Abstract
Disclosed are a data driver, a display, and a method of driving a display. The data driver for driving a data line which is a capacitive load having one end electrically connected to a unit pixel includes an energy retrieving unit configured to drive the data line by applying a voltage to the data line, and a data driving unit configured to finely tune a voltage and drive the data line with an end voltage. The energy retrieving unit retrieves energy charged up in the data line in stages by driving the data line with voltages from a start voltage to the end voltage through an intermediate voltage.
Claims26
A data driver for driving a data line which is a capacitive load having one end electrically connected to a unit pixel, the data driver comprising:
- an energy retrieving unit configured to drive the data line with at least one intermediate voltage by applying the at least one intermediate voltage to the data line;
- and
- a data driving unit configured to finely tune a voltage and drive the data line with an end voltage,
- wherein the energy retrieving unit retrieves energy charged up in the data line in stages by driving the data line with voltages from a start voltage to the end voltage through the at least one intermediate voltage.
A display comprising:
- a display panel in which unit pixels driven by data lines and scan lines are disposed in an array;
- a scan driver configured to drive the scan lines and the unit pixels connected to the scan lines;
- and
- a data driver configured to drive the data lines and the unit pixels connected to the data lines,
- wherein the data driver drives the data lines by providing electrical signals in stages to the data lines which are capacitive loads, and retrieves energy from the data lines in stages.
A method of driving a display, the method comprising:
- providing energy to a data line which is a capacitive load in a form of an electrical signal to drive the data line with a start voltage;
- and
- driving the data line with voltages from the start voltage to an end voltage through an intermediate voltage and retrieving energy charged up in the data line.
