Microplasma Current Switch and Its Characteristics

A microplasma current switch (MPCS) for a device operated in a current-mode-like organic light-emitting diodes, which features matrix addressability and current switching, is presented, as well as its architecture and operational principle. The MPCS utilizes the intrinsic memory and conductivity of plasmas to achieve matrix addressability and current switching. We have fabricated a 100 mm ?? 100 mm MPCS panel with a cell pitch of 1080 ??m ?? 1080 ??m. Matrix addressability and current switching are verified. Moreover, the current-voltage curve of the unit cell is measured and analyzed. It exhibits the characteristic of a floating-double-probe diagnosing plasma parameters, so that we estimate the plasma density and electron temperature from it.
