Description

Technical Field

[0001] The present application relates to the field of display panels, and in particular to a light splitting module and a display device. Background Art

[0002] Generally, a display device can perform front-facing display. However, with the advancement of technology and the diversification of application scenarios, a display device that can only perform front-facing display cannot meet the diverse needs of application scenarios. Utility Model Content

[0003] In a first aspect, an embodiment of the present application provides a splitter module, the splitter module comprising:

[0004] a light source for emitting light;

[0005] A light guide plate, the light guide plate comprising a light incident surface, a first light exiting surface, and a second light exiting surface, the light incident surface being disposed adjacent to the light source, the first light exiting surface being connected to the light incident surface in a curved manner, the second light exiting surface being connected to the light incident surface in a curved manner, and the second light exiting surface being disposed opposite to the first light exiting surface, and the light source incident on the light guide plate from the light incident surface being emitted through the first light exiting surface and the second light exiting surface;

[0006] a first dimming plate, disposed on one side of the first light emitting surface, the first dimming plate having a plurality of first dimming units, each of the first dimming units having a light-transmitting state and a light-opaque shielding state; and

[0007] The second dimming plate is arranged on one side of the second light-emitting surface. The second dimming plate has multiple second dimming units. Each second dimming unit has a light-transmitting state and a shielding state, so that the splitting module has a first single-sided light-emitting mode, a second single-sided light-emitting mode and a double-sided light-emitting mode.

[0008] In a second aspect, an embodiment of the present application provides a display device, comprising:

[0009] The optical splitting module as described in the first aspect;

[0010] a first display panel, the first display panel being disposed on a side of the first dimming plate facing away from the second dimming plate; and

[0011] The second display panel is arranged on a side of the second dimming plate away from the first dimming plate.

[0012] In summary, in the optical splitter module provided in the embodiment of the present application, the light emitted by the light source enters the light guide plate from the light incident surface, and exits through the first light exit surface and the second light exit surface of the light guide plate. The light exiting from the first light exit surface irradiates the first dimming plate. When the first dimming unit of the first dimming plate is in a light-transmitting state, the light irradiated to the first dimming plate can exit through the first dimming plate; when the first dimming unit of the first dimming plate is in a shielding state, the light irradiated to the first dimming plate cannot exit through the first dimming plate. Correspondingly, the light exiting from the second light exit surface irradiates the second dimming plate. When the second dimming unit of the second dimming plate is in a light-transmitting state, the light irradiated to the second dimming plate can exit through the second dimming plate; when the second dimming unit of the second dimming plate is in a shielding state, the light irradiated to the second dimming plate cannot exit through the second dimming plate. Thus, by controlling the first dimming unit of the first dimming plate and the second dimming unit of the second dimming plate, the optical splitter module can have a first single-sided light-emitting mode in which light is emitted only from the first dimming plate and not from the second dimming plate; a second single-sided light-emitting mode in which light is emitted only from the second dimming plate and not from the first dimming plate; and a double-sided light-emitting mode in which light is emitted from both the first dimming plate and the second dimming plate. When the optical splitter module is applied to a display device, the display device can have multiple display modes, thereby being able to meet display requirements in different scenarios and having a relatively wide range of application scenarios.

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] Please also refer to Figure 1 and Figure 2 , Figure 1 A three-dimensional schematic diagram of a display device provided in one embodiment of the present application; Figure 2 for Figure 1The display device shown is a cross-sectional schematic diagram along line II. The display device 1 includes a spectrometer module 10, a first display panel 30 and a second display panel 50. The first display panel 30 and the second display panel 50 are respectively arranged on opposite sides of the spectrometer module 10. The display device 1 has a first single-sided display mode in which the first display panel 30 displays and the second display panel 50 does not display, a second single-sided display mode in which the first display panel 30 does not display and the second display panel 50 displays, and a double-sided display mode in which both the first display panel 30 and the second display panel 50 display. Specifically, the spectrometer module 10 has a first surface 10a and a second surface 10b that can emit light, wherein the first surface 10a and the second surface 10b are arranged opposite to each other. The first display panel 30 is arranged on the side where the first surface 10a is located, and the second display panel 50 is arranged on the side where the second surface 10b is located.

[0036] See also Figure 3 、 Figure 4 and Figure 5 , Figure 3 for Figure 2 Schematic diagram of the light splitting module shown in the figure when it is in the first single-side light emitting mode; Figure 4 for Figure 2 Schematic diagram of the light splitting module shown in the second single-side light emitting mode; Figure 5 for Figure 2 Schematic diagram of the spectrometer module shown in the figure when it is in the double-sided light emitting mode. The spectrometer module 10 has a first single-sided light emitting mode that emits light only from the first surface 10a, and does not emit light from the second surface 10b. The spectrometer module 10 also has a second single-sided light emitting mode that emits light only from the second surface 10b, and does not emit light from the first surface 10a. The spectrometer module 10 also has a double-sided light emitting mode that emits light from the first surface 10a and from the second surface 10b. When the spectrometer module 10 emits light from the first surface 10a, the spectrometer module 10 can serve as a backlight module for the first display panel 30; when the spectrometer module 10 emits light from the second surface 10b, the spectrometer module 10 can serve as a backlight module for the second display panel 50.

