[0027] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Naked-eye 3D means that users can see 3D images without wearing additional equipment such as 3D glasses, AR glasses, helmets, etc. The main method of naked-eye 3D display is to set a matching grating in front of or behind the display device. The grating includes slit grating and cylindrical lens grating. Due to the serious brightness loss of slit grating and low light utilization rate, cylindrical lens grating is currently mainly used.

[0030] The lenticular lens is also called a double convex lens or a micro-cylindrical lens. The principle of the lenticular lens is:

[0031] The pixels of the image under each cylindrical lens are divided into several sub-pixels. The object focal plane of the cylindrical lens is just located on the light-emitting surface of the two-dimensional display device. Each cylindrical lens corresponds to several sub-pixels. The light emitted by these sub-pixels will be projected to a pre-set area in space after being refracted through the lens. Therefore, when the two eyes watch the display screen from different angles, they will see different sub-pixels. The left eye and the right eye can receive different image information at the same time, thus producing a three-dimensional effect.

[0032] However, the 3D naked-eye display effect in existing devices is poor and cannot achieve realistic effects.

[0033] Please see Figure 1-2 , a display device, comprising a first display panel and a light adjustment component arranged on a light emitting side of the first display panel, the light adjustment component comprising:

[0034] A substrate 1, wherein a first surface 101 of the substrate 1 that is arranged opposite to the first display panel 2 is a transparent structure, and the first surface 101 is configured as a naked-eye 3D observation surface;

[0035] A cylindrical lens array 5 is disposed inside the substrate 1 near the second surface 102 of the display panel, and the cylindrical lens array 5 is configured to adjust the light emitted by the first display panel 2;

[0036] A display structure is disposed on at least one inner side surface of the substrate 1 adjacent to the second surface 102 . The display structure includes a second display panel 3 and a light guide plate 4 matched with the first display panel 2 .

[0037] In the embodiment of the present application, the first display panel 2 is fixedly arranged on the outer surface of the substrate 1. The cylindrical lens array 5 is attached to the inner surface of the substrate 1, and is used to modulate the light emitted from the display panel and project it to a pre-set area in the space, thereby providing a realistic 3D visual effect.

[0038] One side of the cylindrical lens array 5 is a plane, and the other side is composed of a plurality of convex curved surfaces, and the plane is attached to the inner surface of the substrate 1 by optical adhesive or the like. The cylindrical lens array 5 can be regarded as a combination of a plurality of plano-convex cylindrical lenses arranged side by side, each of which has a longitudinal axis, and the longitudinal axes of these plano-convex cylindrical lenses are parallel to each other, and the specific number can be increased or decreased as the case may be.

[0039] It should be noted that display panels and light guide structures can be added to the three inner walls of the container base 1 connected to the first surface 101 to extend the three-dimensional scene as much as possible and make the main scene more obvious. When the observer observes the first surface 101 in the forward direction, the bottom surface 103 has a larger visual area within the observer's visual range. Therefore, when setting the second display panel 3, it can be set on the bottom surface 103 first. Of course, when setting it specifically, it can be adjusted according to different functions and display effects.

[0040] In the embodiment of the present application, liquid is disposed inside the substrate 1, and the refractive index of the liquid is greater than 1. In a container filled with liquid (the liquid may be any liquid with a refractive index greater than 1, and the higher the refractive index, the better), the image displayed by the display module behind the container can be moved forward, such as Figure 3 As shown, if the module displays multi-view information, the stereoscopic part can be brought forward to make the stereoscopic effect more obvious.

[0041] It should be noted that in the embodiment of the present application, when the display device is used in a fish tank, the liquid inside the base 1 can be water. When used in other display devices, other liquids with high refractive index can also be selected. In the embodiment of the present application, there is no limitation on the filling material in the base 1. The filling material in the base 1 can also include other fluid materials or solids of polymer materials. In specific applications, it can be selected according to different display devices. In the embodiment of the present application, a fish tank is used as an example.

[0042] When an observer observes the first surface 101 from the front, he finds that the joint between the rear wall and the bottom surface 103 is obvious. Figure 4As shown, the floating effect of the image is affected, so it is necessary to weaken this boundary and add a display at the bottom to extend the image boundary to ensure that the floating of the three-dimensional image is not affected. Therefore, in the embodiment of the present application, the seam 6 between the second surface 102 and the adjacent inner side surface is uniformly transitioned.

[0043] It should be noted that in the embodiment of the present application, "even transition" means smooth, flat and without any concave-convex structure or part. Even transition at the joint 6 means that the surface of the joint 6 is smooth, flat and without any concave-convex structure or part on the surface, for example, smooth, flat planes, arc surfaces, and circular surfaces all belong to "even transition".

