Fabrication of Carbon Nanotubes Field Emission Backlight Unit Applied to LCD

Carbon nanotubes (CNTs) are known for their excellent emission properties because of their own characteristics. This paper described the fabrication of a new planar field emission backlight unit (FE-BLU) with CNTs. The CNT cathodes were prepared by screen-printing on elaborate Ag electrodes and sealed into a prototype of 10-inch FE-BLU after CNTs had been chemical modified. The results showed that the CNT cathode had good field emission properties, with low turn-on electric field of 1.0 V/�� m, the current density of 7.0 mA/cm 2 at the electric field 3.0 V/��m, and high luminance brightness of 5300 cd/m 2 . Moreover, the CNT FE-BLU demonstrated a good performance of luminance brightness 3200 cd/m 2 without significant degradation after 80 days.

We present the performance results of 34-inch field emission display (FED) prototypes which can display full-color video with luminance of ∼400cd/m2, contrast ratio of 1000:1, circuit gray scale of 256. It is constructed using low work function (LWF) printable cathode, insulated film, under-gate, spacers and color phosphors.

A stable backgated-type SnO 2 2 nanowires field emitter for mass production

In this paper we report the fabrication and testing of backgated triode structure field emission (FED) devices with SnO<inf>2</inf>-nanowires-based cathodes. Field-emission measurement reveals that the SnO<inf>2</inf>-nanowires FED devices posses a good emission property with low turn-on voltage (∼150 V), high emission current (∼ 390 µA) and long-term emission stability.

The study of a tetrapod-like nanostructure ZnO field emission display

A tetrapod-like ZnO nanostructures prepared by hyperthermia vapour phase oxidation process were used as the field emission cathode material. The field emission cathode panel prototype is fabricated with ZnO slurry printed and sintered. We packed the cathode panel and the fluorescence panel on which was printed with phosphor power as a 5 inch field emission display of diode structure. The field emission experiments were done and the panel realized stable field emission, it could display simple characters. The turn-on electric field of diode structure ZnO-FED is 1.5V/µm. When the electric field reaches 5.3V/µm, the emission current density can approach to 5.11µA/cm2. We had obtained the electric field enhance factor about 6772 by the experiment. It has shown from the experimental results that tetrapod-like ZnO nano-material has good electron emission performance and it is also a beautiful field emission cathode material.
