The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0036] Hereinafter, an illumination display device 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0037] like Figure 1 As shown, the lighting display device 100 includes a backlight assembly 1 and a display assembly 2. The backlight assembly 1 includes a back plate 11 and a light source 12. The light source 12 is arranged on the front side of the back plate 11. The back plate 11 is a transparent member so that the light of the light source 12 can be emitted through the back plate 11. Then, the light emitted through the back plate 11 can be used for lighting, so that the lighting display device 100 has a lighting function. The display assembly 2 includes a display panel 21. The display panel 21 is arranged on a side of the light source 12 away from the back plate 11. The light of the light source 12 can be emitted toward the display panel 21. Then, the display panel 21 can be used to display an image, so that the lighting display device 100 has a display function.

[0038] The direction “front side of the back panel 11” can be understood as one side of the thickness of the back panel 11, and the opposite direction is defined as “back side of the back panel 11”. “Back side of the back panel 11” can be understood as the other side of the thickness of the back panel 11. When the user is viewing the displayed image on the lighting display device 100, the side of the back panel 11 closer to the user is the front side of the back panel 11; for example, Figure 1 In the example of , “the front side of the back plate 11 ” may refer to the upper side of the back plate 11 , and “the back side of the back plate 11 ” may refer to the lower side of the back plate 11 .

[0039] It is understandable that, since the back plate 11 is a transparent member, the lighting display device 100 can emit light on the back side of the back plate 11 for lighting, provided that the lighting display device 100 can achieve normal display on the front side of the back plate 11 .

[0040] Therefore, according to the lighting display device 100 of the embodiment of the present invention, by setting the back panel 11 as a transparent part, the lighting display device 100 can have both lighting function and display function, and the lighting function will not affect the display effect of the lighting display device 100, thereby enriching the functions of the lighting display device 100 and helping to improve the applicability of the lighting display device 100. For example, the lighting display device 100 can be used in scenes where lighting is required at night in addition to information indication during the day, so as to achieve good publicity effects.

[0041] Optionally, the back plate 11 may be made of an optically transparent material, such as PC (polycarbonate), PMMA (polymethyl methacrylate) or resin.

[0042] In some embodiments, Figure 1As shown, the backlight assembly 1 also includes an outer frame 13, which is arranged in the non-display area of ​​the display panel 21, and the outer frame 13 extends along the edge of the back plate 11 to form a ring structure. A first reflector 14 is provided on the inner circumferential surface of the outer frame 13. The first reflector 14 can reflect the light from the light source 12, thereby optimizing the display quality at the edge of the display panel 21, which is beneficial to improving the display effect of the lighting display device 100.

[0043] Optionally, the first reflective element 14 may be made of white paint or white reflective sticker, etc., to ensure that the first reflective element 14 can reflect light.

[0044] Optionally, the outer frame 13 is formed as an aluminum extrusion.

[0045] In some embodiments, Figure 1 As shown, a housing cavity 131 is defined in the outer frame 13, and the battery assembly 3 of the lighting display device 100 is arranged in the housing cavity 131. The battery assembly 3 is electrically connected to the light source 12 to supply power to the light source 12. By arranging the battery assembly 3, the lighting display device 100 can realize its own power supply, so that the lighting display device 100 can be used normally without external other power supply equipment, which is beneficial to improving the use convenience of the lighting display device 100; at the same time, the battery assembly 3 is arranged in the housing cavity 131 of the outer frame 13, and the battery assembly 3 does not need to occupy additional installation space, so the compact structure design of the lighting display device 100 can be realized, the occupied space of the lighting display device 100 is saved, and it is beneficial to improve the applicability of the lighting display device 100. For example, the lighting display device 100 can be suitable for scenes with requirements on layout space.

[0046] It is understandable that there can be one or more battery assemblies 3; when there are multiple battery assemblies 3, the multiple battery assemblies 3 can be arranged along the circumference of the outer frame 13, which is beneficial to improving the endurance of the lighting display device 100 and achieving long-term operation.

[0047] Optionally, in Figure 3 In the example, the battery assembly 3 is a rechargeable battery, for example, the battery assembly 3 is a storage battery, and a charge and discharge controller 4 is provided between the rechargeable battery and the light source 12. Then, the battery assembly 3 can supply power to the light source 12 through the charge and discharge controller 4, and the battery assembly 3 is discharged at this time, and the charge and discharge controller 4 can also be connected to an external power supply to realize the charging of the battery assembly 3. Thus, it is beneficial to improve the convenience of use and service life of the lighting display device 100.

