Large-area color nanotube FED debuts
The Samsung Advanced Institute of Technology (SAIT) at the Samsung corporate R&D center (Suwon, Korea) has unveiled what it believes is the world's first large-area color carbon nanotube field-emission display (CNT-FED). At the International Display Workshop '99 (December 1999; Sendai, Japan), the research institute showcased a 9-in.-diagonal, full-color prototype device with 200 x 120-µm pixels and 576 x 240-line resolution (smaller pixels are possible).
The CNT-FED offers three colors at every pixel, and color separation occurs without crosstalk. Other features include a fast response rate, low power consumption, wide viewing angles, a wide operating temperature range, and display brightness of 200 cd/m2 at 3 V/µm.—Paula Noaker Powell
