Abstract
A projection apparatus includes a pixel array disposed on a substrate, where the pixel array has a light-emitting feature; a cantilever beam disposed on the substrate and configured to fasten a micro-electro-mechanical system (MEMS) lens, where the cantilever beam is disposed outside the pixel array, the MEMS lens is configured to scan the pixel array, the cantilever beam and the MEMS lens form a MEMS lens scanner; and a driver coupled to the pixel array and the MEMS lens and configured to drive the pixel array having a light-emitting feature to perform color display to obtain a projected image.
Claims20
An apparatus comprising:
- a substrate;
- a pixel array disposed on the substrate and comprising a light-emitting feature;
- a micro-electro-mechanical system (MEMS) lens scanner comprising:
- a MEMS lens configured to scan the pixel array;
- and
- a cantilever beam disposed on the substrate and outside the pixel array and configured to fasten the MEMS lens;
