Embodiment 1

[0073] When human eyes observe the real world, refer to figure 2 As shown, the focal depth of the monocular is at the same position as the converging depth of the binocular, and there will be no dizziness. And when users watch the 3D display device based on parallax, refer to figure 1 As shown, the focus depth of one eye is inconsistent with the convergence depth of both eyes, which will cause visual fatigue and cause users to experience dizziness and other adverse experiences.

[0074] In order to solve this problem, an embodiment of the present invention provides a light field display device. refer to Figure 13 As shown, the light field display device includes: a display screen 1 and a lens unit 2 arranged on the light emitting side of the display screen 1 . which, combined with Figure 14 and Figure 15 , the lens unit 2 includes a plurality of lenses 3 arranged in an array; the display screen is arranged on the focal plane of the plurality of lenses.

Abstract

The invention provides a light field display device, relates to the technical field of display, and aims to solve the problem of visual fatigue caused by inconsistent monocular focusing depth and binocular convergence depth and prevent a user from feeling dizzy. The light field display device comprises a display screen and a lens unit arranged on the light emitting side of the display screen, wherein the lens unit comprises a plurality of lenses arranged in an array; the display screen is arranged on the focal planes of the plurality of lenses; the display screen comprises a first substrate and a second substrate which are oppositely combined, wherein the first substrate is a light emitting side substrate, the second substrate comprises a plurality of pixel islands arranged in an array, and each pixel island comprises at least one sub-pixel; the plurality of pixel islands correspond to the plurality of lenses; light rays emitted by sub-pixels of the pixel island are transmitted to a view area formed by human eyes through the corresponding lenses to be smaller than or equal to a half pupil area, and light rays, emitted by different sub-pixels in the pixel island, of different viewpoints are emitted into different view cone cells through the lenses. The invention is suitable for manufacturing the light field display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a light field display device. Background technique [0002] When human eyes observe the real world, they rely on binocular parallax to produce stereoscopic vision. Based on this principle, researchers have developed a parallax-based 3D display device, such as a VR (Virtual Reality, virtual reality) display device. refer to figure 1 As shown, when the user watches the 3D display device based on parallax, the monocular focus is on the display screen, but the stereoscopic images actually seen by the user are located on planes with different depths; that is, the focal depth of the monocular is inconsistent with the converging depth of the binoculars, which will cause visual Fatigue, which in turn causes users to experience dizziness and other adverse experiences.
