Abstract
A power module for a field emission display and a method of power generation are described. More particularly, the power module and method of power generation both are for the field emission display in diode structure. The power module has a direct current (DC) power source, a pulse width modulation circuit connected to the DC power source for generating a pulse width modulation signal, an electronic switch connected to the pulse width modulation circuit for receiving the modulation signal so as to convert the DC power into a high-frequency alternating power supplied to the primary side of a transformer. Moreover, the second side of the transformer generates a high-voltage and a high-frequency power source to the field emission display.
