Abstract: An electroluminescence display includes a plurality of sub-pixels, each of the plurality of sub-pixels including a light emission region, and a first circuit region and a second circuit region disposed on respective sides of the light emission region. Power supply lines are configured to supply a first power to at least one of the second circuit regions of the sub-pixels arranged at odd-numbered row and the first circuit regions of the sub-pixels arranged at an even-numbered row. A sensing line is configured to supply an initialization voltage or a sensing voltage to at least one of the first circuit regions of the sub-pixels arranged at the odd-numbered row and the second circuit regions of the sub-pixels arranged in the even-numbered row.

Abstract: The present disclosure relates to an ultra high density display having high aperture ratio. The present disclosure suggests a display comprising: a upper horizontal current line, a horizontal sensing line, a scan line and a lower horizontal current line running in horizontal direction and sequentially disposed in vertical direction on a substrate in this order from the upper side to the lower side; an emission area defined between the horizontal sensing line and the upper horizontal current line; a non-emission area defined between the horizontal sensing line and the lower horizontal current line; a switching thin film transistor and a sensing thin film transistor disposed between the horizontal sensing line and the scan line; a driving thin film transistor disposed between the scan line and the lower horizontal current line; an anode electrode expanded from the emission area to the non-emission area, and connected to the driving thin film transistor; and an anode bottle neck part disposed between the horizontal sensing line and the scan line for disconnecting the anode electrode from the driving thin film transistor selectively.
