Abstract: A light emitting display device can include a display panel including M subpixels sharing a sensing line, wherein M is an integer equal to or greater than 2; and a circuit configured to sense one or more elements included in at least one of the M subpixels through the sensing line, in which the M sub-pixels are initialized based on an initialization voltage during an initial period, the M sub-pixels are sensed based on a sensing voltage during a data writing period, and an amount of time of the initial period is longer than an amount of time of the data writing period.

Abstract: An embodiment of the present invention provides a light emitting display device including a display panel including M (M being an integer equal to or greater than 2) subpixels sharing a single sensing line, and a circuit for sensing elements included in at least one of the M subpixels through the sensing line. A first subpixel from among the M subpixels can be defined as a sensing subpixel, a second subpixel can be defined as a non-sensing subpixel. The second subpixel can have an initial period for applying an initialization voltage for a time longer than a data writing period for applying a sensing voltage to the first subpixel.
