Abstract
Disclosed are a driving circuit and driving method for an organic light emitting diode (OLED) device. The driving circuit for the OLED device comprises RGB pixels each including: a gate line arranged in a first direction and a data line and a power supply line arranged in a second direction crossing the first direction; a plurality of switching transistors connected to the region where the gate line and the data line intersect; a capacitor connected to the switching transistors and the power supply line; a driving transistor connected to the capacitor and the power supply line; an OLED connected to the driving thin film transistor; a variable voltage signal connected to one of the plurality of switching transistors; and a driving signal connected to at least one of the switching transistors, wherein the variable voltage signal is independently connected to the RGB pixels, and the transistors are thin film transistors.
