[0036] Embodiment 1

[0037] like Figures 1 to 3 As shown, the present application provides a double-sided display module, including a light source assembly 10 and two display panels 20, the light source assembly 10 includes a substrate 110, and a first light-emitting element 120 and a second light-emitting element 130 arranged on the substrate 110, the substrate 110 can allow light to pass through, the light source assembly 10 has a first light-emitting side and a second light-emitting side relative to each other, the first light-emitting element 120 is located on the first light-emitting side, and the second light-emitting element 130 is located on the second light-emitting side; one of the two display panels 20 is located on the first light-emitting side, and the other display panel 20 is located on the second light-emitting side.

[0038] The double-sided display module provided by the present application is provided with a first light-emitting element 120 and a second light-emitting element 130 on a substrate 110 through which light can pass, so that the light output on the first light-emitting side of the light source assembly 10 includes not only the direct light emitted by the first light-emitting element 120 located on the first light-emitting side, but also the indirect light emitted by the second light-emitting element 130 located on the second light-emitting side after passing through the substrate 110, and the light output on the second light-emitting side includes not only the direct light emitted by the second light-emitting element 130 located on the second light-emitting side, but also the indirect light emitted by the first light-emitting element 120 located on the first light-emitting side after passing through the substrate 110, so that the light output along the two light-emitting sides of the light source assembly 10 is relatively large, which is conducive to improving the display effect. The two display panels 20 are respectively provided on the two light-emitting sides of the light source assembly 10, and the two display panels 20 share one light source assembly 10 to form a double-sided display module, so that not only the purpose of integrated double-sided display is achieved, but also the structure of the double-sided display module is optimized. In addition, such a design omits the supporting parts in the related art, which optimizes the structure of the double-sided display module and reduces the thickness on the one hand, and reduces the cost on the other hand.

[0039] The first light-emitting side and the second light-emitting side can be determined according to the shape of the substrate 110 and actual requirements. Here, the substrate 110 is in a plate shape as an example for explanation, but the substrate 110 is not limited to a plate shape. When the substrate 110 is in a plate shape, the first light-emitting side and the second light-emitting side can be two sides along the thickness direction of the substrate 110, that is, the two display panels 20 are arranged back to back on two sides of the substrate 110 along the thickness direction thereof.

[0040] like Figure 1 As shown, in some embodiments, the substrate 110 is a glass substrate, and the first light-emitting side and the second light-emitting side are two sides of the substrate 110 along the thickness direction.

[0041] Since glass has the characteristics of high refractive index, certain hardness and low cost, by designing the base 110 into a glass substrate structure, the base 110 can not only play the role of carrying the first light-emitting element 120 and the second light-emitting element 130, so that the light source assembly 10 is not easy to deform, and has good light transmittance and low manufacturing cost. In addition, the first light-emitting side and the second light-emitting side are the two sides of the base 110 along the thickness direction, so that the base 110 can maximize the use of the surface of the base 110 to set the first light-emitting element 120 and the second light-emitting element 130 on the basis of ensuring the bearing thickness, thereby facilitating the control of the thickness of the light source assembly 10 along the thickness direction of the base 110.

[0042] For example, Figure 2 As shown, the substrate 110 is a glass substrate, and the first light emitting element 120 and the second light emitting element 130 are arranged on two opposite sides of the substrate 110 along the thickness direction. Figure 3As shown, in some embodiments, the first light emitting element 120 and the second light emitting element 130 may be the same, including the first light emitting element 120 and the second light emitting element 130 may have the same serial number, quantity and arrangement on the substrate 110, so that the same brightness of double-sided display can be achieved. Alternatively, the first light emitting element 120 and the second light emitting element 130 may select different light emitting elements according to the double-sided display requirements, that is, the first light emitting element 120 and the second light emitting element 130 are different, and the difference here may be at least one of the different models, quantities and arrangements on the substrate 110, which are not specifically limited here.

[0043] like Figure 2 As shown, in some embodiments, a first reflective layer 151 is disposed on one side of the substrate 110 where the first light emitting element 120 is disposed. That is, the first reflective layer 151 is disposed on a surface of the substrate 110 close to the first light emitting side.

