Description

Surface cover assembly

This creation relates to a surface cover, and more particularly to a surface cover assembly that is arranged for use in front of a touch display device.

Point-of-sale terminal devices (POS), automatic teller machines (ATMs), smart interactive navigation devices, automatic ticketing systems, gaming, entertainment and gaming machines, etc., which are widely used in public places, are currently equipped with touch display devices for user convenience. A cover lens is provided on the touch display device to protect the surface of the touch display device from being scratched or stained. Since such public electronic devices are operated by various users, Therefore, the surface cover must be particularly required to have impact resistance, surface scratch resistance and other properties. In addition, most of these public electronic devices are installed outdoors or in places with bright light. In these occasions, the surface of the surface cover is very It is easy to produce reflection or glare, which causes the screen display information to be unclear, or the image color to be dim and blurred. In order to overcome the aforementioned unfavorable features, an anti-glare surface (AG) or anti-reflection is usually provided on the surface cover. Optical functional surfaces such as surfaces (AR). In addition, decorative borders or icons (ICON) are also provided on the surface cover to improve aesthetics.

In order to meet the high-strength and optical functional requirements of the aforementioned surface cover, the current general practice in the industry is to use a single-piece glass sheet with a larger thickness in order to meet the strength requirements of the board, and directly perform chemical etching or Processing processes such as coating to form the required optical functional surface and decorative frame on the surface of the surface cover; however, such surface covers used in public electronic equipment have a relatively large area, in order to ensure that the board has the required Strength, so often need to choose a glass plate with a thickness of more than 10mm to use, and as is known, the larger the area of use, the thickness must be correspondingly larger, so the weight of the board will be doubled, and the huge weight It will cause the board to have difficulties in the related processing operations, such as the difficulty of clamping, fixing, moving, or changing the work of the board, so it is not easy to directly perform the optical functional surface on the surface cover. , Decorative frame or icon (ICON) and other processing processes; in addition to the thickness of the board, the requirements for the strength and optical characteristics of the surface cover, etc. It is often different due to different machines used for configuration, so producers cannot standardize mass production, resulting in low production efficiency and high cost. In addition, the surface cover used in this type of public electronic equipment is used in different ways. The operator's operation and use can easily lead to the problem of contact cross infection; the aforementioned shortcomings need to be overcome urgently.

This creation provides a surface cover plate assembly composed of a plurality of laminates. According to the required functional characteristics of the surface cover plate, the board body is divided into a plurality of standardized laminated components, and the individual standardized laminates are laminated. The component has a corresponding thickness dimension and optical functionality or antibacterial functionality. According to the requirements of the use, the surface cover can be easily and quickly formed to meet the required thickness dimension and optical functionality or antibacterial functionality for use; This creation has the advantages of increasing production capacity and reducing costs, and its production capacity is fast and suitable for customized small and diverse product orders, which can increase the flexibility of production and sales business and product competitiveness; in addition, this creation makes These laminated components are thinned and lightened, which can eliminate the disadvantages of difficult processing and application, and facilitate the processing of various optical functional surfaces, antibacterial functional surfaces, or decorative frames directly on the laminated components. Save processing costs and improve product durability.

This will further clarify the other functions and technical features of this creation below. Those skilled in the art will be able to realize this creation after reading the description in the article.

The surface layer 10 is a thin sheet with high light transmittance having excellent mechanical strength, such as various glass or polymethyl methacrylate (PMMA). The thickness of the surface layer 10 is set to be equal to or less than 3 mm, so that the plate body The material itself or the method of forming a hardened layer on the surface of the board by processing, so that the surface layer has a surface hardness greater than 7H (pen tip hardness); its upper surface is a Functional Surface 101, the functional surface 101 It can be one or both of the optical function surface and the antibacterial function surface, and the peripheral edge area of the bottom surface is provided with an opaque or low light transmittance decorative frame 102. The decorative frame 102 is made of ink or Photoresist and other insulating materials; because the surface layer 10 is relatively thin, it is convenient to perform related processing on the surface layer 10 to form an optically functional surface or an antibacterial functional surface. For example, chemical etching can be used. hand The segment is made with a fine rough surface on its upper surface to form an anti-glare surface (AG), an anti-glare surface (AR) is formed on the upper surface using a coating method, or an anti-glare surface is formed on the upper surface using an optical film coating method ( AG) or anti-reflective surface (AR), or metal ions such as silver, copper, zinc, etc. can be set on the upper surface by spraying, coating, antibacterial film or chemical etching to form an antibacterial functional surface. It has bacteriostatic and sterilizing functions; in addition, the aforementioned insulating material is provided on the bottom surface of the surface layer 10 to form a decorative frame 102 by implementing technical means such as printing and coating.

The intermediate layer 20 is a thin sheet with high light transmittance, such as various glasses of rigid sheet, polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), polycarbonate (PC), or ring. Olefin copolymers (COC / COP), etc., or polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polyethylene (PE), polypropylene (PP) as flexible films ), Polyetheretherketone (PEEK), polyfluorene (PSF), polyetherfluorene (PES), polycarbonate (PC), cyclic olefin copolymer (COC / COP), polyfluorene, polyfluorene, Acrylic resin, vinyl series resin, trivinyl cellulose (TAC), etc .; the thickness of the intermediate layer 20 is set to be equal to or less than 4 mm.

The bottom layer 30 is a thin sheet with high light transmittance, such as various glass, polymethyl methacrylate (PMMA), polyethylene terephthalate (PET), polycarbonate (PC) or cycloolefin copolymerization. (COC / COP), etc .; the thickness of the bottom surface layer 30 is set to be equal to or less than 3 mm.

The aforementioned surface layer 10, two intermediate layers 20, and bottom surface layer 30 are sequentially stacked, and the layers are bonded together by an optical glue 40. According to this, each layer can form a board with a thickness of about 14 mm and an optical function surface 101. And the surface cover assembly of the decorative frame 301; the optical adhesive 40 may be a solid optical adhesive film (OCA) or a liquid optical resin (OCR).

According to the above description, the thickness of the surface cover plate assembly can be adjusted by increasing or decreasing the number of the intermediate layer 20 provided.
