Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of touch screens, in particular to an OGS touch screen structure. Background Art
[0002] OGS touch screen is an electronic product protection screen made by directly forming ITO conductive film and sensor on protective glass. A piece of glass plays the dual role of protective glass and touch sensor at the same time. From a technical perspective, OGS technology has the following advantages over mainstream G / G touch technology: simple structure, light, thin, good light transmittance, and saves a piece of glass substrate and bonding process, which reduces production costs and improves product qualification rate.
[0003] In the prior art, although the OGS touch screen has the advantages of being thin and light and reducing costs, it is more easily damaged than traditional touch screens due to the lack of a layer of protective glass; and a higher waterproof seal is required to ensure the waterproof performance of the touch screen. Utility Model Content
[0004] The purpose of the utility model is to solve the problems existing in the prior art.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: an OGS touch screen structure, comprising: a touch screen glass, an ITO conductive film is arranged on one side of the touch screen glass, a sensor is arranged on one side of the ITO conductive film, and a sealant is coated around the surface of one side of the touch screen glass.
[0006] As a preferred implementation, a frame is provided on the surface of the touch screen glass, and a protective layer is attached to one side of the touch screen glass.
[0007] As a preferred implementation, the protective layer is made of TUP material.
[0008] As a preferred implementation, the touch screen glass is made of glass film material.
[0009] As a preferred implementation, the sealant is made of polyurethane glue.
[0010] Compared with the prior art, the advantages and positive effects of the utility model are:
[0011] 1. The utility model improves the material of the touch screen glass and uses a glass film material. Compared with the traditional tempered glass, the glass film is a unique glass material. It is made by high-temperature melting and has extremely high transparency and good wear resistance. It can also be processed into touch screen panels of various shapes and sizes. Compared with traditional glass materials, the glass film is thinner and more flexible, which can effectively improve the screen response speed and touch accuracy, allowing users to operate more conveniently and freely. At the same time, in order to improve the strength of the touch screen glass, a protective layer of TPU material is added to the surface of the touch screen glass. TPU is the full name of thermoplastic polyurethane elastomer, which is a material with good scratch resistance and anti-elasticity, so that the touch screen glass has thin and flexible performance while improving its strength.
[0012] 2. In the utility model, sealant is coated on the edges around the inner side of the touch screen glass, and the sealant wraps the inner ITO conductive film and the sensor surface around to seal. The polyurethane glue used in the sealant has good adhesion and waterproof properties, and is suitable for touch screens that require waterproof and humid environments. It ensures the connection sealing between the touch screen glass and the installation frame and improves the waterproof performance of the touch screen. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-4 The utility model provides a technical solution: an OGS touch screen structure, comprising: a touch screen glass 1, an ITO conductive film 2 is arranged on one side of the touch screen glass 1, a sensor 3 is arranged on one side of the ITO conductive film 2, and a sealant 4 is coated around the surface of one side of the touch screen glass 1.
