Description

Technical Field

[0001] The utility model relates to the field of display technology, in particular to a fully laminated display screen and a display module. Background Art

[0002] As demands for the reliability of automotive displays increase, the thickness of displays has increased, leading to yellowing issues during the full lamination of the display and cover. To reduce yellowing, a softer laminating adhesive is used, but this also creates a risk of delamination at the edges of the display. To improve bonding strength, the amount of topcoat applied during the full lamination process is increased. However, due to factors such as glue viscosity and dispensing speed, the topcoat can easily extend beyond the frame glue, causing glue overflow. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the utility model provides a fully laminated display screen and a display module, the purpose of which is to improve the bonding strength of the display screen and prevent the edges of the display screen from coming apart and overflowing.

[0004] The technical solutions adopted in this utility model are as follows:

[0005] The utility model provides a fully laminated display screen, comprising display screen glass, wherein an outer frame glue is provided around the edge of one side surface of the display screen glass, a surface glue coating area is formed within the outer frame glue, an inner frame glue is provided within the surface glue coating area, the inner frame glue comprises a first frame glue, which is provided on both sides of the surface glue coating area in a first direction, and the first frame glue on each side comprises at least two first unit segments arranged at intervals;

[0006] A first buffer channel is formed between the outer frame glue and the first frame glue, and a first gap communicating with the first buffer channel is formed between the two first unit segments.

[0007] Further technical solutions are:

[0008] The inner frame glue includes a second frame glue, which is arranged on both sides of the second direction of the surface glue coating area, and the second frame glue on each side includes at least two second unit segments arranged at intervals; a second buffer flow channel is formed between the outer frame glue and the second frame glue, and a first gap connected to the second buffer flow channel is formed between the two second unit segments.

[0009] A second gap is formed between the second sealant and the first sealant adjacent thereto, and the second gap is communicated with both the first buffer channel and the second buffer channel.

[0010] The distance between the second sealant and the outer sealant is 1 to 3 mm.

[0011] The distance between the first sealant and the outer sealant is 1 to 3 mm.

[0012] The distance between the outer frame glue and the edge of the display screen glass is 1 mm.

[0013] The height of the outer frame glue above the surface of the display screen glass is 0.25 to 0.35 mm.

[0014] The height of the inner frame glue above the surface of the display screen glass is 0.25 to 0.35 mm.

[0015] The display screen glass includes a polarizer, and the outer frame glue and the inner frame glue are arranged on the polarizer.

[0016] The utility model also provides a display module, including the fully laminated display screen.

[0017] The beneficial effects of the utility model are as follows:

[0018] This utility model installs inner frame glue within the inner ring of the outer frame glue. On the one hand, this increases the frame glue area, improving overall adhesion and compensating for the insufficient adhesion caused by the use of soft bonding glue. On the other hand, the inner frame glue forms a new dispensing area, and the glue amount is calculated based on the area of the dispensing area. If too much glue is dispensed during operation, the dispensing area will overflow. The glue can flow into the buffer channel through the gap and be blocked by the outer frame glue, thus avoiding the problem of glue overflow. This utility model solves the problems of glue delamination and glue overflow while improving the bonding strength.

[0019] Other features and advantages of the present invention will be described in the following description or will be understood through implementation of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The specific implementation of the present utility model is described below with reference to the accompanying drawings.

[0024] Example 1

[0025] like Figure 1As shown, the fully bonded display screen of this embodiment includes a display screen glass 1, an outer frame glue 2 is provided around the edge of one side surface of the display screen glass 1, a surface glue coating area 7 is formed in the outer frame glue 2, an inner frame glue is provided in the surface glue coating area 7, and the inner frame glue includes a first frame glue 31, which is provided on both sides of the surface glue coating area 7 in a first direction, and the first frame glue 31 on each side includes at least two first unit segments arranged at intervals;

[0026] A first buffer channel 5 is formed between the outer sealant 2 and the first sealant 31 , and a first gap 4 communicating with the first buffer channel 5 is formed between the two first unit segments.

[0027] This embodiment, by providing inner and outer frame glue, increases the frame glue area, improves the overall adhesion, and compensates for the insufficient adhesion caused by the use of soft bonding glue. On the other hand, a new glue dispensing area is formed by the inner frame glue, and the glue amount is calculated based on the area of the glue dispensing area. If too much glue is dispensed during operation, the glue dispensing area will overflow. The glue can flow into the first buffer channel 5 through the gap 4 and be blocked by the outer frame glue, thereby avoiding the problem of glue overflow.

[0028] As a preferred embodiment, the distance between the first sealant 31 and the outer sealant 2 is 1 to 3 mm.

[0029] As a preferred embodiment, the distance between the outer frame glue 2 and the edge of the display glass 1 is 1 mm.

[0030] As a preferred embodiment, the height of the outer frame glue 2 above the surface of the display screen glass 1 is 0.25 to 0.35 mm.

[0031] As a preferred embodiment, the height of the inner frame glue above the surface of the display glass 1 is 0.25 to 0.35 mm.

[0032] Specifically, the display glass 1 is a liquid crystal display screen, including a polarizer, and the outer frame glue 2 and the inner frame glue are set on the polarizer. The display glass 1 is fully bonded to the cover plate to form a fully bonded display screen, which is then combined with the backlight to form a liquid crystal display module.

[0033] This embodiment also provides a display module, including the fully laminated display screen.

[0034] Example 2

[0035] like Figure 2 As shown, the full-fit display screen of this embodiment is different from that of Example 1 in that: the inner frame glue also includes a second frame glue 32, which is arranged on both sides of the second direction of the surface glue coating area 7, and the second frame glue 32 on each side includes at least two second unit segments arranged at intervals; a second buffer channel 6 is formed between the outer frame glue 2 and the second frame glue 32, and a first gap 4 connected to the second buffer channel 6 is formed between the two second unit segments.

[0036] As a preferred embodiment, the second direction is perpendicular to the first direction.

[0037] As a preferred embodiment, a second gap 8 is formed between the second sealant 32 and the adjacent first sealant 31 , and the second gap 8 is communicated with both the first buffer channel 5 and the second buffer channel 6 .

[0038] As a preferred embodiment, the distance between the second sealant 32 and the outer sealant 2 is 1 to 3 mm.

[0039] This embodiment further optimizes the structure of the inner frame glue. The second frame glue and the first frame glue form an open circle, forming a glue dispensing area inside. The glue amount is calculated based on the area of the glue dispensing area. When the glue dispensing amount is too much during operation, the glue dispensing area overflows. The glue can flow into the first buffer channel 5 and the second buffer channel 6 through the gap 4 and be blocked by the outer frame glue, thereby avoiding the problem of glue overflow. The second frame glue and the first frame glue are distributed along a circle in the circumferential direction, which is conducive to the uniform overflow of glue into the first buffer channel 5 and the second buffer channel 6, making the surface glue distribution more uniform. At the same time, compared with Example 1, the area of the inner frame glue is further increased, and the stability of the bonding is improved.
