Abstract

See full text

A pixel of a display device is disclosed. According to one aspect, the pixel includes an organic light emitting diode (OLED). The pixel further includes a data sustain unit configured to maintain a data signal input from a data line during light emission of the OLED, a driving current supply unit configured to receive the data signal from the data sustain unit to emit light from the OLED, and a relay transistor configured to insulate the data sustain unit and the driving current supply unit from each other during light emission by the OLED. A data signal input to the data sustain unit is transmitted to the driving current supply unit after the OLED emits the light. A driving speed at which data to display a stereoscopic image is input may be decreased, a luminance reduction by black data may be reduced, and power consumption may be reduced.
