Problems solved by technology

[0012] The main purpose of the present invention is to provide a 3D display unit, a stereoscopic display device and a method for eliminating moiré, so that when elliptically polarized light passes through the existing 3D display unit, only by adjusting the grating of the binocular parallax splitting layer The angle between the extension direction of the pixel and the arrangement direction of the pixels in the 2D display module still cannot solve the problem of moiré

Embodiment 1

[0056] Such as figure 2 As shown, the 3D display unit includes a 2D display module layer 10 (elliptical polarization), a phase difference film 20 (wave plate), an adhesive layer 30 (UV glue) and a binocular parallax light splitting layer 40 (slits) stacked in sequence. grating structure). The elliptically polarized light of the 2D display module can be converted into linearly polarized light by the retardation film 20 (wave plate). Then, by adjusting the inclination angle of the binocular parallax light-splitting layer 40, the moiré phenomenon can be weakened and a good stereoscopic display effect can be obtained.

Embodiment 2

[0058] Such as image 3 As shown, the 3D display unit includes a 2D display module layer 10 (elliptical polarization), a phase difference film 20 (wave plate), an adhesive layer 30 (UV glue) and a binocular parallax light splitting layer 40 (liquid crystal narrowing) stacked in sequence. slit grating structure). The elliptically polarized light of the 2D display module can be converted into linearly polarized light through a retardation film 20 (wave plate) of a specific thickness. Then, by adjusting the inclination angle of the binocular parallax light-splitting layer 40, the moiré phenomenon can be weakened and a good stereoscopic display effect can be obtained.

Embodiment 3

[0060] Such as Figure 4 As shown, the 3D display unit includes a 2D display module layer 10 (ellipsoid), a phase difference film 20 (wave plate), an adhesive layer 30 (UV glue) and a binocular parallax light splitting layer 40 (rod prism) stacked in sequence. Grating) can convert the elliptically polarized light of the 2D display module into linearly polarized light through a phase difference film 20 (wave plate) of a specific thickness, and then adjust the inclination angle of the grating to improve the moire pattern and obtain a good display Effect.

Abstract

The invention provides a 3D display unit, a stereoscopic display device and a method for eliminating moire. The 3D display unit comprises a 2D display module layer, a binocular parallax light-splitting layer and a phase difference film, wherein the 2D display module layer is used for displaying a 2D view which can output elliptically polarized light; the binocular parallax light-splitting layer isarranged on the surface of one side of the 2D display module layer, and is used for splitting the 2D view; the phase difference film is arranged between the binocular parallax light-splitting layer and the 2D display module layer, and is used for converting the elliptically polarized light into linearly polarized light. According to the technical scheme adopted by the invention, through arrangement of the phase difference film between the 2D display module layer and the binocular parallax light-splitting layer, the elliptically polarized light output from the 2D display module layer can be converted into the linearly polarized light, and through adjustment of an included angle between the extension direction of a grating of the binocular parallax light-splitting layer and the arrangementdirection of pixels of the 2D display module layer, a moire phenomenon in a displayed picture can be improved.

Description

technical field [0001] The invention relates to the field of 3D display, in particular to a 3D display unit, a stereoscopic display device and a method for eliminating moiré. Background technique [0002] Glasses-free 3D is a new type of stereoscopic display technology, which allows viewers to enjoy good stereoscopic display effects without wearing any auxiliary vision glasses or helmets. The grating display has the characteristics of simple structure, low cost, and good performance. And received much attention. According to the grating used, it can be divided into slit grating 3D display and cylindrical lens grating 3D display. [0003] The 3D display of the slit grating is to place a slit with qualified parameters in front of the display panel. The light-transmitting strips and the light-blocking strips of the slit grating are arranged alternately. The effect of light, combined with the left and right time differences arranged correspondingly on the 2D display screen, re...
