[0022] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings and in conjunction with embodiments.

[0023] It should be noted that the terms "first", "second", and the like in the description and claims of the present disclosure and the above-described drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence.

[0028] The double-layer liquid crystal lens includes a first liquid crystal lens and a second liquid crystal lens arranged in layers.

[0029] According to whether the screen 1 is in a horizontal screen state or a vertical screen state, the working state of the first liquid crystal lens and / or the second liquid crystal lens is switched, so that the naked-eye three-dimensional display device displays three-dimensional images in the horizontal screen state or the vertical screen state.

[0030] By adopting the above technical solution, since the pixel unit of the screen is provided to include sub-pixels in the row direction and sub-pixels in the column direction, and each sub-pixel is further provided to include three primary colors, and the arrangement order of the three primary colors in each row is different, and the arrangement order of the three primary colors in each column is different, and the arrangement order of the three primary colors corresponding to a row and the three primary colors corresponding to a column is the same, in combination with the first liquid crystal lens and the second liquid crystal lens of the double-layer liquid crystal lens, in combination with the horizontal screen state or the vertical screen state of the screen, the working state of the first liquid crystal lens and / or the second liquid crystal lens is switched, so that the first liquid crystal lens and the sub-pixels in the row direction cooperate to image three-dimensional images, and the second liquid crystal lens and the sub-pixels in the column direction cooperate to image three-dimensional images, so that the naked-eye three-dimensional display device displays three-dimensional images in the horizontal screen state or the vertical screen state, thereby solving the problem of poor three-dimensional imaging effect after horizontal screen and vertical screen conversion in the related art.

[0031] In an embodiment, the first liquid crystal lens includes a first liquid crystal layer 5 and a first light-transmitting curing adhesive 2, and the second liquid crystal lens includes a second liquid crystal layer and a second light-transmitting curing adhesive 3.

[0032] In the horizontal screen state, the voltage is applied to the first liquid crystal layer 5 and no voltage is applied to the second liquid crystal layer, so that the refractive index of the first liquid crystal layer 5 and the first light-transmitting curing glue 2 is different, the refractive index of the second liquid crystal layer and the second light-transmitting curing glue 3 is the same, and the naked-eye three-dimensional display device displays the first three-dimensional image in the refractive row direction of the three primary colors.

[0033] In the vertical screen state, no voltage is applied to the first liquid crystal layer 5 and voltage is applied to the second liquid crystal layer, so that the refractive index of the first liquid crystal layer 5 and the first light-transmitting curing glue 2 is the same, the refractive index of the second liquid crystal layer and the second light-transmitting curing glue 3 is different, and the naked-eye three-dimensional display device displays the second three-dimensional image in the refractive column direction of the three primary colors.

[0034] In an embodiment, the first liquid crystal lens includes a first upper substrate 6 and a first lower substrate 7, and the second liquid crystal lens includes a second upper substrate and a second lower substrate, wherein the first liquid crystal layer 5 is located between the first upper substrate 6 and the first lower substrate 7, and the second liquid crystal layer is located between the second upper substrate and the second lower substrate, and the first upper substrate 6, the first lower substrate 7, the second upper substrate and the second lower substrate are provided with electrodes to apply voltage to the first liquid crystal layer 5 and the second liquid crystal layer.

[0035] The above will be explained in combination with the accompanying drawings:

[0036] FIG. 3 is a schematic view of the position relationship of the first light-transmitting curing glue and the second light-transmitting curing glue according to an embodiment of the present disclosure, in an exemplary embodiment, as shown in FIG. 3, the position relationship of the first light-transmitting curing glue 2 in the first liquid crystal lens and the second light-transmitting curing glue 3 in the second liquid crystal lens is used instead of the position relationship of the first liquid crystal lens and the second liquid crystal lens. Wherein, the first light-transmitting curing glue 2 is used for the screen 1 to present the first three-dimensional image in the horizontal screen state, and the first light-transmitting curing glue 2 fills the entire imaging area of the screen 1 in the horizontal screen direction of the screen 1. Wherein, the second light-transmitting curing glue 3 is used for the screen 1 to present the second three-dimensional image in the vertical screen state, and the second light-transmitting curing glue 3 fills the entire imaging area of the screen 1 in the vertical screen direction of the screen 1. That is, the extension direction of the first light-transmitting curing glue 2 and the second light-transmitting curing glue 3 is perpendicular to each other, and the first liquid crystal lens and the second liquid crystal lens are parallel to each other in the screen 1. The first light-transmitting curing glue 2 can be located above the second light-transmitting curing glue 3, or below the second light-transmitting curing glue 3. Therefore, the position relationship of the first liquid crystal lens and the second liquid crystal lens is the same, and the present disclosure will not be described here.

