Abstract
Circuits for controlling a data driver of a display device are provided. The circuit may include a bias block that may output a first or second bias current or voltage to the data driver and a control unit that may control the bias block to output the first or second bias current or voltage based on a control signal.
Claims20
A circuit for controlling a data driver of a display device, the circuit comprising:
- a bias block configured to provide a bias power to the data driver;
- and
- a control unit configured to control the bias block to selectively output one of a first bias power and a second bias power, which have different magnitudes, to the data driver based on a control signal input to the control unit,
- wherein the bias block provides the first bias power or the second bias power to the data driver according to control of the control unit.
1 more element
A display device, comprising:
- a panel including a plurality of pixels arranged in a matrix form;
- a timing controller configured to output a plurality of control signals;
- a data driver configured to output data signals to data lines connected to the plurality of pixels based on one of the plurality of control signals output from the timing controller;
- and
- a control circuit configured to selectively provide one of a first bias power and a second bias power, which have different magnitudes, to the data driver based on one of the plurality of control signals.
2 more elements
A circuit for controlling a data driver of a display device including a panel including a plurality of pixels, the circuit comprising:
- a biasing block configured to supply one of a plurality of different biasing powers to the data driver,
- a selector configured to select one of the plurality of different biasing powers, wherein the plurality of biasing powers include a first biasing power and a second biasing power, the first biasing power being greater than the second biasing power, and the selector is configured to select the first biasing power to be supplied to the data driver when an operation having an increased slew rate is being performed.
