Abstract
A display device can include a display panel including subpixels having light-emitting elements, a data driver configured to supply a data voltage or a park voltage to the subpixels through a data line, and a timing controller configured to control the data driver and provide a park voltage control value to the data driver. The data driver generates the park voltage based on the park voltage control value.
Claims15
A display device comprising:
- a display panel including subpixels, each of the subpixels having a light-emitting element;
- a data driver configured to supply a data voltage or a park voltage to the subpixels through data lines;
- and
- a timing controller configured to control the data driver and provide a park voltage control value to the data driver,
- wherein the data driver generates the park voltage based on the park voltage control value.
2 more elements
A data driver comprising:
- a first digital-to-analog converter configured to generate a park voltage and gamma reference voltages;
- a second digital-to-analog converter configured to generate a data voltage based on the gamma reference voltages;
- and
- a selector configured to selectively output one of the park voltage and the data voltage,
- wherein the first digital-to-analog converter generates the park voltage based on an external park voltage control value.