[0037] FIG. 4 is a structural schematic diagram of the first liquid crystal lens or the second liquid crystal lens according to an embodiment of the present disclosure. In an exemplary embodiment, the first liquid crystal lens is taken as an example for illustration as shown in FIG. 4. The first liquid crystal lens comprises a first upper substrate 6, a first liquid crystal layer 5, a first light-transmitting curing adhesive 2, and a first lower substrate 7. The first light-transmitting curing adhesive 2 is located between the first upper substrate 6 and the first lower substrate 7. For example, the first light-transmitting curing adhesive 2 is located on the side wall of the first upper substrate 6 facing the first lower substrate 7, or the first light-transmitting curing adhesive 2 is located on the side wall of the first lower substrate 7 facing the first upper substrate 6. The first liquid crystal layer 5 is located between the first light-transmitting curing adhesive 2 and the first upper substrate 6 or the first lower substrate 7. For example, in the case that the first light-transmitting curing adhesive 2 is located on the side wall of the first upper substrate 6 facing the first lower substrate 7, the first liquid crystal layer 5 is filled between the first light-transmitting curing adhesive 2 and the first lower substrate 7. In the case that the first light-transmitting curing adhesive 2 is located on the side wall of the first lower substrate 7 facing the first upper substrate 6, the first liquid crystal layer 5 is filled between the first light-transmitting curing adhesive 2 and the first upper substrate 6.

[0038] In the case that no voltage is applied to the first upper substrate 6 and the first lower substrate 7, no electric field is generated between the first upper substrate 6 and the first lower substrate 7. The liquid crystal molecules in the first liquid crystal layer 5 are rod-shaped or disc-shaped structures, which are arranged in a preset direction without the action of an electric field. Thus, the refractive index of the first liquid crystal layer 5 is the same as that of the first light-transmitting curing adhesive 2. In the case that a voltage is applied to the first upper substrate 6 and the first lower substrate 7, an electric field is generated between the first upper substrate 6 and the first lower substrate 7. At this time, under the action of the electric field, the electric field force acts on the dipole moment of the liquid crystal molecules, causing the orientation of the liquid crystal molecules to change, thereby changing the optical properties of the first liquid crystal layer 5, so that the refractive index of the first liquid crystal layer 5 is different from that of the first light-transmitting curing adhesive 2. Further, since the first upper substrate 6 and the first lower substrate 7 are both provided with electrodes, the polarity of the electrodes of the first upper substrate 6 and the first lower substrate 7 can be changed to change the electric field between the first upper substrate 6 and the first lower substrate 7, so as to adjust the refractive index of the first liquid crystal layer 5.

[0039] Similarly, the second liquid crystal lens comprises a second upper substrate, a second liquid crystal layer, a second light-transmitting curing glue 3, and a second lower substrate, wherein the second light-transmitting curing glue 3 is located between the second upper substrate and the second lower substrate. For example, the second light-transmitting curing glue 3 is located on the side wall of the second upper substrate facing the second lower substrate, or the second light-transmitting curing glue 3 is located on the side wall of the second lower substrate facing the second upper substrate. The second liquid crystal layer is located between the second light-transmitting curing glue 3 and the second upper substrate or the second lower substrate. For example, in the case that the second light-transmitting curing glue 3 is located on the side wall of the second upper substrate facing the second lower substrate, the second liquid crystal layer is filled between the second light-transmitting curing glue 3 and the second lower substrate. In the case that the second light-transmitting curing glue 3 is located on the side wall of the second lower substrate facing the second upper substrate, the second liquid crystal layer is filled between the second light-transmitting curing glue 3 and the second upper substrate.

