Embodiment Construction

[0016] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] An embodiment of the present invention provides a method for preparing a single-layer multi-touch screen, comprising the following steps:

[0018] S01. Provide an ITO material, and perform exposure, development, and etching on the ITO material to form an ITO film with a sensing line and a driving line, wherein the line width of the sensing line is uniform and is 35-55 μm, and the The induction circuit only exits from the upper end of the ITO film through the ITO wiring;

[0019] S02. Printing silver glue traces on the ITO film, so that the driving circuit passes through the silver g...

Abstract

The invention provides a single-layer multi-touch screen and a manufacturing method thereof. The manufacturing method of the single-layer multi-touch screen comprises the following steps: providing an ITO (Indium Tin Oxide) material, and exposing, developing and etching the ITO material to form an ITO membrane provided with an induction circuit and a driving circuit, wherein the line width of the induction circuit is uniform, and is 35-55[mu]m, and the induction circuit is only led out from an upper end of the ITO membrane through ITO routing; printing silver colloid on the ITO membrane to form silver colloid routing in order that the driving circuit is led out from the upper end and a lower end of the ITO membrane respectively through the silver colloid routing to form an ITO film; and performing processing of printed circuit insulation, OCA (Optical Clear Adhesive) lamination, FPC (Flexible Printed Circuit) binding and panel lamination on the ITO film in sequence to obtain the single-layer multi-touch screen.

Description

technical field [0001] The invention belongs to the technical field of touch screens, in particular to a single-layer multi-point touch screen and a preparation method thereof. Background technique [0002] In the single-layer multi-point structure touch screen, since in the existing ITO lines, the sensing line TX and the driving line need to appear from the upper and lower ends of the screen, therefore, in order to prevent any contact between the lines and facilitate the connection between the ITO line and the silver For the wiring of glue traces, jump point insulation needs to be set on the lower half of the screen. At present, the touch screen that is widely used adopts the single-layer multi-point design of insulating jumpers in the non-visible area, that is, the use of block insulation to carry out the silver glue jumper wiring in the non-visible area. Specifically: the design is divided into two parts: the upper and lower screens. The half-screen directly uses silver ...
