Abstract
A light emitting device and a method of driving the same are provided where a cross-talk problem can be overcome. The light emitting device includes a display panel including a plurality of scan lines disposed in a first direction, a plurality of data lines disposed in a second direction, wherein the second direction is different from the first direction, and a plurality of pixels that are defined as overlying areas of the plurality of scan lines and the plurality of data lines, and a cross-talk preventing circuit configured to provide the plurality of scan lines with compensating currents according to display data provided by an outside device.
Claims23
A light emitting device, comprising:
- display panel including:
- a plurality of scan lines disposed in a first direction;
- a plurality of data lines disposed in a second direction, wherein the second direction is different from the first direction;