[0037] Therefore, in one embodiment, when the optical splitter module 10 is in the first single-sided light emitting mode, the display device 1 is in a first single-sided display mode in which the first display panel 30 is in operation and the second display panel 50 is inoperative. When the optical splitter module 10 is in the second single-sided light emitting mode, the display device 1 is in a second single-sided display mode in which the first display panel 30 is in operation and the second display panel 50 is in operation. When the optical splitter module 10 is in the double-sided light emitting mode, the display device 1 is in a double-sided display mode in which the first display panel 30 is in operation and the second display panel 50 is in operation.

[0038] The first display panel 30 is a liquid crystal display panel, and the second display panel 50 is a liquid crystal display panel. The first display panel 30 includes a first array substrate 310 and a first color filter substrate 320 disposed in opposite directions. The second display panel 50 includes a second array substrate 510 and a second color filter substrate 520 disposed in opposite directions.

[0039] In summary, the display device 1 provided in the embodiment of the present application has a first single-sided display mode, a second single-sided display mode and a double-sided display mode. Therefore, it can meet the display requirements in different scenarios and has a relatively wide range of application scenarios.

[0040] The above description is only a description of an embodiment of the display device 1 to which the optical splitter module 10 is applied, and it should be understood that it should not be construed as limiting the optical splitter module 10 provided in the embodiment of the present application.

[0041] See also Figure 6 , Figure 6 for Figure 2A schematic view of a light splitting module is shown. The light splitting module 10 includes a light source 110, a light guide plate 120, a first light adjusting plate 130 and a second light adjusting plate 140. The light source 110 is configured to emit light. The light guide plate 120 includes an incident surface 120a, a first emergent surface 120b and a second emergent surface 120c. The incident surface 120a is disposed adjacent to the light source 110. The first emergent surface 120b is connected to the incident surface 120a by bending. The second emergent surface 120c is connected to the incident surface 120a by bending. The second emergent surface 120c is disposed opposite to the first emergent surface 120b. The light emitted from the light source 110 and incident on the light guide plate 120 is emitted from the first emergent surface 120b and the second emergent surface 120c. The first light adjusting plate 130 is disposed on one side of the first emergent surface 120b. The first light adjusting plate 130 includes a plurality of first light adjusting units 130a. Each of the first light adjusting units 130a has a light transmitting state and a light shielding state. The second light adjusting plate 140 is disposed on one side of the second emergent surface 120c. The second light adjusting plate 140 includes a plurality of second light adjusting units 140a. Each of the second light adjusting units 140a has a light transmitting state and a light shielding state. The light splitting module 10 has a first single surface light emitting mode, a second single surface light emitting mode and a double surface light emitting mode.

[0042] The light source 110 can be, but is not limited to, a light emitting diode or a light emitting lamp strip. The number of the light source 110 is not limited.

[0043] The light guide plate 120 is also referred to as a middle substrate. The light guide plate 120 is a high-transmittance substrate with high light transmittance. The light guide plate 120 can be a glass substrate or a plastic substrate. The light guide plate 120 is configured to convert the light incident on the incident surface 120a into surface light and emit the surface light from the first emergent surface 120b and the second emergent surface 120c.

[0044] The incident surface 120a is a surface of the light guide plate 120 adjacent to the light source 110. The incident surface 120a is configured to receive the light emitted from the light source 110. In the present embodiment, the light guide plate 120 has two incident surfaces 120a disposed opposite to each other. Correspondingly, the light splitting module 10 includes two light sources 110. One of the two light sources 110 is disposed corresponding to one of the two incident surfaces 120a. The other of the two light sources 110 is disposed corresponding to the other of the two incident surfaces 120a. It can be understood that in other embodiments, the light guide plate 120 can have one incident surface 120a or three incident surfaces 120a or more incident surfaces.

[0045] In the illustration of this embodiment, the first light emitting surface 120b is located on the upper surface of the light guide plate 120, and the second light emitting surface 120c is located on the lower surface of the light guide plate 120. It is understandable that the positions of the first light emitting surface 120b and the second light emitting surface 120c vary with the placement of the light guide plate 120.

[0046] The light source 110 incident on the light guide plate 120 from the light incident surface 120 a is converted into surface light by the light guide plate 120 and emitted from the first surface 131 a and the second surface 131 b .

[0047] The plurality of first dimming cells 130a of the first dimming plate 130 can be arranged in an array. When the first dimming cells 130a are in a light-transmitting state, light emitted from the first surface 131a to the first dimming cells 130a can be emitted through the first dimming cells 130a. When the first dimming cells 130a are in a shielded state, light emitted from the first surface 131a to the first dimming cells 130a cannot be emitted through the first dimming cells 130a.

[0048] Accordingly, the plurality of second dimming cells 140a of the second dimming plate 140 can be arranged in an array. When the second dimming cells 140a are in a light-transmitting state, light emitted from the second surface 131b to the second dimming cells 140a can be emitted through the second dimming cells 140a. When the second dimming cells 140a are in a shielded state, light emitted from the second surface 131b to the second dimming cells 140a cannot be emitted through the second dimming cells 140a.

