An organic light emitting display (OLED) device using a tiling technique including a system-on-panel (SOP)-type emission control driver. The emission control driver includes a shift register and a logical operation portion having a plurality of logic gates, each of which receives output signals from the shift register and performs a logical OR operation on the received signals. An active load of each of the logic gates is controlled using two output signals and two inverted output signals of two adjacent flip-flops. Also, each of the logic gates performs a logical OR operation on the two output signals of the two adjacent flip-flops and generates an emission control signal. The flip-flops and the logic gates of the emission control driver include positive channel metal oxide semiconductors (PMOS) transistors.
