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.

Abstract: A method of compressing data comprising separating a bit stream of compensation data into a sub-bit stream including an impulse component and a sub-bit stream not including the impulse component, predicting and calculating a trend component of compensation data to be compressed using compressed compensation data, generating a noise component by eliminating the trend component from the compensation data, and separating and compressing an impulse component and a noise component of the compensation data from each other, wherein the impulse component is compressed without quantization and the noise component is quantized and compressed.
