[0019] To further understand the present utility model, the preferred implementation schemes of the present utility model will be described below in conjunction with embodiments. However, it should be understood that these descriptions are only for further explaining the features and advantages of the present utility model, rather than limiting the claims of the present utility model.

[0020] The description of this part only focuses on several typical embodiments, and the present utility model is not limited to the scope described in the embodiments. The mutual replacement of some technical features of the same or similar prior art means and the embodiments is also within the scope of description and protection of the present utility model.

[0021] "Connection" in the specification includes both direct connection and indirect connection.

[0022] The present utility model discloses an enhanced 3D effect display device. Figure 1 It is a schematic structural diagram of an enhanced 3D effect display device in an embodiment of the present utility model; please refer to Figure 1 , the enhanced 3D effect display device includes: a display device 1, a high refractive index transparent material 2, and a depth cue auxiliary mark 3; the high refractive index transparent material 2 is disposed on one side of the display device 1 and can refract the information displayed by the display device 1; the depth cue auxiliary mark 3 is disposed on the high refractive index transparent material 2, and the depth cue auxiliary mark 3 is a non-transparent substance.

[0023] The image content displayed on the display device is refracted by a transparent material with a high refractive index. According to the principle of light refraction, what the user sees is a virtual image formed by refraction, and the virtual image is located in front of the display device and in the middle of the high-refractive-index material, thus forming a 3D effect of the image popping out of the screen. At the front end of the high-refractive-index material close to the user and the rear end close to the display device, there are depth cue assist marks, which can form a depth contrast when the user views the virtual image formed by refraction, further enhancing the 3D visual effect of the virtual image hovering in the middle of the high-refractive-index material.

[0024] In an embodiment of the present invention, the display device 1 is a 2D display device or a 3D display device. For example, the display device 1 may include at least one of an LCD display screen, a naked-eye 3D display screen, a polarized 3D display screen, an active 3D display screen, etc.

[0025] The high-refractive-index transparent material 2 is a glass material with a refractive index above 1.7 and a light transmittance above 90% (the thickness can be 30 mm to 100 mm, such as 50 mm). The display device 1 and the high-refractive-index transparent material 2 can be fixed by a physical mechanical structure or bonded and fixed by an optical adhesive.

[0026] The depth cue assist mark 3 is a pigment printed on the high-refractive-index transparent material 2 or / and a light-emitting lamp strip installed on the high-refractive-index transparent material 2. The depth cue assist mark 3 is provided at the front end of the high-refractive-index transparent material close to the user and the rear end close to the display device.

[0027] In an embodiment of the present invention, the display device 1 is a naked-eye 3D display device, and the user can see the 3D effect without wearing any auxiliary equipment. The naked-eye 3D display device can perform image splitting on the content on the liquid crystal display panel by fully laminating a grating in front of the liquid crystal display panel. The content on the liquid crystal display panel is 3D video content processed by a set algorithm, which matches the optical characteristics of the fully laminated grating in front of the liquid crystal display panel, so that the user's left eye only sees the content belonging to the left eye, the user's right eye only sees the content belonging to the right eye, and the left eye and the right eye simultaneously see content with parallax, thus forming a 3D stereoscopic visual effect.

[0028] The high-refractive-index transparent material uses ultra-white glass with a refractive index of 1.7 and a light transmittance of 90%, and the thickness is 50 mm. The depth cue assist mark 3 is printed by screen printing, and white strip marks are screen-printed on the upper and lower surfaces of the ultra-white glass respectively. The naked-eye 3D display module and the ultra-white glass are bonded by OCA optical adhesive. Considering the large weight of the ultra-white glass, the ultra-white glass is supported and fixed through structural design to ensure the relative fixation of the naked-eye 3D display module and the ultra-white glass.

[0029] Figure 2 Schematic diagram of the refraction principle of the 3D effect enhancement display device in an embodiment of the present utility model; please refer to Figure 2 , the refraction of two light rays occurs at four points A, B, C, and D, and the incident angle i is greater than the refraction angle r, and the refractive index n of the three high refractive index materials satisfies the following formula:

[0030]

[0031] From this, the refracted light rays at points A, B, C, and D in Figure 2 can be drawn. According to the principle of light propagation, the user sees an image on the straight extension lines of points A and C, that is, the virtual image is in the high refractive index material 2.

[0032] In summary, the 3D effect enhancement display device proposed by the present utility model utilizes the principle of light refraction. By combining a transparent material with a high refractive index with the display device, the 3D display effect of the 3D display device can be significantly enhanced.
