Abstract Submitted to the NANOTUBE'05 Conference:

The exceptional properties of CNT as electron emitters [1] have triggered since the end of the nineties a growing interest to use it in devices like field emission displays (FED). Considering the other leading display technologies, the large size (40 inches diagonal) flat TV market is the most attractive one to introduce a new technology. Thus as a requirement the emerging CNT FED technology must be better in quality and at a lower cost than existing technologies.
To handle such requirements most of the leading display companies develop a low cost approach which is based on printing techniques [2]. In that case, CNT are localised after growth onto the device by using some paste which allows to localise and to connect the CNT with the device structure. While attractive this technology leads to limited display performances.
At LETI direct growth of the CNT onto the device is done by using a CVD process [3]. This kind of technology prefigures future integration of CNT for more complex electronic applications.
The purpose of this paper is to discuss why this approach which uses bottom up and self organisation is able to meet both the cost and quality requirements. Our last results will help to present how far from the target we are and to outline the directions where more basic work is needed in order that our future TV display will integrate few milligrams of this dreaming CNT material.
