摘要：
Techniques and architectures for providing a coating for one or more micro-lenses of a pixel array. In an embodiment, a pixel element includes a micro-lens and a coating portion extending over a surface of the micro-lens, where a profile of the coating portion is super-conformal to, or at least conformal to, a profile of the micro-lens. In another embodiment, the coating portion is formed at least in part by orienting the surface of the micro-lens to face generally downward with the direction of gravity, the orienting to allow a fluid coating material to flow for formation of the coating portion.
