[0049] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0050] The terms "first", "second", "third" in the embodiments of the present application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second", "third" can expressly or implicitly include at least one of the features. In the description of the present application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0051] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0052] See also Figures 1 to 3 , Figure 1 is a schematic structural diagram of a first embodiment of a display device provided by the present application, Figure 2 is a schematic structural diagram of a second embodiment of a display device provided by the present application, Figure 3It is a structural schematic diagram of the third embodiment of the display device provided in the present application.

[0053] The present application provides a display device 100, which includes a display panel 2 and a dimming component 1, wherein the dimming component 1 includes a dimming control unit 10 and a driving unit 11, wherein the dimming control unit 10 is used to form collimated outgoing light, and the driving unit 11 is used to drive the dimming control unit 10 to deflect to adjust the deflection angle of the outgoing light of the display device 100, so that the outgoing light of the display device 100 has N different deflection angles in sequence, wherein N is a positive integer greater than or equal to 2. At the same time, all outgoing lights of the display device 100 have the same deflection angle. It should be noted that the deflection angle of the outgoing light of the display device 100 refers to the angle between the outgoing light and the collimated light perpendicular to the display panel 2, that is, the angle at which the outgoing light is deflected relative to the collimated light perpendicular to the display panel 2.

[0054] It can be understood that the present application sets the dimming component 1 to include a driving unit 11 and a dimming control unit 10, and the driving unit 11 drives the dimming control unit 10 to deflect to adjust the deflection angle of the output light of the display device 100, so that the output light of the display device 100 has N different deflection angles, and thus the display device 100 has N different viewing angles, that is, by adjusting the dimming component 1 to achieve the switching of multiple viewing angles of the display device 100, a true holographic display can be achieved with N different pictures. Specifically, the display panel 2 of the display device 100 can be a liquid crystal display panel or an active light-emitting display panel, which can be designed according to specific needs.

[0055] See also Figure 1 In one embodiment, the display panel 2 of the display device 100 is a liquid crystal display panel, and the display device 100 further includes a backlight module 3, which is used to provide backlight for the liquid crystal display panel. The backlight module 3 can be a direct-type backlight module or an edge-type backlight module, and can be designed as needed. Figure 1 As shown, in this embodiment, the dimming component 1 is arranged between the liquid crystal display panel and the backlight module 3. The backlight provided by the backlight module 3 first enters the dimming component 1, is adjusted by the dimming component 1 to form collimated light and has N different deflection angles in sequence, and then enters the liquid crystal display panel and is emitted, thereby realizing the adjustment of the deflection angle of the output light of the display device 100, so that the display device 100 has N different viewing angles, which is beneficial for the display device 100 to realize holographic display.

[0056] See also Figure 2 In another embodiment, the display panel 2 of the display device 100 is also a liquid crystal display panel, which is different from the first embodiment of the display device 100 in that the dimming component 1 of the display device 100 is arranged at a different position. Figure 2As shown, in this embodiment, the dimming component 1 is arranged on the light-emitting surface of the liquid crystal display panel, and the backlight module 3 is arranged on the side of the liquid crystal display panel away from the dimming component 1. The backlight provided by the backlight module 3 passes through the liquid crystal display panel and enters the dimming component 1 from the light-emitting surface of the liquid crystal display panel. The dimming component 1 adjusts the light so that the light emitted from the display device 100 after passing through the dimming component 1 becomes collimated light, and the emitted light of the display device 100 has N different deflection angles in sequence, so that the display device 100 has N different viewing angles, which is beneficial for the display device 100 to realize holographic display.

[0057] See also Figure 3 In another embodiment, different from the first and second embodiments of the display device 100, in this embodiment, the display panel 2 is an active light-emitting display panel, the display device 100 does not include the backlight module 3, and the display panel 2 can actively emit light without the need for the backlight module 3 to provide backlight. For example, the display panel 2 may include any display panel 2 such as LED, OLED, plasma, CRT, etc. to realize the self-luminescence of the display panel 2. Figure 3 As shown, the dimming component 1 is arranged on the light-emitting surface of the active light-emitting display panel. The light emitted from the light-emitting surface of the active light-emitting display panel enters the dimming component 1 and is adjusted by the dimming component 1 to form collimated light and has N different deflection angles in sequence, so that the display device 100 has N different viewing angles, which is conducive to the display device 100 to realize holographic display.

[0058] The following will take the first embodiment of the display device 100 as an example for description.

