摘要

通过酸化、球磨、超声分散等工艺制备碳纳米管(Carbon Nanotubes

CNT)悬浮液

利用电泳沉积技术制备CNT阴极

并对器件的场致发射性能进行测试。结果表明

当电场为1.76 V/m时

CNT场致发射平面背光源器件的亮度为6 500 cd/m

亮度均匀性为89％

可应用于液晶显示器的背光源。

Abstract

The carbon nanotubes (CNT) cathodes were obtained by electrophoretic deposition (EPD) and sealed into a prototype of 25.4 cm (10 in) field emission backlight units (FE-BLU). The electrophoresis suspension with CNT was fabricated by a series of processes which included acid-treating

ballmilling and ultrasonic dispersing

and so on. The morpho-logy of CNT cathode sample was observed by scanning electron mircroscope (SEM). The field emission properties of FE-BLU were characterized in vacuum

which can be applied to LCD. Results showed that CNT FE-BLU demonstrated a good performance of luminance brightness 6 500 cd/m

with electric field of 1.76 V/m

and the brightness uniformity was up to 89%.
