ABSTRACT:
An electron emission display includes a display panel having a first substrate on which at least one first electrode is formed, a second substrate on which a second electrode and a third electrode on which an electron emission source is formed are formed. A fourth electrode is formed between the first and second substrates to focus towards a corresponding phosphor surface area on the at least one first electrode the electrons emitted by the electron emission source towards a corresponding phosphor surface area on the at least one first electrode, the second electrode being insulated from the third electrode and crossed therewith. A scan electrode driver applies scan pulses to the second electrode. A data electrode driver applies data pulses to the third electrode. A focusing electrode driver applies focusing voltages to the fourth electrode. The focusing electrode driver applies different voltages according to image displayed states on the display panel.
