Problems solved by technology

The current retinal projection technology uses laser as the projection light source. The high-energy laser converges to the pupil of the human eye, which is not suitable for long-term viewing, and requires red, green, and blue lasers to be projected separately, which increases the complexity of the system.

Abstract

The invention discloses a retinal imaging three-dimensional display device, which comprises a left-eye retinal imaging subsystem and a right-eye retinal imaging subsystem. The left-eye retinal imagingsubsystem and the right-eye retinal imaging subsystem have the same components, and each comprise a point light source, a lens, a transmissive display panel and a transflective mirror. The componentsin the left-eye retinal imaging subsystem and the right-eye retinal imaging subsystem are symmetrically distributed about the central axis of both eyes. A spherical wave emitted by the lens convergesat the point light source, forms convergence points at the left and right eye pupils of a viewer, and forms images on the retinas to realize the retinal imaging three-dimensional display.

Description

technical field [0001] The invention relates to retinal imaging and three-dimensional display technology, in particular to a retinal imaging three-dimensional display device. Background technique [0002] Retinal projection or retinal imaging is an emerging near-eye display technology in recent years. The image is directly projected onto the retina of the human eye through a micro-projection system, without the need for the focusing function of the human eye, so that both myopia and hyperopia patients can see clear images. Projected images, and as the viewer's focus distance changes, the projected images still maintain a clear effect. The current retinal projection technology uses laser as the projection light source. The high-energy laser converges to the pupil of the human eye, which is not suitable for long-term viewing, and requires red, green, and blue lasers to be projected separately, which increases the complexity of the system. Contents of the invention [0003] ...