[0040] In the case that no voltage is applied to the second upper substrate and the second lower substrate, no electric field is generated between the second upper substrate and the second lower substrate. The liquid crystal molecules in the second liquid crystal layer are rod-shaped or disc-shaped structures, which are arranged in a preset direction without the action of an electric field. Thus, the refractive index of the second liquid crystal layer is the same as that of the second light-transmitting curing glue 3. In the case that a voltage is applied to the second upper substrate and the second lower substrate, an electric field is generated between the second upper substrate and the second lower substrate. At this time, under the action of the electric field, the electric field force acts on the dipole moment of the liquid crystal molecules, causing the orientation of the liquid crystal molecules to change, thereby changing the optical properties of the second liquid crystal layer, so that the refractive index of the second liquid crystal layer is different from that of the second light-transmitting curing glue 3. Further, since the second upper substrate and the second lower substrate are both provided with electrodes, the polarity of the electrodes of the second upper substrate and the second lower substrate can be changed to change the electric field between the second upper substrate and the second lower substrate, so as to adjust the refractive index of the second liquid crystal layer.

[0041] Therefore, in the horizontal screen state, a voltage is applied to the first liquid crystal layer 5, and no voltage is applied to the second liquid crystal layer, so that the refractive index of the first liquid crystal layer 5 and the first light-transmitting curing glue 2 is different, and the refractive index of the second liquid crystal layer and the second light-transmitting curing glue 3 is the same, so as to refract the three primary colors in the column direction, and the naked-eye three-dimensional display device displays a first three-dimensional image;

[0042] In the vertical screen state, no voltage is applied to the first liquid crystal layer 5, and a voltage is applied to the second liquid crystal layer, so that the refractive index of the first liquid crystal layer 5 and the first light-transmitting curing glue 2 is the same, and the refractive index of the second liquid crystal layer and the second light-transmitting curing glue 3 is different, so as to refract the three primary colors in the row direction, and the naked-eye three-dimensional display device displays a second three-dimensional image. The first three-dimensional image and the second three-dimensional image display the same content, but there is a difference in display effect, for example, the proportions of the images are different.

[0043] In an exemplary embodiment, the electrode described above can be an ITO electrode. The full name of ITO electrode is Indium Tin Oxide electrode, which is a kind of transparent conductive film material, and can be applied to liquid crystal display (LCD), touch screen, solar cell, organic light emitting diode (OLED) and other electronic devices. The use of ITO electrode in the present disclosure can have the following advantages: high transparency: ITO film has very high transparency, and the transmittance of visible light can reach more than 90%, which makes it very suitable for devices that require transparent conductive layer. Conductive performance: ITO is a kind of n-type semiconductor material with high conductivity, which can be optimized by adjusting the ratio of indium and tin. Chemical stability: ITO film has good chemical stability and is not easy to be oxidized or corroded, which makes it maintain performance in various environments. Mechanical strength: ITO film has high hardness and can be attached to different substrate materials such as glass, plastic, etc., and is not easy to be scratched or damaged. Good adhesion: ITO film can be well attached to various substrate materials to form a uniform conductive layer. Easy to process: ITO can be prepared by sputtering, evaporation, chemical vapor deposition (CVD) and other methods, and can be patterned by photolithography and other processes to meet different application requirements. Environmentally friendly: ITO material does not contain harmful substances such as lead, which meets environmental protection requirements.

[0044] In an exemplary embodiment, the first upper substrate 6, the first lower substrate 7, the second upper substrate and the second lower substrate can be glass or PI (Polyimide).

[0045] In an embodiment, the cross-sectional pattern of the first light-transmitting curing adhesive 2 and the second light-transmitting curing adhesive 3 includes a plurality of cross-sectionally identical sub-patterns, wherein each sub-pattern is a symmetric pattern, so that one side of the sub-pattern is used to refract the first sub-pixel and the other side is used to refract the second sub-pixel, wherein the first sub-pixel and the second sub-pixel are adjacent sub-pixels, and the sub-pixels include three primary colors.

[0046] In an embodiment, the area of each sub-pattern of the first light-transmitting curing adhesive 2 contains the first sub-pixel and the second sub-pixel, wherein the first sub-pixel and the second sub-pixel are row-wise adjacent sub-pixels, and the sub-pixels include row-wise adjacent three primary colors.

[0047] In an embodiment, the area of each sub-pattern of the second light-transmitting curing adhesive 3 contains the first sub-pixel and the second sub-pixel, wherein the first sub-pixel and the second sub-pixel are column-wise adjacent sub-pixels, and the sub-pixels include column-wise adjacent three primary colors.