[0049] In one embodiment, the surface of the first dimming plate 130 facing away from the light guide plate 120 can serve as the first surface 10a of the light splitting module 10 ; the surface of the second dimming plate 140 facing away from the light guide plate 120 can serve as the second surface 10b of the light splitting module 10 .

[0050] Please also refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 6, when the optical splitter module 10 is in the first single-sided light emitting mode, the first dimming unit 130a is in the light transmitting state, and the second dimming unit 140a is in the shielding state. When the optical splitter module 10 is applied to the display device 1, the display device 1 is in the first single-sided display mode. When the optical splitter module 10 is in the second single-sided light emitting mode, the first dimming unit 130a is in the shielding state, and the second dimming unit 140a is in the light transmitting state. When the optical splitter module 10 is applied to the display device 1, the display device 1 is in the second single-sided display mode. When the optical splitter module 10 is in the double-sided light emitting mode, the first dimming unit 130a is in the light transmitting state, and the second dimming unit 140a is also in the light transmitting state. When the optical splitter module 10 is applied to the display device 1, the display device 1 is in the double-sided display mode. It should be noted that, when the display device 1 is in the double-sided display mode, the content displayed on the first display panel 30 and the content displayed on the second display panel 50 may be the same or different.

[0051] In summary, in the optical splitter module 10 provided in the embodiments of the present application, light emitted by the light source 110 enters the light guide plate 120 through the light incident surface 120a and exits through the first light exit surface 120b and the second light exit surface 120c of the light guide plate 120. Light exiting from the first light exit surface 120b irradiates the first dimming plate 130. When the first dimming unit 130a of the first dimming plate 130 is in a light-transmitting state, the light irradiated by the first dimming plate 130 can exit through the first dimming plate 130. When the first dimming unit 130a of the first dimming plate 130 is in a shielded state, the light irradiated by the first dimming plate 130 cannot exit through the first dimming plate 130. Correspondingly, the light emitted from the second light-emitting surface 120c is irradiated to the second dimming plate 140. When the second dimming unit 140a of the second dimming plate 140 is in a light-transmitting state, the light irradiated to the second dimming plate 140 can be emitted through the second dimming plate 140; when the second dimming unit 140a of the second dimming plate 140 is in a shielding state, the light irradiated to the second dimming plate 140 cannot be emitted through the second dimming plate 140. Thus, by controlling the first dimming unit 130a of the first dimming plate 130 and the second dimming unit 140a of the second dimming plate 140, the optical splitter module 10 can have a first single-sided light emission mode in which light is emitted only from the first dimming plate 130 and no light is emitted from the second dimming plate 140; a second single-sided light emission mode in which light is emitted only from the second dimming plate 140 and no light is emitted from the first dimming plate 130; and a dual-sided light emission mode in which light is emitted from both the first dimming plate 130 and the second dimming plate 140. When the optical splitter module 10 is applied to the display device 1, the display device 1 can have multiple display modes, thereby being able to meet display requirements in different scenarios and having a relatively wide range of application scenarios.

[0052] See also Figure 7 , Figure 7 for Figure 6Detailed identification diagram of the optical splitter module shown in . The first dimming plate 130 includes a first substrate 131, a first driving layer 132, a first spacer layer 133 and a first electrowetting fluid 134. The first substrate 131 has a first surface 131a and a second surface 131b that are arranged opposite to each other. The first substrate 131 is arranged at intervals on one side of the first light-emitting surface 120b, and the second surface 131b is away from the light guide plate 120 compared to the first surface 131a. The first driving layer 132 is arranged on the first surface 131a and includes a plurality of first driving parts 1321, and one first driving part 1321 corresponds to one first dimming unit 130a. The first spacer layer 133 includes a plurality of first spacers 1331. The plurality of first spacers 1331 are arranged at intervals between the first driving layer 132 and the first light-emitting surface 120b of the light guide plate 120 to form a plurality of first cavities 133a that are arranged at intervals. The first electrowetting fluid 134 is disposed within the first cavity 133a and occupies a portion of the space. The first dimming cell 130a includes two first partitions 1331 defining the first cavity 133a and the first electrowetting fluid 134 located within the first cavity 133a. When the first driving unit 1321 corresponding to the first dimming cell 130a is not loaded with the first control voltage, the first electrowetting fluid 134 in the first dimming cell 130a adheres to one of the two first partitions 1331 in the first dimming cell 130a, with a gap between the first and second partitions 1331, thereby maintaining the first dimming cell 130a in the light-transmitting state.

[0053] The first substrate 131 is also referred to as an upper substrate, and the first substrate 131 may be a glass, acrylic, or other substrate. In the schematic diagram of this embodiment, the first surface 131a is a lower surface, and the second surface 131b is an upper surface.

[0054] A first driving unit 1321 is set corresponding to a first dimming unit 130a, and different first driving units 1321 correspond to different first dimming units 130a. Therefore, different first dimming units 130a can be controlled separately. In other words, when the light emitted by the splitter module 10 is irradiated to the first dimming plate 130, the light emitted from the first dimming plate 130 can be controlled in a zoned manner, thereby improving the contrast of the display image of the first display panel 30 of the display device 1 to which the splitter module 10 is applied.