[0044] Through the above arrangement, part of the light emitted by the first light-emitting element 120 is directly transmitted to the first light-emitting side, and the other part of the light is also transmitted along the first light-emitting side after being reflected by the first reflective layer 151, thereby improving the light-emitting efficiency of the first light-emitting element 120.

[0045] like Figure 1 and Figure 2 As shown, in some embodiments, a first reflective layer 151 is disposed on a side of the substrate 110 where the first light emitting element 120 is disposed, and a second reflective layer 152 is disposed on a side of the substrate 110 where the second light emitting element 130 is disposed.

[0046] Through the above arrangement, not only a part of the light emitted by the first light-emitting element 120 is directly transmitted to the first light-emitting side, and another part of the light is also transmitted along the first light-emitting side after being reflected by the first reflective layer 151, but also a part of the light emitted by the second light-emitting element 130 is directly transmitted to the second light-emitting side, and another part of the light is also transmitted along the second light-emitting side after being reflected by the second reflective layer 152. In this way, not only the overall light-emitting efficiency of the light source assembly 10 is improved, but also the light output amounts of the first light-emitting side and the second light-emitting side of the light source assembly 10 are made symmetrical.

[0047] In addition, as needed, the second reflective layer 152 can be provided only on one side of the substrate 110 where the second light-emitting element 130 is provided, without providing the first reflective layer 151, so that the light output on the first light-emitting side and the second light-emitting side of the light source assembly 10 is different to adapt to different scenarios.

[0048] like Figure 1As shown in the figure, in some embodiments, the double-sided display module also includes a light source driving circuit 140, the light source driving circuit 140 is electrically connected to the first light-emitting element 120, and the light source driving circuit 140 is electrically connected to the second light-emitting element 130, and the light source driving circuit 140 is located at the edge of the substrate 110.

[0049] By arranging the light source driving circuit 140 at the edge of the substrate 110 , the influence on the first light emitting element 120 and the second light emitting element 130 is reduced, thereby facilitating improving the display effect.

[0050] The light source driving circuit 140 may be disposed at the edge of the first light emitting side of the substrate 110 , or at the edge of the second light emitting side, or on the side wall of the substrate 110 between the first light emitting side and the second light emitting side, without specific limitation herein.

[0051] like Figure 1 As shown, in some embodiments, the light source driving circuit 140 includes a first driving circuit 141 and a second driving circuit 142, the first light-emitting element 120 and the first driving circuit 141 are arranged on the same side of the substrate 110 and the first light-emitting element 120 is electrically connected to the first driving circuit 141, and the second light-emitting element 130 and the second driving circuit 142 are arranged on the same side of the substrate 110 and the second light-emitting element 130 is electrically connected to the second driving circuit 142.

[0052] The first driving circuit 141 and the first light-emitting element 120 are arranged on the same side of the substrate 110, and the second driving circuit 142 and the second light-emitting element 130 are arranged on the same side of the substrate 110. In this way, it is not only convenient to electrically connect the light source driving circuit 140 with the first light-emitting element 120 and the second light-emitting element 130, but also, compared with setting a driving circuit on one side edge of the substrate 110, it is possible to realize the electrical connection between the light source driving circuit 140 and the first light-emitting element 120 and the second light-emitting element 130 without performing a process of punching holes on the substrate 110 for electrical connection, or, compared with setting the light source driving circuit 140 on the side wall between the first light-emitting side and the second light-emitting side of the substrate 110, the occupied space of the light source assembly 10 in the direction perpendicular to the thickness direction is reduced, thereby facilitating the reduction of the width of the non-display area of ​​the double-sided display module. In addition, the light emission of the first light-emitting element 120 and the second light-emitting element 130 can be controlled separately, so that the light source assembly 10 has two modes: synchronous display and asynchronous display.

