Abstract:

In a field emission display (FED) panel, spacers are used to support the anode and cathode substrate. Different distortions of the panel are generated with different spacer distributions.Because distortions of the panels change the distance between the anode and cathode substrates, the internal electric field and the uniformity of emission characteristics is influenced by the spacer distribution.This paper studies the panel distortions with polar spacers and thin wall spacers.It is shown that the equal-lateral triangle patterned spacers are optimal for spacer distribution.Compared with the traditional arrayed pattern, fluctuation of brightness uniformity is reduced by one third.

Key words: FED, optimization, spacer, brightness uniformity
