- Abstract
- Provided is a voltage/current driven active matrix organic electroluminescent (EL) pixel circuit. In particular, a voltage/current driven active matrix organic EL pixel circuit capable of driving organic ELs by a voltage programming method and a current programming method using one pixel circuit and an organic EL display device that uses such a pixel circuit are provided. The voltage/current driven active matrix organic EL pixel circuit can be used for a voltage driven active matrix organic EL and a current driven active matrix organic EL by programming such that the flexibility and applicability of the pixel circuit and the driving circuit are excellent.