[0044] In one embodiment of the present application, the joint 6 between the second surface 102 and the adjacent inner side surface is uniformly transitioned by adhesive. The joint 6 is filled with transparent optical adhesive or other transparent polymer materials to achieve uniform transition between the second surface 102 and the adjacent inner side.

[0045] It should be noted that, because the visual area of ​​the bottom surface 103 is larger within the visual range of the observer, the joint 6 between the bottom surface 103 and the first surface 101 of the rear wall is obvious, therefore, considering setting the second display panel 3 on the bottom surface 103 and performing uniform transition treatment on the joint 6 of the bottom surface 103. In order to improve the observation effect of the observer at each position, each joint 6 connecting the first surface 101 with other surfaces can be weakened, and the boundary weakening method can adopt a combination of different methods.

[0046] In one embodiment of the present application, the joint 6 between the second surface 102 and the adjacent inner side surface is rounded to achieve uniform transition. The rounding method is not limited to the first surface 101 and the adjacent surface being formed by integral molding, and the rounding between the second surface 102 and the adjacent inner side surface can also be formed by other processing methods.

[0047] In one embodiment of the present application, the angle between the second surface 102 and the adjacent inner side surface is greater than 90°. It should be noted that, since the visual area of ​​the bottom surface 103 is larger within the visual range of the observer, the visual area of ​​the bottom surface 103 is further increased by considering the second display panel 3 being arranged on the bottom surface 103 and increasing the angle between the first surface 101 and the bottom surface 103. In order to improve the observation effect of the observer at each position, the angle between the first surface 101 and other surfaces can be appropriately enlarged, and the visual area of ​​the bottom surface 103 can be further guaranteed by reducing the angle of other side edges.

[0048] Furthermore, in the embodiment of the present application, a plurality of prisms 7 are disposed on the light guide plate 4 , the first side edge 8 extends from the inner side surface of the base 1 toward the first surface 101 , and the second side edge 9 extends from the inner side surface of the base 1 toward the second surface 102 .

[0049] The first side edge 8 is a total reflection surface, and the second side edge 9 is a light emitting surface; the length of the first side edge 8 is greater than the length of the second side edge 9 .

[0050] It should be noted that, in the embodiment of the present application, the cross section of the prism 7 is preferably triangular, the bottom edge of the prism 7 is connected to the inner side of the substrate 1, and the remaining two sides are respectively a first side edge 8 and a second side edge 9, the bottom edge is used to allow the light emitted by the second display panel 3 to be incident on the prism 7, and the first side edge 8 is used to totally reflect the light incident on the prism 7, and the totally reflected light is transmitted to the substrate 1 through the second side edge 9. In the embodiment of the present application, by extending the length of the first side edge 8, the total reflection area is increased, and the light reflection efficiency is improved.

[0051] In the embodiment of the present application, the material of the prism 7 is a light-transmissive glass material or a polymer material (e.g., PMMA; polymethyl methacrylate). In specific settings, the inclination angles of the first side 8 and the second side 9 can be set differently to achieve different focusing effects to show different display effects.

[0052] It is worth noting that the shape of the prism 7 is not specifically limited in the embodiment of the present application, and other shapes may be included while achieving a 3D display effect, such as a cross-sectional shape of a trapezoid, a square, a polygon, etc. The shape of the first side 8 and the second side 9 may be a straight line or a curve, and the edge line may be an arc, a sine curve, a cosine curve, a wavy line, or a free curve.

[0053] The present application provides a naked-eye 3D electronic device, characterized in that it includes any display device as described above.

[0054] In an embodiment of the present application, the base 1 of the display device is made of glass material and is filled with water, in which fish or aquatic plants are placed. By adding real objects corresponding to the display scene as reference objects in the base 1 container, the virtual and the real are combined to make the virtual stereoscopic image more convincing.

[0055] The first display panel 2 can be used to display a theme picture, and the second display panel 3 can display auxiliary pictures, such as corals, water plants, and gravel, so as to echo the theme picture and further improve the display effect.

[0056] In the display device provided by the present application, a first display panel 2 is firstly arranged on the back of the substrate 1 as the main screen for 3D display, and a cylindrical lens array 5 film is pasted on the first surface 101, so that the "image plane" of the main screen is located on the "focal plane" of the lens, so that the pixels of the image under each cylindrical lens are divided into several sub-pixels, and projected and magnified at a certain angle in different directions. Since human eyes have different visual angles, 3D visual effects can be obtained by repeatedly projecting different sub-pixels.

[0057] At the same time, by arranging a second display panel 3 and a light guide plate 4 on the side, the second display panel 3 can display other auxiliary images on the one hand, and can also assist the first display panel 2 to improve the image quality, especially the color saturation, and can assist the first display panel 2 to obtain a sufficiently wide color gamut.
