Abstract
An organic light emitting display and a driving method thereof, which can effectively detect degradation information of pixels in a display. An organic light emitting display includes a pixel unit and a degradation detector. The pixel unit has a plurality of pixels positioned at intersection portions of scan lines and data lines. The degradation detector divides the pixel unit into a plurality of first blocks each including a plurality of pixels, and detects degradation information for each second block including a plurality of first blocks. In the degradation detector, the second blocks are divided so that each second block shares one or more first blocks with another second block adjacent thereto.
Claims20
An organic light emitting display, comprising:
- a pixel unit having a plurality of pixels positioned at intersection portions of scan lines and data lines;
- and
- a degradation detector dividing the pixel unit into a plurality of first blocks each including a plurality of pixels, and detecting degradation information for a second block that includes a plurality of first blocks, said degradation detector divides the second blocks so that each second block shares one or more first blocks with another second block adjacent thereto.
A driving method of an organic light emitting display, comprising:
- dividing a pixel unit into a plurality of first blocks each including a plurality of pixels;
- generating accumulation data by accumulating data for each first block during a certain period;
- dividing the pixel unit into second blocks each including a plurality of first blocks;
- and
- detecting degradation information for each second block by adding accumulation data of the first blocks included in each second block,
- wherein the second blocks are divided by being sequentially shifted in horizontal and vertical directions, and
- wherein the second blocks are divided so that each second block shares one or more first blocks with another second block adjacent thereto.
An organic light emitting display, comprising:
- a pixel unit having a plurality of pixels positioned at intersection portions of scan lines and data lines;
- and
- a degradation detector dividing the pixel unit into a plurality of first blocks each including a plurality of pixels, and detecting degradation information for a second block that includes a plurality of first blocks, said degradation detector divides the second blocks so that each second block shares one or more first blocks with another second block adjacent thereto,
- wherein the second blocks are divided by being sequentially shifted in horizontal and vertical directions, and
- wherein the second blocks are divided so that each second block shares one or more first blocks with another second block immediately adjacent thereto.
