Abstract
A display device includes: a display panel including pixels emitting light, based on a data voltage; a current limiter for determining a scale factor by comparing a previous frame load with a predetermined threshold load, and generating compensated image data by applying the scale factor to current image data as input image data of a current frame to adjust the data voltage; and a data driver for converting the compensated image data into the data voltage and providing the data voltage to the display panel.
Claims20
A display device comprising:
- a display panel including pixels configured to emit light based on a data voltage;
- a current limiter configured to determine a scale factor by comparing a previous frame load with a predetermined threshold load, and generate compensated image data by applying the scale factor to current image data as input image data of a current frame to adjust the data voltage;
- and
- a data driver configured to convert the compensated image data into the data voltage and provide the data voltage to the display panel.
A method of driving a display device, the method comprising:
- comparing a previous frame load with a predetermined threshold load;
- activating a first control signal and a second control signal, when the previous frame load is smaller than the threshold load;
- generating a first scale factor by applying a compensation coefficient to a load scale factor corresponding to the previous frame load, based on the first control signal;
- generating a time weight, based on the activation of the second control signal;
- outputting a current scale factor by applying the time weight to the first scale factor;
- and
- providing a data voltage to a display panel by applying the current scale factor to current image data.
