Abstract
An organic light emitting display, and a method of driving the same, including a pixel unit having pixels to display images and a brightness controller to restrict the brightness of the pixel unit. The brightness controller generates frame data by summing the video data in one frame so that the brightness of the pixel unit is restricted when the value of the frame data is no less than a predetermined value and so that the brightness of the pixel unit is not restricted when the value of the frame data is no more than a predetermined value.
Claims19
An organic light emitting display, comprising:
- a pixel unit including pixels receiving scan signals, emission control signals, and data signals to display images;
- a brightness controller to restrict brightness of the pixel unit;
- a scan driver to transmit the scan signals and the emission control signals to the pixel unit;
- and
- a data driver to generate the data signals using video data and to transmit the data signals to the pixel unit,
- wherein the brightness controller generates frame data by summing the video data in one frame, and the brightness of the pixel unit is restricted when a magnitude of the frame data is no less than a first value and is not restricted when the magnitude of the frame data is no more than a second value.
An organic light emitting display, comprising:
- a pixel unit including pixels receiving scan signals, emission control signals, and data signals to display images;
- a brightness controller to restrict the brightness of the pixel unit;
- a scan driver to transmit the scan signals and the emission control signals to the pixel unit;
- and
- a data driver to generate the data signals using video data and to transmit the data signals to the pixel unit,
- wherein the brightness controller generates frame data by summing the video data in one frame, and
- wherein brightness restriction of the pixel unit changes with the magnitude of the frame data.
A method of driving an organic light emitting display, comprising:
- summing video data input in one frame;
- and
- restricting brightness of a pixel unit when the magnitude of the summed data is no less than a first level, and not restricting the brightness of the pixel unit when the magnitude of the summed data is no more than a second level.
