Study of high-brightness flat-panel lighting source using carbon-nanotube cathodeThe authors investigated a full sealed flat-panel light source, which is based on a triode structure with a metal mesh gate electrode and uses a carbon nanotube cold cathode. It has a flat surface luminance distribution with good uniformity, a stable luminance of 12 000 cd/ m 2 , and a luminous efficiency that was measured to be 14.5 lm/ W. It also shows a high color rendering index of 88 and a wide optical emission spectrum. Further, its application as thin film transistor-liquid-crystal display ͑TFT-LCD͒ backlight was demonstrated and the resulted performance of the TFT-LCD display was studied and compared to the commercial TFT-LCD products, which use the cold-cathode fluorescent lamp backlight and light emitting diode backlight. It is shown that the light transmission ratio in the TFT-LCD module using our light source is ϳ8%, as compared to ϳ4% of the commercial products. With this and the very high luminance, our light source is very useful to the situation, in which the TFT-LCD screen is employed to work under outdoor sunshine conditions.

“…High-quality field emitters are desirable for a wide range of field-emission-based devices, such as flat-panel displays [1], X-ray sources [2], microwave-generation devices [3], and high-efficiency lamps [4]. Recently, several strategies, including doping [5], surface decoration [6], patterned growth [7], and the use of conductive substrates [8], have been employed to improve the performance of field emitters.…”

“…These superior properties and their distinctive geometric feature of extremely high aspect ratios [3] makes CNTs particularly suitable for field emission applications [1] such as flat lamps [4], flat panel displays [5,6] and X-ray sources [7,8]. Many techniques-including direct CVD growth [9], dip coating [10], screen printing of CNT pastes [11], electrophoresis [12], spray coating [10] and vacuum filtration [13]-have been used to fabricate CNT field emitters, but screen printing is the favoured technique because it enables simple, low-cost and large-area processing.…”
