ORGANIC EL DISPLAY AND ACTIVE MATRIX SUBSTRATE |
摘要 |
<p>An active matrix type organic EL display includes: a drive control element (Dr) having a first terminal connected to a first power source terminal (Vdd), a control terminal, and a second terminal for outputting drive current in accordance with the voltage between the first terminal and the control terminal; a capacitor (C) having one of the electrodes connected to the control terminal and capable of maintaining the voltage between the first terminal and the control terminal constant; and an organic EL element (OLED) connected between the second terminal and a second power source terminal (Vss). A switch between the second terminal and the control terminal consists of plurality of switches (Sw1a to Sw1c) connected in series so as to obtain a complete non-conductivity. By making the switch (Sw1a) of the control terminal side non-conductive earlier than the other switches (Sw1b, Sw1c), the potential shift amount caused by the capacity of the switch itself is reduced.</p> |
