Abstract: Methods for minimizing the errors associated with substrate etching are presented. The methods use intentional defocusing of the pattern image on the photoresist to minimize errors in the etching process particularly grayscale etching and/or multiple exposure contributions from neighboring patterns.

Abstract: An autostereoscopic display and method of displaying multidimensional images involves a first lenticular array preferably of cylindrical lenses positioned between a viewer and a pixel array, and a second lenticular array also preferably of cylindrical lenses positioned between the first lenticular array and the viewer. The pixel array includes several pixel groups that project images through corresponding groups of first lenses within the first lenticular array. A pitch of the lenses within the second lenticular array differs from a pitch of the lenses in the first lens groups within the first lenticular array. The display can be manufactured or retrofit with the first and second lenticular arrays.
