ACTIVE-MATRIX DISPLAY

摘要

A display is disclosed which comprises a plurality of scanning lines (Wscan, Escan) which are selected sequentially, a plurality of data lines (Data) to which a write current (Idata) according to luminance information is supplied according to selection of the scanning lines, and a plurality of pixels (PX) arranged on their intersections. Each pixel comprises a light-emitting device (OLED), a drive transistor (TFT4), a capacitor (C) which is connected to the gate (Nd) of the drive transistor and stores write date, a first transistor (TFT1) which conducts during a write period when the scanning line is scanned and connects the date line and the drain of the drive transistor, and a second transistor (TFT2) which conducts during the write period and short-circuits the gate and drain of the drive transistor. This structure enables to drive the light-emitting device with a drive current which is equivalent to the write current without being affected by variations in transistor characteristics.
