Organic light emitting diode display device and method of driving the same

摘要

Artifacts in a specific pattern due to a time difference in a VTDC driving scheme may be prevented. A display device includes: a display including a first pixel circuit, a second pixel circuit, and a pixel group having a first light emitting element, a second light emitting element, a third light emitting element and a fourth light emitting element arranged in a first direction; and a light emission driver generating a first sub-light-emission control signal for controlling emission of the first light emitting element and a second sub-light-emission control signal for controlling emission of the second light emitting element in a first subframe, and generating a third sub-light-emission control signal for controlling emission of the third light emitting element and a fourth sub-light-emission control signal for controlling emission of the fourth light emitting element in a second subframe.
