Patent ID: 11881178
Assignee: LG DISPLAY CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 19:
20. A light emitting display device, comprising:
a display panel including M subpixels sharing a same 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,
wherein the M sub-pixels are initialized based on an initialization voltage during an initial period,
wherein the M sub-pixels are sensed during a sensing period based on a sensing voltage applied during a data writing period,
wherein the initial period is longer than the sensing period for sensing at least one of the M sub-pixels, and precedes both the data writing period and the sensing period,
wherein the data writing period and the sensing period are alternately repeated K times, where K is an integer equal to or greater than 2,
wherein one period in which repeated sensing is performed K times is applied to one sensing line of the display panel, and
wherein periods in which sensing is performed in all sensing lines of the display panel do not overlap with each other.
