DRIVING CIRCUIT FOR ORGANIC LIGHT EMITTING DIODE

摘要

A driving circuit for an organic light emitting diode is provided to improve operation reliability of the OLED(Organic Light Emitting Diode) by preventing deterioration of the OLED. A driving circuit for an organic light emitting diode includes a switching portion(41), a driving controller(42), and an OLED(Organic Light Emitting Diode) driver(43). The switching portion receives a data voltage in a frame basis and is charged. The driving controller alternatively drives dual structure driving transistors for every frame by using the voltage, which is outputted from the switching portion. The OLED driver includes a pair of transistors, which alternatively drive OLEDs under the control of the driving controller. The switching portion includes a data transistor and a condenser. The data transistor receives the data voltage according to a scan pulse. The condenser is charged by the voltage inputted from the data transistor.
