Description

Technical Field

[0001] The utility model relates to the technical field of display modules, in particular to a display module structure with a camera blind hole. Background Art

[0002] In electronic devices such as mobile phones and tablets, it is usually necessary to set up a camera. Figure 1 As shown in the figure, it is a conventional structural schematic diagram of an existing display module with a camera blind hole, in which a hole is usually dug on the display module to form a camera blind hole 10a for placing a camera; wherein, since the display screen on the display module needs to be provided with an upper polarizer 10b and a lower polarizer 10c, and the polarizer does not have a high light transmittance, which will affect the shooting quality of the camera, therefore, usually in the area corresponding to the camera blind hole, it is necessary to design an opening for the upper polarizer and the lower polarizer, in order to prevent the backlight source from leaking out from between the light-shielding glue 10d and the iron frame 10e, and to prevent the backlight source from leaking out from the side edge of the opening of the lower polarizer 10c, a commonly used solution is to apply glue at the edge of the opening of the lower polarizer 10c ( Figure 1 A), and glue is applied to the side edge of the backlight module opening ( Figure 1 B). That is, this structure requires two dispensing operations, which not only requires the introduction of dispensing equipment, but also has a complicated process, which will increase the production process and production cost accordingly. At the same time, due to the certain fluidity of the glue, the size of the glue is also difficult to control, which will affect the production efficiency and production yield. Utility Model Content

[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0023] See also Figure 2 , Figure 3 and Figure 4 As shown, a display module structure with a camera blind hole includes: a liquid crystal display screen 100 and a backlight module 200, the liquid crystal display screen 100 includes an upper polarizer 110, a CF (color filter) glass 120, a TFT (thin film field effect transistor) glass 130 and a lower polarizer 140 arranged in sequence from top to bottom, and a first avoidance hole is opened on the lower polarizer 140; the backlight module 200 includes a backlight frame 210, a camera blind hole 211 is opened on the backlight frame 210, the position of the first avoidance hole corresponds to the camera blind hole 211, the backlight frame 210 is provided with a bending portion 212 around the periphery of the camera blind hole 211, an anti-light leakage support portion 213 is provided on the bending portion 212, and an anti-light leakage glue layer 214 is provided on the side of the anti-light leakage support portion 213 facing the lower polarizer 140, and the anti-light leakage glue layer 214 is used to connect the anti-light leakage support portion 213 with the TFT glass 130.

[0024] It should be noted that the camera blind hole 211 is used to assemble the camera, that is, a hole is opened at the backlight frame 210. In addition, a hole is also opened on the lower polarizer 140 to avoid affecting the shooting effect of the camera. However, after the hole is opened, the light source in the backlight module 200 will leak out, affecting the use effect. The conventional method is to dispense glue twice, such as Figure 1A and B, but the glue dispensing process is complicated, and the production process and cost must be increased. The glue size is also difficult to control, which can easily affect the production efficiency and production yield. Therefore, in the present utility model, a bending portion 212 is provided around the periphery of the camera blind hole 211 on the backlight frame 210, and the anti-light leakage support portion 213 is supported by the bending portion 212. At the same time, an anti-light leakage glue layer 214 is provided on the anti-light leakage support portion 213, and the light-shielding tape at the upper end of the opening is cancelled. The anti-light leakage support portion 213 and the TFT glass are pasted by the anti-light leakage glue layer 214. In this way, the light leakage at the first avoidance hole of the lower polarizer 140 and the side of the camera blind hole can be blocked by the anti-light leakage support portion 213 and the anti-light leakage glue layer 214. In this way, one glue dispensing operation can be omitted. Compared with the existing two-time glue dispensing structure, the number of glue dispensing times can be reduced, and the use of light-shielding glue can also be cancelled, thereby improving production efficiency and production yield. Similarly, further, a second avoidance hole is opened on the upper polarizer 110, and the position of the second avoidance hole corresponds to the camera blind hole.

[0025] Furthermore, it should be noted that there are two ways to dispense glue. One is to dispense glue after the backlight module and the LCD are assembled. Figure 2 As shown, this method of dispensing glue is more complicated. Another method is to perform dispensing glue before assembling the backlight module. Figure 3 and Figure 4 As shown, glue can be directly applied to the anti-light leakage support part 213. After assembly, the gap between the anti-light leakage support part 213 and the TFT glass is filled by pressing the TFT glass. Since the anti-light leakage support part 213 is exposed, it is easier to perform glue application.

[0026] Furthermore, the inclination angle of the bent portion 212 is less than 90°, and the free end of the bent portion 212 extends in a direction close to the center of the camera blind hole 211. The inclination angle of the bent portion 212 is less than 90°, that is, the bent portion 212 is in an inclined state, so that it is easier to set the anti-light leakage support portion 213, so that the area of ​​the anti-light leakage support portion 213 facing the lower polarizer 140 is larger, thereby facilitating the glue dispensing operation and increasing the glue dispensing area.

[0027] Furthermore, the light leakage prevention support part 213 is a plastic support part. Plastic material is relatively light, so it can reduce the overall weight of the backlight module to a certain extent. In the present embodiment, the backlight frame 210 is a metal frame, and the backlight frame 210 and the plastic support part form a colloid integrated structure, that is, a corresponding mold can be used to make the metal frame and the plastic support part integrally formed, so that the strength of the plastic support part can be ensured and the problem of the plastic support part falling off can be reduced. Furthermore, the plastic support part is a dark color such as black or gray, so as to ensure the shading effect and prevent the light source in the backlight module from being revealed. Similarly, the light leakage prevention glue layer 214 also adopts a dark color such as black or gray.

[0028] In one embodiment, the thickness of the light leakage prevention glue layer 214 is greater than or equal to 0.1 mm, so as to ensure that the light leakage prevention glue layer 214 has sufficient thickness, thereby ensuring the bonding effect.

[0029] In one embodiment, the Shore A hardness of the light leakage prevention glue layer 214 is not more than 30. In this way, the glass can be prevented from being cracked due to the glue being too hard.

[0030] In one embodiment, the viscosity of the light leakage prevention glue layer 214 is greater than 10000 CPS, so as to ensure the bonding firmness between the TFT glass and the light leakage prevention support part 213 .

[0031] Preferably, the centers of the first avoidance hole, the second avoidance hole and the camera blind hole 211 are aligned with each other.

[0032] Furthermore, the display module structure further includes a cover plate 300, and the cover plate 300 is connected to the liquid crystal display screen 100 through an optical adhesive 400. The internal structure of the display module is protected by the cover plate 300. Preferably, the cover plate 300 is a glass cover plate.

[0033] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
