Description

Technical Field

[0001] The present invention relates to display technology, and more particularly, to stereoscopic display technology. Background Art

[0002] Stereoscopic display technology is a display technology that can achieve true reproduction of stereoscopic scenes. It can provide different parallax images to the human eye, so that people can have stereoscopic vision. Traditional stereoscopic display devices have a single imaging depth, which can easily cause visual fatigue. The present invention proposes a stereoscopic display device based on a flexible screen, which can provide multiple imaging depths, thereby reducing visual fatigue. Summary of the invention

[0003] The present invention proposes a stereoscopic display device based on a flexible screen. Figure 1 The figure is a schematic diagram of the structure of the 3D display device based on the flexible screen. The 3D display device based on the flexible screen is composed of a front clamp, a rear clamp, a flexible display screen and a cylindrical lens grating.

[0004] For further information, please refer to Figure 1 The front clamp and the rear clamp are made of transparent material, and both have periodic curved surface structures in the vertical direction, and the periodic curved surface structures can be engaged with each other.

[0005] For further information, please refer to Figure 1 The flexible display screen is placed between the front clamp and the rear clamp. After the front clamp and the rear clamp are engaged, it has the same periodic curved surface structure as the front and rear clamps.

[0006] For further information, please refer to Figure 2 , the flexible display is used to provide parallax composite images, and the texture units from different parallax images are arranged alternately in columns in the horizontal direction. Please refer to Figure 3 ,The texture unit in each column on the flexible display consists of several pixels arranged in the horizontal direction.

[0007] For further information, please refer to Figure 2 The cylindrical lens grating is placed in front of the flexible display screen, which can project texture units of different parallax images to different viewpoints. When the human eyes are at different viewpoints, they can see the corresponding parallax images, thus generating stereoscopic vision.

[0008] For further information, please refer to Figure 4 Because the flexible display screen has a periodic curved surface structure in the vertical direction, the distances from the texture units of different vertical heights in the period to the cylindrical lens grating are different. According to the lens imaging formula, the images formed by these texture units with different object distances should have different image distances, so the texture units of different vertical heights in the period can be used to represent image information of different depths.

[0009] Optionally, the texture units on the flexible display screen can be imaged by a cylindrical lens grating.

[0010] Optionally, the texture units on the flexible display screen can be formed into a virtual image through a cylindrical lens grating.

[0011] In summary, when a viewer views a parallax image, because texture units at different heights within a period on the flexible display screen have different image distances, the present invention can provide image display at multiple different depths, thereby reducing visual fatigue.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0022] In the description of the embodiments of the present invention, it should be noted that the terms “first”, “second”, etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance. Example

[0023] Figure 1 The schematic diagram of the structure of a 3D display device based on a flexible screen provided in this embodiment is composed of a front clamp 100 , a rear clamp 300 , a flexible display screen 200 and a cylindrical lens grating 400 .

[0024] For further information, please refer to Figure 1 The front clamp 100 and the rear clamp 300 are made of a transparent material, specifically, they are made of a PET resin material. The front clamp 100 and the rear clamp 300 both have a periodic curved surface structure in the vertical direction, and the periodic curved surface structures can be interlocked with each other.

[0025] For further information, please refer to Figure 1 The flexible display screen 200 is placed between the front clamp 100 and the rear clamp 300 . After the front clamp 100 and the rear clamp 300 are engaged with each other, the flexible display screen 200 has the same periodic curved surface structure as the front clamp 100 and the rear clamp 300 .

[0026] For further information, please refer to Figure 2 The flexible display screen 200 is used to provide a parallax composite image, and the texture units 210 from different parallax images are arranged alternately in columns in the horizontal direction. Figure 3 , the texture unit 210 in each column of the flexible display screen 200 is composed of three pixels 201 arranged in the horizontal direction.

[0027] For further information, please refer to Figure 2 The cylindrical lens grating 400 is placed in front of the flexible display screen 200, and can project the texture units 210 of different parallax images to four different viewpoints. When the human eyes are at different viewpoints, they can see the corresponding parallax images, thereby generating stereoscopic vision.

[0028] For further information, please refer to Figure 4 , because the flexible display screen 200 has a periodic curved surface structure in the vertical direction, there are four texture units 211-214 with different vertical heights in one period. The distances of these four texture units 211-214 to the cylindrical lens grating 400 are different and are less than the focal length, so they can form an upright and enlarged virtual image. According to the lens imaging formula, these texture units 211-214 with different object distances should be imaged through the cylindrical lens grating 400, and the images 511-514 of the four texture units should have different image distances, so the texture units 211-214 with different vertical heights in the period can be used to represent image information of four different depths.

[0029] In summary, when a viewer views a parallax image, because the texture units 211 - 214 at different heights within a period on the flexible display screen 200 have different image distances, the present invention can provide image display at four different depths, thereby reducing visual fatigue.
