Abstract
An organic light emitting display and a driving method thereof that reduces false contour noise and the occurrence of a stripe pattern generated in a digital driving manner. The organic light emitting display includes a scan driver for supplying a scan signal to scan lines, a data driver for supplying a data signal to data lines, and pixels coupled to the scan lines and the data lines. Each of the pixels includes an organic light emitting diode. The organic light emitting diodes of the pixels coupled to a scan line are alternately positioned in a first horizontal line and a second horizontal line adjacent to the first horizontal line, respectively.
Claims14
An organic light emitting display comprising:
- a scan driver for supplying a scan signal to scan lines;
- a data driver for supplying a data signal to data lines;
- and
- pixels coupled to the scan lines and the data lines, each of the pixels having a corresponding one of organic light emitting diodes (OLEDs),
- wherein the OLEDs of first pixels and second pixels of said pixels coupled to a first scan line of the scan lines are alternately positioned in a first horizontal line and a second horizontal line adjacent to the first horizontal line, respectively, and third pixels of said pixels coupled to a second scan line of the scan lines are positioned in the first horizontal line, and
- wherein both the first horizontal line and the second horizontal line are located at a same side of the first scan line.
A method of driving an organic light emitting display having pixels coupled to data lines and scan lines, each of the pixels having an organic light emitting diode, the method comprising:
- while supplying a first scan signal to a first scan line of the scan lines, supplying a first data signal to first pixels of the pixels that are coupled to the first scan line and have their organic light emitting diodes (OLEDs) positioned on a first horizontal line;
- while supplying the first scan signal to the first scan line, supplying second data signal to second pixels of the pixels that are coupled to the first scan line and have their OLEDs positioned on a second horizontal line adjacent to the first horizontal line, both the first horizontal line and the second horizontal line being located at a same side of the first scan line;
- and
- while supplying a second scan signal to a second scan line of the scan lines, supplying a third data signal to third pixels of the pixels that are coupled to the second scan line and have their OLEDs positioned in the first horizontal line.
A method of driving an organic light emitting display having a plurality of pixels coupled to scan lines and data lines, the method comprising:
- supplying a first scan signal to a first scan line of the scan lines coupled to first and second pixels of the pixels;
- supplying a first data signal to first pixels of the pixels, each of the first pixels having at least one first organic light emitting diode (OLED) positioned on a first horizontal line;
- supplying a second data signal to second pixels of the pixels, each of the second pixels having at least one second OLED positioned on a second horizontal line adjacent to the first horizontal line, both the first horizontal line and the second horizontal line being located at a same side of the scan line;
- and
- supplying a third data signal to third pixels of the pixels coupled to a second scan line, each of the third pixels having at least one third OLED positioned on the first horizontal line.
