Patent ID: 7728506

Claim:
A flat panel display comprising: a cathode of film emitters; and an anode comprising: a plurality of pixels; a plurality of TFT circuits, each being associated with a corresponding one of the pixels, and applying a known voltage to said corresponding pixel; a conductive frame laterally separating the pixels and substantially isolating their respective electric fields, said conductive frame being in the same plane as the pixels; means for applying said known voltage to said plurality of TFT circuits; a plurality of second transistor circuits connected to said conductive frame; means for applying a voltage proportional to said known voltage to said transistor circuits, said second transistor circuits applying said proportional voltage to said conductive frame; and a row driver associated with each of said plurality of TFT and said plurality of second transistor circuits, said row driver applying a row voltage for selecting selected ones of said plurality of film emitters organized in a row, wherein said row voltage is greater than said known voltage.
