Organic light-emitting display device

A method for operating an organic light-emitting display device,

• the organic light-emitting display device comprising:
• an organic light-emitting panel comprising a plurality of pixel regions, each pixel region comprising a scan line and a data line crossing each other, each pixel region further comprising an organic light-emission element and a drive transistor configured to drive the organic light emission element;
• the method comprising:
• sensing a threshold voltage of the drive transistor in a sensing interval,
• and
• controlling a light emission of the organic light emission element within the pixel region in a display interval.
