Embodiment Construction

[0061] Aiming at the problems existing in the prior art that eye fatigue and dizziness may be caused when a user wears a near-eye display device for a long time, an embodiment of the present invention provides a light field display device and a display method thereof.

[0062] The specific implementation manners of the light field display device and the display method thereof provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The thickness and shape of each film layer in the drawings do not reflect the real scale, and the purpose is only to illustrate the content of the present invention.

[0063] In the first aspect, the embodiment of the present invention provides a light field display device, such as image 3 As shown, it includes: a line-of-sight tracking element 11, an image rendering element 12, a display element 13, a focus adjustment element 14 located on one side of the light-emitting sur...

Abstract

The invention discloses a light field display device and a display method thereof. A system control element is used for making an image rendering element render a display image according to a set timesequence based on three-dimensional position information obtained by a sight tracking element so that a display image conforms to a visual effect of a human eye focusing plane, and is used for makinga focal length adjusting element adjust a focal length according to the set time sequence. Total duration of the set time sequence corresponding to each display period is less than refreshing time ofhuman eyes. A display element is used for emitting light carrying the image information of the rendered display image. The focal length adjusting element is used for emitting the light emitted by thedisplay element to a projection lens. The projection lens is used for projecting the light emitted by the focal length adjusting element to an optical element. And the optical element is used for emitting the light projected by the projection lens to the human eyes. Through focusing adjustment of a plurality of imaging surfaces within a certain depth range, a natural 3D image is presented, and eye fatigue and dizziness caused by long-term watching of the human eyes are avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light field display device and a display method thereof. Background technique [0002] In the current field of near-eye display, when a user wears a near-eye display device, the displayed three-dimensional (3D) object is a stereoscopic vision formed by displaying different images to the left and right eyes of the user respectively. Since the 3D display based on binocular stereovision There is a problem of vergence adjustment conflicts, such as figure 1 As shown, when the human eye looks at objects in the real world, the focus distance of the human eye is consistent with the convergence distance, as shown in figure 2 As shown, when the human eye watches the display screen, the focusing distance of the human eye is the distance between the human eye and the display screen, and the convergence distance of the human eye is the distance between the human eye and the virtual image...
