Abstract
Embodiments relate to a display device including pixels that compensate a threshold voltage of a driving transistor using the body effect. Pixel data for the driving transistor increases the source-bulk voltage of the driving transistor during a compensation period as a result of the body effect. A separate reference voltage is not received at the pixel for the purpose of compensating the threshold voltage of the driving transistor. The increased source-bulk voltage is then used in an emission period of the pixel to compensate for the threshold voltage of the driving transistor.
