Abstract: The present invention relates to a field emission display using a gated field emitter and a flat electrode that is applied to a Cathode Ray Tube (CRT). The present invention does not need a spacer unlike the related invention and so the problem resulting from a mounting of the spacer is solved, and the structure of its whole panel and its fabrication process are simplified, thus improving its productivity and decreasing its fabrication cost.

Abstract: A circuit for automatically substituting a reference oscillator for synchronizing two transmitter co-channel local oscillators. The circuit includes a first bias switching device for switching a first power supply to a first reference oscillator and a second bias switching device for switching a second power supply to a second reference oscillator. The first and second reference oscillators generate first and second reference signals for synchronizing the oscillator frequencies. A first divider firstly and secondly divides and outputs the power of the first reference signal. A second divider firstly and secondly divides and outputs the power of the second reference signal. A first combining device inputs the power of the firstly-divided first reference signal and the secondly-divided second reference signal and outputs the power to the phase locked dielectric resonator oscillator for the vertical polarization wave.