[0053] The preparation process of the light source assembly 10 is described by taking the substrate 110 as a glass substrate as an example. The material and structure of the substrate 110 are not limited to glass substrates. The preparation process of the light source assembly 10 in the first embodiment is as follows:

[0054] Step 1: First, design the circuit of the first driving circuit 141 on one side surface of the substrate 110;

[0055] Step 2: forming a conducting circuit, namely the first driving circuit 141, through timing, exposure and development, and determining the first installation position area of ​​the first light-emitting element 120;

[0056] Step 3: Use the steel mesh to brush tin on the first installation position area;

[0057] Step 4: Binding the first light emitting element 120 to the first installation position area by binding, so that the first light emitting element 120 is electrically connected to the first driving circuit 141;

[0058] Step 5: Then, the first reflective layer 151 is coated on the surface where the first light emitting element 120 is disposed through a steel mesh;

[0059] Step 6: Designing the second driving circuit 142 and the second light-emitting element 130 on the other side of the substrate 110 , the process is the same as the process of designing the first driving circuit 141 and the second light-emitting element 130 on the substrate 110 .

[0060] Of course, the first driving circuit 141 and the second driving circuit 142 can also be formed simultaneously on the substrate 110 by double-sided etching, exposure, and development, and then the first light-emitting element 120 and the second light-emitting element 130 can be designed on the first driving circuit 141 respectively, which is not specifically limited here.

[0061] like Figure 1 As shown, in some embodiments, the display panel 20 includes a color filter substrate 210 , a liquid crystal layer 220 and an array substrate 230 . The array substrate 230 includes a third glass substrate 231 . A diffusion plate 170 is provided between the third glass substrate 231 and the light source assembly 10 .

[0062] By providing a diffusion plate 170 between the third glass substrate 231 and the light source assembly 10 , the light emitted by the light source assembly 10 is more evenly dispersed after passing through the diffusion plate 170 , thereby facilitating improving the display effect.

[0063] The diffuser 170 uses chemical or physical means to utilize the physical phenomena of refraction, reflection and scattering when light encounters two media with different refractive indices during its path. By adding inorganic or organic light diffusers to the substrate, or by arranging an array of micro-feature structures on the surface of the substrate, the light is artificially adjusted to cause the light to refract, reflect and scatter in different directions, thereby changing the path of the light and achieving sufficient dispersion of the incident light to produce an optical diffusion effect.

[0064] For example, the color filter substrate 210, the liquid crystal layer 220 and the array substrate 230, the array substrate 230 includes a third glass substrate 231 and a first electrode layer 232 and a first polarizer 241 disposed on both sides of the third glass substrate 231, the color filter substrate 210 includes a fourth glass substrate 211 and a second electrode layer 212 and a second polarizer 242 disposed on both sides of the third glass substrate 231, the first electrode layer 232 and the second electrode layer 212 are located on a side close to the liquid crystal layer 220. A diffusion plate 170 is disposed between the third glass substrate 231 and the light source assembly 10, that is, a diffusion plate 170 is disposed on both the first light emitting side and the second light emitting side of the light source assembly 10. A third driving circuit 233 is also disposed on the third glass substrate 231, and the third driving circuit 233 is electrically connected to the first electrode layer 232 and the second electrode layer 212 to form an electric field that can deflect the liquid crystal of the liquid crystal layer 220.

[0065] Embodiment 2

[0066] The biggest difference between the double-sided display module in the second embodiment and the double-sided display module in the first embodiment is that the diffusion plate 170 and the third glass substrate 231 in the array substrate 230 are shared.

[0067] like Figure 4 As shown, the diffuser plate 170 is a glass substrate, and the diffuser plate 170 and the third glass substrate 231 are an integral structure. That is, in the design process of the array substrate 230 of the double-sided display panel 20, the glass diffuser plate 170 is used instead of the conventional glass substrate, so that the third glass substrate 231 has the functions of carrying and diffusing light at the same time.

[0068] By using the diffuser plate 170 and the third glass substrate 231 in the array substrate 230 to share a common glass substrate, the number of components is reduced, thereby reducing the thickness of the double-sided display module along the thickness direction of the display panel 20, which is conducive to making the double-sided display module lighter and thinner.

[0069] Embodiment 3

[0070] The biggest difference between the double-sided display module in the third embodiment and the double-sided display module in the first embodiment is that the light source assembly 10 includes two glass substrates that are parallel to each other and spaced apart, and the first light emitting element 120 and the second light emitting element 130 are arranged opposite to each other.

