Conductive focus waffle
摘要:
A conductive focus waffle structure for focusing electrons emitted from a cathode portion of a flat panel display device. In one embodiment, the conductive focus waffle structure comprises a grid of material comprised of substantially orthogonally oriented rows and columns. The substantially orthogonally oriented rows and columns define openings therebetween having sufficient size to allow electrons emitted from a cathode portion of a flat panel display device to pass therethrough. The focus waffle grid further comprises a lower dielectric portion adapted to be coupled to the cathode portion of the flat panel display device and an upper conductive portion coupled to the lower dielectric portion, the upper conductive portion adapted to focus the electrons passing through the openings.
