Description

Technical Field

[0001] The utility model relates to the technical field of display modules, in particular to an integrated display module capable of preventing light leakage from a camera hole. Background Art

[0002] In electronic devices such as mobile phones and tablets, the camera is usually integrated into the display module. That is, a camera hole is dug in the middle of the display module and the camera is installed in the camera hole. Usually, in order to prevent light leakage from the camera hole, it is necessary to perform glue dispensing operations on the edge area of ​​the camera hole. Generally, the glue dispensing process requires two steps, that is, the glue needs to be dispensed twice. However, since the glue is liquid and has fluidity, and the size of the camera hole is small, it is easy to make the glue dispensing amount difficult to control, and there is also the risk of contaminating other components due to improper glue dispensing. Therefore, the general glue dispensing process is relatively complicated, which can easily lead to low production efficiency and production yield.

[0003] In view of the above, an integrated display module for preventing light leakage through a camera hole is proposed, which replaces the existing structure for shielding light by dispensing glue, so as to prevent light leakage through the camera hole. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide an integrated display module that prevents light leakage through a camera hole, replacing the existing structure that shields light by dispensing glue to prevent light leakage through the camera hole.

[0005] The purpose of this utility model is achieved through the following technical solutions:

[0006] An integrated display module for preventing light leakage through a camera hole, comprising: a liquid crystal display and a backlight structure, the liquid crystal display comprising an upper polarizer, CF glass, TFT glass and a lower polarizer stacked in sequence, the lower polarizer being provided with a first camera avoidance hole; the backlight structure being provided on a side of the lower polarizer away from the TFT glass, and the backlight structure being provided with a camera hole, the first camera avoidance hole corresponding to the camera hole; a light-shielding frame being provided around the camera hole on the backlight structure, a light-shielding pad being provided on a side of the light-shielding frame close to the TFT glass; and a light-shielding single-sided adhesive being attached to a side of the light-shielding frame close to the camera hole; and a light-shielding ink layer being provided around the periphery of the camera hole on the TFT glass, the light-shielding ink layer being partially located above the lower polarizer, and the light-shielding ink layer being partially located above the light-shielding pad.

[0007] In one embodiment, a second camera avoidance hole is also provided on the upper polarizer, and the second camera avoidance hole corresponds to the camera hole.

[0008] In one embodiment, the backlight structure includes a backlight frame and an optical component. A limiting cavity is provided on the backlight frame, the optical component is accommodated in the limiting cavity, the camera hole is provided on the backlight frame, and the light shielding frame is arranged on the backlight frame.

[0009] In one embodiment, the light shielding frame and the backlight frame are an integrated rubber-iron frame structure.

[0010] In one embodiment, the shading frame is a black shading plastic frame or a gray shading plastic frame.

[0011] In one embodiment, the light-shielding single-sided adhesive is a black light-shielding single-sided adhesive.

[0012] In one embodiment, the shading pad is a double-sided adhesive shading foam.

[0013] In one embodiment, the light-shielding ink layer is a black light-shielding ink layer.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] The present invention provides an integrated display module that prevents light leakage from a camera hole by providing a light shielding frame around the camera hole in the backlight structure. The light shielding frame prevents the backlight source from leaking from the edge area of ​​the camera hole. Furthermore, to prevent the light source from leaking from the gap between the light shielding frame and the TFT glass, a light shielding pad is provided between the TFT glass and the light shielding frame to fill the gap. Furthermore, since there is a gap between the light shielding pad and the lower polarizer, which would cause the light source to refract from the TFT glass through the gap, a light shielding ink layer is provided in the area around the camera hole on the TFT glass to prevent the light source from refracting from the TFT glass, thereby further preventing light leakage. Furthermore, a light shielding single-sided adhesive is provided on the light shielding frame, and the light shielding single-sided adhesive is used in conjunction with the light shielding frame to further enhance the light leakage prevention effect.

[0018] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the following briefly introduces the drawings required for use in the embodiments.

[0021] In order to facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0022] See also Figure 1 and Figure 2 As shown, an integrated display module with an anti-light leakage hole 210 includes: a liquid crystal display screen 100 and a backlight structure 200, the liquid crystal display screen 100 includes an upper polarizer 110, a CF glass 120, a TFT glass 130 and a lower polarizer 140 stacked in sequence, and a first camera avoidance hole is opened on the lower polarizer 140; the backlight structure 200 is arranged on a side of the lower polarizer 140 away from the TFT glass 130, and the backlight structure 200 is provided with a camera hole 210, and the first camera avoidance hole corresponds to Camera hole 210; a light-shielding frame 220 is arranged on the backlight structure 200 around the camera hole 210, and a light-shielding pad 230 is arranged on the side of the light-shielding frame 220 close to the TFT glass 130; and a light-shielding single-sided adhesive 240 is attached to the side of the light-shielding frame 220 close to the camera hole 210; and a light-shielding ink layer 250 is arranged around the periphery of the camera hole 210 of the TFT glass 130, and the light-shielding ink layer 250 is partially located above the lower polarizer 140, and the light-shielding ink layer 250 is partially located above the light-shielding pad 230.