[0048] FIG. 5 is a schematic diagram of the correspondence between the first light-transmissive curing glue and the three primary colors according to an embodiment of the present disclosure. In an exemplary implementation, the first light-transmissive curing glue 2 is a plurality of continuous rows of structures, which are determined based on the sub-pixels in the row direction. For example, taking the first light-transmissive curing glue 2 in a row as an example for explanation and illustration when the screen 1 is in a landscape orientation. As shown in FIG. 3, the cross-sectional pattern of the first light-transmissive curing glue 2 includes a plurality of sub-patterns with the same cross section, each of which is a symmetrical pattern, so that one side of the sub-pattern is used to refract the first sub-pixel and the other side is used to refract the second sub-pixel, wherein the first sub-pixel and the second sub-pixel are adjacent sub-pixels in the row direction, and the sub-pixels include three primary colors adjacent in the row direction. As shown in FIG. 5, in the atlas layer 4 corresponding to the pixel unit, taking the first row in the upper left corner as the initial position, two continuous sub-pixels are determined from left to right, for example, the first group of RGB is the first sub-pixel, and the second group of RGB sequentially to the right is the second sub-pixel. In the pattern of the first light-transmissive curing glue 2, taking the first row in the upper left corner as the initial position, the position of the first first light-transmissive curing glue 2 is determined based on the first sub-pixel and the second sub-pixel, and the first first light-transmissive curing glue 2 can accommodate the first sub-pixel and the second sub-pixel. Similarly, based on the above manner, the second first light-transmissive curing glue 2, the third first light-transmissive curing glue 2, … in the first row are determined. Similarly, based on the above manner, based on the second row of the atlas layer 4 corresponding to the pixel unit, the second first light-transmissive curing glue 2, the second first light-transmissive curing glue 2, … in the second row of the pattern of the first light-transmissive curing glue 2 are determined. In this way, all the first light-transmissive curing glues 2 are determined. The number of the first light-transmissive curing glues 2 is determined based on the atlas layer 4 corresponding to the pixel unit, and the number of the atlas layer 4 corresponding to the pixel unit and the number of the primary colors can be determined based on the size, resolution, etc. of the screen 1.

[0049] For example, taking the first first light-transmissive curing glue 2 in the first row as an example for explanation and illustration. In the viewing angle of the screen 1 in the landscape orientation, the first light-transmissive curing glue 2 is a left-right symmetrical structure, wherein the left side of the first light-transmissive curing glue 2 is used to refract the second sub-pixel in the first row in the atlas layer 4 corresponding to the pixel unit, i.e. the second pixel obtained by the second group of RGB in the first row, so as to make the second sub-pixel carry the right eye information and refract into the right eye of the user. The right side of the first light-transmissive curing glue 2 is used to refract the first sub-pixel in the first row in the atlas layer 4 corresponding to the pixel unit, i.e. the first pixel obtained by the first group of RGB in the first row, so as to make the first sub-pixel carry the left eye information and refract into the left eye of the user. In combination with the case of applying voltage to the first liquid crystal layer 5, so as to present the first three-dimensional image in the landscape orientation through the cooperation of the first light-transmissive curing glue 2 and the first liquid crystal layer 5.

[0050] FIG. 6 is a schematic diagram of a corresponding relationship between the first light-transmissive curing adhesive and the three primary colors according to an embodiment of the present disclosure. In an exemplary embodiment, as shown in FIG. 6, the second light-transmissive curing adhesive 3 is in a multi-column continuous structure, which is determined based on the sub-pixels in the column direction. For example, in a landscape state of the screen 1, a second light-transmissive curing adhesive 3 in a column is taken as an example for explanation and illustration. As shown in FIG. 3, the cross-sectional pattern of the second light-transmissive curing adhesive 3 includes a plurality of sub-patterns with the same cross section, wherein each sub-pattern is a symmetrical pattern, so that one side of the sub-pattern is used to refract a first sub-pixel and the other side is used to refract a second sub-pixel, wherein the first sub-pixel and the second sub-pixel are column-adjacent sub-pixels, and the sub-pixels include column-adjacent three primary colors. As shown in FIG. 5, in the atlas layer 4 corresponding to the pixel unit, the first column in the upper left corner is taken as the initial position, and two consecutive sub-pixels are determined from top to bottom, for example, the first group of RGB is the first sub-pixel, and the second group of RGB sequentially counted downward is the second sub-pixel. In the pattern of the second light-transmissive curing adhesive 3, the first column in the upper left corner is taken as the initial position, the first second light-transmissive curing adhesive 3 is confirmed based on the first sub-pixel and the second sub-pixel, and the first second light-transmissive curing adhesive 3 can accommodate the first sub-pixel and the second sub-pixel. Similarly, based on the above-mentioned manner, the second second light-transmissive curing adhesive 3 and the third second light-transmissive curing adhesive 3 in the first column are confirmed. Similarly, based on the above-mentioned manner, the first second light-transmissive curing adhesive 3 and the second second light-transmissive curing adhesive 3 in the second column are confirmed in the second column of the pattern of the second light-transmissive curing adhesive 3 based on the second row of the atlas layer 4 corresponding to the pixel unit. In this way, all the second light-transmissive curing adhesives 3 are confirmed. The number of the second light-transmissive curing adhesives 3 is determined based on the atlas layer 4 corresponding to the pixel unit, wherein the atlas layer 4 corresponding to the pixel unit and the number of primary colors can be determined based on the size, resolution, etc. of the screen 1.

