Abstract
A driving circuit of an organic light emitting display includes: a first PMOS transistor turned on in response to a driving signal to transfer a data signal; an OLED (organic light emitting diode) where an amount of light emitted is controlled by a control current; a second PMOS transistor for supplying the control current to the OLED; a third PMOS transistor connected to a node to which the first and second PMOS transistors are connected; a first capacitor connected between the first PMOS transistor and the third PMOS transistor; and a second capacitor connected between the second PMOS transistor and the first PMOS transistor.
