Classification: CPC G | IPC G

Claim 9:
10. A liquid crystal on silicon (LCOS) panel, comprising:
a first portion, comprising:
a backplane with an electrical contact and a plurality of pixel electrodes formed in the backplane; and
a first alignment layer disposed on the backplane and interfacing with the electrical contact;

a second portion, comprising:
a conductive layer that is light transmissive; and
a second alignment layer disposed on the conductive layer;

a plurality of spacer beads in a non-electrically-conductive adhesive,
wherein the non-electrically-conductive adhesive forms a wall between the first portion and the second portion, and the plurality of spacer beads defines a gap between the first portion and the second portion;

a liquid crystal fluid inside of the wall between the first portion and the second portion and surrounded by the wall; and
a plurality of beads in an electrically-conductive adhesive between the first portion and the second portion outside of the wall,
wherein electrically-conductive particles within the electrically-conductive adhesive make the electrically-conductive adhesive electrically-conductive,
wherein sizes of the electrically-conductive particles are smaller than sizes of the plurality of beads, and
wherein an electrical connection of the electrical contact and the conductive layer is via sat least one of:
a first set of the electrically-conductive particles that are in contact with both the first alignment layer and the electrical contact, or
a second set of electrically-conductive particles that are in contact with both the second alignment layer and the conductive layer.
