Abstract:
A flat panel display device and a source driver circuit for the flat panel display device are provided for performing multiple driving operations within a unit sourcing period. In the flat panel display device, multiple driving operations are performed within the unit sourcing period, and source voltages are supplied to a selected number of data lines in each driving operation. In this case, one DAC is driven to generate source voltages for a plurality of data lines. In the flat panel display device, the number of the DACs is reduced and the overall layout area is greatly reduced. Also, standby power consumption can be greatly reduced due to the reduced number of amplifiers. Since the source voltages provided by the same amplifier are provided to adjacent data lines, a metal layer can be easily wired in the display panel.
