Abstract:

     The development of a new type of field-emitter-based display
for NASA is the goal of this project. These field-emitter displays
have the potential to provide high-resolution pixels, high
brightness, full color, wide viewing angle, high energy
efficiency, and low driver cost. They would be flat and possess
small overall volume. The displays will be built from the
company's unique, etched emitter tips with self-aligned gates.
This workstation application will permit the level display devices
to be designed to operate at high voltage levels, approaching the
level of CRTs, where high-efficiency phosphors are commonly
available. High levels of emitter redundancy are coupled with
vertical current flow through current limiting resistors. First,
this project will develop a near-ideal workstation display for
many applications, including those in space. Next, this project
will demonstrate the feasibility of a process to improve yield,
economy, reliability, and performance of field-emitter displays
using etched emitters instead of evaporated emitters. The project
would produce in Phase II a static, addressable array of pixels on
a 50 mm x 50 mm field and would develop an over one million pixel
usable video display.

Potential Commercial Application:

Potential Commercial Applications:  The display can be used in
workstations, portable electronics, and other handheld
instruments; avionics; control panels; virtual reality and/or
three-dimensional, wall-hanging, high-definition television;
projection TV; multimedia, printing, and other display, indicator
or light panel applications.
