Abstract
An organic light emitting display includes a brightness controller that restricts the total brightness of a pixel unit when the number of pixels that emit bright light is greater than a predetermined level.
Claims14
An organic light emitting display, comprising:
- a pixel unit comprising a plurality of pixels;
- a scan driver that transmits scan signals and emission control signals to the pixel unit;
- a data driver that converts video data signals to data signals and transmits the data signals to the pixel unit;
- a brightness controller that restricts the brightness of the pixel unit by generating frame data by summing the video data corresponding to one frame and the brightness controller generating brightness control signals to restrict the brightness of the pixel unit based on the magnitude of the frame data;
- and
- an emission controller that controls the emission control signals in response to the II brightness control signals from the brightness controller.
3 more elements
A method of driving an organic light emitting display, comprising:
- generating frame data by summing the video data corresponding to one frame;
- and
- restricting the brightness of a pixel unit when the magnitude of the frame data is greater than a predetermined level and not restricting the brightness of the pixel unit when the magnitude of the frame data is equal to or less than the predetermined level.
