发明名称 CURRENT DRIVE CIRCUIT AND DISPLAY COMPRISING THE SAME, PIXEL CIRCUIT, AND DRIVE METHOD
摘要 A display including a current drive circuit capable of supplying a desired current to a light-emitting element in each pixel stably and accurately irrespective of the characteristic variations of active elements in the pixel, thereby providing a high-definition image. Each pixel is composed of a receiving transistor (TFT3) for receiving a signal current (Iw) from a data line (data) when a scanning line (scanA) is selected, a converting transistor (TFT1) for converting the current level of the received signal current (Iw) to a voltage level and holding the voltage level, and a driving transistor (TFT3) for allowing a drive current having a current level corresponding to the held voltage level to flow through light-emitting element (OLED). The converting thin film transistor (TFT1) generates the converted voltage level at its gate by allowing the signal current (Iw) through its channel, and a capacitor (C) holds the voltage level at the gate of the transistor (TFT1). The transistor (TFT2) allows the drive current having a current level corresponding to the voltage level held by the capacitor (C) to flow through the light-emitting element (OLED).
