Lenticular grating based LED stereoscopic display screen device with great many of viewpoints

Abstract

The invention provides a lenticular grating based LED stereoscopic display screen device with a great many of viewpoints. The display screen device comprises an LED planar display screen and human-eye watching viewpoints, an arc lenticular grating is arranged between the LED planar display screen and human-eye watching viewpoints, the LED planar display screen is arranged along the axis x and symmetric by taking the axis x as the center, the vertex of a cylindrical lens of the intermediate arc lenticular grating is positioned in the coordinate origin, an image side of the LED planar display screen is positioned in the focal plane of the cylindrical lens of the arc lenticular grating, the width of sub-pixel is t, the lenticular thickens of the arc lenticular grating is d, distance between the cylindrical lens of the arc lenticular grating and the LED planar display screen is s, the human-eye watching viewpoints are positioned in positions whose distance to the cylindrical lens of the arc lenticular grating is L, and the distance between the eyes is set as e. A 3D structure with a static effect as well as a 3D image with a dynamic effect can be realized.

Description

technical field [0001] The invention relates to the field of three-dimensional space display, in particular to a super multi-viewpoint LED three-dimensional display device based on a lenticular lens grating. Background technique [0002] At present, when displaying in a three-dimensional space, a three-dimensional display device is generally used to display a three-dimensional space, and most of the current three-dimensional space display devices usually require the aid of auxiliary equipment to achieve three-dimensional display, but the use of auxiliary equipment for display operations It is complex and costly, and cannot be used in special environments. The current naked-eye 3D display technology is also known for its high cost, and traditional 3D display devices have few visible points, small viewing range, and strong crosstalk between viewpoints. The imaging effect is poor, and free stereoscopic viewing effects cannot be obtained. Therefore, it is particularly important...
