Abstract
A method for driving a field emission display (100) includes the steps of applying a drive signal (146) to an emission electrode (113) and manipulating the drive signal (146) using a feedback controller to control an electrode voltage signal (158) at the emission electrode (113). A field emission display (100) includes a field emission display device (110), a feedback controller (123), and a current source (120). The current source (120) is connected to an input (144) of the field emission display device (110). An output (131) of the feedback controller (123) is connected to an input (127) of the current source (120), and the input (144) of the field emission display device (110) is connected to the input (129) of the feedback controller (123).
