ABSTRACT:
The invention relates to methods and apparatus for forming a display apparatus. According to one aspect of the invention, the display apparatus includes a first substrate having an aperture layer formed thereon, a light guide for guiding light towards the aperture layer, a plurality of MEMS light modulators for modulating light passing through the aperture layer from the light guide, and a spacer substantially surrounding the light guide for keeping the light guide and the first substrate a predetermined distance apart from one another, thereby forming a gap between the first substrate and the light guide. Alternatively or in addition, the first substrate may have a control matrix formed thereon.
