Description

Technical Field

[0001] The utility model relates to the technical field of display modules, in particular to an integrated touch display module for preventing buffer foam from being damaged and shedding chips. Background Art

[0002] When the display module is assembled into a complete machine for use, there is usually a risk of drop damage. For example, when the complete machine of the display module drops instantaneously, the impact force is transmitted from the middle frame of the complete machine to the integrated touch display module, and the impact force acts on the backlight module, thereby squeezing the glass single-layer area in the display screen, and then easily causing the problem of cracking of the glass single-layer area in the display screen. Therefore, it is necessary to add a buffer foam on the back of the backlight module for buffering to reduce the external force impact on the backlight module.

[0003] However, after the buffer foam is added to the integrated touch display module, if the surface of the buffer foam is affected by external force and is damaged and prone to shedding chips before the customer assembles it, the protection performance of the buffer foam will be affected. In addition, if the buffer foam is misaligned when attached to the backlight and needs to be torn off for rework, since the foam is in a fluffy state and is not easily torn up at one time, it is easy to have foam residues on the surface of the backlight module, affecting the rework effect. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide an integrated touch display module for preventing buffer foam from being damaged and shedding chips, which can not only prevent the foam from being damaged and shedding chips, but also avoid the foam residues on the surface of the backlight module.

[0018] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required to be used in the embodiments will be briefly introduced below.

[0021] Figure 3 For Figure 1 A partial enlarged structural schematic diagram of the integrated touch display module for preventing the buffer foam from being damaged and shedding chips at location A in Specific embodiments

[0022] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0023] Please refer to Figure 1 , Figure 2 and Figure 3 As shown in , an integrated touch display module for preventing the buffer foam from being damaged and shedding chips includes: a cover plate 100, a display screen 200, a backlight module 300 and a buffer foam assembly 400. The cover plate 100, the display screen 200 and the backlight module 300 are stacked in sequence; the buffer foam assembly 400 includes an anti-residual protective layer 410, a foam layer 420 and an anti-chip-shedding protective layer 430. The anti-residual protective layer 410, the foam layer 420 and the anti-chip-shedding protective layer 430 are stacked in sequence, and the anti-residual protective layer 410 is attached to the side surface of the backlight module 300 away from the display screen 200.

[0024] It should be noted that, that is, by providing the buffer foam assembly 400 on the side surface of the backlight module 300 away from the display screen 200, the single-layer area of the display screen 200 is buffer-protected by the buffer foam assembly 400, and the impact force acting on the backlight module 300 and then squeezing the glass single-layer area of the display screen 200 is reduced. At the same time, by adding an anti-residual protective layer 410 and an anti-chip-shedding protective layer 430 on the left and right sides of the foam layer 420 respectively, in this way, when the buffer foam assembly 400 is removed during repair, the anti-residual protective layer 410 can be torn up and the foam layer 420 can be taken up together, thereby preventing foam from remaining on the surface of the backlight module 300. At the same time, by providing the anti-chip-shedding protective layer 430, it plays an isolation and protection role for the foam layer 420 to avoid the foam layer 420 being damaged and shedding chips after being subjected to external force.

[0025] In an embodiment, the anti-residual protective layer 410 is an anti-residual PET protective film. A first adhesive layer is provided on the side surface of the anti-residual PET protective film away from the foam layer 420, and a second adhesive layer is provided on the side surface of the anti-residual PET protective film close to the foam layer 420. By adding an anti-residual PET protective film on the foam layer 420, when repair is needed, the anti-residual PET protective film can be torn off, and then the foam layer 420 can be taken up together by the anti-residual PET protective film. In this way, foam can be prevented from remaining on the surface of the backlight module 300.

[0026] Preferably, the second adhesive layer is glue or double-sided tape.

[0027] In one embodiment, the anti-chip-off protective layer 430 is an anti-chip-off PET protective film, and a third adhesive layer is provided on one side of the anti-chip-off PET protective film close to the foam layer 420. The anti-chip-off PET protective film has very high tensile strength and impact resistance, and has the advantages of wear resistance and puncture resistance. Therefore, by providing the anti-chip-off PET protective film on the surface of the foam layer 420, not only can the risk of the foam layer 420 being damaged by external forces be reduced, but also the chip-off of the foam layer 420 can be prevented.

[0028] Preferably, the third adhesive layer is glue or double-sided tape.

[0029] In one embodiment, the anti-residue protective layer 410, the foam layer 420 and the anti-chip-off protective layer 430 are an integrally die-cut structure. That is, when manufacturing the buffer foam assembly 400, the large anti-residue protective layer 410, the foam layer 420 and the anti-chip-off protective layer 430 are first adhesively bonded and connected with an adhesive, and then uniformly die-cut with a die-cutting knife to improve production efficiency.

[0030] Preferably, the cover plate 100 is a glass cover plate 100.

[0031] Specifically, the display screen 200 includes a polarizer 210, an upper glass sheet 220, a lower glass sheet 230 and a polarizer 240 which are sequentially stacked.

[0032] Specifically, the cover plate 100 and the display screen 200 are adhesively bonded and connected through an OCA optical adhesive. The OCA optical adhesive is a special adhesive, which has high light transmittance and high bonding strength, so it can ensure the connection firmness between the cover plate 100 and the display screen 200.

[0033] Specifically, the backlight module 300 includes a backlight frame and a backlight film material. A limiting cavity is opened on the backlight frame, and the backlight film material is arranged in the limiting cavity. The buffer foam assembly 400 is arranged on the backlight frame. The backlight film material includes an upper brightness enhancement film, a lower brightness enhancement film, a diffusion film, a light guide plate, a reflector, etc.

[0034] The above embodiments only represent several embodiments of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
