Abstract
The present disclosure relates to an OLED pixel circuit, a method for driving the same and a display device. The OLED pixel circuit includes: a data writing and compensating circuit configured to make compensation to a threshold voltage of the first driver; the first driver configured to drive the light emitting device after the threshold voltage is compensated; the second driver configured to drive the light emitting device; the light emitting controller connected to the light emitting device and a second signal terminal, and configured to connect the first driver and the second driver to the light emitting device; and the light emitting device emitting light by joint driving of the first driver and the second driver.
