Embodiment Construction
[0069] As shown in FIG. 6, a scanned beam display 40 according to one embodiment of the invention is positioned for viewing by a viewer's eye 44. While the display 40 is presented herein as scanning light into the eye 44, the structures and concepts described herein can also be applied to other types of displays, such as projection displays that include viewing screens, as well as other types of scanning apparatuses.
[0070] The display 40 includes four principal portions, each of which will be described in greater detail below. First, control electronics 74 provide electrical signals that control operation of the display 40 in response to an image signal VIM from an image source 76, such as a computer, television receiver, videocassette player, DVD player, remote sensor, or similar device.
[0071] The second portion of the display 40 is a light source 50 that outputs modulated light beams 52, each having a modulation corresponding to information in the image signal VIM. The light sou...
