[0060] <Double-sided display device>

[0061] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 FIG. 1 is a three-dimensional schematic diagram of a double-sided display device 100 according to Example 1 in one embodiment of the present invention. Figure 2 Draw according to Figure 1 An exploded view of the double-sided display device 100 of Example 1 in the implementation manner, Figure 3 Draw according to Figure 1 Schematic diagram of the light guide module 130, the second frame 142 and the light source element 150 in Embodiment 1. Figure 1 , Figure 2 and Figure 3It can be seen that the double-sided display device 100 of the first embodiment includes a first display panel 110, a second display panel 120, a light guide module 130, a frame assembly 140, a light source element 150 and a side panel assembly 160. The light guide module 130 is disposed between the first display panel 110 and the second display panel 120, and the light guide module 130 includes a light guide plate 131, a first film layer group 132 and a second film layer group 133. The first film layer group 132 is disposed between the first display panel 110 and the light guide plate 131, and the second film layer group 133 is disposed between the second display panel 120 and the light guide plate 131. The frame assembly 140 includes a first frame 141 and a second frame 142. The first frame 141 and the second frame 142 are connected to form a positioning space (not shown in the figure). The light guide module 130 is surrounded by the first frame 141 and the second frame 142 and is positioned in the positioning space. The light source element 150 is disposed in one of the first frame 141 and the second frame 142, and the light source element 150 corresponds to the light guide plate 131. The side panel assembly 160 is fixed to the frame assembly 140, and includes a first side panel 161 and a second side panel 162. The first side panel 161 and the second side panel 162 are disposed correspondingly, and the first display panel 110, the light guide module 130 and the second display panel 120 are located between the first side panel 161 and the second side panel 162. In this way, the structural design of the double-sided display device 100 can be simplified and the number of assembly materials can be reduced, so as to simplify the assembly operation and improve the production yield of the double-sided display device 100.

[0062] Furthermore, the second frame 142 of the double-sided display device 100 may include a pressure strip element 143 and a pressing member 144, the pressing member 144 may correspond to one side of the light guide module 130, and the pressure strip element 143 may correspond to the other side of the light guide module 130. Thus, the positioning stability of the light guide module 130 in the double-sided display device 100 can be improved.

[0063] Specifically, the frame assembly 140 can enhance the structural strength of the double-sided display device 100, wherein each component of the frame assembly 140 (i.e., the first frame 141, the pressure strip element 143 of the second frame 142, and the pressing component 144) can be an aluminum extrusion component, which has high strength and lightweight characteristics and is corrosion-resistant. Furthermore, anodizing the surface of the frame assembly 140 using an electrochemical method can prevent aluminum oxidation and increase the mechanical properties of the surface of the frame assembly 140. Furthermore, the seamless bending process can form the first frame 141 or the second frame 142 into an integrally formed part according to demand, thereby avoiding the light transmittance problem of the double-sided display device 100 caused by the joint gap between the parts, thereby increasing the structural airtightness and reliability of the double-sided display device 100.

[0064] Please refer to Figure 4 and Figure 5 , Figure 4 Draw according to Figure 1 A schematic diagram of the pressing member 144 and the first frame 141 in Embodiment 1, Figure 5 Draw according to Figure 1 Schematic diagram of the first display panel 110, the first side panel 161 and the circuit board 163 in Embodiment 1. Figure 4 It can be seen that the two ends of the pressing part 144 of the second frame 142 may include two extensions 145, and the extensions 145 may be perpendicular to an axial direction of the pressure strip element 143. Furthermore, the extensions 145 may be fixed to the first frame 141. Thereby, the structural stability of the frame assembly 140 can be strengthened. Specifically, the pressing part 144 can be used as a heat sink, wherein the extensions 145 can conduct heat energy generated by the light source element 150 to solve the heat dissipation problem of the light source element 150. In addition, the extensions 145 fixed to the first frame 141 can increase the structural strength of the double-sided display device 100. By Figure 5 It can be seen that the bottom of the first display panel 110 corresponds to the first side panel 161. Specifically, a circuit board 163 may be disposed in the first side panel 161, and the circuit board 163 may be electrically connected to the first display panel 110 and the second display panel 120, thereby integrating the display functions of the first display panel 110 and the second display panel 120, and increasing the functional variability of the double-sided display device 100.

[0065] Please refer to Figure 6 and Figure 7 , Figure 6 Draw according to Figure 1 A schematic diagram of the elastic portion 146 in Example 1, Figure 7 Draw according to Figure 1 Schematic diagram of the elastic body 147 in Example 1. Figure 6 It can be seen that the first frame 141 may include two elastic parts 146, and the two elastic parts 146 may respectively physically contact the two sides of the light guide module 130. Specifically, the elastic part 146 may be made of foam. In this way, the friction between the light guide module 130 and the first frame 141 can be prevented, and the damage to the first film layer group 132 and the second film layer group 133 of the light guide module 130 during the assembly process can be reduced, which helps to improve the production yield of the double-sided display device 100. Figure 7 It can be seen that the second frame 142 may include two elastic bodies 147, and the two elastic bodies 147 may respectively physically contact the two sides of the light guide plate 131. Specifically, the material of the elastic body 147 may be a silicone strip. The elastic body 147 is used to press against the light guide plate 131 to prevent the misalignment problem between the light guide plate 131 and the light source element 150, thereby avoiding the light leakage problem.

[0066] Please refer to Figure 8 and Fig. 9, Figure 8 Draw according to Figure 1 A schematic diagram of the positioning column 148 and the positioning groove 134 in Example 1, Fig. 9 Draw according to Figure 1 A partial enlarged view of the light guide plate 131 in Example 1. Figure 8 It can be seen that the first frame 141 may include a positioning post 148, the light guide module 130 may include a positioning groove 134, and the positioning post 148 may correspond to the positioning groove 134. In this way, the light guide module 130 can be arranged in the first frame 141 to guide and improve the positioning reliability. Fig. 9 It can be known that the light guide plate 131 may include two substrates 135 and an ink layer 136, and the ink layer 136 may be disposed between the two substrates 135. In detail, the light guide plate 131 is made by a printing composite process, which can be applied to various types of materials and can reduce the thickness of the light guide plate 131. In the prior art, the components of the double-sided display screen need to include two groups of traditional light guide modules, each group of traditional light guide modules includes at least one traditional light guide plate, one light source, one reflective sheet and one heat sink to achieve the double-sided light guide function. Because the components are numerous and complex, the material and labor costs are high. Specifically, the light guide plate 131 of the double-sided display device 100 of Example 1 adopts a printing composite process, using a light guide plate 131 and a light source element 150, and can also cooperate with a heat sink element (not shown) to achieve the effect of double-sided light guide and provide high brightness, while saving manufacturing costs.

Specifically, the positioning structure 149 matches the alignment hole 164 in shape, and the positioning structure 149 is correspondingly inserted into the alignment hole 164 to achieve the limiting function. Furthermore, screws can be used to fix the first display panel 110, the light guide module 130 and the second display panel 120 to the side panel assembly 160 to ensure structural strength.
