[0035] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0036] During the assembly of the backlight assembly, impurities in the atmosphere and impurities on the workers are likely to fall into the backlight film layer of the backlight assembly. Foreign matter in the backlight film layer causes display abnormalities, such as white spots. In the related technology, dust-free cloths are usually used for wiping, vacuum adsorption and other measures for cleaning, but due to technical limitations, it is still impossible to completely remove foreign matter in the backlight film layer, resulting in poor display effects and affecting user experience.

[0037] In order to solve the above problems, the embodiments of the present disclosure provide a backlight bracket, a backlight assembly, a liquid crystal display module and an electronic device. The backlight bracket is applied to the backlight assembly. The backlight bracket includes a bracket body and an adhesive member. The adhesive member is arranged in the bracket body, and the adhesive member is used to adhere to the free foreign matter in the bracket body. In the present disclosure, by arranging the adhesive member in the bracket body, the adhesive member can adhere and fix the free foreign matter in the bracket body, thereby preventing the foreign matter from being in a free state and causing the backlight assembly to display white spots during use, thereby improving the display effect of the backlight assembly.

[0038] According to an exemplary embodiment of the present disclosure, Figure 1 As shown, an embodiment of the present disclosure provides a backlight bracket 10, which is applied to a backlight assembly 100, and is used to support and protect other structures in the backlight assembly 100 (such as a backlight film layer 20, a lighting unit).

[0039] refer to Figures 1 to 4 The backlight bracket 10 includes a bracket body 11, and the bracket body 11 has a certain strength to carry and fix the backlight film layer 20 and the lighting unit and other structures. The bracket body 11 can be formed by injection molding. In one example, the bracket body 11 is made of plastic material, and the bracket body 11 made of plastic can be called a plastic frame. In another example, the bracket body 11 can be made of metal and plastic materials. The use of metal materials can enhance the structural strength of the bracket body 11. The bracket body 11 made of metal and plastic materials is a plastic-iron integrated frame.

[0040] refer to Figure 3 The support body 11 is provided with an adhesive member 12, and the adhesive member 12 is bonded to the support body 11. The bonding connection method can save the need for an additional connection structure in the support body 11, thereby avoiding occupying space in the support body 11 and reducing the weight of the backlight assembly 100.

[0041] Continue to refer Figure 3 The side of the adhesive member 12 that is not connected to the bracket body 11 is also adhesive. In an example, the adhesive member 12 can be a double-sided tape.

[0042] When the backlight film layer 20 is arranged in the accommodating space 111 to be assembled into the backlight component 100, the backlight component 100 can be subjected to a vibration test or a drop test. During the test, foreign matter in the backlight film layer 20 will fall off from the backlight film layer 20 due to vibration or drop impact. The foreign matter after falling off is in a free state. When the foreign matter contacts the adhesive member 12, it will adhere to the adhesive member 12. The display area is not directly opposite to the adhesive member 12, so that the foreign matter adhered to the adhesive member 12 will not cause white spots in the display, thereby improving the display effect.

[0043] In the disclosed embodiment, an adhesive member is provided in the bracket body, so that the adhesive member can adhere to and fix free foreign matter in the bracket body, thereby preventing the foreign matter from being in a free state and causing white spots to appear on the backlight assembly during use, thereby improving the display effect of the backlight assembly.

[0044] In an exemplary embodiment, Figures 1 to 4 As shown, an embodiment of the present disclosure provides a backlight bracket 10, which is applied to a backlight assembly 100. The backlight bracket 10 includes a bracket body 11 and an adhesive member 12. The adhesive member 12 is arranged in the bracket body 11, and the adhesive member 12 is used to adhere to free foreign matter in the bracket body 11.

[0045] In this embodiment, Figures 1 to 4 As shown, the bracket body 11 has a receiving space 111, and the receiving space 111 is formed by a side of the bracket body 11 being recessed inward. Figure 1 and Figure 4 The accommodating space 111 may be a rectangular cavity, for example. The backlight film layer 20 of the backlight assembly 100 may be located in the middle area of ​​the accommodating space 111. The adhesive member 12 for adhering free foreign matter may be arranged around the backlight film layer 20. The adhesive member 12 may be arranged only on the bottom wall or side wall of the accommodating space 111 (not shown in the drawings), or may be arranged at the junction of the bottom wall and the side wall of the accommodating space 111 (see FIG. Figure 3 ).

