전계 방출 디스플레이(Field Emission Display : FED)는 금속 또는 반도체로 만들어진 극미세 구조의 전계 에미터(field emitter)에 전기장을 인가하여 진공 속으로 방출되는 전자를 형광체에 충돌시켜 화상을 표시하는 디스플레이 소자로서, 원리적으로 브라운관(CRT)의 우수한 표시 특성을 그대로 가지면서 경량 박형화가 가능하기 때문에 'Thin CRT'라고 불리기도 한다 FED는 원리적으로 고휘도, 저소비전력, 빠른 응답속도, 광시야각, 고해상도, 우수한 칼라 표시. 넓은 사용온도 범위 등 CRT 및 평판 디스플레이의 장점을 모두 갖추고 있는 이상적인 디스플레이 소자로 평가되어 1990년대 초반부터 세계 유수의 연구 기관들이 본격 적 인 연구 개발을 추진하여 왔지만, 아직까지 평판 디스플레이 시장에 진입 할 만큼 기술 개발이 이루어지지 못하고 있다. 본 고에서는 FED의 근간이 되는 전계방출 소자의 원리 및 종류, FED의 핵심요소 기술, 최근 연구 개발 동향, FED의 응용 분야 및 상용화 가능성 등에 대하여 살펴보기로 한다.

A carbon nanotube field emission display(CNT FED) panel with a 2 inch diagonal size was fabricated using a screen printing of a prepared photo-sensitive CNT paste and vacuum in-line sealing technology. After a surface treatment of the patterned CNT, only the carbon nanotube tips are uniformly exposed on the surface. The diameter of the exposed CNTs are usually about 20 nm. Using the photo-sensitive CNT paste, we have developed a triode type CNT FEA with a self-aligned gate-emitter structure. The turn on voltage was around 100 V which corresponds to according the turn on field of about $40V/{\mu}m$. By the creation of a self-aligned gate-emitter structure, it is expected that the screen printed photo-sensitive CNT paste is promising as a good candidate for the large size field emission display.

Measurements of the direct current resistivity, on multiwalled carbon nanotubes(MWNT) for field electron emitter source that had been screen printed in a thick film form were made as a function of temperature T in the range of 1.7K-390K. In this measuring temperature range, the electrical resistivity for the MWNT show that the main contribution to the conductivity comes form carries that hop directly between localized states executing variable range hopping processes. This thick-film form system for large area display showed a high bright light emission as well as very low turn-on field as like an individual MWNT system at room temperature. Furthermore, the electron emission characteristics followed well typical Fowler-Nordheim conduction under the vacuum.

We have fabricated a carbon nanotube field emission display(CNT-FED) panel with a 2 inch diagonal size using a screen printing method and in-situ vacuum sealing technology. The field emission properties of CNT FED panel with square-type CNT emitters. As results, the square-characterized and compared with those of the line-type CNT emitters. As results, the square-type CNT emitters showed much larger emission current and more stable I-V characteristics. Light emission started to be occurred at an electric field of 3.5 V/${\mu}m$ corresponding to the anode-cathode voltage of 700 V. The vacuum level inside of the in-situ vacuum sealed panel was obtained with $1.4 {\times} 10^{-5}$ torr. The sealed panel showed the similar I-V characteristics with the unsealed one and the uniform light emission with very high brightness at a current density of $243 {\mu}A/ cm^2$ obtained by the electric field of 10 V/${\mu}m$.

Since the discovery over a decade ago, carbon nanotubes (CNTs) have been attracting considerable attentions both from scientists and engineers. Because of the excellent field emission properties, such as high aspect ratio, extremely small diameter, and high emission current, CNTs become a potential candidate as field emitter for field emission display (FED) and lighting (FEL) as backlight for LCD. Due to the exceptional physical properties, such as superior thermal and electrical conductivities, as well as high stiffness and strength, the CNT-based composites can be as light-weight heat-sink or thermal spreader materials used for power electronic devices, such as power LED for general illumination. The CNTs for above applications will be reviewed, and related materials and devices will be demonstrated in this paper.