[0055] The first electrowetting fluid 134 includes a first liquid body and first reflective particles, and the first reflective particles are distributed in the first liquid body. The first liquid body is an electrowetting fluid 640 body, which can be an organic polymer solution such as silicone oil. The first reflective particles can be metal particles with high reflectivity, such as gold, silver, copper, or aluminum particles. When light is irradiated onto the first reflective particles, the first reflective particles can reflect the irradiated light. The particle size range of the first reflective particles can be less than or equal to 100 microns, so that a better reflective effect can be achieved. Since the first electrowetting fluid 134 includes the first reflective particles, when light is irradiated onto the first electrowetting fluid 134, the light cannot pass through the first electrowetting fluid 134.

[0056] The first electrowetting fluid 134 is disposed in the first cavity 133 a and occupies a portion of the space of the first cavity 133 a , but does not completely fill the space of the first cavity 133 a .

[0057] When the first driving unit 1321 corresponding to the first dimming unit 130a is not loaded with the first control voltage, the first electrowetting fluid 134 is adhered to form one of the two first spacers 1331 in the first dimming unit 130a, and has a gap with the other of the two first spacers 1331. When light is irradiated to the first dimming unit 130a, the light can be emitted from the gap between the first electrowetting fluid 134 and the other of the two first spacers 1331. Therefore, the first dimming unit 130a is in a light-transmitting state.

[0058] In summary, the first dimming plate 130 provided in the embodiment of the present application, when a first driving portion 1321 corresponding to the first dimming unit 130a is not loaded with the first control voltage, the light irradiated to the first dimming unit 130a can be emitted through the gap between the first electrowetting fluid 134 and the other of the two first spacers 1331, and therefore, the first dimming unit 130a is in a light-transmitting state. In addition, one first driving portion 1321 is set corresponding to one first dimming unit 130a, and different first driving portions 1321 are set corresponding to different first dimming units 130a. Therefore, different first dimming units 130a can be controlled separately. In other words, when the light emitted by the splitter module 10 is irradiated to the first dimming plate 130, the light emitted from the first dimming plate 130 can be controlled in a partitioned manner, thereby improving the contrast of the display image of the first display panel 30 of the display device 1 to which the splitter module 10 is applied.

[0059] Furthermore, when the first driving part 1321 corresponding to the first dimming unit 130a is loaded with a first control voltage, the first electrowetting fluid 134 in the first dimming unit 130a adheres to the two first spacers 1331 and the first driving part 1321 in the first dimming unit 130a, so that the first dimming unit 130a has the shielding state.

[0060] When the first driving part 1321 corresponding to the first dimming unit 130a is loaded with the first control voltage, the first electrowetting fluid 134 in the first control unit adheres to the two first spacers 1331 and the first driving part 1321 in the first dimming unit 130a. Therefore, there is no gap between the two first spacers 1331 of the first dimming unit 130a, and the light irradiated to the first dimming unit 130a cannot pass through the first electrowetting fluid 134, so that the first dimming unit 130a is in the shielding state.

[0061] In one embodiment, when the first driving unit 1321 is loaded with a first regulating voltage, the first regulating voltage may be, but is not limited to, 5V to 30V. This allows the first regulating voltage to have a better regulating effect on the first electrowetting fluid 134 .

[0062] It can be seen that by loading the first control voltage on the first driving part 1321, the first dimming unit 130a corresponding to the first driving part 1321 can be in a shielded state; by not loading the first control voltage on the first driving part 1321, the first dimming unit 130a corresponding to the first driving part 1321 can be in a light-transmitting state, thereby enabling precise control of the first dimming unit 130a. In other words, when the light emitted by the splitter module 10 is irradiated on the first dimming plate 130, the partitioned control of the light emitted from the first dimming plate 130 can be achieved, thereby improving the contrast of the display image of the first display panel 30 of the display device 1 to which the splitter module 10 is applied.

[0063] Further, see Figure 8 , Figure 8A schematic diagram of a spectrometer module is provided for another embodiment of the present application. In the schematic diagram of this embodiment, the packaging frame is not illustrated. It can be understood that in this embodiment, the spectrometer module may include a packaging frame or may not include the packaging frame. The first dimming plate 130 also includes a first film layer 135. The first film layer 135 is arranged on the side of the first driving layer 132 away from the first substrate 131, and the first film layer 135 includes a plurality of first parts 1351, and the first part 1351 is arranged corresponding to the first driving part 1321. When the first driving part 1321 is not loaded with the first regulating voltage, the first part 1351 is a hydrophobic part; when the first driving part 1321 is loaded with the first regulating voltage, the first part 1351 is a hydrophilic part.

[0064] When the first driving part 1321 is not loaded with the first regulating voltage, the first part 1351 is a hydrophobic part, that is, the first part 1351 exhibits a hydrophobic property. Therefore, when the first driving part 1321 is not loaded with the first regulating voltage, the first electrowetting fluid 134 is adhered to form one of the two first spacers 1331 in the first dimming unit 130a, and has a gap with the other of the two first spacers 1331, so that the first dimming unit 130a is in a light-transmitting state.