[0059] See also Figures 4 to 8 , Figure 4 is a structural schematic diagram of a first embodiment of a dimming component of a display device provided by the present application, Figure 5 yes Figure 4 The schematic diagram of the structure of the elastic body of the dimming component, the display panel and the backlight module provided, Figure 6 yes Figure 4 A schematic diagram of the structure of the dimming component provided is deflected to the right along a first direction, Figure 7 yes Figure 4 A schematic diagram of the structure of the dimming component provided is deflected to the left along a first direction, Figure 8 It is a structural schematic diagram of another implementation manner of the first embodiment of the dimming component of the display device provided in the present application.

[0060] See also Figure 4In this embodiment, the dimming component 1 includes a dimming control unit 10, a driving unit 11 and a connecting member 12. The connecting member 12 is used to connect the dimming control unit 10 and the driving unit 11. The driving unit 11 drives the connecting member 12 to periodically move or deform, thereby driving the dimming control unit 10 to deflect periodically, so that the output light of the display device 100 has N different deflection angles, and the output light is periodically transformed at the N different deflection angles in sequence. For example, the driving unit 11 drives the connecting member 12 to move or deform periodically to drive the adjustment control unit 10 to deflect periodically, so that the output light of the display device 100 has three different deflection angles in the first direction A1. The first direction A1 is the left-right direction of the display panel 2, that is, the horizontal direction. The three deflection angles are the first deflection angle, the second deflection angle and the third deflection angle from left to right along the first direction A1. The output light is periodically transformed at the three different deflection angles in sequence, that is, the output light is deflected from the first deflection angle to the second deflection angle and then to the third deflection angle, and then deflected to the second deflection angle via the third deflection angle and then deflected back to the position of the first deflection angle. This is a change cycle. The driving unit 11 drives the output light of the display device 100 to repeat the above three deflection angles many times to achieve periodic transformation. The driving unit 11 can also drive the adjustment control 10 to deflect in the second direction A2 by driving the connecting member 12, so that the emitted light of the display device 100 also has a plurality of different deflection angles in the second direction A2, and the second direction A2 is the up-down direction of the display panel 2, that is, the longitudinal direction parallel to the display panel 2. In other words, the driving unit 11 can drive the adjustment control 10 to deflect in the left-right direction and / or the up-down direction of the display panel 2. The driving unit 11 includes any one of a servo drive motor and a digital electromagnet driver.

[0061] Specifically, Figure 4As shown, the connecting member 12 includes an elastomer 121, and the elastomer 121 is made of a transparent elastic material to facilitate light to pass through the dimming component 1 and ensure the transmittance of light. For example, the elastomer 121 can be made of transparent rubber or other materials. A plurality of dimming controls 10 are evenly distributed in the elastomer 121 to ensure the uniformity of light passing through the dimming component. The elastomer 121 has a light incident surface 1213 and a light emitting surface 1214 that are relatively arranged. The shapes of the light incident surface 1213 and the light emitting surface 1214 can be any shape such as a rectangle or a square. In this embodiment, the shapes of the light incident surface 1213 and the light emitting surface 1214 are roughly rectangular. The driving unit 11 applies opposite shear forces to the light emitting surface 1214 and the light incident surface 1213 in the first direction A1 to drive the elastic body 121 to deform so as to drive the dimming control 10 to deflect. The shear forces applied to the light emitting surface 1214 and the light incident surface 1213 are opposite in direction and equal in magnitude to ensure that the light emitting surface 1214 and the light incident surface 1213 of the elastic body 121 can deform in opposite directions. It should be noted that the shear force only causes the light emitting surface 1214 and the light incident surface 1213 to deform in opposite directions, and does not change the original shape and size of the light emitting surface 1214 and the light incident surface 1213. The shape and size of the light emitting surface 1214 and the light incident surface 1213 remain the same. The shape of the dimming component 1 can be set to any shape such as a rectangle or a square corresponding to the shape of the display panel 2. The driving unit 11 can be set to one or more.