[0048] For example, a through hole can be opened on the outer frame 13, and the battery assembly 3 is electrically connected to the input end of the charge and discharge controller 4 through a wire passing through the through hole. Then, the charging end of the charge and discharge controller 4 is connected to the battery assembly 3, and the output end of the charge and discharge controller 4 can be electrically connected to the light source 12 through a DC output socket.

[0049] In some embodiments, Figure 2 As shown, a light shielding layer 5 is provided on the back surface of the back plate 11, and the light shielding layer 5 exposes a part of the surface of the back plate 11, so that the setting of the light shielding layer 5 does not affect the lighting function of the lighting display device 100. At the same time, the shape of the light shielding layer 5 can be set so that the light shielding layer 5 does not block a part of the back plate 11 to form a certain pattern, thereby realizing patterned lighting, so that the lighting display device 100 can be patterned and customized, and the mirror function of the back side of the lighting display device 100 can be realized, which can be widely used in outdoor advertising, public commercial display, bus stop signs and other application scenarios. Among them, the pattern should be understood in a broad sense, and can be text, pictures, LOGO, etc.

[0050] Optionally, in Figure 2 In the example of , the light shielding layer 5 is a metal layer to ensure the light shielding effect of the light shielding layer 5. The metal layer can be selected as a high reflectivity metal piece; the metal layer can be provided on the back surface of the back plate 11 by evaporation or deposition.

[0051] In some embodiments, Figure 1 As shown, the light source 12 includes a substrate 121, a plurality of LED lamps 122 and a connector 123. In this case, the display panel 21 can be an LCD display panel. The substrate 121 is arranged on the front side surface of the back plate 11. The substrate 121 is a transparent member. The plurality of LED lamps 122 are arranged on the side of the substrate 121 away from the back plate 11. For example, the plurality of LED lamps 122 are all arranged on the surface of the substrate 121, and the plurality of LED lamps 122 can be arranged in an array. The connector 123 is electrically connected to the plurality of LED lamps 122. Then, the external power supply 101 or the battery assembly 3 of the lighting display device 100 can be connected to the connector 123 to supply power to the plurality of LED lamps 122, so that the plurality of LED lamps 122 emit light, thereby facilitating the power supply connection of the light source 12.

[0052] Optionally, in Figure 1 In the example, a through hole is formed on the outer frame 13 of the backlight assembly 1, and the connector 123 can be electrically connected to the battery assembly 3 arranged in the outer frame 13 through a wire passing through the through hole.

[0053] Optionally, the substrate 121 is a glass member; but not limited thereto.

[0054] In some embodiments, Figure 1 and Figure 2 As shown, an optical film 125 may be provided on the front side surface of the substrate 121 , and the optical film 125 may reflect and / or transmit the light of the light source 12 to improve the display utilization rate of the light source 12 .

[0055] It is understandable that the optical film 125 can be selected according to specific usage scenarios and requirements. When the lighting display device 100 has a high display brightness requirement and a low back lighting brightness requirement, the optical film 125 can use a high reflectivity reflective film; when the lighting display device 100 has a substantially balanced display brightness requirement and a back lighting brightness requirement, the optical film 125 can be a semi-transparent and semi-reflective film layer; when the lighting display device 100 has a low display brightness requirement and a high back lighting brightness requirement, the optical film 125 can be an anti-reflective film.

[0056] In some embodiments, Figure 1 As shown, the connector 123 is disposed on a side surface of the substrate 121 away from the back plate 11, so as to facilitate electrical connection between the connector 123 and the plurality of LED lamps 122. Among them, a second reflector 124 is disposed on a side surface of the connector 123 away from the substrate 121, and the second reflector 124 can reflect the light of the light source 12, so as to prevent the connector 123 from absorbing the light of the LED lamp 122 and causing a dark shadow on the display panel 21, thereby ensuring the display effect of the lighting display device 100.

[0057] Optionally, the second reflective member 124 is a reflective sticker or the like to ensure the first reflective member 14 can reflect light.

[0058] Of course, the present application is not limited to this; in other embodiments, a receiving space is formed on the back panel 11, and the connector 123 is disposed in the receiving space, so that the arrangement of the connector 123 will not affect the display effect of the display panel 21 due to absorbing light.

[0059] Optionally, a groove may be formed on the back plate 11 , and the groove may be formed by recessing one side of the front side surface of the back plate 11 to define a receiving space.

