Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention is not limited to the following embodiments.

[0028] The lenticular lens grating 3D TV viewing system provided by this embodiment at least includes a display, a lenticular lenticular grating, and a seat. The three are located on the same straight line. The plane is located on the focal plane of the cylindrical lens grating, and the light emitted from each point on the display plane can be transformed into a parallel beam after being refracted by the cylindrical lens; the distance between the seat and the cylindrical lens grating is D 1 ~D 2 , this distance is the best viewing distance, where D 1 is the shortest vertical distance, D. 2 is the longest vertical distance,

[0029] The method for determining the optimal viewing distance will be described in detail below in conjunction with the accompa...

Abstract

The invention provides a cylindrical lens grating 3D television watching system, and particularly relates to a 3D television watching system with a seat at the optimum watching distance away from a television. The system at least comprises a displayer, a cylindrical lens grating and the seat. The displayer, the cylindrical lens grating and the seat are located on the same straight line. The cylindrical lens grating is located between the displayer and the seat. The display plane of the displayer is located on the focal plane of the cylindrical lens grating. Light emitted by all points on the display plane is reflected by a cylindrical lens and then is converted into parallel light beams. The distance between the seat and the cylindrical lens grating ranges from D1 to D2 and is the optimum watching distance, wherein D1 is the shortest perpendicular distance, and D2 is the longest perpendicular distance. A watcher can obtain the better 3D display effect and the comfortable visual perception at the optimum watching distance away from the television.

Description

technical field [0001] The invention provides a cylindrical lens grating 3D TV viewing system, in particular relates to a 3D TV viewing system in which a seat is in an optimal viewing distance, and belongs to the technical field of 3D TV. Background technique [0002] Glasses-free 3D technology can be divided into grating, volumetric and holographic 3D technologies. [0003] The grating-type multi-view autostereoscopic display has become one of the mainstream stereoscopic displays due to its simple structure, easy implementation, and good stereoscopic display effect. Its main structure is to add a slit grating or a cylindrical lens grating to the flat panel display. [0004] Multiple parallax images are synthesized into a three-dimensional image with sub-pixels as a unit according to certain rules and displayed on a flat-panel display. The light from different parallax images propagates in different directions by using the spectroscopic effect of the grating. When the viewe...
