Problems solved by technology

However, there are two obvious deficiencies in the existing dual-view display: 1. It can only display two different 2D images in the left and right directions at the same time, which cannot meet the needs of the viewer located in the middle of the display screen; 2. The screen is a 2D screen, and 3D display cannot be realized

Abstract

The invention relates to the 3D display technology, specifically relates to microlens array based integral imaging three-view 3D display device and method, and aims at achieving the three-view 3D display. The device comprises a 2D display screen and a microlens array; the microlens array comprises a plurality of lens elements with the same parameters; the 2D display screen is used for micro-image arrays which include a first secondary micro-image array, a second secondary micro-image array and a third secondary micro-image array; each micro-image array comprises a plurality of secondary image elements which are arranged in parallel; each image element comprises three secondary image elements which are arranged in parallel; the horizontal width of single image element is more than that of single lens element; the secondary image elements of the three secondary micro-image arrays respectively pass through the corresponding lens elements to be toward the right, middle and left of an integral imaging display device so as to reconstruct a 3D scene, and as a result, the three-view 3D display can be achieved. The device and method can be widely applied to the fields of advertisement display and other three-view 3D imaging.

Description

technical field [0001] The invention relates to 3D display technology, in particular to the field of integrated 3D display. Background technique [0002] Dual-vision display is a new type of display that has appeared in recent years. It can display two different pictures on one display screen at the same time. Meet the different needs of multiple viewers at the same time. Existing dual-vision displays use parallax barriers or cylindrical lenses to separate the two images, or allow the viewer to wear different filter devices to achieve the effect that only one image can be viewed in a certain viewing direction. However, there are two obvious deficiencies in the existing dual-view display: 1. It can only display two different 2D images in the left and right directions at the same time, which cannot meet the needs of the viewer located in the middle of the display screen; 2. The screen is a 2D screen and cannot be displayed in 3D. [0003] The integrated imaging 3D display i...
