Problems solved by technology

The patterning of the ITO conductive layer requires an etching process, and a large amount of ITO materials will be wasted. In addition, indium element is a rare earth metal with very little stock in nature. In recent years, the cost of indium element materials has risen sharply. In terms of material costs In the case where upgrading inevitably produces material waste, it will inevitably lead to an increase in preparation costs
Moreover, if it is necessary to achieve low square resistance, the ITO conductive layer must be thicker, which will not only further increase the preparation cost, but also reduce the transmittance
In addition, the ITO conductive layer is easy to crack, making the performance of the touch screen less stable

Abstract

A touch panel includes: a glass cover plate including a display area and a non-display area located at an outer edge of the display area; and a touch sensing module laminated on the glass cover plate. The touch sensing module includes a first conductive layer and a second conductive layer. The first conductive layer includes a plurality of first conductive strips; the second conductive layer includes a plurality of second conductive strips. The touch sensing module includes a sensing area defined by edges of the first conductive layer and the second conductive layer. The sensing area includes a visual area and a non-visual area located at an outer edge of the visual area. A projection of the visual area on the glass cover plate coincides with the display area, a projection of the non-visual area on the glass cover plate falls within the non-display area.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch panel and a touch display device including the touch panel. Background technique [0002] Currently, there are more and more electronic devices using touch screens, such as mobile phones, tablet computers, MP4 players, and e-books. A touch screen is an inductive device that can receive input signals such as touch. The touch screen has endowed information interaction with a new look and is a very attractive new information interaction device. The development of touch screen technology has aroused widespread concern in the information media circles at home and abroad, and has become a rising high-tech industry in the optoelectronic industry. However, most of the existing touch screens are plug-in or embedded in the display screen of the electronic device. The sensing area of ​​the touch screen is directly opposite to the display screen, so that the user's touch ope...
