First Claim
1. A method for manufacturing a display assembly including a first transparent substrate and a second transparent substrate comprising:
- providing at least a portion of an array of light modulators on the second transparent substrate;
providing a plurality of spacers connected to the first and second transparent substrates to establish a first gap between the first and second transparent substrates;
providing an adhesive edge seal for bonding the perimeter of the first and second transparent substrates;
filling the display assembly with a fluid at a first temperature;
cooling the display assembly to a second temperature substantially below the first temperature;
compressing the display assembly thereby pushing the first and second transparent substrates at least partially together; and
curing a seal material to seal the fluid between the first and second transparent substrates.

Abstract
This methods and devices described herein relate to displays and methods of manufacturing cold seal fluid-filled displays, including MEMS. The fluid substantially surrounds the moving components of the MEMS display to reduce the effects of stiction and to improve the optical and electromechanical performance of the display. The invention relates to a method for sealing a MEMS display at a lower temperature such that a vapor bubble does not formforms only at temperatures about 15° C. to about 20° C. below the seal temperature. In some embodiments, the MEMS display apparatus includes a first substrate, a second substrate separated from the first substrate by a gap and supporting an array of light modulators, a fluid substantially filling the gap, a plurality of spacers within the gap, and a sealing material joining the first substrate to the second substrate.
