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

Claim 17:
18. A light emitting display device, comprising:
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,
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 an amount of time of the initial period is longer than an amount of time of the data writing period,
wherein the initial period is longer than the sensing period for sensing at least one of the M sub-pixels,
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 a first sensing operation in which repeated sensing is performed K times is performed on a first sensing line for a first time, where K is an integer equal to or greater than 2, and
wherein a second sensing operation for a second sensing line is performed for a second time different from the first time.
