Classification: CPC G  H | IPC G  H

Claim 10:
11. A method of driving a light emitting display device, the method comprising:
applying an initialization voltage during an initial period for initializing an organic light-emitting diode (OLED) included in at least one subpixel among M subpixels, wherein the M subpixels are connected to a same sensing line and M is an integer equal to or greater than 2;
applying a sensing voltage for sensing an OLED included in a subpixel to be sensed from among the M subpixels in a data writing period;
floating an anode electrode of the OLED included in the subpixel in a boosting period; and
sensing the OLED included in the subpixel in a sensing period,
wherein each of the M subpixels includes a switching transistor and a sensing transistor commonly connected to one scan line,
wherein in one of the M pixels the switching transistor and the sensing transistor are simultaneously turned on in response to a scan signal, and
wherein in the one of the M pixels, an amount of turn-on time of the switching transistor and the sensing transistor during the initial period is longer than an amount of turn-on time of the switching transistor and the sensing transistor during the data writing period.