[0062] See also Figure 5 In one embodiment, the areas of the light incident surface 1213 and the light emitting surface 1214 of the elastic body 121 are larger than the cross-sectional areas of the display panel 2 and the backlight module 3, so as to ensure that the light incident surface 1213 can still cover the entire backlight module 3 after translation, or the light emitting surface 1214 can still cover the entire display panel 2 after translation. Figure 5 As shown, the areas of the light incident surface 1213 and the light emitting surface 1214 of the elastomer 121 are both larger than the cross-sectional areas of the display panel 2 and the backlight module 3. As shown by the dotted line in the figure, when the light incident surface 1213 moves to the left or to the right along the first direction A1, the light incident surface 1213 still completely covers the backlight module 3, so that the light emitted by the backlight module 3 can completely enter the dimming component 1 through the light incident surface 1213 for adjustment; when the light emitting surface 1214 moves to the left or to the right along the first direction A1, the light emitting surface 1214 still completely covers the display panel 2, so that the light after adjustment by the dimming component 1 can enter the display panel 2 through the light emitting surface 1214, ensuring that light enters each position of the display panel 2 to ensure the display performance of the display device 100.

[0063] Further, in this embodiment, the connecting member 12 further includes a first side plate 122 and a second side plate 123, the elastic body 121 has a first side surface 1211 and a second side surface 1212 which are arranged opposite to each other along the first direction A1, and the dimming component 1 includes two driving units 11, which are respectively arranged on both sides of the elastic body 121 along the first direction A1, and are respectively arranged to be spaced apart from the first side surface 1211 and the second side surface 1212. The first side plate 122 is rotatably arranged on the first side surface 1211 of the elastic body 121 along the first direction A1 and is connected to one driving unit 11 located on one side of the first side surface 1211 through a first connecting rod 126, and the second side plate 123 is rotatably arranged on the second side surface 1212 of the elastic body 121 along the first direction A1 and is connected to another driving unit 11 located on one side of the second side surface 1212 through a second connecting rod 127.

[0064] Specifically, the first side plate 122 and the second side plate 123 include a first rotating shaft 124 and a second rotating shaft 125, respectively. The two driving units 11 drive the first connecting rod 126 and the second connecting rod 127 to move, respectively. The first connecting rod 126 and the second connecting rod 127 drive the first side plate 122 and the second side plate 123 to rotate around the first rotating shaft 124 and the second rotating shaft 125, respectively, drive the first side surface 1211 and the second side surface 1212 of the elastic body 121 to deflect, and then drive the elastic body 121 to deform, so that the multiple adjustment controls 10 in the elastic body 121 are deflected. Specifically, the first side plate 122 and the second side plate 123 can rotate around the first rotating shaft 124 and the second rotating shaft 125 along the first direction A1, or along the second direction A2, so that the multiple adjustment controls 10 in the elastic body 121 can be deflected in the first direction A1, or in the second direction A2. It should be noted that the driving unit 11 drives the first connecting rod 126 and the second connecting rod 127 to move with equal displacements, that is, the first side plate 122 and the second side plate 123 rotate around the first rotating shaft 124 and the second rotating shaft 125 in the same direction and at the same angle, respectively, to ensure that the deflection angles of the first side surface 1211 and the second side surface 1212 of the elastomer 121 are equal, thereby ensuring that the deflection angles of the multiple adjustment controls 10 in the elastomer 121 are the same, ensuring that all the output light of the display device 100 has the same deflection angle at the same time, ensuring that the output light of the display device 100 is collimated light and the output light is more uniform, thereby improving the picture quality of the display device 100.

[0065] In this embodiment, the first rotating shaft 124 of the first side plate 122 and the second rotating shaft 125 of the second side plate 123 are arranged in parallel and at the same height. The first rotating shaft 124 is located on the midline of the first side surface 1211 of the elastomer 121 parallel to the display panel 2, that is, the first side plate 122 and the second side plate 123 rotate around the midline of the first side surface 1211 and the second side surface 1212 parallel to the display panel 2 respectively, so that the elastomer 121 located on the upper and lower sides of the first rotating shaft 124 and the second rotating shaft 125 are evenly subjected to force and move, and the light emitting surface 1214 and the light incident surface 1213 of the elastomer 121 move in opposite directions.

