Abstract

The invention relates to the technical field of display, and provides a display system and a display method. The display system comprises an optical waveguide and a squeezed light field module. The optical waveguide is provided with a first surface and a second surface parallel with the first surface. The first surface comprises a light incidence region and a light outgoing region. Light entering the light incidence region spreads in the optical waveguide, and then emits from the light outgoing region. The squeezed light field module is used to synthetize a squeezed light field including a displayed image, and emits the squeezed light field to the light incidence region. Through the squeezed light field module, the light field is projected and coupled into the optical waveguide, and the light field is coupled out of the optical waveguide, and the light can be seen by human eyes, to realize a near-to-eye display mode and light field display. The system and the method prevent focusing contradiction, light is natural and comfortable and has no spinning sensation, and the system solves problems of dizziness and visual fatigue caused by looking at a stereoscopic vision 3D image formed by two parallactic two-dimensional images by human eyes for long time.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display system and a display method. Background technique [0002] Now in the field of display, when a user wears or watches a 3D display device, the displayed 3D object is formed by displaying different images to the left and right eyes of the user to form a stereoscopic vision. Due to the 3D display based on binocular stereoscopic vision, there is a convergence adjustment conflict. The problem is that when users wear it for a long time, it will cause eye fatigue and dizziness. This is an urgent problem to be solved in stereoscopic display. For details, please refer to Figure 1-2 (1, 2 and 3 in the figure represent the left eye, right eye and display screen respectively, L and L' represent the convergence distance and focus distance respectively), where figure 1 A schematic diagram showing the situation in which the human eye observes the real world, figure ...
