Description

Technical Field

[0001] The utility model belongs to the technical field of glass, and particularly relates to a structure of a fully glass-based ultra-narrow border touch display for preventing edge light leakage. Background Art

[0002] In touch display products, an ineffective area of 10-30 mm is usually left on the front glass cover plate. Black light-shielding ink is printed in this ineffective area to prevent light leakage from the edge of the display, which may affect the visual and appearance effects of the display. The printed area is covered by a border during final assembly. The border is also used to fix the backlight module, liquid crystal, and front cover plate, and then integrated into a complete touch display product. However, this assembly method results in a relatively wide border, which affects the aesthetic degree of the product and also reduces the effective display area of the display product. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a structure of a fully glass-based ultra-narrow border touch display for preventing edge light leakage, so as to solve the technical problems that the assembly method has a relatively wide border, which affects the aesthetic degree of the product and also reduces the effective display area of the display product, and achieve the purpose of adopting a fully glass structure, coating light-shielding ink on the end face of the display product to prevent edge light leakage, and controlling the ineffective area within 2 mm.

[0004] To solve the above technical problems, the utility model provides a structure of a fully glass-based ultra-narrow border touch display for preventing edge light leakage, including a fully laminated:

[0005] A glass diffuser plate, a back cover plate glass, and a liquid crystal screen. The back cover plate glass is in a U shape and its end is arranged on the side of the glass diffuser plate. LED lamp beads are arranged on one side of the back cover plate glass facing the glass diffuser plate;

[0006] The liquid crystal screen is fully laminated on the side of the glass diffuser plate away from the back cover plate glass. A touch film and a front cover plate glass are sequentially and fully laminated on the side of the liquid crystal screen away from the glass diffuser plate;

[0007] A light-shielding ink layer is arranged on the side edges of the front cover plate glass, the touch film, the liquid crystal screen, and the glass diffuser plate.

[0008] Further, a fillet is arranged on the outer side of the side edge of the light-shielding ink layer, and the width of the fillet is 1 mm.

[0009] Further, the thickness of the light-shielding ink layer is 0.3-0.5 mm.

[0010] Further, the back cover plate glass and the glass diffuser plate are bonded through a frame adhesive layer.

[0011] Furthermore, a first OCA adhesive layer is provided between the glass diffusion plate and the liquid crystal screen.

[0012] Furthermore, a second OCA adhesive layer is provided between the liquid crystal screen and the touch film.

[0013] Furthermore, a third OCA adhesive layer is provided between the touch film and the front cover glass.

[0014] The beneficial effects of the utility model are:

[0015] 1. By applying light-shielding ink on the end faces of each glass component and the R-shaped bevel of the light-emitting surface of the front glass cover plate, light leakage from the edge of the display product is avoided.

[0016] 2. By fully bonding the glass components together, the edges can be fixed without frames, the border of the touch product can be reduced, the material consumption can be reduced, the display effect can be improved, and the appearance of the product can be enhanced.

[0029] Embodiment:

[0030] As Figure 1 shown, a structure of a fully glass-based ultra-narrow bezel touch display for preventing edge light leakage includes a fully laminated: glass diffusion plate 1, back cover glass 2 and liquid crystal screen 3. The back cover glass 2 is in a U shape and its end is disposed on the side of the glass diffusion plate 1. The back cover glass 2 and the glass diffusion plate 1 are bonded through a frame adhesive layer 7 to improve the connection stability between the back cover glass 2 and the glass diffusion plate 1.

[0031] Among them, an LED lamp bead 21 is disposed on one side of the back cover glass 2 facing the glass diffusion plate 1.

[0032] At the same time, a liquid crystal screen 3 is fully laminated on one side of the glass diffusion plate 1 away from the back cover glass 2. In this embodiment, a first OCA adhesive layer 11 is disposed between the glass diffusion plate 1 and the liquid crystal screen 3. A touch film 5 and a front cover glass 6 are sequentially and fully laminated on one side of the liquid crystal screen 3 away from the glass diffusion plate 1. A second OCA adhesive layer 31 is disposed between the liquid crystal screen 3 and the touch film 5 to improve the connection stability between the liquid crystal screen 3 and the touch film 5.

[0033] In this embodiment, a third OCA adhesive layer 51 is disposed between the touch film 5 and the front cover glass 6 to improve the connection stability between the touch film 5 and the front cover glass 6.

[0034] In this embodiment, a light-shielding ink layer 4 is disposed on the sides of the front cover glass 6, touch film 5, liquid crystal screen 3 and glass diffusion plate 1. Among them, a fillet is disposed on the outer side of the side of the light-shielding ink layer 4, and the width of the fillet is 1 mm. The thickness of the light-shielding ink layer 4 is 0.3 - 0.5 mm.

[0035] In summary: By coating light-shielding ink on the end faces of each glass component and the R-shaped bevel of the light-emitting surface of the front cover glass at the forefront, light leakage at the edges of the display product is avoided. By fully laminating, each glass component is combined into one body, avoiding fixing with a frame at the edges, reducing the bezel of the touch product, thereby reducing material usage, and improving the display effect and the aesthetics of the product.
