DEGRADATION COMPENSATING PIXEL CIRCUIT AND ORGANIC LIGHT EMITTING DIODE DISPLAY DEVICE INCLUDING THE SAME |
摘要 |
A degradation compensating pixel circuit includes: an organic light emitting diode (OLED); a driving circuit including a first capacitor and a first transistor, the first capacitor being configured to be charged in response to a data signal and a scan signal, the first transistor being configured to drive the OLED according to a first voltage between first and second terminals of the first capacitor, the first terminal of the first capacitor being configured to receive a supply voltage, the second terminal of the first capacitor being coupled to a gate terminal of the first transistor; and a degradation compensating circuit coupled to a source terminal of the first transistor and the gate terminal of the first transistor, the degradation compensating circuit being configured to change the first voltage according to a first current of the first transistor. |