[0065] When the first driving portion 1321 is loaded with the first regulating voltage, the surface characteristics of the first portion 1351 are changed, so that the first portion 1351 exhibits a hydrophilic property. Therefore, the first portion 1351 is a hydrophilic portion.

[0066] Therefore, when the first driving unit 1321 is loaded with the first control voltage, the first electrowetting fluid 134 adheres to the two first spacers 1331 and the first driving unit 1321 in the first dimming unit 130a, so that the first dimming unit 130a is in the shielding state.

[0067] It can be seen that the first dimming unit 130a provided in the embodiment of the present application includes a first film layer 135, and the first film layer 135 includes multiple first parts 1351. The first driving part 1321 is not loaded with the first control voltage or loaded with the first control voltage so that the first part 1351 is hydrophobic or hydrophilic. When the first part 1351 is a hydrophobic part or a hydrophilic part, the effect on the first electrowetting fluid 134 is different, so that the first dimming unit 130a has a light-transmitting state or a shielding state.

[0068] Furthermore, the first dimming plate 130 further includes a first optical film 136. The first optical film 136 is disposed (e.g., by bonding) on ​​one side of the second surface 131b of the first substrate 131. The first optical film 136 may be an antireflection film or a brightness-averaging film. The inclusion of the first optical film 136 in the first dimming plate 130 improves the quality of light emitted from the first dimming plate 130.

[0069] The light guide plate 120 is described below. Figure 9 , Figure 9 A schematic diagram of a light guide plate, a first spacer layer, and a second spacer layer in a light splitting module provided in one embodiment. The light guide plate 120 includes a light guide body 121 and a plurality of first lattice dots 122. The light guide body 121 has a light incident surface 120a, a first light exiting surface 120b, and a second light exiting surface 120c. The plurality of first lattice dots 122 are disposed on the first light exiting surface 120b. Light transmitted within the light guide body 121 exits through the first lattice dots 122. The density of the first lattice dots 122 adjacent to the light incident surface 120a is less than the density of the first lattice dots 122 facing away from the light incident surface 120a.

[0070] Light incident from the light incident surface 120 a is generally totally reflected within the light guide body 121 . When the light strikes the first mesh dots 122 , the total reflection condition is destroyed, allowing the light to be emitted through the first mesh dots 122 .

[0071] The light intensity in the portion of the light guide body 121 adjacent to the light incident surface 120a is greater, while the light intensity in the portion away from the light incident surface 120a is less. Therefore, the density of the first lattice dots 122 adjacent to the light incident surface 120a is less than the density of the first lattice dots 122 away from the light incident surface 120a, thereby making the light emitted from the first light emitting surface 120b of the light guide plate 120 more uniform. It is understandable that when the light guide body 121 has a single light incident surface 120a, the density of the first lattice dots 122 adjacent to the light incident surface 120a is less than the density of the first lattice dots 122 away from the light incident surface 120a.

[0072] When the light guide body 121 has two light incident surfaces 120a arranged in opposite directions, with the center line L0 of the body of the light guide plate 120 as the boundary, the density of the first dots 122 adjacent to one of the two light incident surfaces 120a is less than the density of the area where the center line L0 of the light guide plate 120 is located; the density of the first dots 122 adjacent to the other of the two light incident surfaces 120a is less than the density of the area where the center line L0 of the light guide plate 120 is located.

[0073] Correspondingly, the light guide plate 120 further includes a plurality of second lattice dots 123. The plurality of second lattice dots 123 are disposed on the second light-emitting surface 120c. Light transmitted within the light guide body 121 is emitted through the second lattice dots 123. The density of the second lattice dots 123 adjacent to the light-incident surface 120a is lower than the density of the second lattice dots 123 away from the light-incident surface 120a.

[0074] Light incident from the light incident surface 120 a is generally totally reflected within the light guide body 121 . When the light strikes the second mesh dots 123 , the total reflection condition is destroyed, allowing the light to be emitted through the second mesh dots 123 .

[0075] The light intensity in the portion of the light guide body 121 adjacent to the light incident surface 120a is greater, while the light intensity in the portion away from the light incident surface 120a is less. Therefore, the density of the second lattice dots 123 adjacent to the light incident surface 120a is less than the density of the second lattice dots 123 away from the light incident surface 120a, thereby making the light emitted from the first light emitting surface 120b of the light guide plate 120 more uniform. It is understandable that when the light guide body 121 has a single light incident surface 120a, the density of the second lattice dots 123 adjacent to the light incident surface 120a is less than the density of the second lattice dots 123 away from the light incident surface 120a.

[0076] When the light guide body 121 has two light incident surfaces 120a arranged in opposite directions, with the center line L0 of the body of the light guide plate 120 as the boundary, the density of the second dots 123 adjacent to one of the two light incident surfaces 120a is less than the density of the area where the center line L0 of the light guide plate 120 is located; the density of the second dots 123 adjacent to the other of the two light incident surfaces 120a is less than the density of the area where the center line L0 of the light guide plate 120 is located.

[0077] Furthermore, the first mesh dots 122 avoid the area of ​​the first spacer 1331 .

