Abstract
An OLED pixel circuit includes a charging control module (1), a resetting control module (2), and a driving transistor (3). The charging control module (1) is connected to a data signal line and the resetting control module (2). The resetting control module (2) is connected to the driving transistor (3) to reset and compensate the driving transistor (3) to set a control terminal of the driving transistor (3) at a first potential value. The driving transistor (3) is configured to generate a driving current being based on a difference between a potential of a source of the driving transistor and the first potential value, irrespective of a voltage signal at the source of the driving transistor and a threshold voltage of the driving transistor (3).