[0023] It should be noted that, since the polarizing layer of the lower polarizer 140 is not completely transparent, in order to prevent the lower polarizer 140 from affecting the shooting effect of the camera, it is necessary to open a first camera avoidance hole on the lower polarizer 140 to avoid the camera hole 210 through the first camera avoidance hole. Furthermore, in order to prevent the light source from leaking from the edge of the camera hole 210 and the first camera avoidance hole, and at the same time replace the existing structure of shading by dispensing glue, the utility model sets a light shielding frame 220 at the position around the camera hole 210 of the backlight structure 200, and the light shielding frame 220 plays a role in preventing the backlight light source from leaking from the edge area of ​​the camera hole 210; at the same time, due to errors in the production and assembly process of the light shielding frame 220, it is easy to cause a gap between the TFT glass 130 and the light shielding frame 220 after assembly, which will cause the light source to leak from the gap. Therefore, in order to prevent the light source from leaking from the gap between the light shielding frame 220 and the TFT glass 130, a light shielding pad 230 is set between the TFT glass 130 and the light shielding frame 220, and the light shielding pad 230 fills the gap. In addition, after the LCD 100 and the backlight structure 200 are assembled, a certain gap is left between the light shielding pad 230 and the lower polarizer 140 to prevent the light from overlapping. However, this will cause the light to refract from the TFT glass 130 through the gap. Therefore, a light shielding ink layer 250 is provided in the area of ​​the TFT glass 130 surrounding the camera hole 210. The light shielding ink layer 250 prevents the light from refracting from the TFT glass 130, thereby further preventing light leakage. Furthermore, by providing a light shielding single-sided adhesive 240 on the light shielding frame 220, the light shielding single-sided adhesive 240 cooperates with the light shielding frame 220 to further enhance the light leakage prevention effect, that is, to prevent the light from escaping through the light shielding frame. In this way, instead of the existing structure of light shielding by dispensing glue, it can prevent light leakage from the camera hole 210, thereby improving production efficiency and production yield. Furthermore, the integrated display module also includes a cover plate 300.

[0024] Furthermore, the upper polarizer 110 is also provided with a second camera avoidance hole 111, which corresponds to the camera hole 210. The function of the second camera avoidance hole 111 is the same as that of the first camera avoidance hole, both of which are to avoid affecting the camera's shooting effect.

[0025] In one embodiment, the backlight structure 200 includes a backlight frame 260 and an optical assembly 270. The backlight frame 260 defines a limiting cavity, within which the optical assembly 270 is housed. Furthermore, the camera aperture 210 is defined in the backlight frame 260, and the light shielding frame 220 is disposed on the backlight frame 260. The optical assembly 270 improves the brightness and uniformity of the backlight source, thereby enhancing the display effect.

[0026] Preferably, the light shielding frame 220 and the backlight frame 260 are an integrated plastic-iron structure. That is, the light shielding frame 220 and the backlight frame 260 are integrally molded using corresponding molds, thereby enhancing the overall strength of the light shielding frame 220 and the backlight frame 260. Preferably, the light shielding frame 220 is a black or gray light shielding plastic frame, as dark colors such as black or gray provide the best light shielding effect. At the same time, since the light-shielding frame 220 is relatively thin and there is still a risk of light transmission, adding a light-shielding single-sided adhesive 240 to the light-shielding frame 220 can further improve the light-shielding effect. In this embodiment, the light-shielding single-sided adhesive 240 is a black light-shielding single-sided adhesive 240. Furthermore, the light-shielding single-sided adhesive 240 is partially attached to the side surface of the light-shielding frame 220 facing the TFT glass 130, and partially attached to the side surface of the light-shielding frame 220 facing the camera hole 210. In this way, the attachment area of ​​the light-shielding single-sided adhesive 240 can be increased to avoid the risk of the light-shielding single-sided adhesive 240 falling off.

[0027] Preferably, the light shielding pad 230 is a light shielding foam double-sided adhesive. That is, the light shielding pad 230 uses black foam double-sided adhesive, with one side of the black foam double-sided adhesive attached to the TFT glass 130 and the other side attached to the light shielding frame 220 to fill the gap between the TFT glass 130 and the light shielding frame 220. The double-sided adhesive of the foam structure can also act as a buffer for the TFT glass 130, preventing the backlight frame 260 and the light shielding frame 220 from causing damage to the TFT glass during collisions.

[0028] Preferably, the light-shielding ink layer 250 is black. Black has the best light-shielding effect, thus preventing light from passing through the gap between the upper polarizer 110 and the light-shielding pad 230 and being refracted out of the TFT glass 130. This further improves the light leakage prevention effect of the camera hole 210.

[0029] In one embodiment, the backlight frame 260 is provided with a bent support portion 261 around the periphery of the camera hole 210, and the light shielding frame 220 is disposed on the bent support portion 261. The free end of the bent support portion 261 is bent and tilted toward the LCD display 100, forming a supporting structure. The bent support portion 261 supports the light shielding frame 220, which not only improves the strength of the light shielding frame 220 but also increases the area of ​​the light shielding frame 220 facing the TFT glass 130, thereby increasing the attachment area of ​​the light shielding pad 230 and ensuring a secure attachment.

[0030] Specifically, the optical assembly 270 includes a stacked brightness enhancement film 271, a diffusion film 272, a light guide plate 273, and a reflective film 274. The optical components can improve the brightness and uniformity of the backlight source, thereby enhancing the display effect.

[0031] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
