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.

A light emitting display device, comprising:
- a display panel including M subpixels sharing a single sensing line, wherein M is an integer equal to or greater than 2;
- and
- a circuit for sensing elements included in at least one of the M subpixels through the sensing line,
- wherein a first subpixel from among the M subpixels is defined as a sensing subpixel, a second subpixel among the M subpixels is defined as a non-sensing subpixel, and the second subpixel has 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.
A method of driving a light emitting display device, the method comprising:
- applying an initialization voltage for initializing an organic light-emitting diode (OLED) included in a non-sensing subpixel from among M subpixels in an initial period, where M is an integer equal to or greater than 2;
- applying a sensing voltage for sensing an OLED included in a sensing subpixel from among the M subpixels in a data writing period;
- floating an anode electrode of the OLED included in the sensing subpixel in a boosting period;
- and
- sensing the OLED included in the sensing subpixel in a sensing period,
- wherein the initial period is longer than the data writing period.
