HEAD-UP DISPLAY WITH MULTIPLEXED MICROPROJECTOR
First Claim
1. A head-up display system comprising:
- a microprojector;
first and second viewer optics;
a redirection optic switchable electronically between first and second optical states, the redirection optic configured to receive a display image from the microprojector, to convey the display image, in the first optical state, to the first viewer optic, and to convey the display image, in the second optical state, to the second viewer optic; and
an electronic controller configured to, during a first interval, switch and maintain the redirection optic in the first optical state and cause the microprojector to form the display image based on first image data,the electronic controller configured to, during a second interval, switch and maintain the redirection optic in the second optical state and cause the microprojector to form the display image based on second image data.

Abstract
A head-up display system comprises a microprojector, first and second viewer optics, a redirection optic, and an electronic controller. Switchable electronically between first and second optical states, the redirection optic is configured to receive a display image from the microprojector, to convey the display image, in the first optical state, to the first viewer optic, and to convey the display image, in the second optical state, to the second viewer optic. The electronic controller is configured to, during a first interval, switch and maintain the redirection optic in the first optical state and cause the microprojector to form the display image based on first image data. The electronic controller is further configured to, during a second interval, switch and maintain the redirection optic in the second optical state and cause the microprojector to form the display image based on second image data.

14. A stereoscopic head-up display system, comprising:
-
a microprojector; a right, near-eye viewer optic; a left near-eye viewer optic; a redirection optic switchable electronically between first and second optical states, the redirection optic configured to receive a display image from the microprojector, to convey the display image, in the first optical state, to the right near-eye viewer optic, and to convey the display image, in the second optical state, to the left near-eye viewer optic; and an electronic controller configured to, during a first interval, switch and maintain the redirection optic in the first optical state and cause the microprojector to form the display image based on right-eye image data, the electronic controller configured to, during a second interval, switch and maintain the redirection optic in the second optical state and cause the microprojector to form the display image based on left-eye image data. - View Dependent Claims (15, 16)

17. A head-up display system comprising:
-
a microprojector; a forward viewer optic; a peripheral viewer optic; a redirection optic switchable electronically between first and second optical states, the redirection optic configured to receive a display image from the microprojector, to convey the display image, in the first optical state, to the forward viewer optic, and to convey the display image, in the second optical state, to the peripheral viewer optic; and an electronic controller configured to, during a first interval, switch and maintain the redirection optic in the first optical state and cause the microprojector to form the display image based on forward image data, the electronic controller configured to, during a second interval, switch and maintain the redirection optic in the second optical state and cause the microprojector to form the display image based on peripheral image data. - View Dependent Claims (18, 19, 20)
