Abstract
The present disclosure relates to a display panel and a display device using the same, and includes a second pixel area in which pixels having a resolution or pixels per inch (PPI) lower than that of a first pixel area are arranged. A data voltage of pixel data to be written to a pixel in the second pixel area is applied to a first gate electrode of a driving element disposed in the second pixel area. A compensation voltage for increasing luminance of the second pixel area is applied to a second gate electrode of the driving element.
Claims20
A display panel comprising:
- a first pixel area in which pixels are arranged;
- and
- a second pixel area in which pixels having a resolution or pixels per inch less than a resolution or pixels per inch of the first pixel area are arranged, wherein
- each of the pixels in the first pixel area includes a first driving element configured to drive a light emitting element, and
- each of the pixels in the second pixel area includes a second driving element configured to drive a light emitting element, wherein
- the second driving element includes a first gate electrode and a second gate electrode,
- a data voltage of pixel data to be written to a pixel of the second pixel area is applied to the first gate electrode of the second driving element, and
- a compensation voltage for increasing luminance of the second pixel area is applied to the second gate electrode of the second driving element.
