Description

Technical Field

[0001] The utility model relates to the technical field of display touch products, and particularly relates to a structure for reducing interference fringes between a polarizer on a bonding part and the lower surface of a TP. Background Art

[0002] With the rapid development of display touch products, most current consumer, industrial control, and vehicle-mounted display products are correspondingly equipped with touch functions, turning the original one-way information transmission mode into a human-computer interaction mode. And to reduce or decrease the overall thickness of the products, the display screen and the touch screen are usually bonded into an integral whole. Currently, there are two bonding methods: full bonding of touch and display products using OCA / OCR (liquid optical transparent adhesive), and another method is to bond the display product and the touch product through a layer of loop-shaped double-sided tape or foam adhesive. Since the double-sided tape or foam cannot be as transparent as OCA or OCR, it only fixes the relative positions of the products on the outer frame outside the VA area. This bonding method is usually called frame bonding. However, the surfaces of the existing TP (capacitive touch screen) and the display screen are both smooth, resulting in poor visibility due to mutual adsorption, thus causing problems such as interference fringes or Newton's rings. Summary of the Utility Model

[0003] To overcome the defects existing in the prior art, there is provided a structure for reducing interference fringes between a polarizer on a bonding part and the lower surface of a TP, so as to solve the problem that the surfaces of the existing TP and the display screen are both smooth, resulting in poor visibility due to mutual adsorption, thus causing interference fringes or Newton's rings.

[0004] To achieve the above object, there is provided a structure for reducing interference fringes between a polarizer on a bonding part and the lower surface of a TP, including: a frame-bonding foam, a gap, bump dots, and a display screen;

[0007] The bump dots are provided on the rear side of the TP. Multiple groups of bump dots are densely distributed on the bonding area, and the bump dots adopt a hemispherical arch structure made of solid PE material;

[0008] The display screen is installed on the rear side of the TP. The display screen is located on the installation area, and the display screen and the TP are detachably connected.

[0009] Further, an upper protective frame is provided on the upper part of the front side of the TP, a lower protective frame is provided on the lower part of the front side of the TP, a touch area is provided in the middle of the front side of the TP, and both the lower protective frame and the upper protective frame are made of PE material.

[0010] Further, the surface of the installation area on the rear side of the TP is treated with a smooth finish.

[0011] Further, double-sided tape is pasted between the frame-mounted foam and the TP and the display screen respectively. The frame-mounted foam is made of XPE material. The thickness of the frame-mounted foam is set to be the same as the thickness of the gap, and the frame-mounted foam is a detachable structure.

[0012] The beneficial effect of the present utility model is that the present utility model mainly reduces the probability of contact between the TP surface and the upper polarizer by adding auxiliary support materials, adopts a frosted and rough surface design for the polarizer, and also adopts a smooth surface design for the TP surface, so as to achieve the effects of not reducing the user experience, not increasing the frame paste gap of the product, and reducing the use cost of the main material.

[0018] The following uses specific specific examples to illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand the other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model.

[0019] Refer to Figures 1 to 3As shown in the figure, the present utility model provides a structure for reducing interference fringes between a polarizer on a bonding member and the lower surface of a TP, including: a frame bonding foam 2, a gap 3, bumps 4, and a display screen 5; the frame bonding foam 2 is bonded to the upper and lower parts of the rear side of the TP1, an installation area 14 is provided in the middle of the rear side of the TP1, and a bonding area 13 is provided outside the installation area 14; the gap 3 is provided between the TP1 and the display screen 5, and the frame bonding foam 2 is located within the gap 3; the bumps 4 are provided on the rear side of the TP1, multiple groups of bumps 4 are densely distributed on the bonding area 13, and the bumps 4 adopt a solid hemispherical arch surface structure made of solid PE material; the display screen 5 is installed on the rear side of the TP1, the display screen 5 is located on the installation area 14, and the display screen 5 is detachably connected to the TP1. An upper protective frame 12 is provided on the upper part of the front side of the TP1, a lower protective frame 10 is provided on the lower part of the front side of the TP1, and a touch area 11 is provided in the middle of the front side of the TP1.

[0020] In this embodiment, the surface of the installation area 14 on the rear side of the TP1 is smooth, a bonding area 13 is provided outside the installation area 14, and multiple bumps 4 are densely distributed on the bonding area 13.

[0021] As a preferred implementation manner, by using the design of the bumps 4 and the installation area 14, the problem of Newton's rings or interference fringes can be completely avoided. A relatively low-cost smooth polarizer on the market can be used to handle this situation, and a thinner frame bonding double-sided tape can be used for product frame bonding, achieving the target requirement of a thinner overall product for end users.

[0022] In this embodiment, double-sided tape is pasted between the frame bonding foam 2 and the TP1 and the display screen 5 respectively. The frame bonding foam 2 is made of XPE material. The thickness of the frame bonding foam 2 is set to be the same as the thickness of the gap 3, and the frame bonding foam 2 is a detachable structure.

[0023] As a preferred implementation manner, columnar supports with the same height and the same compression ratio as the frame bonding foam or double-sided tape used in the later stage are printed on the bottom layer of the TP. The optical characteristics of the support material are the same as those of air, so that the light transmission path through the columnar body is the same as the light transmission path through air, and with a thinner product bonding gap, larger particulate foreign matters can be effectively blocked from entering the product visible area, thereby improving the bonding yield of the product and preventing dirt from entering during subsequent use.

[0024] The present utility model can effectively solve the problem of poor visibility caused by mutual adsorption due to the smooth surfaces of both the TP and the display screen in the prior art, resulting in the appearance of interference fringes or Newton's rings. The present utility model mainly reduces the probability of contact between the TP surface and the upper polarizer by adding auxiliary support materials, uses a smooth polarizer, and also adopts a smooth surface design for the TP surface, simultaneously achieving the goals of not reducing the user experience effect, not increasing the product frame bonding gap, and reducing the use cost of the main material.