[0051] For example, taking the first second light-transmissive curing adhesive 3 in the first column as an example. In the landscape view of the screen 1, the second light-transmissive curing adhesive 3 is symmetrically structured in the upper and lower sides, wherein the upper side of the second light-transmissive curing adhesive 3 is used to refract the second sub-pixel in the first column of the pixel unit corresponding to the atlas layer 4, i.e. the second sub-pixel obtained by the first row and the second group of RGB, so as to refract the second sub-pixel carrying the right eye information into the right eye of the user (corresponding to the left eye and the right eye in the portrait view of the screen 1). The lower side of the second light-transmissive curing adhesive 3 is used to refract the first sub-pixel in the first column of the pixel unit corresponding to the atlas layer 4, i.e. the pixel obtained by the first row and the first group of RGB, so as to refract the first sub-pixel carrying the left eye information into the left eye of the user (corresponding to the left eye and the right eye in the portrait view of the screen 1). Since the screen 1 is in the landscape view, no voltage is applied to the second liquid crystal layer, and in combination with the case that the voltage is applied to the first liquid crystal layer 5, the refractive index of the first liquid crystal layer 5 and the first light-transmissive curing adhesive 2 is different, so as to refract the three primary colors in the row direction, so as to present the first three-dimensional image in the landscape view through the synergistic effect of the second light-transmissive curing adhesive 3 and the first liquid crystal layer 5.

[0052] In an embodiment, the first liquid crystal lens and the second liquid crystal lens are in a split structure or in an integrated structure.

[0053] Figure 7 is a structural schematic diagram of the screen in a landscape state, in an exemplary embodiment, as shown in Figure 7, at this time, in the viewing angle of the screen 1 in a landscape state, the pixel unit corresponding atlas layer 4 is located away from the user, the first light-cured adhesive 2 (first liquid crystal lens) is located close to the user, and the second light-cured adhesive 3 (second liquid crystal lens) is located between the pixel unit corresponding atlas layer 4 and the first light-cured adhesive 2. Among them, the first light-cured adhesive 2 (first liquid crystal lens) spreads along the row direction of the screen 1 to fill the display area of the screen 1, and the second light-cured adhesive 3 (second liquid crystal lens) spreads along the column direction of the screen 1 to fill the display area of the screen 1, and the extension direction of the first light-cured adhesive 2 (first liquid crystal lens) and the extension direction of the second light-cured adhesive 3 (second liquid crystal lens) are perpendicular. In the viewing angle of the screen 1 in a landscape state, a voltage is applied to the first liquid crystal layer 5, and an electric field is generated between the first upper substrate 6 and the first lower substrate 7 when the first upper substrate 6 and the first lower substrate 7 are applied with a voltage. At this time, under the action of the electric field, the electric field force acts on the dipole moment of the liquid crystal molecules, causing the orientation of the liquid crystal molecules to change, thereby changing the optical properties of the first liquid crystal layer 5, and the left side of the first light-cured adhesive 2 is used to refract the second sub-pixel of the first row of the pixel unit corresponding atlas layer 4, that is, the second pixel obtained by the first row second group of RGB, so as to make the second sub-pixel carry the right eye information and refract into the right eye of the user. The right side of the first light-cured adhesive 2 is used to refract the first sub-pixel of the first row of the pixel unit corresponding atlas layer 4, that is, the first pixel obtained by the first row first group of RGB, so as to make the first sub-pixel carry the left eye information and refract into the left eye of the user. In combination with the case of applying a voltage to the first liquid crystal layer 5, the first three-dimensional image in a landscape state is presented through the synergistic effect of the first light-cured adhesive 2 and the first liquid crystal layer 5. At the same time, no voltage is applied to the second liquid crystal layer, and no electric field is generated between the second upper substrate and the second lower substrate. The liquid crystal molecules in the second liquid crystal layer arrange according to the preset direction without the action of the electric field. The refractive index of the second liquid crystal layer and the second light-cured adhesive 3 is the same. Therefore, the naked eye three-dimensional display device displays the first three-dimensional image.

