Problems solved by technology

However, metal wires have a high reflectivity and have a certain width, so it is easier to see the peripheral lines from the appearance of the touch panel product. The problem that the peripheral lines are visible to the naked eye cannot meet the requirements of a transparent touch panel, resulting in touch Appearance defects of control panel products

Embodiment Construction

[0029] The present invention will be described in further detail below in combination with specific implementation methods and accompanying drawings. The following embodiments only use the capacitive touch panel technology as an example, however, the spirit of the present invention can be extended to other touch panel technologies such as resistive, infrared and surface acoustic wave.

[0030] figure 1 It is a schematic plan view of the touch panel structure of the embodiment of the present invention. The touch panel 50 includes a sensing layer 55 and a plurality of peripheral circuits 60. The sensing layer 55 is used to sense touch actions and generate sensing signals; the plurality of peripheral circuits 60 are distributed in the peripheral region of the sensing layer 55 and connected to the sensing layer 55 for connecting The sensing signal is sent to the controller for calculation, so as to determine the coordinates of the touch position, wherein the plurality of peripher...

Abstract

The invention provides a touch panel structure, which comprises a sensing layer and a plurality of peripheral circuits which are distributed in the peripheral area of the sensing layer and connected to the sensing layer, and the peripheral circuits are made of transparent conductive materials. The invention also provides a touch panel manufacturing method. According to the touch panel structure and the touch panel manufacturing method, the peripheral circuits are made of the transparent conductive materials, and the transparent conductive materials are good in transparency and conductivity, so that the visibility of the peripheral circuits can be reduced while good conductivity is provided, and the requirement of the transparent touch panel is met.

Description

technical field [0001] The present invention relates to touch technology, in particular to a structure and manufacturing method of a touch panel. Background technique [0002] The touch panel has been widely used in work and life. Usually, the touch panel has a sensing area on the surface of a substrate, and the sensing area is used to sense the finger of the human body or a writing tool similar to a pen to achieve the purpose of touch. Touch panels can be classified into resistive, capacitive, infrared, and surface acoustic wave based on their principles. [0003] In a common capacitive touch panel, a plurality of transparent electrodes insulated and intersected with each other are arranged on the surface of the substrate, and the transparent electrodes are connected to the controller through peripheral circuits. When the touch object approaches or touches the touch panel, it will cause a change in the capacitance between the electrodes at the touch position. These capacit...
