Abstract
According to the invention, a process is provided for controlling illumination of a pixel in a field emission display. In one embodiment, the process includes the steps of providing a first voltage to the first tip array, providing a second voltage to the second tip array in which the second voltage is different than the first voltage. In another embodiment of the invention, a field emission display is provided which has a plurality of pixels, each pixel having at least a first tip array and a second tip array, a column conductor, or electrode, an electrical communication with the first tip array.
