Assignee: ADVANCED SILICON DISPLAY OPTOELECTRONICS CORPORATION LTD.
Field: Optics (Instruments)
Classification: CPC G  H | IPC G  H

Claim 10:
11. An LCoS panel, comprising:
a wafer substrate comprising:
a silicon substrate comprising a first surface and a second surface opposite to the first surface,
an active circuit arranged on the first surface, comprising a pixel circuit area and a peripheral circuit area,
a plurality of conductive interfaces arranged on the second surface, and
a plurality of vias extending through the first surface and the second surface, each of the plurality of conductive interfaces is arranged to correspond to one of the plurality of vias, and electrically connected to the active circuit by a corresponding one of the plurality of vias;

a glass substrate comprising a transparent conductive layer, and being opposite to the wafer substrate;
a seal arranged between the wafer substrate and the glass substrate, surrounding the pixel circuit area of the active circuit and defining a liquid crystal space; and
liquid crystal in the liquid crystal space;
wherein an enclosed space filled with the liquid crystal is defined by coupling a surface of the glass substrate with the transparent conductive layer and the wafer substrate by the seal, and one of the plurality of conductive interfaces is configured to electrically connect the LCoS panel to an external circuit substrate; and projections of the plurality of vias on the wafer substrate surround and keep away from the pixel circuit area.
