technical field

Background technique

The touch panel originated in the 1970s when the U.S. military developed it for military use. It was transferred to civilian use in the 1980s, and then developed into various livelihood uses, such as bank ATMs, station automatic ticket vending machines, and store POS systems (Point of Sale). ), smart phones, car touch panels, etc., because of the advantages of easy operation, they can replace traditional buttons, and have gradually been integrated into various human electronic products, especially in mobile communications, consumer In the application field of electronic products, touch panels combined with display panels and input devices have become fashionable equipment for high-end fashion electronic products.

There are many types of touch panel application technologies, which can be divided into resistive, capacitive, surface acoustic wave, infrared, etc. At present, resistive touch panel is the mainstream in the market, and its market size accounts for about 59% of the overall touch panel market, followed by capacitive touch panel, accounting for about 22%, and the remaining share is not large. Although resistive touch panel products have disadvantages such as poor light transmittance and poor durability, they have the advantages of low unit price and thin thickness. For downstream applications, there are many small and medium-sized consumer and communication electronic products with huge consumption. Therefore, the market It is also the largest. However, capacitive touch panels, which are used in large quantities, can only perform single-point touch compared to resistive touch panels. Although capacitive touch panels are slightly more expensive, they have better durability (dustproof, scratch-proof) and multi-point recognition functions. In addition, commands such as zooming in on the screen or dragging can be easily performed, so a more humanized and intuitive operation can be achieved. Attracted by the application of multi-touch technology and the imminent expiry of related capacitive touch panel technology patents, many manufacturers have invested in the development of the capacitive touch market.

With the increasing popularity of glass capacitive touch panels, the application of glass in handheld devices is also becoming more and more extensive. Generally speaking, there are glass used for plating touch conductive layer, and protective glass used as a part of the structure of handheld devices, as screen and touch panel protection. The former requires high light transmittance, while the latter is usually structurally strengthened glass, which requires properties such as anti-fouling, dust-proof, scratch-resistant, and impact-resistant. In order to prevent scratches or other damages on the surface of the existing touch panel, the surface of the existing touch panel is provided with an encapsulation cover (i.e. strengthened glass), so that the existing touch panel has three layer substrate, resulting in an increase in the thickness of the touch panel. In order to prevent the surface of the touch panel from getting dirty easily, an anti-fouling coating is applied to the surface of the package cover to improve the anti-fouling ability of the package cover. The production cost of the control panel is increased.

In order to solve the above problems, the touch panel of the present invention only includes a touch display module sandwiched by a substrate and a packaging cover, which effectively reduces the thickness of the touch panel, and the packaging cover or substrate uses a substrate with a hardness of 8 or more. Materials (eg sapphire or spinel), since the package cover or substrate has good surface hardness, it is not necessary to perform additional anti-fouling coating treatment on the surface of the package cover or substrate, effectively reducing the production cost of the touch panel.
