ABSTRACT:
A light emitting display for compensating for the threshold voltage of transistor or mobility and fully charging a data line. A transistor and first through third switches are formed on a pixel circuit of an organic EL display. The transistor supplies a driving current for emitting an organic EL element (OLED). The first switch diode-connects the transistor. A first storage unit stores a first voltage corresponding to a threshold voltage of the transistor. A second switch transmits a data current in response to a select signal. A second storage unit stores a second voltage corresponding to the data current. A third switch transmits the driving current to the OLED. A third voltage determined by coupling of the first and second storage units is applied to a transistor to supply the driving current to the OLED.