[0066] It can be understood that in other embodiments, the first rotation axis 124 and the second rotation axis 125 can be respectively located on any straight line of the first side surface 1211 and the second side surface 1212 parallel to the display panel 2, and the first rotation axis 124 and the second rotation axis 125 have the same height. For example, the first rotation axis 124 and the second rotation axis 125 can be respectively arranged at the position where the first side surface 1211 and the second side surface 1212 are connected to the light emitting surface 1214 of the elastic body 121, or at the position where the first side surface 1211 and the second side surface 1212 are connected to the light emitting surface 1214 of the elastic body 121. At the position where the light incident surface 1213 of the body 121 is connected, that is, the height of the first rotating shaft 124 and the second rotating shaft 125 is flush with the height of the light emitting surface 1214 or the light incident surface 1213, the first side plate 122 and the second side plate 123 rotate around the first rotating shaft 124 and the second rotating shaft 125 respectively, so that except for the light emitting surface 1214 or the light incident surface 1213 that is flush with the first rotating shaft 124 and the second rotating shaft 125, the rest of the positions of the elastic body 121 are deformed and deflected, thereby driving the adjustment control 10 in the elastic body 121 to deflect.

[0067] The number of the first connecting rod 126 and the second connecting rod 127 is equal, and can be set to one or more. For example, the number of the first connecting rod 126 and the second connecting rod 127 is set to two at the same time. The first side plate 122 and the second side plate 123 both have two opposite sides along the up-down direction. The opposite sides of the first side plate 122 are respectively connected to the driving unit 11 located on the first side 1211 through the two first connecting rods 126, and the opposite sides of the second side plate 123 are respectively connected to another driving unit 11 located on the second side 1212 through the two second connecting rods 127. The two driving units 11 simultaneously drive the two first connecting rods 126 and the two second connecting rods 127 to move, driving the light emitting surface 1214 and the light incident surface 1213 of the elastic body 121 to move in the opposite direction, thereby causing the adjustment control 10 in the elastic body 121 to deflect. Figure 6As shown, the driving unit 11 drives two first connecting rods 126 and two second connecting rods 127 simultaneously, so that the first side plate 122 and the second side plate 123 are respectively deflected to the right along the first direction A1 around the first rotating shaft 124 and the second rotating shaft 125, driving the light incident surface 1213 of the elastic body 121 to move to the left and the light emitting surface 1214 to move to the right, so that the multiple adjustment controls 10 in the elastic body 121 are synchronously deflected to the right, and the deflection angles of the multiple adjustment controls 10 are equal, so that the emitted light is deflected to the right along the first direction, with a deflection angle to the right along the first direction.

The driving unit 11 drives the first connecting rod 126 and the second connecting rod 127 to drive the translation layer 120 to move. The translation layer 120 causes the light emitting surface 1214 and the light incident surface 1213 to only move in opposite directions but their shapes do not change, thereby ensuring that the light emitting surface 1214 and the light incident surface 1213 will not be broken or damaged under the shear force of the first connecting rod 126 and the second connecting rod 127, thereby ensuring the display effect of the display device 100. In other embodiments, the translation layer 120 may not be disposed, and may be designed according to specific needs.

[0069] Specifically, the translation layer 120 may include a transparent plate 13 or a plurality of filaments. For example, the translation layer 120 includes a plurality of filaments, and the plurality of filaments may be spaced apart and arranged on the light incident surface 1213 and / or the light emitting surface 1214 of the elastomer 121, and closely connected to the light emitting surface 1214 and / or the light incident surface 1213 of the elastomer 121, so as to ensure the tensile strength of the light emitting surface 1214 and the light incident surface 1213. Optionally, the plurality of filaments may be arranged in parallel at equal intervals, i.e., evenly distributed, or may be arranged crosswise, for example, the plurality of filaments may be arranged crosswise in a mesh shape, so as to ensure the tensile strength of the light emitting surface 1214 and the light incident surface 1213, and also ensure the strength uniformity at each position of the light emitting surface 1214 and the light incident surface 1213. In other embodiments, the plurality of filaments may also be embedded in the elastomer 121 to ensure the tensile strength of the elastomer 121 as a whole. The filaments may include any one or more of nylon or steel wire.

[0070] The dimming control unit 10 includes a plurality of grid sheets, which are arranged in an array in the elastic body 121. The driving unit 11 drives the first side plate 122 and the second side plate 123 to rotate around the first rotation axis 124 and the second rotation axis 125 respectively, driving the plurality of grid sheets in the elastic body 121 to deflect synchronously, so that the light passing through the dimming component 1 becomes collimated light with N different deflection angles. Specifically, the plurality of grid sheets can be arranged in a single layer or in multiple layers, such as Figure 4 As shown, in one embodiment, the plurality of grid sheets are distributed in a single layer, and the plurality of grid sheets are evenly distributed in an array within the elastic body 121 .

