Problems solved by technology

[0003] Whether it is an add-on type or a capacitive touch panel on a glass substrate, the bridge structure of the touch element can be divided into a bridge island form or a bridge via form. The bridge structures in various forms are all made of metal materials, causing serious reflection problems in traditional touch panels, resulting in poor display quality
In addition, the traditional bridge structure design will cause its on-resistance to be too large, thus causing the touch panel to be insensitive.

Abstract

A touch display device is provided. The touch display device includes a touch panel disposed on a display panel. The touch panel includes a plurality of first conductive patterns arranged along a first direction, wherein the first conductive patterns are separated from each other. A plurality of second conductive patterns is arranged along a second direction perpendicular to the first direction, wherein the second conductive patterns are connected with each other. An isolation structure is disposed between any two adjacent first conductive patterns. A plurality of conductive bridge structures is disposed on the isolation structure for electrically connecting any two adjacent first conductive patterns.

Description

technical field [0001] The present invention relates to a touch display device, in particular to a structural design of a touch element of a capacitive touch panel. Background technique [0002] The current capacitive touch panel can be divided into two types, one is the add-on touch panel, which adds the touch panel to the outside of the display panel, and the add-on touch panel needs to be composed of two glass substrates. One of the glass substrates is used to make a capacitive touch sensor (touch sensor) on it, and the other glass substrate is used as a protective cover (cover lens) for the capacitive touch sensor. The other is a touch panel on a glass substrate (on glass type), which manufactures a capacitive touch element (touch sensor) on a protective cover (cover lens) of the touch panel, and then connects the touch panel with the display panels combined. [0003] Whether it is an add-on type or a capacitive touch panel on a glass substrate, the bridge structure of...