[0078] Furthermore, the first dots 122 avoid the area of ​​the first spacer 1331. That is, the first dots 122 avoid the area of ​​the light guide body 121 corresponding to the first spacer 1331. In other words, the first dots 122 are not provided in the area of ​​the light guide plate 120 corresponding to the first spacer 1331. This increases the area of ​​the light reflection region within the light guide body 121, improving the light transmission characteristics within the light guide body 121. This allows more light to be emitted through the first dots 122, resulting in higher brightness of the light emitted from the light splitting module 10 via the first dimming plate 130.

[0079] Accordingly, the second mesh dots 123 avoid the area of ​​the second spacer 1431. That is, the second mesh dots 123 avoid the area of ​​the light guide body 121 corresponding to the second spacer 1431. In other words, the area of ​​the light guide plate 120 corresponding to the second spacer 1431 is not provided with the second mesh dots 123. This increases the area of ​​the light reflection region within the light guide body 121, improving the light transmission characteristics within the light guide body 121. This allows more light to be emitted through the second mesh dots 123, resulting in higher brightness of the light emitted from the light splitting module 10 via the second dimming plate 140.

[0080] Further, see Figure 7 In one embodiment, the first dimming unit 130a and the second dimming unit 140a are at least partially opposite to each other.

[0081] The first dimming unit 130a is at least partially opposite to the second dimming unit 140a. Thus, when the first dimming unit 130a of the first dimming plate 130 is in a shielded state (also referred to as the first dimming plate 130 is in a dark field), and the second dimming unit 140a of the second dimming plate 140 is in a light-transmitting state (also referred to as the second dimming plate 140 is in a bright field), the first dimming unit 130a can reflect light into the second dimming unit 140a that is at least partially opposite to the first dimming unit 130a, thereby increasing the brightness of the light emitted from the second dimming unit 140a.

[0082] In addition, the number and intensity of the multiple sub-light sources in the turned-on light source 110 can be adjusted according to the display status of the display device 1 used by the splitter module 10 and the display requirements of the first display panel 30 and the second display panel 50, thereby achieving the technical effect of reducing energy consumption.

[0083] Correspondingly, the first dimming unit 130a is at least partially opposite to the second dimming unit 140a. In this way, when the second dimming unit 140a of the second dimming plate 140 is in a shielded state (also called the second dimming plate 140 is in a dark field), and the first dimming unit 130a of the first dimming plate 130 is in a light-transmitting state (also called the first dimming plate 130 is in a bright field), the second dimming unit 140a can reflect light into the first dimming unit 130a that is at least partially opposite to the second dimming unit 140a, thereby increasing the brightness of the light emitted from the first dimming unit 130a.

[0084] Next, please refer to Figure 6 and Figure 7, the second dimming plate 140 is introduced in detail. The second dimming plate 140 includes a second substrate 141, a second driving layer 142 and a second electrowetting liquid 144. The second substrate 141 has a third surface 141a and a fourth surface 141b arranged opposite to each other. The second substrate 141 is arranged at intervals on one side of the second light-emitting surface 120c, and the fourth surface 141b is farther away from the light guide plate 120 than the third surface 141a. The second driving layer 142 is arranged on the third surface 141a and includes a plurality of second driving parts 1421, and one first driving part 1321 corresponds to one second dimming unit 140a. The second spacing layer 143 includes a plurality of second spacing parts 1431, and the plurality of second spacing parts 1431 are arranged at intervals between the second driving layer 142 and the second light-emitting surface 120c of the light guide plate to form a plurality of second cavities 143a arranged at intervals. The second electrowetting fluid 144 is disposed within the second cavity 143a and occupies a portion of the space. The second dimming cell 140a includes two second partitions 1431 defining the second cavity 143a and the second electrowetting fluid 144 located within the second cavity 143a. When the second driving unit 1421 corresponding to the second dimming cell 140a is not loaded with the second control voltage, the second electrowetting fluid 144 in the second dimming cell 140a is disposed adjacent to one of the two second partitions 1431 in the first dimming cell 130a, with a gap between the second electrowetting fluid 144 and the other of the two first partitions 1331, thereby maintaining the second dimming cell 140a in the light-transmitting state.

[0085] The second substrate 141 is also referred to as a lower substrate, and the second substrate 141 may be a glass, acrylic, etc. In the schematic diagram of this embodiment, the third surface 141a is an upper surface, and the fourth surface 141b is a lower surface.

[0086] A second driving unit 1421 is set corresponding to a second dimming unit 140a, and different second driving units 1421 correspond to different second dimming units 140a. Therefore, different second dimming units 140a can be controlled separately. In other words, when the light emitted by the splitter module 10 is irradiated to the second dimming plate 140, the light emitted from the second dimming plate 140 can be controlled in a zoned manner, thereby improving the contrast of the display image of the second display panel 50 of the display device 1 to which the splitter module 10 is applied.

