Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application. In addition, it should be understood that the specific implementation manners described herein are only used to illustrate and explain the present application, and are not used to limit the present application. In the present application, the embodiments can be combined with each other without further elaboration, and in the case of no contrary description, the orientation terms such as "upper" and "lower" usually refer to the upper and lower in the actual use or working state of the device, specifically the drawing direction in the drawings; and "inner" and "outer" are relative to the contour of the device; the terms "first", "second", "third", etc. are only used as labels, and no digital requirements are imposed or an order is established.

[0045] Embodiments of the present application provide a backlight module, a display module, and a display device, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments.

[0046] Please refer to Figures 1 to 2 , embodiments of the present application provide a display module p1, which includes a backlight module 100 and a display panel 200 disposed on the light-emitting side of the backlight module 100.

[0047] Optionally, the display panel 200 is a liquid crystal display panel.

[0048] Please refer to Figures 1 to 4 , the backlight module 100 includes a light guide plate 10 and an appearance structure layer 20.

[0049] The light guide plate 10 includes a peripheral side surface 11 and a first surface 12 and a second surface 13 that are oppositely disposed. In the thickness direction of the light guide plate 10, the peripheral side surface 11 is connected between the first surface 12 and the second surface 13. The first surface 12 includes a light-emitting surface 12a and a non-light-emitting surface 12b, and the non-light-emitting surface 12b surrounds the periphery of the light-emitting surface 12a. The peripheral side surface 11 includes a light-incident surface 11a and a non-light-incident surface 11b. The light-incident surface 11a is configured to transmit light into the interior of the light guide plate 10. The appearance structure layer 20 covers the non-light-emitting surface 12b, the non-light-incident surface 11b, and the second surface 13 of the light guide plate 10.

[0050] Among them, the appearance structure layer 20 includes an appearance layer 21 and a reflection layer 22, and the appearance layer 21 covers the side of the reflection layer 22 away from the light guide plate 10.

[0051] It can be understood that the backlight module 100 of the display module p1 in the embodiment of the present application uses the appearance structure layer 20 to cover the non-light-emitting surface 12b, the non-light-incident surface 11b, and the second surface 13 of the light guide plate 10 as the appearance structure, so that the conventional appearance outer frame can be saved in the display device; secondly, the backlight module 100 of the display module p1 in the embodiment of the present application also saves the conventional backplane and rubber frame, simplifying the backlight module 100; therefore, in this embodiment, by saving the conventional appearance outer frame, backplane and rubber frame, the structure is simplified, the backlight module 100 is thinned, and the assembly steps are reduced, greatly improving the assembly efficiency. In addition, the reflective layer 22 is integrated into the appearance structure layer, which can simplify the structure of the module and reduce the thickness of the backlight module.

[0052] Optionally, both the appearance layer 21 and the reflective layer 22 at least entirely cover the non-light-emitting surface 12b, the non-light-incident surface 11b, and the second surface 13 of the light guide plate 10.

[0053] Optionally, in some embodiments of the present application, the appearance structure layer 20 does not cover the light-incident surface 11a of the light guide plate 10.

[0054] Optionally, in some embodiments of the present application, the appearance structure layer 20 also covers a part of the light-incident surface 11a of the light guide plate 10. That is, a plurality of hollow openings are formed in a part of the appearance structure layer 20 on the light-incident surface 11a, and each hollow opening is configured to transmit the light emitted by the light-emitting device. The appearance structure layer 20 is provided between two adjacent hollow openings to improve the light utilization rate.

[0055] Optionally, in some embodiments of the present application, a groove is further provided in the area of the light guide plate 10 corresponding to the hollow opening, and the groove is configured to accommodate the light-emitting device to improve the light utilization rate.

[0056] Optionally, in some embodiments of the present application, the hardness of the appearance layer 21 is greater than the hardness of the reflective layer 22.

[0057] It can be understood that the appearance layer 21 is arranged on the outermost of the backlight module 100 and the display device. Therefore, the appearance layer 21 has a greater hardness, which can play the roles of wear resistance, scratch resistance, and protection of the reflective layer 22.

[0058] Optionally, the material of the reflective layer 22 is not specifically limited as long as it can reflect light. The color of the appearance layer 21 can be selected according to actual needs, and the present application does not limit it, such as black.

[0059] Optionally, in some embodiments of the present application, both the reflective layer 22 and the appearance layer 21 are coatings.

[0060] It can be understood that, compared with the method of fixing the appearance layer 21 and the reflective layer 22 by gluing, both the reflective layer 22 and the appearance layer 21 are coatings, which can further thin the backlight module 100. Moreover, the double - coating setting avoids the light leakage caused by the attachment error and the different thermal expansion coefficients of the adhesive layer and the light guide plate 10.

