Patent ID: 7652811

Claim:
A method, comprising: positioning a light concentrating component, having a body comprising a near end and a far end, an exit pupil at the far end, and an internal reflective surface shaped and dimensioned to concentrate light entering the body at the near end to exit the body at the far end via the exit pupil, to a position relative to a modulating component in which position, light exiting the body through the exit pupil impinges on an active area of the modulating component; and securing the light concentrating component relative to the modulating component in said position; wherein the modulating component comprises a subpixel, an active area of which is defined by a mechanical shutter having an aperture, the shutter being laterally displaceable, by a laterally actuating comb drive, relative to the light concentrating component to change the relative positioning between the exit pupil of the light concentrating component and the aperture of the mechanical shutter.
