Abstract
A flat panel display device is divided into channels and includes deflection electrodes for scanning electron beams horizontally across the channels. Convergence electrodes are voltage biased to converge the electron beams at points along the transverse line scanned by the electron beams. A compensation voltage generator provides compensation voltages to compensate for horizontal landing errors of the electron beams.