[0061] Optionally, the absolute value of the difference between the thermal expansion coefficient of the reflective layer 22 and the thermal expansion coefficient of the light guide plate 10 is less than 10 ppm / °C to reduce the risk of peeling between the two due to thermal expansion.

[0062] Optionally, in some embodiments of the present application, one side of the reflective layer 22 is covalently bonded to the light guide plate 10, and the other side of the reflective layer 22 is also covalently bonded to the appearance layer 21 to improve the bonding strength between the light guide plate 10 and the appearance layer 21 and the reflective layer 22 respectively, thereby reducing the risk of peeling due to different thermal expansion coefficients.

[0063] Optionally, in some embodiments of the present application, the backlight module 100 includes an optical film 30, and the optical film 30 is disposed on the light - emitting surface 12a of the light guide plate 10. The edge portion of the optical film 30 overlaps with the appearance structure layer 20.

[0064] It can be understood that the edge portion of the optical film 30 overlaps with the appearance structure layer 20 to ensure that the light emitted from the light - emitting surface 12a of the light guide plate 10 will penetrate the optical film 30.

[0065] Optionally, the optical film 30 is attached to the light guide plate 10 by gluing.

[0066] Please refer to Figure 1 and Figure 2 Optionally, in some embodiments of the present application, the display module p1 includes a first circuit board 401 and a second circuit board 402. One end of the first circuit board 401 is connected to the display panel 200, and the other end of the first circuit board 401 is connected to the second circuit board 402. The second circuit board 402 is disposed in the area of the appearance structure layer 20 corresponding to the non - light - emitting surface 12b of the light guide plate 10.

[0067] The part of the light guide plate 10 located on the non - light - emitting surface 12b supports the second circuit board 402.

[0068] It can be understood that one end of the light guide plate 10 corresponding to the first circuit board 401 and the second circuit board 402 is extended to support the first circuit board 401 and the second circuit board 402, without the need to additionally provide a bracket to support and fix the first circuit board 401 and the second circuit board 402.

[0069] Optionally, in some embodiments of the present application, the second circuit board 402 is fixed to the appearance structure layer 20 through an adhesive layer 403.

[0070] It can be understood that, compared with the way of using threaded connection for the support tongues of the circuit board and the backplane in a conventional display, the embodiment of the present application adopts the inner adhesive layer 403, which can reduce the risk of abnormal noise.

[0071] Optionally, in some embodiments of the present application, the thermal conductivity of the appearance layer 21 is lower than the thermal conductivities of the reflective layer 22 and the light guide plate 10. That is to say, the heat insulation effect of the appearance layer 21 is relatively good, which can reduce the influence of heat on the adhesive layer 403, and improve the fixing firmness of the second circuit board 402 and the appearance structure layer 20.

[0072] Optionally, the first circuit board 401 is a flexible circuit board or a chip on film, and the second circuit board 402 is a rigid circuit board, such as a printed circuit board.

[0073] Optionally, in some embodiments of the present application, the display module p1 includes a light-shielding adhesive 404, and the light-shielding adhesive 404 is located on the outer peripheral side of the optical film of the backlight module 100. The light-shielding adhesive 404 is disposed on the area of the appearance structure layer 20 corresponding to the non-light-emitting surface 12b of the light guide plate 10. The display panel 200 is connected and disposed on the side of the light-shielding adhesive 404 away from the light guide plate 10. There is a gap between the optical film 30 and the light-shielding adhesive 404.

[0074] It can be understood that using the light-shielding adhesive 404 to connect the display panel 200 and the backlight module 100 can reduce the risk of light leakage. Secondly, there is a gap between the optical film 30 and the light-shielding adhesive 404, which can meet the space requirement for the thermal expansion of the optical film 30 and play a role in limiting the optical film 30.

[0075] Optionally, the gap width between the optical film 30 and the light-shielding adhesive 404 is between 0.2 mm and 0.6 mm, and can be, for example, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm or 0.6 mm.

[0080] The control module 300 includes a housing 31 and a control component 32, and the control component 32 is disposed within the housing 31. A portion of the housing 31 that extends beyond the control component 32 forms a slot 31a, and a portion of the display module p1 is inserted into the slot 31a. The control component 32 is configured to control the display of the display module p1.

[0081] It can be understood that, based on integrating the appearance structure of the display device 1000 into the backlight module 100, that is, using the appearance layer 21 to replace the appearance outer frame of a conventional display, thereby saving the steps of assembling the appearance outer frame and reducing the thickness of the display device 1000 at the same time.

[0082] Secondly, the connection and cooperation of the display module p1 and the control module 300 simplifies the assembly steps of a conventional display and improves the assembly efficiency of the display device 1000.

[0083] In addition, in some embodiments of the present application, the control module 300 is further configured to serve as a base to support and fix the display module p1, so that there is no need to additionally provide a base to support the display module p1.
