摘要

PROBLEM TO BE SOLVED: To reduce time required for write operations while maintaining the accuracy of data write accurate.

SOLUTION: A light emitting display equipped with light emitting elements that emit light in accordance with a supplied current is provided with: driving current generating elements (10) which generate a driving current for making light emitting elements (14) emit light; data lines (DL) to which a voltage signal and a current signal corresponding to the data of emitted light quantity in the light emitting elements is successively supplied; and voltage holding elements (C) which are connected to the data line and successively hold charging voltage based on the voltage signal and the current signal corresponding to the data of emitted light quantity. In accordance with the charging voltage based on the current signal held by the voltage holding elements, the driving current generating elements supply the generated driving current to the light emitting elements to generate the accurate driving current corresponding to the data of the emitted light quantity, and reduce the time which is required for data write in the voltage holding elements.
