Photoelectric dual-modulation three-dimensional display method, display element and three-dimensional display device

Abstract

The invention discloses a photoelectric dual-modulation three-dimensional display method, a display element and a three-dimensional display device.The three-dimensional display method based on electric field and light field dual-modulation is used for three-dimensional display of the display element, the display element is provided with a plurality of display layers, and the three-dimensional display method comprises the steps of extracting at least shape information of a three-dimensional image needing to be displayed; generating a scanning scheme for each display layer of the display element according to the shape information; and extracting color information of the three-dimensional image needing to be displayed. Therefore, scanning and generation of the target pattern on the display element are facilitated, and independent control of display of each display layer is realized by independently applying a reverse voltage or not applying a voltage to each display layer, so that layer-by-layer addressing scanning is facilitated, and furthermore, the electric field modulation speed is high, the display element has the advantages of being easy to manufacture, large in size, high in resolution depth and the like, and the problems that other displays are small in display format, low in refresh frequency, low in brightness, small in viewing angle range and the like are solved.

Description

technical field [0001] The invention relates to the field of three-dimensional display, in particular to a photoelectric double modulation three-dimensional display method, a display element and a three-dimensional display device. Background technique [0002] In related technologies, 3D display is generally divided into true holographic 3D display and volumetric 3D display. True holographic 3D display has a smaller frame size and a lower refresh frame rate during use. [0003] Volumetric 3D display is divided into rotary scanning type and solid volume type. The problem of rotary scanning type is that it has low brightness and is not suitable for applications requiring large screens. Solid-state volumetric methods such as 3D display based on up-conversion materials and 3D display technology based on liquid crystal stacking, the 3D display based on up-conversion materials also have the problems of low brightness and low image display contrast; the viewing angle of 3D display ...
