    • The display device of the invention comprises a plurality of scanning lines (Wscan and Escan) which are selected successively, a plurality of data lines (Data) to which the writing electric current (Idata) in accordance with brightness information is supplied according to the scanning line selection, and a plurality of pixels (PX) arranged at intersecting points between the scanning lines and the data lines. Each of the pixels comprises a light emitting element (OLED), a driving transistor (TFT4), a capacitor (C) connected to the gate (Nd) of the driving transistor for accumulating writing data, a first transistor (TFT1) which is turned on during writing period in which the scanning lines are scanned and which connects the data lines and the drain of the driving transistor, and a second transistor (TFT2) which is turned on during the writing period and which short-circuits the gate and drain of the driving transistor. With such a structure, the light emitting element can be driven with a driving electric current equivalent to the writing electric current, irrespective of variations in characteristics of the transistors,
    • 本发明的显示装置包括连续选择的多条扫描线(Wscan和Escan),根据扫描提供根据亮度信息提供写入电流(Idata)的多条数据线(Data) 线选择,以及布置在扫描线和数据线之间的交叉点处的多个像素(PX)。 每个像素包括发光元件(OLED),驱动晶体管(TFT4),连接到用于积累写入数据的驱动晶体管的栅极(Nd))的电容器(C),第一晶体管(TFT 1) 在扫描线被扫描并连接驱动晶体管的数据线和漏极的写入周期期间导通,以及在写入周期期间导通的第二晶体管(TFT 2),并且使栅极短路 和驱动晶体管的漏极。 利用这种结构,可以用与写入电流相当的驱动电流来驱动发光元件,而与晶体管的特性的变化无关,
