Abstract
The present disclosure provides a light emitting display device including a display panel configured to display an image, a data driver configured to drive the display panel, and a timing controller configured to control the data driver, wherein the display panel includes a first sub-pixel connected to a data line but not a sensing line, and a second sub-pixel connected to the data line and the sensing line.
Claims20
A light emitting display device comprising:
- a display panel configured to display an image, the display panel including a data line and a sensing line;
- a data driver configured to drive the display panel;
- and
- a timing controller configured to control the data driver,
- wherein the display panel includes a first sub-pixel connected to the data line without being connected to the sensing line, and a second sub-pixel connected to the sensing line and to the data line that is connected to the first sub-pixel.
A method of driving a light emitting display device including a display panel including a data line, a sensing line, a first sub-pixel connected to the data line but not the sensing line, and a second sub-pixel connected to the data line and the sensing line, the method comprising:
- obtaining a sensed value of the second sub-pixel through the sensing line connected to the second sub-pixel;
- and
- compensating at least one of the first sub-pixel included in the display panel and a device that is required to drive the display panel based on the sensed value of the second sub-pixel.
A light emitting display device comprising:
- a display panel configured to display an image, the display panel including a data line, a sensing line, a first sub-pixel connected to the data line without being connected to the sensing line, and a second sub-pixel connected to the data line and the sensing line;
- a data driver configured to drive the display panel;
- and
- a timing controller configured to generate a compensation value corresponding to the first sub-pixel based on a sensed value of the second sub-pixel sensed through the sensing line,
- wherein the data driver outputs a data voltage that is compensated with the compensation value to the first sub-pixel via the data line.
