Problems solved by technology

However, if the overall line width of the bridged metal layer is large, although the RC loading of the sensing electrode can be made smaller and will not affect signal transmission, however, since the metal layer is generally an opaque material, Therefore, the visibility of the touch display device will be affected; in addition, if the overall line width of the bridged metal layer is small, although the visibility of the touch display device will not be affected, the RC load of the sensing electrode will be too much. large enough to affect its signal transmission

Abstract

First touch patterns of a touch display device are disposed on a first substrate, and have bridge units and first electrode portions. The first electrode portions are disposed spaced from each other. The bridge units are connected with adjacent two of the first electrode portions. A second substrate is disposed opposite to the first substrate. A liquid crystal layer is disposed between the first substrate and the second substrate. One of the bridge units has two first portions, a second portion and two third portions. The first portions are located on the first electrode portions, and directly contact with the first electrode portions. The third portions are located on two of the first portions, and the second portion is located between two of the third portions. The first portion has a first width, and the second portion has a second width smaller than the first width.

Description

technical field [0001] The invention relates to a touch display device and a touch substrate. Background technique [0002] With the advancement of technology, touch technology has been widely used in various electronic products. For the touch display device, because the user can perform various functions by touching the display screen of the touch display device, it can simplify the complexity of the user's operation, and is more and more popular among consumers. . [0003] The touch display device generally includes an Out-Cell touch device or an On-Cell touch device. In the aspect of the plug-in touch device, the touch sensing circuit is formed on a substrate, and then combined with the display panel to form a touch display panel. In the aspect of the embedded touch device, the touch sensing circuit is directly formed on the light-transmitting substrate such as the color filter substrate, and combined with the thin film transistor substrate to form a touch display pane...
