    摘要: A flat panel display device including: a display region including pixels connected to scan lines and data lines; a dummy display region including dummy pixels connected to at least two dummy scan lines and the data lines; a scan driver for providing scan signals and dummy scan signals to the scan lines and the dummy scan lines; a data driver for generating gray scale voltages corresponding to input digital data and providing them to corresponding pixels through the data lines; and a timing controller for controlling the scan driver and the data driver, wherein the data driver uses parasitic capacitance components existing in at least two data lines and capacitance components in the pixels and the dummy pixels connected to the at least two data lines, as a sampling capacitor and a holding capacitor to generate the gray scale voltages through charge sharing between the at least two data lines.

    摘要: A data driver and a method of driving the same. The data driver includes a shift register for generating sampling signals; sampling latches for sampling digital data applied to output channels, respectively, in accordance with the sampling signals; holding latch units for receiving the sampled digital data of the channels from the sampling latches to hold the digital data for a first period; first digital-to-analog converters for receiving the held digital data of the channels from the holding latch units to generate currents corresponding to the digital data; a second digital-to-analog converter commonly connected to the channels and the first digital-to-analog converters to receive the digital data provided from the holding latch units for a second period and to generate correction currents for the data currents; and output stages for sampling, correcting, and driving final currents using the data currents and the correction currents.
