Technical Field

The present invention relates to display technology, and more particularly, to stereoscopic display technology.

Background

The stereoscopic display technology is a display technology that can realize real reproduction of a stereoscopic scene, and can provide different parallax images to human eyes, respectively, thereby enabling a person to generate stereoscopic vision. The invention provides a multi-visual-area stereoscopic display device.

Disclosure of Invention

The invention provides a multi-visual-area stereoscopic display device. Fig. 1 is a schematic structural diagram of the multi-view stereoscopic display device, wherein x denotes a horizontal direction in space, y denotes a vertical direction in space, and z denotes an axial direction perpendicular to an xy plane. The multi-view-area stereoscopic display device consists of a 2D display panel and a slit grating. The 2D display panel is placed behind the slit grating. The slit grating may project pixels on the 2D display panel to various spatial locations.

Further, referring to fig. 2, the pixels on the 2D display panel have various shapes, and the pixels with the same shape belong to the same viewing area.

Further, referring to fig. 3, the slit grating is provided with slits having a plurality of opening shapes, and the opening shape of each slit corresponds to the pixel shape of each viewing area, so as to project the pixels respectively.

Further, referring to fig. 1, pixels belonging to the same viewing area and having the same shape can be projected to the corresponding viewing area position through the slit corresponding to the shape.

Furthermore, on the 2D display panel, pixels with the same shape are periodically arranged in columns, each column of pixels in the period is from a different parallax image, different columns of pixels can be projected to different viewpoint positions in the visual area, and when human eyes are located at different visual area positions in the visual area, the corresponding parallax images can be seen, so that stereoscopic vision is generated.

Further, referring to fig. 4, the light transmittance between the slits and the pixels of different shapes is low, which makes the projection difficult. Therefore, referring to fig. 1, in any view area, except the pixels corresponding to the view area, the other pixels have different shapes from the slit opening, so that the light transmittance is low, and the projection is difficult, and the crosstalk is less; at the position between the visual areas, no pixel matched with the shape of any slit is arranged, so that the light transmittance is low, and no obvious image is displayed.

Further, the light projection of the pixels with different shapes is independent. Specifically, when the position of a slit having a certain opening shape is changed, only the projection direction of the pixel corresponding to the opening shape is changed, and the projection direction of the pixels having other shapes is not affected.

Optionally, the shape of the pixel on the 2D display panel may be formed by combining a plurality of pixels, and the opening on the slit grating matches the shape formed by combining a plurality of pixels.

In summary, the present invention can form a plurality of viewing zones in space, and the positions of the viewing zones are independent from each other, when the position of one viewing zone changes, the positions of other viewing zones can not be affected, and no image is displayed between the viewing zones.
