detailed description

In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Embodiment one:

Referring to Fig. 1 , an embodiment of the present invention provides a screen, including a touch screen 1, an optically transparent adhesive layer 2 and a display screen 3, the touch screen 1, the optically transparent adhesive layer 2 and the display screen 3 are arranged sequentially from top to bottom, The optically transparent adhesive layer 2 is arranged between the touch screen 1 and the display screen 3 to bond the touch screen 1 and the display screen 3 together. Referring to FIG. 2 , the edge 21 of the optically transparent adhesive layer is provided with a sealant 4 to prevent sweat (or other liquids), dirt (including dust) and the like from entering the optically transparent adhesive layer 2 through the edge 21 . The sealant 4 can extend along a direction parallel to the edge 21 .

Referring to Fig. 3, since the keys of the mobile phone (or other electronic products) are generally arranged on both sides parallel to the longitudinal direction A of the screen, the edges 21 can be two long sides parallel to the longitudinal direction of the screen of the optically transparent adhesive layer 2. edge. However, referring to FIG. 4 , the edge 21 may also be the peripheral edge of the optically transparent adhesive layer 2 , that is, the optically transparent adhesive layer 2 is provided with a sealant around the periphery, so that the protection effect is better.

Referring to Fig. 2, the width of the touch screen 1 is greater than the width of the display screen 3 (the width direction of the touch screen, the width direction of the display screen and the width direction B of the screen are consistent), and the sealant 4 is close to the touch screen 1 toward The lower surface 13 of the display screen 3, and the thickness of the sealant 4 is greater than the thickness of the optically transparent adhesive layer 2 so that the sealant part is attached to the edge of the display screen 3 (the thickness direction of the touch screen 1, the optically transparent adhesive layer 2 The thickness direction of the screen and the thickness direction L of the screen are consistent), which can improve the sealing effect. The cross-sectional shape of the sealant is shown as a triangle in FIG. 2 , but the cross-sectional shape of the sealant can also be but not limited to a square.

The sealant is made of cured glue with high viscosity, water resistance and oil resistance. The sealant is mainly used for dustproof and waterproof, and the material of the sealant can be selected from a strong adhesive (with good sealing performance, heat and humidity resistance, water resistance, oil resistance, aging resistance, temperature resistance, and solvent-free Adhesive base material has no corrosion, no pollution, no pollution to the environment), the light transmission of the sealant is not required, for example, the glue with poor light transmission can be selected.

The material of the sealant is PUR03.

Referring to FIG. 1 and FIG. 2 , the touch screen 1 includes a cover layer 11 and a touch sensing layer 12 below the cover layer 11 , and the optically transparent adhesive layer 2 is disposed between the touch sensing layer 12 and the display screen 3 .
