Problems solved by technology

However, the existing waveguide displays use conventional projection. In order to correct the phase difference and chromatic aberration, the structure of the waveguide is relatively complicated and difficult to manufacture.
In addition, the huge size and complex lens system of conventional projectors also limit their application in waveguide displays.

Embodiment Construction

[0062] like figure 1 , 2 As shown, the holographic waveguide display of the embodiment of the present invention includes a waveguide 11 as a display screen and a holographic projection system 12 for inputting holographic images to the waveguide. The shape of the waveguide can be as figure 1 As shown, the initial shape of the side is triangular, and its front end vertex angle is α. In order to save material, the useless part of the front end can be cut off to make it wedge-shaped. The plane of angle β. Its top view can be a rectangle, a triangle, or other shapes that are convenient for display. The second half is used as an image diffusion area 111 (light propagation area), and the front half is used as a display area 112 for displaying images. The rear half can also be folded to the back of the front half to save space (such as image 3 , Figure 4 )), so that the shape of the waveguide display is the same as that of an ordinary flat-panel display. There is an interface ...

Abstract

The invention belongs to an image display device and a method, relating to a holographical wave guide display taking a planar wave guide as a display screen and a generation method of a holographical image adaptive to the holographical wave guide display. The holographical wave guide display comprises a wave guide serving as the display screen and a holographcal projection system used for inputting the holographical image to the wave guide; the wave guide is provided with a light input panel and a light output panel; the incident light ray can be transmitted in the wave guide until leaving the wave guide from the light output panel; and the emergent position of the light ray on the light output panel is mutually determined by the position of point of incidence and the incidence angle of the light ray on the incidence panel. The holographical wave guide display of the invention can display the holographical image, can adopt the wave guide as a display carrier to manufacture the display which has jumbotron, low cost and environment protection and is energy-saving, sturdy and durable.

Description

technical field [0001] The invention belongs to an image display device and method, and relates to a holographic waveguide display using a plane waveguide as a display screen and a method for generating holographic images adapted to the holographic waveguide display. Background technique [0002] Holographic display technology is a technology that converts an image into its diffraction pattern at a certain distance, and uses one or more monochromatic light sources to illuminate the diffraction pattern. After a certain distance of propagation, due to light diffraction and interference effects, the diffraction pattern can be restored to the original target image. Compared with ordinary projection and liquid crystal display technology, holographic projection has the following advantages: [0003] 1. Energy saving: Unlike liquid crystal displays that block unwanted light, holographic displays modulate and guide light, theoretically all incident light energy will be effectively ...
