Problems solved by technology

[0004] Generally speaking, most flexible substrate materials cannot withstand high temperatures (about 300°C). However, most of the current conductive adhesives are thermosetting conductive adhesives, and thermosetting conductive adhesives require high temperature treatment to It is sintered and hardened. Therefore, when a thermosetting conductive adhesive is applied to a flexible substrate material, the long-term high-temperature hardening process in order to harden the conductive adhesive will not only cause damage to the flexible substrate material, but also cause consumption. able problem
Also, if a lower temperature is used for the hardening process, the conductive material in the conductive adhesive will not be effectively combined due to insufficient sintering temperature, resulting in poor conductive properties of the conductive adhesive

Embodiment Construction

[0028] A photosensitive hardening conductive adhesive for a touch panel according to a preferred embodiment of the present invention will be described below.

[0029] Please refer to Figure 1A to Figure 1D , and combined with the following description to understand the manufacturing process of the touch panel using the photosensitive hardening conductive adhesive of the present invention.

[0030] First of all, the photosensitive hardening conductive adhesive described in the present invention is used in touch panels, especially suitable for touch panels using soft substrates (or called flexible substrates), so as to achieve ultra-thin touch panels and flexibility. Wherein, the flexible substrate is, for example, flexible glass, a plastic plate or a plastic film, and the plastic material may specifically be polyethylene terephthalate (PET).

[0031] Such as Figure 1A As shown, in practice, a plurality of conductive patterns 11 are formed on the touch area A on the flexible...

Abstract

A photo-curing conductive adhesive for a touch panel includes an adhesive in an amount within the range of 20 to 30 wt % and the metal particle composition in an amount within the range of 70 to 80 wt %.

Description

technical field [0001] The present invention relates to a conductive adhesive, in particular to a photosensitive hardening conductive adhesive for a touch panel. Background technique [0002] With the rapid development of the electronics industry, various types of touch input technologies have been widely used in electronic products, such as mobile phones and tablet computers, which use touch panels as input interfaces, and users can conveniently touch the surface of the input panel directly with their hands To issue instructions, or to operate the mouse or to input handwritten text by moving around the surface of the touch panel. The display panel matched with the touch panel can also display virtual buttons for the user to click, and the user can input corresponding relevant text through these virtual buttons. [0003] In order to make electronic products have the characteristics of easy turning, light weight and thin thickness, flexible substrate materials (or flexible s...
