An equalizer that processes blocks of data includes a first finite filter which applies first finite filter coefficients to the blocks of data and a first post-processor which applies first post-processor coefficients to an output of the first finite filter. An odor reducing photocatalytic material is provided on an outside surface of the envelope, the photocatalytic material being coextensive with the ultra-violet light reflecting material. In addition to the resonant cavity structure, the light-emitting structure also includes a contact layer, an n-type metal electrode and a p-type metal electrode. First sourcedrain terminals are row addressable by interconnection lines disposed substantially parallel to the first gate lines.