[0060] In some embodiments, Figure 1-Figure 3 As shown, the lighting display device 100 also includes a solar power generation component 6, which is arranged on the side of the backlight component 1 away from the display component 2, and the solar power generation component 6 is electrically connected to the battery component 3 of the lighting display device 100 through the charge and discharge controller 4. The solar power generation component 6 can charge the battery component 3 through the charge and discharge controller 4 to ensure the battery life of the battery component 3, which is conducive to realizing the long-term operation of the lighting display device 100. At the same time, the lighting display device 100 does not need to be connected to other external power supply equipment, which is convenient for breaking the restrictions of the external power supply equipment on the position of the lighting display device 100, thereby improving the applicability of the lighting display device 100.

[0061] Of course, if Figure 3As shown, the battery assembly 3 can also be electrically connected to the external power source 101. For example, in order to cope with the problem of insufficient converted power caused by the uncertainty of external ambient light, the battery assembly 3 can be electrically connected to the external power source 101.

[0062] In some embodiments, Figure 1 and Figure 2 As shown, the solar power generation component 6 includes a solar panel 61, which is arranged on the back side of the back plate 11, and the solar panel 61 is electrically connected to the charge and discharge controller 4.

The solar power generation component 6 also includes a protective plate 62, which is arranged on the side of the solar panel 61 away from the back plate 11, and the solar panel 61 is arranged on the inner side of the protective plate 62. The protective plate 62 can play a certain protective role on the solar panel 61. The edge of the protective plate 62 extends to the outside of the solar panel 61, and the protective plate 62 is fixedly connected to the edge of the back plate 11 component, so as to facilitate the installation of the solar power generation component 6, and the installation of the solar power generation component 6 will not affect the solar panel 61.

[0063] Optionally, the solar cell panel 61 may be a transparent photovoltaic device made of halide perovskite material.

[0064] Optionally, in Figure 2 In the example, a shading layer 5 is provided on the back surface of the back plate 11, and the shading layer 5 exposes a portion of the surface of the back plate 11, so that the setting of the shading layer 5 does not affect the lighting function of the lighting display device 100, and the shading layer 5 can reflect light to secondary reflect ambient light, which can increase the absorption and conversion effect of the solar cell panel 61 on the external ambient light source.

[0065] In some embodiments, Figure 1 As shown, the backlight assembly 1 further includes an outer frame 13, which is disposed in the non-display area of ​​the display panel 21, and extends along the edge of the back plate 11 to form an annular structure, and an end of the outer frame 13 away from the display assembly 2 is formed with a receiving groove 132, and the edge of the protective plate 62 is matched with the receiving groove 132, so as to ensure the assembly accuracy of the solar power generation assembly 6 and the back plate 11 assembly, and at the same time, it is beneficial to reduce the thickness of the lighting display device 100. Among them, the edge of the protective plate 62 is bonded to the outer frame 13, so that the solar power generation assembly 6 is easy and reliable to install.

[0066] It can be understood that the protection plate 62 can be a transparent member or a non-transparent member such as a light-shielding member.

[0067] Optionally, the protection plate 62 is ultra-white tempered glass, and the protection plate 62 has good light transmittance and structural strength, ensuring that the protection plate 62 effectively protects the solar cell panel 61 and at the same time ensures that more ambient light passes through the protection plate 62 to irradiate the solar cell panel 61.

[0068] For example, Figure 1 As shown, the display assembly 2 further includes a diffuser 22, which is disposed between the display panel 21 and the backlight assembly 1, the edge of the front side of the diffuser 22 is bonded to the display panel 21, and the edge of the back side of the diffuser 22 is bonded to the backlight assembly 1, for example, the front side of the edge of the diffuser 22 is bonded to the display panel 21 through a glue piece 100a, and the back side of the edge of the diffuser 22 is connected to the outer frame 13 of the backlight assembly 1 through a glue piece 100a; the display assembly 2 further includes an IC circuit 23, which includes a COF and a PCB board, a receiving cavity 131 is formed on the outer frame 13 of the backlight assembly 1, an opening is formed on one side of the receiving cavity 131, a cover 8 is provided at the opening, the cover 8 covers the opening, and a communication port communicating with the receiving cavity 131 is defined between the cover 8 and the outer frame 13, and the IC circuit 23 is disposed in the receiving cavity 131 and is connected to the display panel 21 through the communication port. Among them, the coating of the glue can be realized by using an automated device.

[0069] The shape of the accommodating cavity 131 can be specifically determined according to the avoidance condition of the PCB board of the IC circuit 23 and the size parameters of the battery assembly 3 .
