Patent ID: 8604705

Claim:
A compensation circuit of an organic light emitting diode, comprising: a first capacitor having an end being a first node, and another end being a second node; a second capacitor coupled to a first power supply and the first node; a stabilizer unit coupled to the first power supply, a second power supply, a first control signal and a second control signal, and the stabilizer unit including a first transistor, a second transistor and a photodiode, and the first transistor being coupled to the second transistor with a joint thereof being the first node, and the second transistor being coupled to the photodiode; a third transistor coupled to the first node, a data voltage and a third control signal; an organic light emitting diode coupled to the first power supply or the second power supply; and a driver unit coupled to the first power supply or the second power supply, the second node, the organic light emitting diode, the second control signal and a fourth control signal, and the driver unit including a fourth transistor, a fifth transistor and a sixth transistor, and an end of the fourth transistor being coupled to an end of the fifth transistor with a joint thereof being the second node, and another end of the fourth transistor being coupled to another end of the fifth transistor and the sixth transistor.
