Abstract
Provided is a gas excitation display apparatus having a gas excitation display panel and a driving apparatus. In the gas excitation display panel, a gas is excited by electrons emitted from electron emitters, ultraviolet rays are generated from the excited gas and excite phosphor cells, the phosphor cells emit visible light. Each horizontal driving period comprises a horizontal display time and a blanking time. In the horizontal display time, electrons are emitted from the electron emitters by a first electric field and then the emitted electrons return to the electron emitters by a second electric field that is formed in the opposite direction of the first electric field.