[0071] In another embodiment, the plurality of grid sheets are distributed in multiple layers, each layer includes a plurality of grid sheets and the grid sheets in each layer are also distributed in an array. Figure 8 As shown, multiple grid sheets are distributed in double layers in the elastic body 121, and multiple grid sheets in the two layers are evenly distributed in an array. It can be understood that the number of layers of the grid sheets distributed in multiple layers can also be other numbers, for example, multiple grid sheets can also be any number such as three layers, four layers or five layers. The grid sheets located at the bottom layer can be silver, and the grid sheets located at the top layer can be black, so as to increase the utilization rate of light and ensure that the light adjusted by the dimming component 1 is more uniform. The size of the grid sheet is small, and the shape of the grid sheet can be sheet-shaped or tubular, and the material of the grid sheet can be metal or non-metal.

[0078] See also Fig.15 , Fig.15 It is a structural schematic diagram of a control circuit of a display device provided in the present application.

[0079] The present application also provides a control circuit 4 of a display device 100. The display device 100 may be the display device 100 described above. The display device 100 includes a display panel 2 and a dimming component 1. The dimming component 1 is used to form collimated emergent light and adjust the deflection angle of the emergent light of the display device 100. The control circuit 4 is used to control the display device 100 to realize holographic display. Fig.15As shown, the control circuit 4 includes an angle driving module 41 and a display driving module 42, the angle driving module 41 is used to output a light deflection driving signal to the dimming component 1, wherein the light deflection driving signal is used to drive the regulating component so that the output light of the display device 100 has N different deflection angles in sequence; N is a positive integer greater than or equal to 2; the display driving module 42 is used to obtain the 3D picture to be displayed and divide the 3D picture to be displayed into N sub-pictures with different viewing angles, each sub-picture includes viewing angle information and image information, and the viewing angle information of each sub-picture corresponds to a deflection angle, the display driving module 42 obtains the timing signals of the N deflection angles and then outputs the display driving signals of the N sub-pictures to the display panel 2, and the display driving signal is used to drive the display panel 2 to display the image information of the corresponding sub-picture at the time corresponding to the timing signal of the deflection angle.

[0080] It can be understood that the angle control module of the control circuit 4 outputs a light deflection drive signal to the dimming component 1, thereby controlling the dimming component 1 to adjust the emitted light so that it has N different deflection angles, and the display driving module 42 drives the display panel 2 to display the image information of the corresponding sub-screen at the time corresponding to the timing signal of the deflection angle, so that the display device 100 can display N different sub-screens at N different viewing angles, thereby realizing a true holographic display, ensuring that the pixel density of the sub-screen corresponding to each viewing angle will not decrease, and further ensuring that the resolution of the display device 100 will not decrease, thereby solving the problems in the prior art that the display device 100 cannot realize a true holographic display, the display device 100 has low pixels and low resolution, and improving the picture quality of the display device 100.

[0081] Furthermore, the light deflection driving signal output by the angle driving module 41 to the dimming component 1 is used to periodically drive the dimming component 1, so that the output light of the display device 100 periodically repeats N deflection angles, and the periodic change frequency of each deflection angle is greater than or equal to 24HZ, that is, the number of times each deflection angle is repeated per unit time is greater than or equal to 24 times, so as to ensure that the switching refresh frequency of the N sub-screens exceeds the visual persistence effect of the human eye, thereby realizing a dynamic full-viewing angle holographic display.

[0082] In one embodiment, the light deflection driving signal is used to periodically drive the dimming component 1 in the first direction A1, and the first direction A1 is the left-right direction of the display panel 2, that is, the horizontal direction. The light deflection driving signal periodically drives the dimming component 1 in the first direction A1, so that the output light of the display device 100 has N deflection angles along the first direction A1. In the same cycle, the output light of the display panel 2 can be deflected from the first side of the display panel 2 to the second side of the display panel 2 along the first direction A1, and then deflected from the second side back to the first side; or, in one cycle, it can first deflect along the first direction A1 to the first side of the display panel 2, then deflect back to the original position, then deflect to the second side of the display panel 2, and then deflect back to the original position again. One cycle of the deflection angle includes a complete deflection from the first side to the second side and a complete deflection from the second side to the first side, that is, it includes a complete deflection from the first side to the second side and a complete deflection from the second side to the first side. Among them, the one-way periodic change frequency of the deflection angle is greater than or equal to 12HZ, and the one-way here refers to a complete deflection process of the incident light from the first side to the second side or a complete deflection process from the second side to the first side, that is, the number of times each deflection angle of the incident light appears in the process from the first side to the second side per unit time is greater than or equal to 12 times, or the number of times it appears in the process from the second side to the first side is greater than or equal to 12 times, thereby ensuring that the refresh frequency of the sub-screen corresponding to each viewing angle of the display device 100 exceeds the visual persistence effect of the human eye, thereby realizing dynamic holographic display.

