Abstract
An alignment layer is provided over liquid crystals for a display. Alignment marks are laser-written on the alignment layer, such that the liquid crystals become aligned with one another.
Claims24
A method comprising:
- providing an alignment layer over a plurality of liquid crystals for a display;
- and,
- laser-writing a plurality of alignment marks on the alignment layer, such that the liquid crystals become aligned with one another.
A display formed by performing a method comprising:
- providing an alignment layer relative to which a plurality of liquid crystals for the display is to be disposed;
- and,
- at least one of:
- laser-writing a plurality of homogenous alignment marks at least substantially parallel to a surface of the alignment layer;
- and,
- laser-writing a plurality of homotropic alignment marks at least substantially perpendicular to the surface of the alignment layer.
3 more elements
A display comprising:
- a substrate;
- an alignment layer over the substrate and having a plurality of laser-written alignment marks on a surface thereof;
- and,
