The invention provides a naked eye 3D system, which comprises a liquid crystal display panel, a first TN liquid crystal layer, a first wave plate, a first polarization grating plate, a second wave plate, a second TN liquid crystal layer, a third wave plate, a second polarization grating plate and a controller, wherein the liquid crystal display panel, the first TN liquid crystal layer, the first wave plate, the first polarization grating plate, the second wave plate, the second TN liquid crystal layer, the third wave plate and the second polarization grating plate are parallel to one another and are laminated in sequence; and the controller is electrically connected with the first TN liquid crystal layer, the second TN liquid crystal layer, the first polarization grating plate and the second polarization grating plate. The naked eye 3D system has the characteristics of being high in resolution ratio, small in system thickness and easy to integrate, has a 2D / 3D conversion function, the structure of an original liquid crystal display screen is not affected and the naked eye 3D system has great advantage and application prospect when applied to a portable display.
Description
technical field [0001] The invention belongs to the technical field of 3D display, in particular to a naked-eye 3D system. Background technique [0002] Glasses-free 3D display technology is an emerging high-tech display technology. This technology has attracted the attention of many people because of its shocking three-dimensional visual experience and strong sense of content, and because users can watch 3D effects without wearing any auxiliary equipment. This technology is mainly based on the principle of using the left and right eyes to obtain two different images with parallax to produce a three-dimensional visual effect. Most of the naked-eye 3D technologies developed at present are based on the principle of space division multiplexing of pixels on the LCD panel. The blocking principle of the slit grating to the light emitted by the pixels or the refraction principle of the lenticular lens array to the light allow the viewer to experience the 3D visual effect. But no...
