Abstract:
An electroluminescent display (EL) where a signal distortion is reduced or prevented by introducing appropriate distortion to a scan waveform to equalize a variation of a kickback voltage. An EL display includes an organic EL panel that includes a plurality of scan lines, a plurality of data lines, and pixel circuits arranged at the intersections between the scan lines and the data lines; and a scan driver that sequentially selects the scan lines to drive a selection signal. A signal delay is introduced on at least one of an input side and an output side of the scan driver, and may be provided by a signal delay device. Alternatively, the signal delay device may be included in the scan driver, either at an input side or an output side of the shift register or the level shifter.