[0071] like Figure 5As shown, the substrate 110 includes a first glass substrate 111 and a second glass substrate 112. The first glass substrate 111 and the second glass substrate 112 are arranged parallel to each other and spaced apart along the thickness direction of the substrate 110. The side of the first glass substrate 111 close to the second glass substrate 112 is the first light emitting side, and the side of the second glass substrate 112 close to the first glass substrate 111 is the second light emitting side. That is, the first light emitting element 120 is arranged on the side of the first glass substrate 111 close to the first light emitting side, and the second light emitting element 130 is arranged on the side of the second glass substrate 112 close to the second light emitting side, so that the light emitting sides of the first light emitting element 120 and the second light emitting element 130 are arranged opposite to each other.

[0072] Through the above arrangement, the light emitted by the first light-emitting element 120 enters the display panel 20 located on the first light-emitting side only after passing through the second glass substrate 112, and the light emitted by the second light-emitting element 130 enters the display panel 20 located on the second light-emitting side only after passing through the first glass substrate 111, which is suitable for different display scenarios.

[0073] like Figure 5 As shown, in some embodiments, the number of the first light-emitting elements 120 is multiple, and the number of the second light-emitting elements 130 is multiple; along the thickness direction of the base 110, the projection of the second light-emitting element 130 on the second glass substrate 112 is located between the projections of two adjacent first light-emitting elements 120 on the second glass substrate 112.

[0074] The projection of the second light emitting element 130 on the second glass substrate 112 being located between the projections of two adjacent first light emitting elements 120 on the second glass substrate 112 means that the first light emitting element 120 and the second light emitting element 130 are staggered along the thickness direction of the base 110 .

[0075] Through the above arrangement, the light emitted from the first light emitting element 120 can be staggered with the light emitted from the second light emitting element 130, thereby reducing the mutual influence between the two and improving the display effect.

[0076] like Figure 5 As shown, in some embodiments, a first optical layer 161 is disposed between the first glass substrate 111 and the first light emitting element 120 , and the first optical layer 161 can allow light to pass through.

[0077] The first optical layer 161 plays a role in allowing light to pass through. The first optical layer 161 may be a high-definition light-transmitting film or a high-definition light-transmitting coating, etc., so that the light output effect of the light source assembly 10 is better. Of course, the first optical layer 161 may also be a semi-transparent and semi-reflective film or a semi-transparent and semi-reflective coating, so that when light enters the first optical layer 161, part of the light is transmitted and the other part is reflected.

[0078] Through the above arrangement, the light emitted from the first light emitting side of the light source assembly 10 is made more uniform.

[0079] like Figure 5 As shown, in some embodiments, a first optical layer 161 is provided on one side of the first glass substrate 111 where the first light-emitting element 120 is disposed, and the first optical layer 161 is capable of transmitting light, and a second optical layer 162 is provided on one side of the second glass substrate 112 where the second light-emitting element 130 is disposed, and the second optical layer 162 is capable of transmitting light.

[0080] Through the above-mentioned arrangement, a part of the light emitted by the first light-emitting element 120 is transmitted through the second optical layer 162 and the second glass substrate 112 in sequence to the first light-emitting side, and the other part is transmitted to the second light-emitting side after being reflected by the second optical layer 162. A part of the light emitted by the second light-emitting element 130 is transmitted through the first optical layer 161 and the first glass substrate 111 in sequence to the second light-emitting side, and the other part is transmitted to the first light-emitting side after being reflected by the first optical layer 161, which is beneficial to improving the uniformity of light on the two light-emitting sides of the light source assembly 10.

[0081] In addition, as needed, the second optical layer 162 can be provided only on one side of the substrate 110 where the second light-emitting element 130 is provided, without providing the first optical layer 161, so that the light output amounts on the first light output side and the second light output side of the light source assembly 10 are different to adapt to different scenarios.