[0087] The second electrowetting fluid 144 includes a second liquid body and second reflective particles, and the second reflective particles are distributed in the second liquid body. The second liquid body is an electrowetting fluid 640 body, which can be an organic polymer solution such as silicone oil. The second reflective particles can be metal particles with high reflectivity, such as gold, silver, copper, or aluminum particles. When light is irradiated onto the second reflective particles, the second reflective particles can reflect the irradiated light. The particle size range of the second reflective particles can be less than or equal to 100 microns, so that a better reflective effect can be achieved. Since the second electrowetting fluid 144 includes the second reflective particles, when light is irradiated onto the second electrowetting fluid 144, the light cannot pass through the second electrowetting fluid 144.

[0088] The second electrowetting liquid 144 is disposed in the second cavity 143 a and occupies a portion of the space of the second cavity 143 a but does not completely fill the space of the second cavity 143 a .

[0089] When the second driving unit 1421 corresponding to the second dimming unit 140a is not loaded with the second control voltage, the second electrowetting liquid 144 is adhered to form one of the two second spacers 1431 in the second dimming unit 140a, and has a gap with the other of the two second spacers 1431. When light is irradiated to the second dimming unit 140a, the light can be emitted from the gap between the second electrowetting liquid 144 and the other of the two second spacers 1431. Therefore, the second dimming unit 140a is in a light-transmitting state.

[0090] In summary, the second dimming substrate provided in the embodiment of the present application is such that when a second driving portion 1421 corresponding to the second dimming cell 140a is not loaded with the second control voltage, the light irradiated to the second dimming cell 140a can be emitted through the gap between the second electrowetting liquid 144 and the other of the two second spacers 1431, and thus the second dimming cell 140a is in a light-transmitting state. In addition, one second driving portion 1421 is provided corresponding to one second dimming cell 140a, and different second driving portions 1421 are provided corresponding to different second dimming cells 140a. Therefore, separate control of different second dimming cells 140a can be achieved. In other words, when the light emitted by the optical splitter module 10 is irradiated to the second dimming plate 140, partitioned control of the light emitted from the second dimming plate 140 can be achieved, thereby improving the contrast of the image displayed by the second display panel 50 of the display device 1 to which the optical splitter module 10 is applied.

[0091] Furthermore, when the second driving part 1421 corresponding to the second dimming unit 140a is loaded with a second control voltage, the second electrowetting fluid 144 in the second dimming unit 140a adheres to the two second spacers 1431 and the second driving part 1421 in the second dimming unit 140a, so that the second dimming unit 140a has the shielding state.

[0092] When the second driving part 1421 corresponding to the second dimming unit 140a is loaded with the second control voltage, the second electrowetting liquid 144 in the second control unit adheres to the two second spacers 1431 and the second driving part 1421 in the second dimming unit 140a. Therefore, there is no gap between the two second spacers 1431 of the second dimming unit 140a, and the light irradiated to the second dimming unit 140a cannot pass through the second electrowetting liquid 144, so that the second dimming unit 140a is in the shielding state.

[0093] In one embodiment, when the second driving unit 1421 is loaded with a second control voltage, the second control voltage may be, but is not limited to, 5V to 30V. This allows the second control voltage to have a better control effect on the second electrowetting fluid 144 .

[0094] It can be seen that by loading the second control voltage on the second driving part 1421, the second dimming unit 140a corresponding to the second driving part 1421 can be in a shielded state; by not loading the second control voltage on the second driving part 1421, the second dimming unit 140a corresponding to the second driving part 1421 can be in a light-transmitting state, thereby enabling precise control of the second dimming unit 140a. In other words, when the light emitted by the splitter module 10 is irradiated on the second dimming plate 140, the partitioned control of the light emitted from the second dimming plate 140 can be achieved, thereby improving the contrast of the display image of the second display panel 50 of the display device 1 to which the splitter module 10 is applied.

[0095] Furthermore, referring to 8 , the second dimming plate 140 further includes a second film layer 145. The second film layer 145 is disposed on the side of the second driving layer 142 facing away from the second substrate 141. The second film layer 145 includes a plurality of second portions 1451, each of which is disposed corresponding to the second driving portion 1421. When the second driving portion 1421 is not subjected to the second control voltage, the second portion 1451 is a hydrophobic portion; when the second driving portion 1421 is subjected to the second control voltage, the second portion 1451 is a hydrophilic portion.

[0096] When the second driving part 1421 is not loaded with the second control voltage, the second part 1451 is a hydrophobic part, that is, the second part 1451 exhibits a hydrophobic property. Therefore, when the second driving part 1421 is not loaded with the second control voltage, the second electrowetting liquid 144 is adhered to form one of the two second spacers 1431 in the second dimming unit 140a, and has a gap with the other of the two second spacers 1431, so that the second dimming unit 140a is in a light-transmitting state.

[0097] When the second driving part 1421 is loaded with the second regulating voltage, the property of the second part 1451 is changed, so that the second part 1451 becomes hydrophilic. Therefore, the second part 1451 is a hydrophilic part.

[0098] Therefore, when the second driving unit 1421 is loaded with the second control voltage, the second electrowetting fluid 144 adheres to the two second spacers 1431 in the second dimming unit 140 a and the second driving unit 1421 , so that the second dimming unit 140 a is in the shielding state.

