Abstract
A near-eye display device is provided. The near-eye display device includes a display screen, a light guide module and a defocus lens. The defocus lens receiving image light from the light guide module, has a first surface with a central region and a peripheral region. Integrated within the defocus lens are multiple microlenses, each convex towards the display screen. The near-eye display device allows the central region to focus a portion of the image light onto the user’s retina, creating a clear, sharp image. The microlenses focus a second portion of the image light in front of the retina.
Claims20
A near-eye display device, comprising:
- a display screen configured to emit an image light;
- a light guide module optically coupled to the display screen and configured to guide the image light;
- a defocus lens positioned to receive the image light from the light guide module and comprising a first defocus surface facing the light guide module and a second defocus surface opposite the first defocus surface;
- wherein the first defocus surface comprises a central region and a peripheral region surrounding the central region, the defocus lens further comprises a plurality of microlenses, and each of the plurality of microlenses is convex towards the display screen;
- the central region of the first defocus surface is configured to focus a first portion of the image light onto a retina of an eye of a user, and the plurality of microlenses is configured to focus a second portion of the image light in front of the retina of the eye of the user.
The near-eye display device of claim 4 wherein each of the first surface and the second surface is a convex surface.
A near-eye display device, comprising:
- a display screen configured to emit an image light;
- a light guide module optically coupled to the display screen and configured to guide the image light;
- a defocus lens positioned to receive the image light from the light guide module and comprising a first defocus surface facing the light guide module and a second defocus surface opposite the first defocus surface;
- each of the first defocus surface and the second defocus surface being an aspheric surface;
- wherein the first defocus surface comprises a central region and a peripheral region surrounding the central region;
- the defocus lens further comprises a plurality of microlenses, each of the plurality of microlenses is convex towards the display screen;
- the central region of the first defocus surface is configured to focus a first portion of the image light at a first focal plane, the plurality of microlenses is configured to focus a second portion of the image light at a second focal plane, and the second focal plane is positioned between the defocus lens and the first focal plane.
