Abstract
A plasma display and a driving method thereof are disclosed. The plasma display includes a power supply that supplies a plurality of voltages to a driver driving first electrodes through a plurality of fuses. The power supply supplies the plurality of fuses with a fuse driving voltage used to control the plurality of fuses. When an error occurs in the driver connected to a first fuse, the fuse driving voltage is not supplied to the plurality of fuses. Then, the entire operation of the driver is stopped. Therefore, elements of the driver, in which errors do not occur, can be prevented from being further damaged.
