Abstract

The invention provides a touch screen, which has a first substrate, a second substrate and a plurality of insulating grooves, the first substrate has a first conductive layer, and extends from both ends of the first conductive layer and has first electrode leads. a plurality of first electrodes; the second substrate has a second conductive layer, and a plurality of second electrodes extending from both ends of the second conductive layer and having second electrode lead-out parts; the insulating trench is arranged on the first Between any one of the electrode lead-out part and the second electrode lead-out part, at least on any one of the first conductive layer and the second conductive layer. According to this configuration, it is possible to obtain a touch panel in which the pitch of the first electrode lead-out portion or the pitch of the second electrode lead-out portion can be narrowed, and stable electrical insulation and connection can be realized.

Description

technical field [0001] The present invention relates to a touch screen used for the operation of various electronic devices. Background technique [0002] In recent years, with the development of high performance and diversification of various electronic equipment such as mobile phones and car navigation systems, electronic equipment in which a light-transmitting touch panel is mounted on the front of a display element such as a liquid crystal is becoming more and more popular. Increase. A user of such an electronic device operates the touch panel by pressing the touch panel with a finger, a pen, or the like while viewing a display on a display element located on the back of the touch panel. Thereby, each function of the electronic device can be switched. Therefore, a touch screen with good visual recognition and reliable operation and electrical connection is required. [0003] use Figure 7 ~ Figure 9 , to describe the existing touch screen. [0004] Figure 7 is a cr...
