Abstract: A light emitting display apparatus includes a light emitting display panel including a plurality of pixels each operating in order of an initialization period, a sampling period, an offset voltage formation period, a data writing period, and a light emission period; a data driving circuit configured to supply data voltage to each of the pixels; a gate driving circuit configured to provide, to each of the pixels, a control signal having voltage levels determined for the initialization period, the sampling period, the offset voltage formation period, the data writing period, and the light emission period of a corresponding pixel; and a timing controller configured to control the data driving circuit and the gate driving circuit, wherein the offset voltage formation period is longer than the sampling period.
