Abstract:
1. An OLED apparatus comprising: a first transistor having a first end and a second end, and a first control electrode; an organic light emitting diode having a first electrode and a second electrode; a second transistor having a third end directly connected to the first end of the first transistor and a fourth end directly connected to the first electrode of the organic light emitting diode; a third transistor having a fifth end directly connected to the first electrode of the organic light emitting diode and a sixth end directly connected to a first power supply line, wherein the first power supply line is different from a data line; a fourth transistor having a seventh end directly connected to the first control electrode of the first transistor and a eighth end directly connected to the first end of the first transistor; a capacitive device which has a third electrode directly connected to the first control electrode of the first transistor and a fourth electrode; and a fifth transistor having a ninth end directly connected to the fourth electrode of the capacitive device and a tenth end directly connected to the data line, wherein the eighth end of the fourth transistor is connected to the fifth end of the third transistor through the second transistor; and wherein the third transistor is continuously turned on during an initialization period, a compensation period, a writing period and a discharge period, but is turned off during a light emission period.
