Abstract
Disclosed are an electroluminescent display and a driving method thereof, the method comprising: generating a predicted value, indicating a degree of degradation of pixels, by accumulating pixel data of an input image at each pixel: and generating a compensation value by adjusting the predicted value to a current measurement value which is obtained by measuring a current in a power line connected to the pixels. Compensation data, which is to be written into each of the pixels, is generated by modulating the pixel data with the compensation value.
Claims17
An electroluminescent display comprising:
- a display panel having a plurality of data lines and a plurality of scan lines intersecting with each other, and a plurality of pixels arranged thereon;
- a compensation device configured to generate a predicted value indicating a degree of degradation of pixels by accumulating pixel data of an input image at each pixel, generate a compensation value by adjusting the predicted value to a current measurement value obtained by measuring a current in a power line connected to the plurality of pixels, and generate compensation data by modulating the pixel data with the compensation value;
- and
- a display panel driving circuit configured to write the compensation data into the plurality of pixels.
A driving method of an electroluminescent display, the method comprising:
- generating a predicted value indicative of a degree of degradation of a plurality of pixels, by accumulating pixel data of an input image at each pixel;
- generating a compensation value by adjusting the predicted value to a current measurement value measured by measuring a current in a power line connected to the plurality of pixels;
- generating compensation data by modulating the pixel data with the compensation value;
- and
- writing the compensation data into each pixel of the display panel.
An electroluminescent display comprising:
- a display panel having a plurality of data lines and a plurality of scan lines intersecting with each other, and a plurality of pixels arranged thereon, wherein sensing lines are not connected to the a plurality of pixels;
- a compensation device configured to:
- generate a predicted value, indicating a degree of degradation of pixels, by accumulating pixel data of an input image at each pixel,
- generate a compensation value by adjusting the predicted value to a current measurement obtained by measuring a current in a power line connected to the pixels, and
- generate compensation data by modulating the pixel data with the compensation value;
- and
- a display panel driving circuit configured to write the compensation data at each pixel.
