Embodiment

[0065] A display system such as figure 2 As shown, including the display, OLED screen is used, and the resolution is 1920x1080. The spatial light modulator is a reflective phase modulation silicon-based liquid crystal device, which adopts ECB mode liquid crystal package. The pixel size is 4.6um, the shape is square, and the resolution is 3840x2160. The control circuit uses the solution of CPU+ASIC. The system also includes a polarizer, which is arranged between the OLED and the spatial light modulator, and is used for modulating the polarization direction of the image light emitted by the OLED to be consistent with the direction required by the spatial light modulator. A grating waveguide is also included in the system to expand the image output by the spatial light modulator (pupil expansion).

[0066] The role of each part is as follows:

[0067] The OLED screen generates an image, and the image adopts a time-division multiplexing method, that is, the control circuit cont...

Abstract

The invention provides a display system and a binocular system, comprising: a display, a spatial light modulator and a control circuit, the light output by the display obliquely enters the spatial light modulator, and the light is modulated by the spatial light modulator Output, the control circuit is respectively connected to the display and the spatial light modulator, controls the image displayed by the display, and controls the modulation signal of the spatial light modulator; the display corresponds to the spatial light modulator Different parts of , respectively, show different focal lengths. The invention has a simple structure, and the display is corresponding to different parts of the spatial light modulator, so as to display different focal lengths respectively and realize 3D visual effects.

Description

technical field [0001] The invention relates to the field of optical display devices, in particular to a display system and a binocular system. Background technique [0002] The invention patent with the publication number CN105700320A discloses a holographic three-dimensional display method and device based on a spatial light modulator. The directional diffraction screen constitutes. Obtain the multi-view two-dimensional image of the target object, and generate a set of image arrays for phase hologram calculation after the preprocessing transformation process. The iterative Fourier transform algorithm is used to calculate the corresponding phase hologram, and the hologram is loaded into the spatial light modulator, and the hologram is illuminated by a laser light source to obtain a holographic reconstruction image. Design and manufacture a directional diffraction screen based on a pixel-type nano-grating, and directional diffract the corresponding reproduced image pixels ...
