Abstract

The invention provides an energy-saving jump-image-free integral imaging and displaying device based on grating waveguide, which is used to solve the technical problem that existing integral imaging and displaying devices have low light energy utilization rate and cannot balance the imaging quality and the processing technology. The energy-saving jump-image-free integral imaging and displaying device based on grating waveguide comprises an LED light source, a waveguide medium, a display panel and a microlens array. The LED light source is an array light source formed by red, green and blue three-primary-color LED lights. The display panel is a liquid crystal panel without a color filter. A grating which consists of a plurality of periodically-arranged grating elements is disposed on the surface, adjacent to the display panel, of the waveguide medium. Each grating element comprises three grating regions corresponding to the periods of red, green and blue three-primary-color light, from large to small. The microlens array, the display panel and the waveguide medium are sequentially arranged in parallel. The LED light source is located at the side of the waveguide medium. Light emitted from the LED light source is irradiated onto the corresponding grating region, and light emitted from the region can be vertically irradiated only onto a light channel, corresponding to the region, on the display panel.

Description

technical field [0001] The invention belongs to the technical field of integrated imaging three-dimensional display, in particular to integrated imaging three-dimensional display, in particular to an energy-saving and jump-free image integrated imaging display device based on a grating waveguide, which is used to reproduce three-dimensional information in object space. Background technique [0002] The integrated imaging 3D display technology includes two stages of recording and display. The recording stage is to use the microlens array to record the three-dimensional object space information and obtain the microimage array; the display stage is to use the microlens array with the same parameters as the microlens array used in the recording stage to The light emitted by the micro-image array is converged and restored to reconstruct the three-dimensional light field information in the object space. The concept of integrated imaging three-dimensional display technology was fir...