[0054] FIG. 8 is a structural schematic diagram of the screen 1 in a vertical screen state according to an embodiment of the present disclosure. In an exemplary embodiment, as shown in FIG. 8, at this time, in the view angle of the screen 1 in a horizontal screen state, the pixel unit corresponding atlas layer 4 is located away from the user, the first light-transmitting curing glue 2 (the first liquid crystal lens) is located close to the user, and the second light-transmitting curing glue 3 (the second liquid crystal lens) is located between the pixel unit corresponding atlas layer 4 and the first light-transmitting curing glue 2. The first light-transmitting curing glue 2 (the first liquid crystal lens) extends along the row direction of the screen 1 to fill the display area of the screen 1, the second light-transmitting curing glue 3 (the second liquid crystal lens) extends along the column direction of the screen 1 to fill the display area of the screen 1, and the extension direction of the first light-transmitting curing glue 2 (the first liquid crystal lens) is perpendicular to the extension direction of the second light-transmitting curing glue 3 (the second liquid crystal lens). In the view angle of the screen 1 in a vertical screen state, a voltage is applied to the second liquid crystal layer, and an electric field is generated between the second upper substrate and the second lower substrate when the voltage is applied to the second upper substrate and the second lower substrate. At this time, under the action of the electric field, the electric field force acts on the dipole moment of the liquid crystal molecules, causing the orientation of the liquid crystal molecules to change, thereby changing the optical properties of the second liquid crystal layer, so that the refractive index of the second liquid crystal layer and the refractive index of the second light-transmitting curing glue 3 are not the same. With the primary colors of the refractive column direction (here corresponding to the primary colors of the column item in the horizontal screen state), in the view angle, the left side (corresponding to the upper side in FIG. 7) of the second light-transmitting curing glue 3 is used to refract the second sub-pixel of the first column in the pixel unit corresponding atlas layer 4, i.e., the second sub-pixel obtained by the first row and the second group of RGB, so that the second sub-pixel carries the right eye information and is refracted into the right eye of the user. The right side (corresponding to the lower side in FIG. 7) of the second light-transmitting curing glue 3 is used to refract the first sub-pixel of the first column in the pixel unit corresponding atlas layer 4, i.e., the pixel obtained by the first row and the first group of RGB, so as to make the first sub-pixel carry the left eye information and be refracted into the left eye of the user. In combination with the case of applying a voltage to the first liquid crystal layer 5, the first three-dimensional image in the horizontal screen state is presented by the synergistic effect of the second light-transmitting curing glue 3 and the first liquid crystal layer 5. The liquid crystal molecules in the first liquid crystal layer 5 arrange according to the preset direction when there is no electric field. The refractive index of the first liquid crystal layer 5 and the first light-transmitting curing glue 2 is the same. Therefore, the naked eye three-dimensional display device displays the second three-dimensional image.

[0055] In an exemplary embodiment, the length of each primary color in the three primary colors is twice the width. Further, since each first light-transmitting curing glue 2 and second light-transmitting curing glue 3 contains two adjacent sub-pixels, i.e., contains 6 primary colors. Effectively improves the utilization rate of primary colors to improve the imaging effect.

[0056] It should be noted that the first light-transmissive curing adhesive 2 and the second light-transmissive curing adhesive 3 have the same area of the screen. In order to show the position relationship of the first light-transmissive curing adhesive 2 and the second light-transmissive curing adhesive 3, only a part of the first light-transmissive curing adhesive 2 and the second light-transmissive curing adhesive 3 is shown in FIGS. 1-8.

