no. 1 approach

[0069] A first embodiment of the present invention provides a touch panel, which includes a substrate, a first conductive layer, an insulating layer, and a second conductive layer.

[0070] Figure 1A It is a schematic top view showing the first conductive layer 120 of this embodiment. Figure 1B to show along Figure 1A The schematic cross-sectional view of the line segment 1B-1B'. The first conductive layer 120 is disposed on the substrate 110 . The substrate 110 may be a glass substrate, a quartz substrate or a plastic substrate. The first conductive layer 120 can be made of transparent conductive material or metal. The transparent conductive material is, for example, indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnOx), indium gallium zinc oxide (IGZO), gallium zinc oxide (GZO), or a combination thereof. Metals such as molybdenum (Mo), chromium (Cr), neodymium (Nd), titanium (Ti), copper (Cu), silver (Ag), gold (Au), zinc (Zn), indium (In), gallium ( Ga),...

Abstract

The invention provides touch panel comprises a substrate, a first conductive layer, a second conductive layer, and an insulation layer. The first conductive layer is disposed on the substrate, and the first conductive layer comprises a bridging line and a patterning static protective layer, which are separated from each other. The patterning static protective layer is provided with a floating potential or a grounding potential. The second conductive layer is disposed on the first conductive layer, and comprises a first sensing string and at least two sensing pads disposed on two opposite sides of the first sensing string. The insulation layer is disposed between the first conductive layer and the second conductive layer in a clamped manner. The insulation layer is provided with two contact holes. The bridging line is respectively connected with the adjacent two sensing pads to form a second sensing string. The invention also provides a touch control panel comprising the above mentioned touch panel and the display module.

Description

technical field [0001] The invention relates to a touch panel and a touch display panel. Background technique [0002] In recent years, touch technology has been widely used in various multimedia electronic products, especially portable mobile products, such as mobile phones, e-books, and tablet computers. Using touch technology as an input means can effectively replace the existing keyboard or mouse input means. In addition to convenience, touch input technology has become a very popular way of man-machine interface and multimedia interaction due to its intuitive operation. [0003] Generally speaking, during the manufacturing process of the touch panel, when the electrostatic discharge phenomenon occurs, the components in the touch panel may be damaged, resulting in a decrease in the yield of the manufacturing process. Since the phenomenon of electrostatic discharge cannot be completely avoided in the manufacturing process and in the process of use, how to make a touch p...
