<p>A support structure (3) is provided that enables use of high voltage phosphors in field-emission flat panel displays, to maintain vacuum gap (4) between the cathode (2) and anode (1), and to prevent distortion of the transparent view screen and backing plate of the display. A number of techniques contribute to the solution of the problem of secondary electron emission. In accordance with one technique, the geometry of the triple junction of the support structure, the cathode and the vacuum gap is altered. In accordance with another technique, the support structure is fluted so as to reduce the average coefficient of secondary emission. In another technique, a high resistivity conductive layer is formed at the triple junction in order to reduce electric field potential at the triple junction. In accordance with another technique, the support structure is made of a non-porous material and may be coated with a coating having low secondary emission characteristics.</p> |
