摘要：

A 5-inch diagonal parallel-gated backlight unit for a liquid crystal display (LCD) was fabricated using carbon nanotube (CNT) paste. A brightness of 10,000 cd/m(2) was demonstrated at 10 KV of anode voltage, and 31 lm/W of light efficiency (for P-22 white phosphor) was obtained. We inserted a mesh electrode with appropriate apertures between anode and cathode plates, which suppressed charge-up effects on the exposed insulator surface and dark electron emission induced by the anode voltage. Such a simply structured backlight is expected to be cost-effective for applications in large-area LCD TVs.
