“…Because field emission displays (FED) require a highvacuum operation condition to optimize the life-time of electron field-emitters, 1,2) vacuum spacers, 3) which keep the phosphor anode and the emitter cathode separated at a fixed distance, are used to withstand the atmospheric pressure. The vacuum spacers should be able to sustain high voltage between the two electrodes without electrical breakdown.…”

Porous surface structures can mitigate the charging effect of vacuum spacers of field-emission flat panel display due to the abundance of secondary electrons (SEs) emitted from the spacers during field emission display (FED) operation. In this study, we fabricated porous anodic aluminum oxide (AAO) overlayers on glass substrates to examine the effect of carbon deposition on the reduction of SE emissions. This paper reports that uniform AAO overlayers can be simultaneously prepared on both sides of a glass plate 2 Â 10 cm 2 in size. The SE emission of the AAO overlayer was examined by using an Auger electron microscope. When a small amount of carbon is evaporation-deposited on the asprepared AAO overlayer, the SE emission efficiency is significantly decreased and the reduction in the SE emission is ascribed to the low SE yield of the carbon deposit and the suppression of SE escape from the narrowed pore channels. However, a heavy deposition of carbon results in a smaller surface roughness of the AAO overlayer, thereby increasing SE emission. The carbon-coated AAO overlayer demonstrates favorable electrical and mechanical properties, making it suitable for use in FED vacuum spacers.

The spacers placed transversely and lengthwise which are used for supporting 960 540 mm 2 FEDs are simulated by ANSYS finite element method. To obtain optimum spacer structures, the stress distribution and the maximum deflection are calculated. By considering the negative effects of spacers, two optimal spacer structures that cause acceptable deflection of the panel are found. Spacers with a length of 162mm, transverse spacing of 25mm and lengthwise spacing of 30mm are used in transversely structure. While spacers are distributed lengthwise with a length of 147mm lengthwise spacing of 25mm and transverse spacing of 30mm. From the comparison of the areas the spacers occupied in the two spacer structures, the lengthwise structure should be commended to be applied.
