Embodiment

[0027] figure 1 A schematic structural diagram of a stereoscopic display device 010 based on a pixel mask 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.

[0028] The stereoscopic display device 010 based on a pixel mask is composed of a 2D display panel 100, a pixel mask 200, and a lenticular lens grating 300. The pixel mask 200 is placed close to the front of the 2D display panel 100, and the lenticular lens grating 300 is placed on the pixel mask. Before 200. The 2D display panel 100 is used to provide a parallax composite image. In the parallax composite image, pixels in different rows belong to different parallax images. The pixel mask 200 is provided with light holes, and the light from the pixels on the 2D display panel 100 can exit through the light holes on the pixel mask 200 , and be p...

Abstract

The invention provides a stereoscopic display device based on a pixel mask. The stereoscopic display device based on the pixel mask is composed of a 2D display panel, the pixel mask and a cylindricallens grating, wherein the pixel mask is closely placed in front of the 2D display panel, and the cylindrical lens grating is placed in front of the pixel mask; the 2D display panel is used for providing a parallax composite image, and in the parallax composite image, pixels in different rows belong to different parallax images; the pixel mask is provided with light holes, and light of the pixels on the 2D display panel can be emitted through the light holes in the pixel mask and projected to all viewpoint positions through the cylindrical lens grating; when human eyes are located at differentviewpoint positions, parallax images corresponding to the human eyes can be seen, and thus stereoscopic vision is generated; and the light holes have different horizontal pitches, so that a pluralityof optimal viewing distances can be realized.

Description

technical field [0001] The present invention relates to display technology, and more specifically, the present invention relates to stereoscopic display technology in display. Background technique [0002] The stereoscopic display device can provide parallax images in different spatial directions, so that the viewer can have stereoscopic vision. However, in the conventional stereoscopic display device, the positions of the viewpoints are only distributed in the optimal viewing distance due to the limitation of the pixel pitch. Correct parallax images can only be seen when the viewer is at an optimal viewing distance. Therefore, the present invention proposes a stereoscopic display device based on a pixel mask, which can provide various pixel pitches through the pixel mask, so it can provide multiple optimal viewing distances. Contents of the invention [0003] The invention proposes a stereoscopic display device based on a pixel mask. attached figure 1 It is a structur...
