Problems solved by technology

[0012] However, the existing touch display device adopts two transparent conductive layers, the thickness of the touch display device is still relatively large, the light transmission performance is poor, and the integration degree of the touch display device is still low.
In the U.S. Patent No. US20070291009, an ITO layer and a metal layer are used as the two conductive layers of the touch screen, but the above problems still cannot be solved

Embodiment Construction

[0057] The inventors found that the existing touch screen of the embedded capacitive touch display device includes a touch layer made of transparent metal and a metal layer for bridging the touch layer, and the entire display device is relatively thick. Therefore, the inventor creatively uses part of the structure of the display device to bridge the touch layer, which reduces the thickness of the touch display module, realizes the integration of touch display, and reduces the number of reticles.

[0058] The touch display device of the present invention includes a touch device and a display device, the display device includes a liquid crystal display panel, and the touch device is integrated inside the liquid crystal display panel. The above definitions apply throughout the text and are hereby clarified.

[0059] The technical solutions of the present invention will be described in detail below in conjunction with specific embodiments of the present invention.

Abstract

The invention provides a touch displaying device. The touch display device comprises a touch screen configured on a substrate, wherein the touch screen is integrated in the displaying device, the common part of the touch screen and the displaying device is used as an electrically conductive structure. Since a metal layer is omitted, the touch displaying device has small thickness and good light transmittance.

Description

technical field [0001] The invention relates to a liquid crystal display panel, in particular to a liquid crystal display panel with a touch function. Background technique [0002] The touch screen can be used as an interface tool for operating electronic devices through the display screen, allowing users to input information directly on the surface of the display device with a touch screen by touching or handwriting, which is more friendly and convenient than input devices such as mice and keyboards. Therefore, it is more and more widely used in various portable devices. [0003] According to the type of contact used (such as fingers, pens, etc.) and the way of confirmation point (the position where the contact operates the touch screen), the touch screen can be divided into resistive, capacitive, surface acoustic wave, infrared, etc. . Currently, resistive and capacitive touch screen technologies are widely used. [0004] As an interface for operation, the existing touc...
