Abstract

This paper presents a novel low power driving circuit for passive matrix organic lighting emitting diodes (OLED) displays. The proposed driving method for a low power OLED driving circuit which reduce large parasitic capacitance in OLED panel only use current driving method, instead of mixed mode driving method which uses voltage pre-charge technique. The driving circuit is implemented to one chip using 0.35${\mu}{\textrm}{m}$ CMOS process with 18V high voltage devices and it is applicable to 96(R.G.B)X64, 65K color OLED displays for mobile phone application. The maximum switching power dissipation of driving power dissipation is 5.7mW and it is 4% of that of the conventional driving circuit.
