Field emission displays

Objective

Extension of the performance envelope associated with PixTech's FED, towards higher brightness and power efficiency. FED technology improvements include :
An anode with a voltage stand-off up to 600 V.
A transparent cathode for an inverted structure allowing a brightness improvement of a factor 2 relative to the standard structure.
New phosphors with a mean luminescence efficiency of 3 lm/W in the white.
Demonstration and full testing of 5.2'' 1/4 VGA, full colour display with following basic characteristics:
Luminance 150 cd/m2 in operation
Contrast ratio 12:1 in a 500 lux ambient light
6 to 8 bits grey scale depending on market requirements
More than 5000 hours lifetime in full white
Further development of FED specific materials and equipment, including holographic exposure equipment :
The hologram masks with 0.6 um microhole diameter
Zero defect holograms
Equipment specification targeted to a production machine, with automated substrate handling system, a production friendly H-Mask changing system, an on-axis illumination system for the alignment and an environmental control system.

Building on the foundations of AIMFED, and taking into account the specific requirements of European instrumentation for transport and industrial markets in the area of displays, FED is a focused R&D program leading to an extension of the FED performance envelope towards higher brightness and power efficiency. The display will be, by the end of month 18, a 1/4 VGA, 5.2", 150 cd/m2 full colour display.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Call for proposal

Procedure for inviting applicants to submit project proposals, with the aim of receiving EU funding.
