Abstract
A light emitting display having an emissive element which emits light in response to a supplied current, comprises a drive current generating element for generating a drive current for allowing light to be emitted from the emissive element, a data line onto which a voltage signal and a current signal corresponding to data regarding an amount of light emission from the emissive element are sequentially supplied, and a voltage storage element connected to the data line and for sequentially storing a charge voltage based on the voltage signal and the current signal corresponding to data regarding the amount of light emission. The drive current generated by the drive current generating element based on a charge voltage corresponding to the current signal stored in the voltage storage element is supplied to the emissive element so that generation of precise drive current corresponding to data regarding the amount of light emission is enabled and the time required for writing data into the voltage storage element is shortened.
