Kopin has developed and introduced a new production process for its reflective LCoS and transmissive Cyberdisplay microdisplays. The Nanojet system is designed to produce a purer, more uniform layering of liquid crystal material in display fabrication, resulting in higher image quality.
Kopin says that the process releases ‘tiny drops of liquid crystal material’ with greater precision than previous systems – with a variation of only a few nanograms. It is optimised for the very small pixels required for augmented and virtual reality applications. A tier one customer is expected to introduce a wearable product using a display manufactured with Nanojet in the coming months.
In addition to the control of the cell gap and cell gap uniformity across the wafer, Nanojet is said to enable much higher display brightness: in excess of 10,000 cd/m² for full-colour displays with very small pixels (3 x 9µm).
