Head Mount Display with Near-Eye Projection for Virtual Reality System
A system that provides a head mount display (HMD) unit that provides visual content, such as video, through a projection system incorporated within the head mount display unit. The projection system is positioned near a user's eye within the HMD and provides a visual experience that is higher resolution, has a higher refresh rate, runs cooler, requires less power, and provides a broader field of view than typical HMD units, such as an HMD which utilizes a curved display screen.
1 . A system for projecting a beam within a head mount display worn by a user, including:
a light source within the head mount display that provides light to a digital imaging circuitry;
digital imaging circuitry within the head mount display that receives the light and a digital signal and projects image data as a beam;
projection optics that project the beam; and
a mirror having a curve that reflects the projected beam to a user.
2 . The system of claims 1 , wherein the focal length of the mirror is less than 80 millimeters.
3 . The system of claims 1 , wherein the system includes a second projector, a second beam splitter, a second filter and a second mirror for projecting split, filtered beams to a second pupil of the user.
4 . The system of claim 1 , wherein the digital imaging circuitry or projection optics are movable to adjust a focal plane for the beam.
