Problems solved by technology

Lenticular lens technology will not block the backlight, and the brightness of the display will not be affected, but because it also projects different pixels to the left and right eyes separately, which is the same as the parallax barrier technology, so the resolution will still be reduced during 3D display. rate will be doubled

Embodiment Construction

[0014] Such as figure 1 shown. The outgoing light of the high-frequency image source 1 passes through the light splitting element 2 and the lens group 3 in sequence, and enters the light valve curtain 4 and is received by the left eye of the human body. After passing through the light valve curtain 4, it enters the liquid crystal light valve and reflector with polarizer After combination 5, it is received by the right eye of the human body.

[0015] This naked-eye stereoscopic display spectroscopic system must realize comb-like distribution of image sources in space to avoid crosstalk between left and right eyes. This is because the system uses a time-sharing method to display images for the left and right eyes, instead of arranging the pixels of the left and right eyes at odd and even intervals (because the arrangement of odd and even intervals will reduce the resolution). If there is no space splitting, the image seen by the left eye It will be a continuous area, and the i...

Abstract

The invention discloses a light splitting system for naked eye three-dimensional display. A high-frequency image source is adopted, a one-grade grating and a two-grade grating are sequentially arranged in front of a light path of the high-frequency image source, wherein the one-grade grating is a diffraction grating, the two-grade grating is a black-white grating, and finally a plurality of sub image sources distributed in a comb-shaped manner are formed in a space. The light splitting system provided by the invention has better light splitting effect, and is used for modulating emergent light of the high-frequency image source sequentially through the one-grade diffraction grating and the two-grate black and white grating, thus crosstalk in the optical error-based three-dimensional display can be greatly reduced.

Description

technical field [0001] The invention relates to the field of naked-eye stereoscopic display optical systems, in particular to a spectroscopic system for naked-eye stereoscopic display. Background technique [0002] In the prior art, there are two parallax-type glasses-free three-dimensional display methods: parallax barrier (front and rear) and lenticular methods. The parallax barrier stereoscopic display technology uses a series of light-shielding stripes arranged in the vertical direction between the backlight module and the LCD panel to form a parallax barrier, which separates the images of the left eye and the right eye, so that 3D images can be obtained, and some programs install the parallax barrier in the LCD front. At present, the parallax barrier is generally realized by liquid crystal, so that by controlling the switch of the parallax barrier, 2D images are displayed when there is no parallax barrier, and 3D images are displayed when there is a parallax barrier. ...