[0082] like Figure 5 As shown, in some embodiments, the double-sided display module further includes two diffusion plates 170, the diffusion plates 170 are glass substrates, one of the diffusion plates 170 is an integral structure with the first glass substrate 111, and the other diffusion plate 170 is an integral structure with the second glass substrate 112. The first glass substrate 111 and the second glass substrate 112 can not only transmit light but also diffuse light. Such a configuration makes the light emitted from the first light-emitting side and the second light-emitting side of the light source assembly 10 more uniform, and no additional structural parts are added, which is conducive to the light and thin design of the double-sided display module.

[0083] Embodiment 4

[0084] The biggest difference between the double-sided display module in the fourth embodiment and the double-sided display module in the third embodiment is that the third glass substrate 231 of one of the two display panels 20 is an integral structure with the first glass substrate 111, and the third glass substrate 231 of the other display panel 20 is an integral structure with the second glass substrate 112.

[0085] like Figure 6As shown, the display panel 20 includes a color film substrate 210, a liquid crystal layer 220 and an array substrate 230. The array substrate 230 includes a third glass substrate 231. The third glass substrate 231 of one of the two display panels 20 is an integral structure with the first glass substrate 111, and the third glass substrate 231 of the other display panel 20 is an integral structure with the second glass substrate 112.

[0086] Through the above arrangement, the thickness of the double-sided display module omits the thickness of the two glass substrates, which is conducive to the lightness and integration of the double-sided display module. In addition, the assembly process is reduced, which is conducive to improving the assembly accuracy.

[0087] like Figure 6 As shown, in some embodiments, the double-sided display module further includes a diffuser 170, the diffuser 170 is a glass substrate, and the diffuser 170 is an integral structure with the third glass substrate 231. That is, the first light-emitting element 120 or the second light-emitting element 130 is provided on the side of the third glass substrate 231 away from the liquid crystal layer 220, so that the first light-emitting element 120 and the second light-emitting element 130 are opposite.

[0088] Through the above arrangement, the third glass substrate 231 of one of the two display panels 20, the first glass substrate 111 and a diffuser 170 share a glass substrate, and the third glass substrate 231 of the other display panel 20, the second glass substrate 112 and the other diffuser 170 share a glass substrate, which further reduces the number of components, thereby facilitating the thinning and integration of the double-sided display module. In addition, the assembly process is reduced, which is beneficial to improving the assembly accuracy.

[0089] like Figure 6 As shown, in some embodiments, a third driving circuit 233 is further provided on a side of the third glass substrate 231 close to the liquid crystal layer 220, a first driving circuit 141 is provided on a side of one of the two third glass substrates 231 away from the liquid crystal layer 220, and a second driving circuit 142 is provided on a side of the other third glass substrate 231 away from the liquid crystal layer 220, and the first driving circuit 141, the second driving circuit 142 and the third driving circuit 233 are all located at the edge of the third glass substrate 231.

[0090] Through the above arrangement, the space of the third glass substrate 231 is fully utilized, which is further beneficial to the miniaturized design of the double-sided display module.

[0091] Embodiment 5

[0092] The present application also provides a double-sided display, comprising the double-sided display module in any of the above embodiments.

[0093] The beneficial effect of the double-sided display provided by the present application is that: by arranging the first light-emitting element 120 and the second light-emitting element 130 on the substrate 110 that can allow light to pass through, the light output on the first light-emitting side of the light source assembly 10 includes not only the direct light emitted by the first light-emitting element 120 located on the first light-emitting side, but also the indirect light after the second light-emitting element 130 located on the second light-emitting side passes through the substrate 110, and the light output on the second light-emitting side includes not only the direct light emitted by the second light-emitting element 130 located on the second light-emitting side, but also the indirect light after the first light-emitting element 120 located on the first light-emitting side passes through the substrate 110, so that the light output of the light source assembly 10 to the two light-emitting sides is relatively large, which is beneficial to improving the display effect. The two display panels 20 are respectively arranged on the two light-emitting sides of the light source assembly 10, and the two display panels 20 share one light source assembly 10 to form a double-sided display module, so that not only the purpose of integrated double-sided display is achieved, but also the structure of the double-sided display module is optimized. In addition, such a design omits the supporting parts in the related art, which optimizes the structure of the double-sided display module and reduces the thickness on the one hand, and reduces the cost on the other hand.

[0094] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
