Method for a sealed cell assembly on silicon

Disclosed is a method for a sealed cell assembly on silicon. Benefits include improved ease of manufacturing and improved usability.

Background

        � � � � � The use of silicon technology that enables a projection system on the silicon is an emerging market opportunity.

Description

        � � � � � The disclosed method is a sealed cavity (cell) on silicon that can be filled with liquid or gas material (see Figure 1). When implemented in an application, the silicon die creates an image that can be projected onto a screen.� The silicon has metal pixels on the silicon backplane. The sealed cavity houses liquid crystals that act as an agent to create an image. Polarized light is transmitted through the liquid crystals onto the metal pixels.

        � � � � � The cavity is made watertight by glue or epoxy and a top cover slip that acts as a clear lid to the sealed cavity. It is assembled directly on the surface of the die.

        � � � � � The target market for the disclosed method is a large screen projection device. This method offers cost savings and reduced weight from conventional image projection techniques.

Advantages

        � � � � � The disclosed method provides advantages, including:

•        � � � � Improved functionality due to the use of silicon and liquid crystals to enable image projection

•        � � � � Improved usability due to improved weight
