Embodiment Construction

[0052] The above-mentioned purpose of the present invention and its structural and functional characteristics will be described according to the preferred embodiments of the attached drawings.

[0053] see image 3 and Figure 4 As shown, it is a schematic diagram of the implementation of a preferred embodiment of the present invention. The light-transmitting touch panel 30 of the present invention includes a first light-transmitting substrate 40, a second light-transmitting substrate 50 and a bonding layer 60. The first light-transmitting The substrate 40 is a glass substrate or a PMMA (acrylic) substrate, and one side of the first transparent substrate 40 has a first surface 41 on which a plurality of first induction conductors 411 are covered. An inductive conductor 411 is electrically connected to each other along a first direction (horizontal direction) to form a plurality of first conductor groups 412, at least one end of each first conductor group 412 is connected to a f...

Abstract

The present invention provides a transparent touch pad and a method for manufacturing the same. The transparent touch pad includes a first transparent substrate, a second transparent substrate and an adhesion layer. The adhesion sides of the first transparent substrate and the second transparent substrate are respectively provided with a plurality of first sensing conductors and second sensing conductors and are adhered by the adhesion layer to form a transparent touch pad having two-dimensional arrangement of sensing conductors. Since the first transparent substrate has a low electrical resistance and the second transparent substrate is easy to process, the area of a visible region of the touch pad is increased and a lithographic process is no longer required. In this way, the structure of the touch pad is simplified and the production cost is reduced.

Description

technical field [0001] The invention relates to a light-transmitting touch panel, in particular to a light-transmitting touch panel structure and a manufacturing method thereof which can simplify the structure and reduce the manufacturing cost, increase the visible area and improve the yield rate. Background technique [0002] Today's touch panels are mainly divided into four types based on their sensing principles: resistive, capacitive, acoustic, and optical. Among them, the structure of capacitive touch panels has the characteristics of dustproof, fireproof, and high resolution, so it is widely used. The working principle of the capacitive touch panel is mainly to confirm the position of the contact point based on the change of capacitance, and to use the proximity of the touch object (such as a conductor such as a finger) to generate a capacitive electrical change between the sensing conductors, while Determine the coordinates of the contact point. [0003] There are ma...
