The present disclosure relates to an organic light emitting diode display having high luminescence. The present disclosure suggests an organic light emitting diode display comprising: a data line, a scan line and a driving current line defining a pixel area on a substrate; an anode electrode formed within the pixel area; an additional capacitance formed by overlapping expanded portions of the anode electrode with some portions of the driving current line; a bank defining a light emitting area in the anode electrode; an organic emission layer formed on the anode electrode; and a cathode electrode formed on the organic emission layer. The present disclosure suggests high luminescence organic light emitting diode display by including an additional capacitance for increasing the anode capacitance.

Organic light emitting diode display having high luminescence

A compensation margin control device, an organic light emitting display device, and a driving method thereof according to the present disclosure provide an effect to improve the image quality by ensuring a margin of a negative bios shift compensation region of a driving transistor of a non-driven sub-pixel without affecting a gray level representation and positive compensation.
