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 backlight dimming method and a liquid crystal display using the same are disclosed. The backlight dimming method includes producing a first backlight dimming value controlling a backlight luminance of a liquid crystal display panel, producing a convex gain which has less value in a peripheral part of a screen of the liquid crystal display panel than a central part of the screen, reducing the first backlight dimming value to be applied to the peripheral part of the screen using the convex gain to produce a second backlight dimming value, and controlling the backlight luminance of the liquid crystal display panel using the second backlight dimming value.
