Problems solved by technology

This method has the following two problems: on the one hand, the laminating technology of the film layers seems easy, but due to the difference in the stress accumulation of the upper and lower layers in the mass production process, it is easy to twist or warp; The introduction of the substrate also leads to an increase in the overall thickness of the touch screen

Abstract

A touch panel includes an insulative substrate, a first adhesive layer, a first transparent conductive layer, a second adhesive layer, a second transparent conductive layer, a number of first electrodes, a first conductive trace, a number of second electrode, and a second conductive trace. The insulative substrate, the first adhesive layer, the first transparent conductive layer, the second adhesive layer, and the second transparent conductive layer are stacked with each other in that order. The first transparent conductive layer and the second transparent conductive layer are electrically insulated from each other only by the second adhesive layer. A method for making the touch panel is also related.

Description

technical field [0001] The invention relates to a touch screen and a preparation method thereof, in particular to a capacitive touch screen and a preparation method thereof. Background technique [0002] In recent years, along with the high performance and diversification of various electronic devices such as mobile phones and touch navigation systems, the number of electronic devices in which a light-transmitting touch panel is mounted on the front of a display device such as a liquid crystal is increasing. A user of such an electronic device performs operations by pressing the touch panel with a finger or a pen while visually confirming display contents of a display device located behind the touch panel through the touch panel. Thereby, various functions of the electronic device can be operated. [0003] According to different working principles and transmission media of touch screens, existing touch screens are divided into four types, namely resistive type, capacitive t...
