond the preset time, the positions of objects other than the pen within the preset range are provided again.

Description

technical field [0001] The invention relates to a capacitive writing device, in particular to a detection device and method for a touch screen. Background technique [0002] A known mutual capacitive sensor includes an insulating surface layer, a first conductive layer, a dielectric layer, and a second conductive layer, wherein the first conductive layer and the second conductive layer respectively have a plurality of first conductive layers. A conductive strip and a second conductive strip, these conductive strips may be composed of a plurality of conductive sheets and connecting lines of the conductive sheets connected in series. [0003] When performing mutual capacitance detection, one of the first conductive layer and the second conductive layer is driven, and the other of the first conductive layer and the second conductive layer is detected. For example, the driving signal is provided to each first conductive strip one by one, and corresponding to each first conducti...