[0083] In another embodiment, the light deflection driving signal is used to periodically drive the dimming component 1 in the first direction A1 and the second direction A2 that intersect each other, respectively, the first direction A1 is the left-right direction of the display panel 2, that is, the horizontal direction, and the second direction A2 is the up-down direction of the display panel 2, that is, the longitudinal direction parallel to the display panel 2. In the same cycle, the emitted light of the display device 100 can first be deflected toward the first side of the display panel 2 along the first direction A1, then deflected back to the original position, then deflected toward the second side of the display panel 2, and then deflected back to the original position again; then, deflected toward the third side of the display panel 2 along the second direction A2, then deflected back to the original position, then deflected toward the fourth side of the display panel 2 along the second direction A2, and then deflected back to the original position, that is, in one cycle, the emitted light not only completes a complete deflection from the first side to the second side and a complete deflection from the second side to the first side, but also completes a complete deflection from the third side to the fourth side and a complete deflection from the fourth side to the third side. The one-way periodic variation frequency of the deflection angle in the first direction A1 and the one-way periodic variation frequency in the second direction A2 are both greater than or equal to 24HZ. It should be noted that the one-way in the first direction A1 mentioned here refers to the process of a complete deflection of the incident light from the first side to the second side and a complete deflection from the second side to the first side, that is, a round-trip process from the first side to the second side and then to the first side; the one-way in the second direction A2 refers to the process of a complete deflection of the incident light from the third side to the fourth side and a complete deflection from the fourth side to the third side, that is, a round-trip process from the third side to the fourth side and then to the third side. The one-way periodic change frequency is greater than or equal to 24HZ, that is, the number of times each deflection angle of the emitted light per unit time in the first direction A1 occurs in the round-trip process from the first side to the second side and then to the first side is greater than or equal to 24 times, and the number of times each deflection angle of the emitted light per unit time in the second direction A2 occurs in the round-trip process from the third side to the fourth side and then to the third side is greater than or equal to 24 times, thereby ensuring that the refresh frequency of the sub-screen corresponding to each viewing angle of the display device 100 exceeds the visual persistence effect of the human eye, thereby realizing dynamic holographic display.

[0088] Specifically, the light deflection driving signal is used to drive the dimming component 1. After the light deflection driving signal is output to the dimming component 1, the regulating component can be driven to deflect, so that the output light of the display device 100 has N different deflection angles in sequence, where N is a positive integer greater than or equal to 2. Further, the light deflection driving signal can periodically drive the regulating component, so that the output light of the display device 100 periodically repeats N deflection angles, where the periodic change frequency of the deflection angle is greater than or equal to 24HZ, which is convenient for subsequent dynamic holographic display.

Each sub-picture includes corresponding viewing angle information and image information, and the viewing angle information of each sub-picture corresponds to a deflection angle.

And the holographic display effect achieved by the control method of the display device 100 provided by the present application ensures that the pixel density of the sub-picture corresponding to each viewing angle will not be reduced, thereby ensuring that the resolution of the display device 100 will not be reduced, solving the problem that the display device 100 in the prior art cannot achieve true holographic display, the display device 100 has low pixels and low resolution, and improving the picture quality of the display device 100.

[0095] It can be understood that in other embodiments, the display panel 2 can also be driven by a display driving signal to display image information of N sub-pictures at N viewing angles, and then the viewing angle information of the N sub-pictures and the timing signals of the N sub-pictures are obtained, and the dimming component 1 is driven to deflect by the light deflection driving signal, and the output light of the display device 100 is controlled to deflect to the corresponding deflection angle at the time corresponding to the timing signal of the sub-picture, so as to realize the display of the corresponding sub-picture at the deflection angle of the corresponding output light of the display device 100, so that the display device 100 can realize the display of N different sub-pictures at N different viewing angles, and realize true holographic display. That is, as long as the deflection angle of the output light at the same time is controlled to correspond to the viewing angle information of the sub-picture, different sub-pictures can be displayed at different viewing angles.
