Abstract

A pixel of a display panel includes a storage capacitor, at least one scan transistor to transfer first and second voltages to ends of the storage capacitor in response to a scan signal, a driving transistor to generate a driving current based on a difference between the first voltage and the second voltage stored in the storage capacitor, at least one emission transistor to selectively provide the driving current to an organic light emitting diode in response to an emission control signal, and the organic light emitting diode to emit light, wherein the first voltage is a sum of a data voltage and a pixel deviation compensation voltage for compensating a threshold voltage deviation between pixels included in the display panel, and wherein the second voltage is a panel deviation compensation voltage for compensating a threshold voltage deviation between display panels manufactured by a same process for the display panel.
