Description

Optical adhesive surface fitting device

The present invention relates to an optical glue curved surface bonding device, and more particularly to a display device structure that can completely conform to a curved glass and a liquid crystal screen module.

According to the conventional optical display, the manufacturing process is distinguished by a bonding technique, and the bonding technique can be divided into two methods: a word-fitting adhesive and a full-surface bonding. Air gap bonding is to cover the protective glass layer (Cover Lens) and the LCD screen LCM module through double-sided tape, because the production cost is low and the technical threshold is low, but the middle air layer (air) Gap) A phenomenon in which a refraction is caused by light refraction, and the image is slightly inferior, and an optical bonding (Liquid Optical Clear Adhesive) is used to protect the glass layer (Cover Lens). The LCD screen LCM mold is completely fitted. Because the two layers are completely tightly sealed, there is no gap and air layer, there is no overlap caused by light refraction, and there is a high contrast quality. There are also many advantages, such as: the screen does not enter dust, touch The module is also closely combined with the panel to increase the strength, and at the same time, it can effectively reduce the interference caused by the noise generated by the display panel on the touch signal. The all-round fit of all the above advantages has become the best fit solution for the mainstream products in the market. However, the display technology is constantly improving. In order to meet the demand for more realistic images and the visual experience of the three-dimensional space, the protective glass layer (Cover Lens) Application to design concept by 2D Developed as a 3D application, as the name suggests, curved glass is a three-dimensional glass product, which is quite different from the previous 2D flat glass. Its 3D stereoscopic glass appearance has a streamlined and three-dimensional texture with a magnifying effect, which can be widely used in various fields. In the future, the existing flat-panel touch glass will be gradually replaced. Due to the advent of 3D curved glass technology, the industry's laminating technology has a combination of two types of technology: the surface glass has no better bonding technology. carry out.

In view of the above-mentioned shortcomings, the creators of this novel believe that they have the urgent need to make corrections. They have been engaged in the design and manufacture of related products for many years, and they have always adhered to the excellent design concept, and researched and created the above disadvantages.

There is an anti-overflow rubber wall, and the anti-overflow rubber wall can be set as a retaining wall made of adhesive or a retaining wall of the template. The anti-overflow rubber wall is arranged in the display module according to different molding methods. The number of three edges adjacent to the side may be three, and the plurality of anti-overflow rubber walls disposed on the display module are respectively attached to a curved panel, and the curved transparent plate is a curved surface. The material is formed, and the curved panel is attached to a plurality of anti-overflow walls, so that a space is formed between the curved panel and the display module to inject a bonding layer, and the bonding layer is composed of a liquid transparent optical adhesive. And the two sides of the bonding layer are closely attached to the display module and the curved plate, so the structure is displayed by A plurality of anti-overflow rubber walls are formed between the module and the curved transparent plate, so that the display module and the curved panel are in a container shape, so that the liquid transparent optical adhesive can be directly injected between the two, and the display module The air between the transparent plate and the curved transparent plate is pushed by the liquid transparent optical adhesive to be discharged to the outside, so that the adhesive layer is closely attached to the display module and the curved transparent plate without any gap and air layer. The structure can improve the bottleneck of the conventional curved glass and the display, and achieve high quality and durability of the product, and then become a product that is quite in line with its progress.
