Current-regulated field emission cathodes for use in a flat panel display in which low-voltage row and column address signals control a much higher pixel activation voltage |
摘要 |
In a flat panel display in which low-voltage row and column address signals control a much higher pixel activation voltage by respectively gating at least one pair of series coupled MOSFETs to ground for each pixel, effective current regulation is achieved by placing a current-regulating resistor in series with each pair of the series-coupled MOSFETs. The resistor is coupled directly to ground and to the source of the MOSFET furthest from the emitter node. By coupling the current-regulating resistor directly to the ground bus, stable current values are achieved over a wide range of cathode voltages.