[0046] In one example, reference Figures 1 to 11 The adhesive member 12 may be a double-sided tape, one adhesive side of the double-sided tape is connected to the bracket body 11 , and the other adhesive side of the double-sided tape faces the area with free foreign matter in the bracket body 11 .

[0047] In another example (not shown in the drawings), the adhesive member can be a single-sided tape, which is bent into a ring shape, and the sticky side of the single-sided tape forms a ring-shaped outer wall. It can be determined that after the single-sided tape is bent into a ring shape, it can be connected to the bracket body and can also adhere to free foreign matter.

[0048] In an exemplary embodiment, Figures 1 to 11 As shown, an embodiment of the present disclosure provides a backlight bracket 10, which is applied to a backlight assembly 100. The backlight bracket 10 includes a bracket body 11 and an adhesive member 12. The adhesive member 12 is arranged in the bracket body 11, and the adhesive member 12 is used to adhere to free foreign matter in the bracket body 11.

[0049] In this embodiment, Figures 5 to 11As shown, a foreign matter receiving groove 112 is provided in the bracket body 11, and the foreign matter receiving groove 112 is connected to the receiving space 111. The foreign matter receiving groove 112 can be formed by a partial structure of the receiving space 111 being recessed inwardly, and at least a partial structure of the adhesive part 12 is connected to the surface of the foreign matter receiving groove 112.

[0050] In one example, reference Figure 5 and Figure 6 , the foreign matter receiving groove 112 is arranged at the junction of the bottom wall and the side wall of the receiving space 111, that is, a groove can be arranged in the contact area between the bottom wall and the side wall of the receiving space 111 to form the foreign matter receiving groove 112. The foreign matter receiving groove 112 is arranged at the junction of the bottom wall and the side wall of the receiving space 111, so that the foreign matter on the bottom wall of the receiving space 111 can slide into the foreign matter receiving groove 112, and at the same time, the foreign matter on the side wall of the receiving space 111 can also be drawn into the foreign matter receiving groove 112, which can enhance the ability of the foreign matter receiving groove 112 to collect foreign matter. In another example, referring to Figure 8 and Fig. 9 The foreign object receiving groove 112 is arranged at the bottom wall edge of the receiving space 111, that is, the foreign object receiving groove 112 is formed by the edge area of ​​the bottom wall of the receiving space 111 being recessed downward, and a side wall of the foreign object receiving groove 112 is parallel to the side wall of the receiving space 111.

[0051] From the above, it can be determined that the reference Figure 7 After the foreign matter falls off from the backlight film layer 20, it can move to the foreign matter receiving groove 112 and adhere to the surface of the adhesive part 12. For the foreign matter that has entered the foreign matter receiving groove 112, multiple angles of the foreign matter have the adhesive part 12. Even if the foreign matter falls off from a certain position of the adhesive part 12, other positions of the adhesive part 12 can adhere and capture the foreign matter again, thereby reducing the possibility of the foreign matter escaping after being adhered and captured, and improving the reliability of adhering and fixing the foreign matter.

[0052] Among them, Figure 5 As shown, the surface of the foreign matter receiving groove 112 is inclined with respect to the bottom wall or the side wall of the receiving space 111. In one example, referring to Figure 5 The surface of the foreign matter receiving groove 112 and the bottom wall of the receiving space 111 have an angle of 15° to 45°. The surface of the foreign matter receiving groove 112 is set to be inclined with the bottom wall of the receiving space 111, so that foreign matter can slide into the foreign matter receiving groove 112. Figure 6 The adhesive member 12 includes a first portion 121 and a second portion 122 that are connected. The first portion 121 is connected to the surface of the foreign matter receiving groove 112, and the second portion 122 is connected to the bottom wall and the side wall of the receiving space 111. It can be determined that the adhesive member 12 has a larger bonding area, so that the connection between the adhesive member 12 and the bracket body 11 is more reliable, and it is also conducive to capturing more free foreign matter.

[0053] Among them, Figure 5 As shown, the bottom wall of the foreign body receiving groove 112 has an arc surface. Taking the adhesive member 12 as a double-sided tape as an example, when the double-sided tape is set in the foreign body receiving groove 112, the position where the double-sided tape is connected to the bottom wall of the foreign body receiving groove 112 needs to be bent to fit the inner wall of the foreign body receiving groove 112. The bottom wall of the foreign body receiving groove 112 is set to an arc surface, so that the bending position of the double-sided tape can smoothly transition and increase the bonding area, which is conducive to improving the bonding reliability between the adhesive member 12 and the foreign body receiving groove 112.

