Abstract
Embodiments of adjusting an optical characteristic are disclosed.
Claims23
A method comprising:
- adjusting sets of one or more subpixels within different ones of a plurality of groups of subpixels to have an optical characteristic so that the sets of one or more subpixels have the optical characteristic during a time interval, wherein the sets of the one or more subpixels within different ones of the plurality of groups of subpixels are arranged in a reverse serpentine pattern.
An apparatus comprising:
- a screen comprising a plurality of elements each having an adjustable optical characteristic and arranged into a plurality of groups;
- and
- a plurality of electrodes, with individual ones of the plurality electrodes coupled to one or more of the elements included in different ones of the plurality of groups, wherein the plurality of electrodes have a reverse serpentine shape.
A computer-readable medium comprising:
- stored instructions to adjust sets of one or more subpixels within different ones of a plurality of groups of subpixels to have an optical characteristic so that the sets of one or more subpixels have the optical characteristic during a time interval;
- and
- stored instructions to apply a voltage potential to select ones of the subpixels to provide a dithering configuration in a reverse serpentine pattern.
A method comprising:
- step for providing a plurality of projected pixels onto a screen having a plurality of subpixels on the screen in regions corresponding to each of the projected pixels;
- step for causing an optical characteristic of one or more of the subpixels to change;
- and
- step for dithering the plurality of subpixels in a reverse serpentine pattern.
1 more element
An apparatus comprising:
- means for adjusting an optical characteristic of one or more of subpixels of the screen for providing a plurality of optical characteristic levels on the screen, wherein an area corresponding to a projected pixel on the screen comprises a plurality of the subpixels;
- and
- means for dithering the plurality of subpixels in a reverse serpentine pattern for providing the plurality of optical characteristic levels.
