Abstract

The invention provides a method for resisting coupling interference in a resistive touch screen and a resistive touch screen. The method comprises the following steps: carrying out reversal processing on a driving signal of an LCD (liquid crystal display) to generate a reverse driving signal; and inputting the reverse driving signal into a resistive touch screen circuit to generate a reverse interference signal so as to eliminate a coupling interference signal generated by the driving signal. The resistive touch screen comprises a transparent substrate, a first conducting film layer, a transparent surface layer, a second conducting film layer, transparent isolation points positioned between the first conducting film layer and the second conducting film layer, a generating module for generating an interference signal reversed to the coupling interference signal, and an import module. By using the method for resisting coupling interference in a resistive touch screen and the resistive touch screen provided by the invention, the coupling interference of an interference source to the resistive touch screen is eliminated, and the probability of misoperation of the touch screen is reduced.

Description

technical field [0001] Embodiments of the present invention relate to a resistive touch screen, in particular to a method for anti-coupling interference in the resistive touch screen and the resistive touch screen. Background technique [0002] A resistive touch screen is a device that touches it with a finger or a pen to write, draw, or instruct a device (such as a computer) to execute commands by making icons, and is usually attached to a display device such as a liquid crystal display (Liquid Crystal Display; referred to as: LCD). [0003] figure 1 It is a structural schematic diagram of an existing resistive touch screen, such as figure 1 As shown, the resistive touch screen includes: a transparent glass substrate 11, a conductive layer 12 covered on the glass substrate 11, a transparent surface layer 13 located on the top, a conductive layer 14 coated on the inner surface of the transparent surface layer 13, double-sided adhesive tape 16, And transparent isolation po...
