Autostereoscopic display
First Claim
1. An autostereoscopic display having (a) a surface which can generate or transmit regions of emitted light, (b) a transmissive display or reflective light valve display spaced apart from said surface, (c) an optical element located near said transmissive or reflective light valve display and being generally of the same dimensions as said display which focuses light from the light emitting regions on the first surface onto a plane spaced apart from said display, (d) means to cause the regions which emit light to blink on, then off, one after the other, and to continuously repeat the process, and (e) means to cause the image on said transmissive or reflective light valve display to change rapidly so that a different image can be shown each time a different light emitting region is turned on, the improvement being that of additionally providing:
- an optical element located near said transmissive display and being generally of the same dimensions as said transmissive or reflective light valve display, which focuses light from the light emitting regions on the first surface onto a plane spaced apart from said display,whereby improved brightness of the display is obtained.

Abstract
An autostereoscopic display with an optical element inserted near the transmissive display has improved brightness of the display, and optionally has incorporated therein a head position sensing device capable of sensing the position of at least one observers head causing the light emitting regions of the device to move in response to data on the observer'"'"'s head position provided by the head sensing device.