[0057] In summary, according to the present disclosure, since the pixel unit of the screen 1 includes row-direction sub-pixels and column-direction sub-pixels, and each sub-pixel includes three primary colors, and the arrangement order of the three primary colors in each row is different, and the arrangement order of the three primary colors in each column is different, and the arrangement order of the three primary colors in a corresponding row is the same as that in a corresponding column, in combination with the first liquid crystal lens and the second liquid crystal lens of the double-layer liquid crystal lens, in combination with the horizontal screen state or the vertical screen state of the screen 1, the working state of the first liquid crystal lens and / or the second liquid crystal lens is switched to make the first liquid crystal lens and the row-direction sub-pixels cooperate to image a three-dimensional image, and to make the second liquid crystal lens and the column-direction sub-pixels cooperate to image a three-dimensional image, so that the naked-eye three-dimensional display device displays a three-dimensional image in the horizontal screen state or the vertical screen state, thereby solving the problem of poor three-dimensional imaging effect after the horizontal screen and the vertical screen are converted in the related art. In this embodiment, a naked-eye three-dimensional display method is provided. FIG. 9 is a flowchart of the naked-eye three-dimensional display method according to the embodiment of the present disclosure, and FIG. 10 is a flowchart of a method for displaying a three-dimensional image in a horizontal screen state or a vertical screen state according to the embodiment of the present disclosure. As shown in FIGS. 9 and 10, the flowchart includes the following steps:

[0058] In step S901, the state of the screen 1 is detected. The pixel unit of the screen 1 includes row-direction sub-pixels and column-direction sub-pixels, each sub-pixel includes three primary colors, and the arrangement order of the three primary colors in each row is different, and the arrangement order of the three primary colors in each column is different, and the arrangement order of the three primary colors in a corresponding row is the same as that in a corresponding column.

[0059] In step S902, according to whether the screen 1 is in a horizontal screen state or a vertical screen state, the working state of the first liquid crystal lens and / or the second liquid crystal lens is switched to make the naked-eye three-dimensional display device display a three-dimensional image in the horizontal screen state or the vertical screen state.

[0060] In step S9021, in the horizontal screen state, a voltage is applied to the first liquid crystal layer 5, and no voltage is applied to the second liquid crystal layer, so that the refractive index of the first liquid crystal layer 5 and the first light-transmissive curing adhesive 2 is different, and the refractive index of the second liquid crystal layer and the second light-transmissive curing adhesive 3 is the same, so that the naked-eye three-dimensional display device displays a first three-dimensional image.

[0061] In the vertical screen state, the first liquid crystal layer 5 is not applied with voltage, and the second liquid crystal layer is applied with voltage, so that the refractive index of the first liquid crystal layer 5 and the first light-transmitting cured glue 2 is the same, the refractive index of the second liquid crystal layer and the second light-transmitting cured glue 3 is different, the three primary colors in the column direction are refracted, and the naked-eye three-dimensional display device displays a second three-dimensional image.

[0062] Through the above steps, the naked-eye three-dimensional display method provided by the present disclosure effectively solves the problem of poor three-dimensional imaging effect after the horizontal screen and the vertical screen are converted, by using the three primary colors in different arrangement sequences on the screen 1 and switching the working state of the liquid crystal lens according to the horizontal screen or the vertical screen state of the screen 1. In the horizontal screen state, the refractive index of the first liquid crystal layer 5 and the first light-transmitting cured glue 2 is different, and the refractive index of the second liquid crystal layer and the second light-transmitting cured glue 3 is the same, so that the three primary colors in the row direction are refracted, and the first three-dimensional image is displayed. In the vertical screen state, the refractive index of the first liquid crystal layer 5 and the first light-transmitting cured glue 2 is the same, and the refractive index of the second liquid crystal layer and the second light-transmitting cured glue 3 is different, so that the three primary colors in the column direction are refracted, and the second three-dimensional image is displayed.

[0063] Through this way of switching the working state of the liquid crystal lens, the present disclosure can refract the three primary colors in different directions according to the horizontal screen or the vertical screen state of the screen 1, so that the three-dimensional image is displayed in the horizontal screen and the vertical screen state. Compared with the problem of poor three-dimensional imaging effect after the horizontal screen and the vertical screen are converted in the background art, the present disclosure can better maintain the quality and effect of the three-dimensional image by adjusting the working state of the liquid crystal lens. Therefore, the present disclosure solves the problem of poor three-dimensional imaging effect after the horizontal screen and the vertical screen are converted in the liquid crystal lens scheme, and provides better naked-eye three-dimensional display effect.
