Claim:
1. An organic light emitting display comprising: a display panel including sharing pixel groups each including at least one unit pixel; a gate driving circuit configured to generate sensing signals for initializing the unit pixels; and a data driving circuit configured to generate an initialization voltage to be applied to the unit pixels and output the initialization voltage through a plurality of initialization voltage supply channels, wherein when the sensing signals each having a pulse width of N horizontal periods (where N is a positive integer equal to or greater than 2) are shifted based on a line sequential manner while overlapping each other by (N−1) horizontal period, N initialization voltage supply channels are assigned to a plurality of vertically adjacent sharing pixel groups, and wherein N sharing pixel groups which are driven to overlap each other in response to the sensing signals among the plurality of vertically adjacent sharing pixel groups, are connected to different initialization voltage supply channels.
