Flat panel display and method of driving the flat panel display

A method of driving a flat panel display having a pixel portion having a plurality of pixels, a scan driver supplying a plurality of scan signals to the pixel portion, a data driver outputting a plurality of data signals to be supplied to the pixel portion and a demultiplexer portion sequentially supplying initialization signals and the data signals to the pixel portion, the demultiplexer portion including a plurality of demultiplexers receiving corresponding ones of the data signals, the method comprising:

• supplying respective ones of the data signals to respective data inputs of each demultiplexer;
• supplying an initialization signal to an initialization signal input of each demultiplexer;
• supplying first, second and third control signals to respective first, second and third control signal inputs of each demultiplexer;
• turning on or off first, second and third switching transistors connected to each of the data inputs of each demultiplexer, the first switching transistor being operatively controlled by the first control signal, the second switching transistor being operatively controlled by the second control signal and the third switching transistor being operatively controlled by the third control signal;
• turning on or off first, second and third initialization transistors connected to the initialization signal input of each demultiplexer, the first initialization transistor being operatively controlled by the third control signal, the second initialization transistor being operatively controlled by the first control signal and the third switching transistor being operatively controlled by the first control signal;
• and
• supplying, sequentially, the initialization signals and the data signals to the pixel portion via first, second and third data line outputs from each demultiplexer.
