AI Technical Summary

Technical Problem

Existing resistive touchscreens are prone to generating false dots during multi-touch, which leads to a decrease in recognition accuracy and makes it difficult to effectively eliminate false dots while achieving high-precision recognition.

Method used

It adopts a magnetic shielding encapsulation structure, including a magnetic field generating board and a touch panel. It utilizes a magnetically sensitive resistive layer and a directional magnetic field to adjust the resistance distribution, and combines an interlocking control circuit to improve the accuracy of touch position recognition.

Benefits of technology

While ensuring high-precision recognition, the generation of false dots is reduced, improving the recognition accuracy of multi-touch. The touch position is verified by adjusting the resistance distribution through a magnetic field, thus enhancing touch accuracy.

Abstract

The application relates to a resistive touch screen and a production method thereof, which comprises a magnetic shielding package, an electromagnetic generating plate and at least two touch plates; a resistive layer of at least one touch plate is configured as a magnetic sensitive resistive layer; the electromagnetic generating plate comprises a plurality of electromagnetic generating units, each electromagnetic generating unit generates a directional magnetic field at a corresponding position when working to adjust the resistance value distribution of the magnetic sensitive resistive layer; according to the touch condition of a first touch point, the resistance distribution condition of the touch plate can be adjusted, so that the touch far from the touch point is more sensitive, and multiple touch points can be accurately recognized; on the premise of ensuring the accuracy, the possibility of generating a touch false point can be reduced; meanwhile, through a touch plate with a variable resistance value distribution and a touch plate with an invariable resistance value distribution, the first touch position can be verified, and the recognition accuracy of the touch position is further improved.
