Development of an ac plasma display panel with a low discharge voltage utilizing an electrophoretic carbon nanotube as a field emission layer

Abstract

A kind of plasma display panel with a carbon nanotube (CNT) field-emission layer on the dielectric layer of the front panel was proposed and a prototype was prepared with the CNT layer fabricated by an electrophoretic deposition technique. The CNT layer was designed at the middle of an ITO electrode by a 2D fluid simulation, and the bus electrode with the same width was aligned with the CNT layer which can avoid obscuring the emanating visible light from phosphor. The effective CNT pretreatment, and uniform and thickness distribution of CNTs in the layer resulted in the excellent field-emission properties of the CNT layer. The minimum sustaining voltages were decreased by 30-40 V with the used CNT layer being underneath the MgO layer in a series of discharge testing.

High performance field emission cathode based on the diamond nanowires prepared by nanocrystalline diamond films annealed in air

“…Compared with NCD films, the 1332 cm −1 peak of diamond increases significantly, and the sp 3 /sp 2 area ratio rises from 0.36 to 0.69. This is due to the faster oxidization of sp 2 than that of sp 3 which is also the mechanism to form diamond nano-structure by annealing NCD under the oxidation atmosphere.…”

“…Field electronic emission can achieve stable current at room temperature with high efficiency, low power consumption, fast response, and ease of miniaturization, resulting in a wide range of application scenarios and great potential [1]. Carbon nanotubes, graphene and diamond are three allotropes of carbon, which have unique microstructures and excellent electron emission characteristics [2], and have been widely used in display devices [3,4], ion-sorption vacuum pump [5], microscopic imaging [6], switching devices [7] and electric thrusters [8].
