Abstract
An apparatus includes a light source, a display array, a light relay, a photodetector, and control circuitry. The light source is for providing lamp light during an ON-time of the light source. The display array is positioned to receive and selectively manipulate the lamp light. The light relay is positioned to receive the image light from the display array. Control circuitry is coupled to the light source for adjusting the light source and coupled to receive an output of the photodetector.
Claims12
An apparatus for a head mounted display (“HMD”), the apparatus comprising:
- a light source including a first, second, and third light emitting element for sequentially providing, respectively, first, second, and third color lamp light;
- a display array positioned to receive and selectively manipulate the first, second, and third color lamp light to generate a color sequential image;
- a light relay positioned to receive the color sequential image from the display array and to deliver the color sequential image to a viewing end of the light relay for presenting to an eye of a user when the HMD is worn;
- a photodetector optically coupled to receive ambient light from the light relay and optically coupled to receive the first, second, and third color lamp light;
- and
- control circuitry coupled to receive an output of the photodetector and coupled to the light source for sequentially cycling the first, second, and third light emitting elements based on the output of the photodetector.
An apparatus for a head mounted display (“HMD”), the apparatus comprising:
- a light source for providing lamp light during an ON-time of the light source;
- a display array positioned to receive and selectively manipulate the lamp light to generate computer generated image (“CGI”) light;
- a light relay positioned to receive the CGI light from the display array and deliver the CGI light to a viewing end of the light relay for presenting to an eye of a user;
- a photodetector optically coupled to receive ambient light from the light relay;
- and
- control circuitry coupled to receive an output signal of the photodetector and coupled to the light source for adjusting the ON-time of the light source based on the output signal of the photodetector.