[0054] The foreign body receiving groove 112 has a rough surface. In one example, the surface of the foreign body receiving groove 112 can be frosted to increase the surface roughness of the foreign body receiving groove 112. By setting the surface of the foreign body receiving groove 112 to a rough structure, the bonding effect of the adhesive member 12 can be enhanced to prevent the adhesive member 12 from falling off.

[0055] In some embodiments, Fig.10 As shown, the bottom wall and the side wall of the accommodating space 111 are provided with a step structure 113, and the height of the step structure 113 can be greater than or equal to the thickness of the adhesive member 12 (such as a double-sided tape). Fig.11 It can be determined that the first portion 121 of the adhesive member 12 is located in the foreign matter receiving groove 112, the second portion 122 is located at the lower plane of the step structure 113, the side wall of the second portion 122 of the adhesive member 12 is connected to the vertical surface of the step structure 113, and the top surface of the adhesive member 12 is not higher than the plane where the bottom wall of the receiving space 111 is located. In this embodiment, by providing the step structure 113 on the bottom wall and the side wall of the receiving space 111, the adhesive member 12 no longer protrudes from the bottom wall or the side wall of the receiving space 111, thereby preventing the occurrence of free foreign matter falling on the side of the adhesive member 12.

[0056] According to the embodiment of the present disclosure, Figure 4 and Figure 7 As shown, an embodiment of the present disclosure provides a backlight assembly 100, which includes a backlight film layer 20 and a backlight bracket 10 provided in any of the foregoing embodiments of the present disclosure, wherein the backlight film layer 20 is disposed in the backlight bracket 10, and an adhesive member 12 surrounds the backlight film layer 20.

[0057] refer to Figure 4 and Figure 7In the thickness direction of the backlight bracket 10, the backlight film layer 20 may include a reflective film 21, a light guide plate 22, a diffusion film 23 and a prism film 24. The surface of the light guide plate 22 has a dot distribution, and the illumination light provided by the illumination unit can be converted into a uniform surface light source when passing through the dot. The surface light source is guided out from the upper surface of the light guide plate 22 under the action of the reflective film 21, and then dispersed again by the atomized beads on the surface of the diffusion film 23, while shielding the defects on the surface of the light guide plate 22. Then, the light passes through the prism film 24, and the surface of the prism film 24 has a prismatic structure, which can concentrate the scattered light. It should be noted that, depending on the different lighting units in the backlight assembly 100, the backlight assembly 100 can be divided into edge-entry backlight and direct-down backlight. The edge-entry backlight means that the lighting unit is located on one side of the light guide plate 22, and the lighting direction of the lighting unit is parallel to the top surface of the light guide plate 22. The direct-down backlight means that the lighting unit is located directly below the light guide plate 22, and the lighting direction of the lighting unit is perpendicular to the top surface of the light guide plate 22.

[0058] When the backlight assembly 100 provided with the backlight bracket 10 provided by the embodiment of the present disclosure is assembled and tested, foreign matter lurking in the backlight film layer 20 can fall off from the backlight film layer 20 and be captured by the adhesive member 12, thereby avoiding the appearance of white spots on the display.

[0059] According to the embodiment of the present disclosure, Figure 4 and Figure 7 As shown, an embodiment of the present disclosure provides a liquid crystal display module, which includes a display component and a backlight component 100 provided in the above embodiment of the present disclosure.

[0060] In one example, reference Figure 4 and Figure 7 The display film layer 200 includes a first polarizer 30, a display panel 40, a second polarizer 50, an optical adhesive layer 60 and a protective cover plate 70 from bottom to top. The first polarizer 30 and the second polarizer 50 are used to transmit light having the same polarization direction as the first polarizer 30 and the second polarizer 50, and to block the transmission of light having a polarization direction perpendicular to the first polarizer 30 and the second polarizer 50. The display panel 40 has a liquid crystal structure, which can control the light transmission area and the color of the light. The optical adhesive layer 60 is, for example, OCA (Optical Clear Adhesive), which is a layer of special double-sided adhesive without substrate and optically transparent. The protective cover plate 70 is used to provide protection for the structure below it, and the protective cover plate 70 is made of a transparent material, such as high-strength glass.

[0061] In a liquid crystal display module provided with the backlight assembly 100 provided by the embodiment of the present disclosure, foreign matter lurking in the backlight film layer 20 can fall off from the backlight film layer 20 and be captured by the adhesive member 12, thereby avoiding the appearance of white spots on the display.