[0099] It can be seen that the second dimming unit 140a provided in the embodiment of the present application includes a second film layer 145, and the second film layer 145 includes multiple second parts 1451. The second driving part 1421 is not loaded with the second control voltage or loaded with the second control voltage so that the second part 1451 is hydrophobic or hydrophilic. When the second part 1451 is a hydrophobic part or a hydrophilic part, the effect on the second electrowetting liquid 144 is different, so that the second dimming unit 140a has a light-transmitting state or a shielding state.

[0100] Further, see Figure 6 and Figure 8 The second dimming plate 140 also includes a second optical film 146. The second optical film 146 is disposed (e.g., by bonding) on ​​one side of the fourth surface 141b of the second substrate 141. The second optical film 146 may be an antireflection film or a brightness-averaging film. The inclusion of the second optical film 146 in the second dimming plate 140 improves the quality of light emitted from the second dimming plate 140.

[0101] Further, see Figure 7 The optical splitter module 10 further includes a packaging frame 150, which is also called a supporting structure. The packaging frame 150 is used to package the light source 110, the light guide plate 120, the first dimming plate 130 and the second dimming plate 140.

[0102] In combination with the spectrometer module 10 provided in the previous embodiment, it can be seen that in the display device 1 provided in the embodiment of the present application, the first display panel 30 is arranged on the side of the first dimming plate 130 away from the second dimming plate 140; the second display panel 50 is arranged on the side of the second dimming plate 140 away from the first dimming plate 130.

[0103] In one embodiment, the first display panel 30 includes a plurality of first pixels, the first cavity 133a is provided corresponding to at least one first pixel unit, the second display panel 50 includes a plurality of second pixels, and the second cavity 143a is provided corresponding to at least one second pixel unit.

[0104] In one embodiment, the structures of the first dimming plate 130 and the second dimming plate 140 are completely identical, so as to improve the production efficiency of manufacturing the light splitting module 10 and further improve the production efficiency of manufacturing the display device.

[0105] The following is a detailed description of the method for preparing the optical splitter module 10 provided in the embodiment of the present application. The method for preparing the optical splitter module 10 can be used to prepare the optical splitter module 10 provided in the previous embodiment. Accordingly, the optical splitter module 10 provided in the previous embodiment can be prepared using the method for preparing the optical splitter module 10 provided in the embodiment of the present application.

The method for preparing the optical splitter module 10 includes but is not limited to S100, S200, S300, S400, S500 and S600, which are described in detail as follows.

[0107] S100 , providing a substrate 610 .

[0110] S300, forming a spacer layer 630 on the driving layer 620, the spacer layer 630 includes a plurality of spacers 631 arranged at intervals, and a receiving cavity 630a is formed between adjacent spacers 631. For a detailed structure, please refer to Figure 11 (c) in the.

[0111] S400: dripping electrowetting liquid 640 into the receiving cavity 630a to form a dimming plate 650. The dimming plate 650 can be used as the first dimming plate 130 and the second dimming plate 140. For the detailed structure of the dimming plate 650, please refer to Figure 11 (d) in.

[0112] S500, providing a light guide plate 120, and setting the light guide plate 120 on a spacer layer 630 of a dimming plate 650. Figure 11 (e) in .

[0113] S600, take another dimming plate 650, and set the other dimming plate 650 on the other side of the light guide plate 120. Figure 11 (f) and Figure 11 (g) in.

[0114] In this way, one dimming plate 650 can serve as the first dimming plate 130, and the other dimming plate 650 can serve as the second dimming plate 140. Accordingly, the driving layer 620 in the one dimming plate 650 is the first driving layer 132, the spacer layer 630 in the one dimming plate 650 is the first spacer layer 133, the receiving cavity 630a in the one dimming plate 650 is the first cavity 133a, and the electrowetting fluid 640 in the one dimming plate 650 is the first electrowetting fluid 134. Accordingly, the driving layer 620 in the other dimming plate 650 is the second driving layer 142, the spacer layer 630 in the other dimming plate 650 is the second spacer layer 143, the receiving cavity 630a in the other dimming plate 650 is the second cavity 143a, and the electrowetting fluid 640 in the other dimming plate 650 is the second electrowetting fluid 144.

[0115] In summary, the method for preparing the optical splitter module 10 provided in the embodiment of the present application, wherein the first dimming plate 130 and the second dimming plate 140 have the same structure, can be prepared using relative processes, and can improve production efficiency. In addition, the optical splitter module 10 prepared by the method for preparing the optical splitter module 10 provided in the embodiment of the present application can control the first dimming unit 130a of the first dimming plate 130 and the second dimming unit 140a of the second dimming plate 140, so that the optical splitter module 10 has a first single-sided light-emitting mode in which light can be emitted only from the first dimming plate 130 and not from the second dimming plate 140; a second single-sided light-emitting mode in which light can be emitted only from the second dimming plate 140 and not from the first dimming plate 130; and a double-sided light-emitting mode in which light can be emitted from both the first dimming plate 130 and the second dimming plate 140. When the light splitting module 10 is applied to the display device 1 , the display device 1 can have multiple display modes, thereby being able to meet display requirements in different scenarios and having a wider range of application scenarios.
