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

Claim 11:
12. An LCoS panel, comprising:
a wafer substrate comprising:
a silicon substrate comprising a first surface and a second surface opposite to the first surface, the first surface comprising an active circuit, the active circuit comprising a pixel circuit area and a peripheral circuit area, the second surface comprising a plurality of conductive interfaces, and a thickness of the silicon substrate ranges from 220 um to 500 um; and
a plurality of vias extending through the first surface and the second surface, wherein each of the plurality of conductive interfaces is arranged to correspond to one of the plurality of vias, and is electrically connected to the active circuit by a corresponding via; and
a transparent substrate comprising a transparent conductive layer, the transparent substrate being opposite to the wafer substrate;
a seal between the wafer substrate and the transparent substrate, wherein the seal surrounds the pixel circuit area of the active circuit and defines a liquid crystal space; and
a liquid crystal injected in the liquid crystal space;
wherein the plurality of conductive interfaces electrically connects the LCoS panel to an external circuit substrate, and projections of the plurality of vias on the wafer substrate surround but do not intercept with the pixel circuit area.
