Abstract:
A zinc oxide(ZnO)field emitter-based backlight unit for liquid crystal display with a gated structure is fabricated by screen-printing processes. The measured anode field emission current density reaches 0.62 mA/cm2 when the applied gate voltage is 570 V. Part of the anode current is contributed by the secondary electron emission which is excited from the MgO layer inside the gate apertures on the gate plate. The average emission current density and luminance are 0.47 mA/cm2 and 1250 cd/m2, respectively, with a fluctuation of about 10% during the 1000 min measurement. By a finite element method calculation, the gated structure shows a good electron beam focusing property. The driving performance of the backlight unit is characterized by SPICE simulation tools and measured by the oscilloscope. Stable field emission, line-by-line scanning and fast response characteristics of the backlight unit indicate its promising application in the liquid crystal displays.
