Problems solved by technology

However, the 2D display panel in the traditional stereoscopic display device cannot provide the depth information of the image content, therefore, the image finally displayed on the display device is located on the same plane as the display device, and the visual fidelity is limited.

Embodiment

[0025] figure 1 A schematic structural diagram of a stereoscopic display device 010 with π-type pixel arrangement provided in this embodiment. In the figure, the x coordinate represents the horizontal direction in space, the y coordinate represents the vertical direction in space, and z represents the direction perpendicular to the x-y plane. The stereoscopic display device 010 with π-type pixel arrangement is composed of a 2D display panel 100 and a lenticular grating structure 200 .

[0026] Please refer to figure 2 , the minimum periodic structure 110 on the 2D display panel is arranged with 3 pixels. The minimum three pixels contained in the minimum periodic structure 110 on the 2D display panel are the first pixel 111 , the second pixel 112 and the third pixel 113 respectively, and the arrangement of the above three pixels forms a "π" shape. Please refer to figure 2 , the horizontal height of the first pixel 111 is different from that of the remaining two pixels 112...

Abstract

The invention provides a three-dimensional display device in pi-shaped pixel arrangement. The three-dimensional display device is composed of a 2D display panel and a cylindrical lens grating. At least three pixels are contained in a minimum periodic structure on the 2D display panel and are arranged to form a pi shape, wherein the horizontal height of at least one pixel is different from that ofthe other pixels, and at least two pixels are located at different horizontal positions. Meanwhile, the distance from the cylindrical lens grating to the 2D display panel is less than the focal lengthof the cylindrical lens grating. Due to the arrangement, each minimum periodic structure in the three-dimensional display device can display the vertical texture of the image at the current positionof the 2D display panel, and can also display the horizontal texture of the image behind the 2D display panel, so multi-depth image information display can be provided, and the perception trueness ofthe three-dimensional image is enhanced.

Description

technical field [0001] The present invention relates to display technology, more specifically, the present invention relates to stereoscopic display technology. Background technique [0002] Stereoscopic display technology is a display technology that can realize the true reproduction of stereoscopic scenes, and it can provide different parallax images for human eyes, so that people can have stereoscopic vision. Traditional stereoscopic display devices can project parallax composite images to various positions in space through a 2D display panel, and viewers can see corresponding parallax images when they are in different positions to generate stereoscopic vision. However, the 2D display panel in the conventional stereoscopic display device cannot provide depth information of the image content. Therefore, the image finally displayed by the display device is located on the same plane as the display device, and the visual fidelity is limited. Therefore, the invention proposes...
