Kopin Develops Ground-Breaking Nanojet Process for Liquid Crystal Cell Assembly

Kopin® Corporation, a leading developer of innovative wearable computing technologies and solutions, announced that it has developed a revolutionary NanoJet process for its liquid crystal cell assembly.

The NanoJet process releases tiny drops of liquid crystal material with greater precision (variation within a few nano grams) and provides for a purer, better controlled and very uniform layering of the liquid crystal material in the fabrication of displays, resulting in superior image quality and higher brightness.

“The patent-pending Nanojet process developed at Kopin is optimized for microdisplays with tiny pixels required for augmented reality (AR) and virtual reality (VR) applications,” said Dr. John C.C. Fan, President and CEO of Kopin Corporation. “This process improves the display performance and reduces the cost to manufacture the display. The Nanojet process can be used in the manufacture of both our transmissive Cyberdisplay® and reflective LCOS displays. We are qualifying the NanoJet process and expect a tier-one customer to introduce in coming months a wearable product which includes a display manufactured using the Nanojet process. It is our intention to apply this superior process to many of our current products where ever possible.”

Advantages of the NanoJet process include:

  • Maintenance of purity of the liquid crystal in the display fabrication process
  • Excellent control of cell gap and cell gap uniformity across the wafer and within each display, even for large (~1” diagonal) high-resolution microdisplays for VR without the use of posts inside the display
  • Reduced display cost due to higher manufacturing yield and less liquid crystal material usage

Display performance improvements include:

  • Superior image quality
  • Much higher display brightness: in excess of 10,000 nits for full-color displays with tiny pixels (3 x 9 μm) typically needed for smart headsets.
  • Increased high temperature operating range
