Embodiment 1

[0025] A manufacturing process for a full-fit curved touch display screen, comprising the following steps:

[0026] 1) Pre-lamination: pre-laminate the sequentially overlapping ultra-thin glass 11, touch film 12, and plexiglass 13 with solid ultraviolet flexible glue 10, the thickness of the solid ultraviolet flexible glue is 50-100 μm;

[0027] 2) Hot bending: such as figure 2 As shown, the pre-laminated components are placed on the hot bending device and heated on one side to form the required arc. The bending temperature is 30-40°C, the time is 1-20min, and the arc is 5-30; The device includes a heating plate 2 with a heating component 3 at the bottom of the heating plate 2;

[0028] 3) OLED display bending: place the OLED display on a mold with the same curvature as the pre-laminated component and bend it naturally;

[0029] 4) Use solid ultraviolet flexible glue to bond the hot-bent pre-laminated components and the curved OLED display into a pre-laminated integrated sc...

Embodiment 2-3

[0036] Using the same preparation method as in Example 1, the difference is that the thickness, pressure, temperature, time and curvature in the pre-lamination, degassing and heat bending steps listed in Table 1 are used to replace the corresponding ones used in Example 1. Numerical values ​​to form full-fit curved touch screens of different sizes.

[0037] Table 1

[0038]

[0039] In the embodiment, if the thickness of the solid ultraviolet flexible adhesive is less than 50 μm, the fluidity is not enough, and thickness difference is likely to occur. If the thickness is higher than 300 μm, the fluidity is too full and overflowing glue is likely to occur. If the temperature and pressure are lower than the limit value, the solid ultraviolet flexible adhesive will not be easily bonded to each component; during the defoaming process, the temperature is 30-65°C, the pressure is 0.5-10kg, and the defoaming time is 10-250 minutes. If the value is higher than the limit value, the ...

Abstract

The invention discloses a manufacturing process for a fully-laminated curved touch display screen. The manufacturing process comprises the following steps: pre-laminating a touch thin film, organic glass and ultrathin glass by adopting a solid ultraviolet flexible adhesive, performing one-sided heating on the pre-laminated components to thermally bend the pre-laminated components into a required curved shape on a thermal bending device, laminating the thermally-bent pre-laminated components and a bent OLED (Organic Light-Emitting Diode) display to form an integrated pre-laminated screen by virtue of the solid ultraviolet flexible adhesive, and performing deaeration, curing and edge sealing. The process is simple and high in yield and finished product stability, the production efficiency is greatly improved, and the service life of a product is prolonged.

Description

technical field [0001] The invention relates to the technical field of touch display screens, in particular to a full-fit curved touch screen display and a manufacturing process thereof. Background technique [0002] Compared with the flat display screen, the curved display screen can provide a wide panoramic image effect with its curved design surrounded by the direction of the user. Since any point on the screen is equal to the distance from the eyes, no matter whether the objects appear in the center or the edge of the screen, there is no problem. It will be deformed, and it also reduces the distortion of uneven viewing angle distance when viewed at close range, which can make the audience fully immersed in the wonderful and realistic pictures, and bring the audience a more realistic and comfortable look and feel. Some of the existing methods for manufacturing curved touch liquid crystal displays use a touch film attached to the hot-bending glass, and some directly use th...
