DIRECT VIEW AUGMENTED REALITY EYEGLASS-TYPE DISPLAY
First Claim
1. A transparent light-field projector (LFP) device for providing an augmented reality display, the device comprising:
- a transparent solid-state LED array (SLEA) comprising a plurality of integrated light-emitting diodes (iLEDs);
a micro-array (MA) placed at a separation distance from the SLEA, the MA comprising a plurality of either microlenses or micro-mirrors; and
a processor communicatively coupled to the SLEA and adapted to;
identify a target pixel for rendering on the retina of a human eye,determine at least one iLED from among the plurality of iLEDs for displaying the pixel,move the at least one iLED to a best-fit pixel location relative to the MA and corresponding to the target pixel, andcause the iLED to emit a primary beam of a specific intensity for a specific duration.

Abstract
A low-power, high-resolution, see-through (i.e., “transparent”) augmented reality (AR) display without projectors with relay optics separate from the display surface but instead feature a small size, low power consumption, and/or high quality images (high contrast ratio). The AR display comprises sparse integrated light-emitting diode (iLED) array configurations, transparent drive solutions, and polarizing optics or time multiplexed lenses to combine virtual iLED projection images with a user'"'"'s real world view. The AR display may also feature full eye-tracking support in order to selectively utilize only the portions of the display(s) that will produce only projection light that will enter the user'"'"'s eye(s) (based on the position of the user'"'"'s eyes at any given moment of time) in order to achieve power conservation.

13. A method for multiplexing a plurality of integrated light-emitting diodes (iLEDs) in a light-field projector (LFP) comprising a transparent solid-state LED array (SLEA) having a plurality of iLEDs and a micro-array (MA) having a plurality of either microlenses or micro-mirrors placed at a separation distance from the SLEA, the method comprising:
-
arranging a plurality of iLEDs to achieve overlapping orbits; identifying a best-fit pixel for each target pixel; orbiting the iLEDs; and emitting a primary beam to at least partially render a pixel on a retina of an eye of a user when an LED is located at a best-fit pixel location for a target pixel that is to be rendered. - View Dependent Claims (14, 15, 16, 17)

18. A computer-readable medium comprising computer-readable instructions for a light-field projector (LFP) comprising a transparent solid-state LED array (SLEA) having a plurality of integrated light-emitting diodes (iLEDs) and a micro-array (MA) having a plurality of either microlenses or micro-mirrors placed at a separation distance from the SLEA, the computer-readable instructions comprising instructions that cause a processor to:
-
identify a plurality of target pixels for rendering on the retina of a human eye, calculate the subset of iLEDs from among the plurality of iLEDs to be used for displaying the pixel, multiplexing the plurality of iLEDs, and cause each iLED among the subset of iLEDs to emit a primary beam of a specific intensity for a specific duration in accordance with best-fit pixel location relative to the MA and corresponding to the target pixel. - View Dependent Claims (19, 20)
