Abstract
A data driver capable of generating pre-emphasis voltages is provided. The data driver includes a pre-emphasis unit for comparing previous input data signals with current input data signals to generate pre-emphasis data signals, a first register unit for storing the current input data signals from the pre-emphasis unit and for supplying the previous input data signals to the pre-emphasis unit, and a second register unit for storing the pre-emphasis data signals.
Claims12
A data driver, comprising:
- a pre-emphasis unit for comparing previous input data signals with current input data signals to generate pre-emphasis data signals;
- a first register unit for storing the current input data signals from the pre-emphasis unit and for supplying the previous input data signals to the pre-emphasis unit;
- and
- a second register unit for storing the pre-emphasis data signals.

A method of driving a data driver, comprising:
- supplying current input data signals to a first register unit while receiving previous input data signals from the first register unit;
- comparing the current input data signals with the previous input data signals to generate pre-emphasis data signals;
- storing the pre-emphasis data signals in a second register unit;
- generating first output data signals using the pre-emphasis data signals and generating second output data signals using the current input data signals;
- and
- supplying the first output data signals and the second output data signals to data lines at different times.
