Abstract
A display device is capable of improving the image quality, the display device including: a display panel; a pixel on the display panel and including at least one light emitting element; a timing controller configured to receive an image data signal of the pixel and to compensate for a gray value of the image data signal based on the number of light emitting elements of the pixel to generate a compensated image data signal; and a data driver configured to select a compensation data signal corresponding to the compensated image data signal from the timing controller and to apply the compensation data signal to the pixel.
Claims20
A display device comprising:
- a display panel;
- a pixel on the display panel, the pixel comprising at least one light emitting element;
- a timing controller configured to receive an image data signal of the pixel and to compensate for a gray value of the image data signal based on the number of light emitting elements of the pixel to generate a compensated image data signal;
- and
- a data driver configured to select a compensation data signal corresponding to the compensated image data signal from the timing controller and to apply the compensation data signal to the pixel.
A display device comprising:
- a display panel comprising a pixel connected to a first driving power line, a second driving power line, a data line, and a first compensation line;
- and
- a driving circuit configured to generate a first compensation voltage based on the number of light emitting elements of the pixel, and to apply the first compensation voltage to the first compensation line,
- wherein the pixel comprises:
- a driving switching element configured to receive a data signal from the data line;
- at least one light emitting element connected to the driving switching element;
- and
- a first compensation switching element comprising a gate electrode connected to the first compensation line, the first compensation switching element being connected between the first driving power line and the driving switching element.
