Specifically, in the three-dimensional display device according to the embodiment of the present invention, as shown in fig. 4, each of the first sub-pixel columns 401 and each of the second sub-pixel columns 402 are arranged in a wave-shaped structure, and the turning point of each of the broken line segments forming the wave-shaped structure is located at the sub-pixel of the odd-numbered row.
In general, the layout of the naked-eye three-dimensional signal designed in the prior art is shown in fig. 5 for the sub-pixels arranged in the pixel arrangement shown in fig. 3b in the three-dimensional display device provided by the embodiment of the present invention. It can be seen that each first sub-pixel column 401 'and each second sub-pixel column 402' are arranged in a wave-shaped structure, and the turning point of each broken line segment constituting the wave-shaped structure is located at each row of sub-pixels.
Comparing fig. 5 with fig. 4, it can be seen that, compared with the layout of naked-eye three-dimensional signals as shown in fig. 4 provided by the embodiment of the present invention, the layout of three-dimensional signals in the prior art as shown in fig. 5 has a significant disadvantage: each column of subpixels lacks subpixels of one color, e.g., first column first subpixel column 401' in fig. 5 lacks green subpixels G as compared to first column first subpixel column 401 in fig. 4. That is, on the basis of the arrangement of the sub-pixels shown in fig. 3B provided by the embodiment of the present invention, by designing the arrangement of the three-dimensional signals shown in fig. 4, each sub-pixel column for displaying the left-eye view 1 and the right-eye view 2 includes a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B. Therefore, on one hand, the uniformity and the fineness of three-dimensional display are improved, and on the other hand, the effect of improving the visual resolution (PPI) of the sub-pixel rendering algorithm can be exerted to the maximum extent.

Further, in the three-dimensional display device according to the embodiment of the present invention, the light control part 202 forms the light blocking stripe N and the light transmitting stripe M shown in fig. 8 or 9 according to the display information of the display panel 201, that is, the voltage signal and the three-dimensional view arrangement mode, so as to ensure that the corresponding light enters the left eye or the right eye of the viewer, thereby implementing the three-dimensional display, as shown in fig. 10.
Further, in order to realize the continuous display of the view pixel information, as shown in fig. 11, the same view pixel information may be allocated to the neighboring sub-pixels, for example, the view pixel information 1 may be allocated to the neighboring red sub-pixel R1, blue sub-pixel B1, and green sub-pixel G1.
In the case where no voltage is applied to each of the first block electrode arrays 601, the second block electrode arrays 602, and the planar electrodes 208, almost the entire surface of the light control member 202 serves as a light transmitting portion, so that all light emitted from the display panel 201 can be transmitted through the light control member 202, thereby enabling two-dimensional display.
In the three-dimensional display device according to the embodiment of the present invention, the light control member 202 is used in a normally white mode in which light is transmitted without applying a voltage, but may be used in a normally black mode in which light is not transmitted without applying a voltage, and is not limited thereto.
In practical implementation, in the three-dimensional display device provided in the embodiment of the present invention, the material of the light adjusting layer 206 is a liquid crystal material or an electrochromic material.

The material of the bulk electrode 207 and the planar electrode 208 may be a transparent conductive material such as indium tin oxide, indium zinc oxide, graphene, and the like, and is not limited herein.
In addition, in order to realize that the display panel 201 displays images, as shown in fig. 2, the three-dimensional display device provided in the embodiment of the present invention generally further includes: polarizers 210 disposed at two sides of the display panel 201. The polarizer 210 may filter the passing light to form polarized light, thereby implementing image display.
Specifically, in the three-dimensional Display device provided in the embodiment of the present invention, the Display panel 201 may be a Liquid Crystal Display panel (LCD) or an electroluminescent Display panel (OLED), and certainly, may also be a Display panel with other Display modes, such as a quantum dot Display panel (QLED) or a Light-Emitting Diode Display panel (LED), which is not limited herein.

In a specific implementation, as shown in fig. 2, the three-dimensional display device provided in the embodiment of the present invention may further include: a transparent adhesive layer 212 disposed between the display panel 201 and the light-controlling member 202. On one hand, the light control component 202 can be fixed on the surface of the light-emitting side of the display panel 201 through the transparent adhesive layer 212, and on the other hand, the transparent adhesive layer 212 can reduce the reflection effect of the light control component 202 on the light emitted by the display panel 201, thereby improving the brightness of three-dimensional display. Preferably, the material of the transparent Adhesive layer 212 is Optical Clear Adhesive (OCA).
Generally, in the conventional three-dimensional display process, a crosstalk phenomenon in which a part of the left-eye view 1 enters the right eye of the viewer or a part of the right-eye view 2 enters the left eye of the viewer tends to occur.
Therefore, in order to effectively avoid the crosstalk phenomenon, as shown in fig. 2, the three-dimensional display device according to an embodiment of the present invention further includes: the visual tracking component (not shown in fig. 2) is used for tracking the relative position of the line of sight of the viewer and the display panel 201, and realizing that different light shading stripes and light transmission stripes are formed according to different positions of human eyes, so that the human eyes are positioned at an optimal viewing position at any time, the crosstalk of the three-dimensional display is ensured to be minimum, the continuous viewing angle is increased, and meanwhile, the moire effect accompanying the crosstalk is effectively reduced.
