Abstract
An active matrix display may include: a panel including a plurality of scan lines which transmit scan signals, a plurality of data lines which transmit data signals in response to the scan signals from the scan lines, a plurality of pixel circuits which are formed in a plurality of pixels, and each of the pixel circuits include a display element and a driving transistor driving the display element, and a power line which supplies a driving current to the driving transistor; a scan driver selectively transmitting the scan signals to the scan lines; a compensation circuit unit generating a compensation signal for compensating a voltage drop of the power line which results from a change in a total driving current flowing through the panel; and a data driver compensating the data signals using the compensation signal and transmitting compensated data signals to the data lines.
