Embodiment Construction

[0039] In order to make the technical solution of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] see figure 1 , as a specific embodiment of the touch screen 100 of the present invention, it includes a driving signal input wire 110 , a sensing signal output wire 120 and a plurality of electrodes 130 . Wherein, each electrode 130 is arranged at the display area of ​​the touch screen 100 , and a plurality of electrodes 130 are arranged in a matrix. Meanwhile, the shapes and sizes of the plurality of electrodes 130 disposed at the display area of ​​the touch screen 100 are not exactly the same. Therefore, the inductive capacitances generated by the electrodes 130 with different shapes and sizes are also different when touched.

[0041] Furthermore, two wires are provided on the touch screen 100 , namely: a driving signal input wire 110 and a sensing si...

Abstract

The invention discloses a touch screen, a touch position locating method and a display device. The touch screen comprises a drive signal input wire, an induction signal output wire and a plurality of electrodes. The electrodes are arranged in a display area of the touch screen, are arranged in a determinant mode and are not completely identical in shape and size. Every two adjacent electrodes in each line are electrically connected. One end of the drive signal input wire is electrically connected with any one electrode in each line, and the other end of the drive signal input wire is electrically connected with the output end of a locating detection device. One end of the induction signal output wire is electrically connected with any one electrode except the electrodes electrically connected with the drive signal input wire in each line, and the other end of the induction signal output wire is connected with the input end of the locating detection device. Excessive wiring is not needed, and the board width of the touch screen is effectively reduced; finally, the problem that a traditional touch screen is not beneficial for achieving narrow-side design is effectively solved.

Description

technical field [0001] The present invention relates to the field of touch control, in particular to a touch screen, a touch position positioning method and a display device. Background technique [0002] With the rapid development of display technology, touch screen panels (Touch Screen Panels) have gradually spread in people's lives. At present, the traditional touch screen locates the touch position through the design based on the rows and columns of the touch screen. That is, by arranging mutually independent wires between the rows and columns of the touch screen, arranging the wires around the touch screen and then connecting them to the monitoring chip, the positioning of the touch position is realized. Therefore, when positioning the touch position by arranging many wires around the touch screen, the frame of the touch screen must have a certain width. This is not conducive to realizing the narrow frame design of the touch screen. Contents of the invention [000...
