Abstract:
1. A pixel structure of an organic light emitting display device, comprising a first to a fifth thin film transistors, a capacitor and an organic light emitting display device, wherein a drain of the first thin film transistor is connected to a negative supply of a backboard via the organic light emitting display device, a source of the first thin film transistor is connected to a drain of the third thin film transistor, and a source of the third thin film transistor is connected to a positive power supply of the backboard; one end of the capacitor is connected between the first thin film transistor and third thin film transistor, and the other end of the capacitor is connected to a source of the second thin film transistor and a source of the fourth thin film transistor; a drain of the second thin film transistor is connected to a drain of the first thin film transistor and the organic light emitting display device; a drain of the fourth thin film transistor is connected to a drain of the fifth thin film transistor and a gate of the first thin film transistor, a source of the fifth thin film transistor is connected to a data line, and a gate of the fifth thin film transistor and a gate of the second thin film transistor are connected to a scan line; and a first control signal (EM) is provided to a gate of the third thin film transistor, and a second control signal (EMD) is provided to a gate of the fourth thin film transistor.
