Embodiment Construction

[0048] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0049] figure 1 Schematic diagram of the parameter design method for integrated imaging high-density small-pitch LED display. (1) is a high-density small-pitch LED display, (2) is a lens array, and (3) is a lens element.

[0050] figure 2 Design a schematic for the lens element template. (3) is the lens element, (4) is the base.

[0051] Suppose the shape of the lens element (3) in the lens array (2) is circular, the array is arranged, and the aperture is P 2 , the focal length is f, and the refractive index is n, then the curvature radius r and the spherical height h are respectively:

[0052] r=f(n-1) \*MERGEFORMAT(1)

[0053]

[0054] Assuming that the pixel size of the high-density small-pitch LED display screen (1) is φ, the number of pixels contained in the lens element (3) is:

Abstract

The invention discloses an integral-imaging high-density small-interval LED display parameter design method, which belongs to the technical field of stereoscopic video display. Parameter matching is carried out on a lens array and a super high-density small-interval LED display screen, and according to the display parameters, a needed true three-dimensional video source (a stereoscopic element image array) is generated. The lens array is plano-convex lenses with an inscribed circle-shaped aperture. The stereoscopic element image array is acquired by adopting two modes of live-action shooting and virtual generation. Naked eye 3D stereoscopic display can be realized, the stereoscopic display effects are outstanding, and the color is bright.

Description

technical field [0001] The invention belongs to the technical field of stereoscopic video display, and in particular relates to an LED-based integrated imaging parameter design method. Background technique [0002] Completely reproducing the scene of the real natural space has always been one of the goals that human beings hope to achieve. In order to achieve this goal, generations of scientists have made arduous efforts. Samsung, LG, Sony, Sharp, Philips and other multinational companies have invested heavily in 3D research. Research on display technology, but current products can only achieve three-dimensional effects through human visual illusions. Since such products lose the phase information carried by light waves, it is impossible to realize true three-dimensional display. True 3D display is a brand-new 3D image display technology. This technology reconstructs the stereoscopic optical model of the original scene through the superposition of light, and restores the re...
