Method for manufacturing touch-control plate

Abstract

The invention relates to a method for manufacturing a touch-control plate, which is characterized by comprising the following steps: (a) selecting a transparent glass plate with larger area and the width larger than that of a base plate layer of a finished touch-control plate product as a base plate layer; (b) taking a rectangular transparent glass plate with area specifications matched with that of the base plate layer and the width larger than that of a panel layer of the finished touch-control plate product as a panel layer; (c) aligning the base plate layer and the panel layer and then overlying the base plate layer and the panel layer and also adhering and overlying two plate bodies of the base plate layer and the panel layer into a combined plate body through each adhering frame positioned on the plate bodies of the base plate layer and the panel layer and sealing frames positioned at the peripheries of the plate bodies; (d) carrying out a thinning manufacture procedure, i.e. the combined plate body of the base plate layer and the panel layer is etched by a hydrofluoric acid solution; (e) carrying out a cutting manufacture procedure; and (f) carrying out splitting operation along grooves of the base plate layer, i.e. the base plate is pressed, split and cut into a plurality of independent finished touch-control plate products along a predetermined cutting line.

Description

technical field [0001] The invention relates to a manufacturing method of a touch panel, in particular, a touch panel suitable for manufacturing a panel layer and a substrate layer by using a glass plate, and a plurality of touch panels can be simultaneously obtained in one manufacturing process manufacturing method. Background technique [0002] Touch panel (Touch Panel) is an input component configured on a frame surface such as a liquid crystal display (LCD) or a cathode ray tube (CRT), allowing the user to follow the instructions on the transparent screen screen with fingers or The tip of a pen is pressed from above to detect the pressed position, so as to perform position input; and the structure of a general touch panel, such as a resistive touch panel, is roughly made of two-sided resistive films separated by a certain gap. Opposed configuration, usually the upper resistive film is disposed on the surface of a flexible transparent film or thin glass panel layer, and ...

Problems solved by technology

In recent years, with the continuous improvement of the performance and production quality of touch panels, as well as the sharp reduction in prices, touch panels have gradually been widely used in various electronic products. However, in some special applications, such as satellites equipped in vehicles The touchpad used on the navigator, this kind of touchpad is often used under strong sunlight and must have the characteristics of high temperature resistance, so its panel layer material is not suitable for the commonly used plastic film, it is best to use Use a glass plate with no polarization and high temperature resistance, but because the glass material is hard and brittle, and when it is used as a panel layer, it must be very thin, for example, it must be less than 0.25mm in order to have touchability. In addition , the strength of this thin glass plate is not good, so it is only suitable for manufacturing some small-area touch panels. It is easy to cause damage during the cutting process, and it is difficult to keep the thin layer flat during the process of pasting and assembling, which may easily lead to the formation of optical interference phenomena, such as Newton rings, and it is also easy to residual stress between the layers, thereby reducing the thickness of the glass thin layer. Strength and Durability

As mentioned above, it can be known that the production of glass-type touch panels used in vehicles faces many difficulties, and the product failure rate is high, especially for touch panels with an area greater than 150mm in length and width, so its output is not enough. High and expensive, currently only used in a few high-end RVs

[0003] Therefore there is above-mentioned inconvenience and problem in the manufacture method of known touch panel
