Description

Technical Field

[0001] The utility model belongs to the field of touch screens, and in particular relates to a touch screen with improved cleanliness. Background Art

[0002] A touch screen is an inductive liquid crystal display device that can receive input signals such as contacts, and can replace mechanical button panels. With the continuous development of technology, various electronic products are emerging in an endless stream. For example, portable electronic products such as smart phones and tablets, as well as computers and household appliances are gradually beginning to use touch screens as operating interfaces for human-computer interaction between users and electronic devices. Users can perform touch, drag and gesture operations when using, which can make human-computer interaction simpler, more intuitive and more user-friendly, and also conform to the development trend of thinner and lighter electronic products. In the existing production of touch screens, protective glue is usually only printed on the visible window of the touch screen. In the close fit between the display panel and the touch screen, subsequent manual wiping work is added, which increases the steps and inconvenience of manual operation. In addition, heat will be generated under long-term use of the touch screen. The existing ones usually do not have heat dissipation for the touch screen, and only a heat dissipation structure is provided on the whole machine, which brings the inconvenience of low heat dissipation effect to the use of the touch screen, and also has a low service life. Utility Model Content

[0003] The utility model aims to provide a touch screen with improved cleanliness, which has the advantages of increasing the cleanliness and the heat dissipation effect of the touch screen.

[0004] The above technical purpose of the utility model is achieved through the following technical scheme: a touch screen with improved cleanliness, comprising a display panel, the display panel comprising a cover glass, a circuit substrate is provided at the bottom of the cover glass, a protective glue is adhered between the circuit substrate and the cover glass, a front panel is provided at the bottom of the circuit substrate, a back panel is fixedly adhered to the bottom of the front panel, and a heat dissipation film is fixedly adhered to the bottom of the back panel.

[0005] The above technical solution is adopted: in the use of the touch screen, the protective glue is an OCA optical glue. Through the setting of the protective glue, the visible window and the non-visual window of the cover glass are covered, which is different from the existing coverage of only the visible window, resulting in the tediousness of subsequent manual wiping. By increasing the coverage of the non-visual window by the protective layer, the cleaning effect of the touch screen is increased. The OCA optical glue will play a role in eliminating dust and maintaining the cleanliness of the display panel. At the same time, the reflection of the display panel to light is reduced by the protective layer, and the firmness of the display panel is improved. This structure increases the practicality and convenience of use of the touch screen and reduces the tediousness of subsequent manual wiping. At the same time, through the use of the heat dissipation film, the heat generated by the long-term use of the touch screen will be dissipated through the setting of the heat dissipation film, which is convenient for heat dissipation. The heat dissipation film is a heat dissipation graphite film, which increases the heat dissipation coefficient of the bottom of the back plate. The heat dissipation film is different from the existing heat dissipation structure of the whole machine, which has a low heat dissipation effect on the touch screen, increases the heat dissipation effect of the touch screen, and ensures the service life of the touch screen.

[0006] The utility model is further configured that a protective layer is fixedly adhered to the top of the display panel.

[0007] Using the above technical solution: the protective layer is a thin film layer that brings a firm effect to the surface of the display panel.

[0008] The utility model is further configured that the protective layer is an anti-reflection protective layer.

[0009] By adopting the above technical solution, the reflection of light by the display panel is reduced by the protective layer, while the firmness of the display panel is improved.

[0010] The utility model is further configured that the surface of the cover glass is respectively formed with a visible window and a non-visual window.

[0011] The above technical solution is adopted: the touch screen is used in coordination with the visible window and the non-visual window.

[0012] The utility model is further configured that the protective glue is OCA optical glue.

[0013] The above technical solution is adopted: OCA optical glue can eliminate dust and maintain the cleanliness of the display panel.

[0014] The utility model is further configured such that the protective adhesive covers the visible window and the non-visual window.

[0015] Adopting the above technical solution: covering the visible window and the non-visual window with protective glue will reduce the tediousness of subsequent manual wiping.

[0016] The utility model is further configured that a conductive layer is fixedly adhered between the circuit substrate and the front panel.

[0017] The above technical solution is adopted to achieve the purpose of absorbing and shielding electromagnetic waves through the conductive layer.

[0018] The utility model is further configured that the heat dissipation film is a heat dissipation graphite film.

[0019] The above technical solution is adopted: the heat dissipation coefficient of the bottom of the back plate is increased by using the graphite material of the heat dissipation film.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In the use of the touch screen of the utility model, the protective glue is an OCA optical glue. Through the setting of the protective glue, the visible window and the non-visual window of the cover glass are covered. The difference is that the existing only covers the visible window, which leads to the cumbersomeness of subsequent manual wiping. By adding the coverage of the non-visual window by the protective layer, the cleaning effect of the touch screen is increased. The OCA optical glue will play a role in eliminating dust and maintaining the cleanliness of the display panel. At the same time, the protective layer reduces the reflection of light by the display panel and improves the firmness of the display panel. This structure increases the practicality and convenience of the touch screen and reduces the cumbersomeness of subsequent manual wiping.

[0022] 2. The utility model uses a heat dissipation film. When the touch screen is used for a long time, the heat generated will be dissipated through the setting of the heat dissipation film, which is convenient for heat dissipation. The heat dissipation film is a heat dissipation graphite film, which increases the heat dissipation coefficient of the bottom of the back plate. The heat dissipation film is different from the existing heat dissipation structure of the whole machine, which has a low heat dissipation effect on the touch screen. The heat dissipation effect of the touch screen is increased to ensure the service life of the touch screen. BRIEF DESCRIPTION OF THE DRAWINGS
