Methods for manufacturing cold seal fluid-filled display apparatus
First Claim
1. A method for manufacturing a display assembly including a first transparent substrate and a second transparent substrate, comprising:
- cooling the first and second transparent substrates to a first temperature;
applying a fluid to at least one of the first and second transparent substrates, wherein the fluid is applied at an equilibrium vapor pressure substantially the same as a vapor pressure of the fluid;
aligning the first and second substrates; and
curing a seal material to seal the fluid between the first and second substrates along a perimeter thereof.

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 form 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.
