| Zusammenfassung: | The embodiments relate to an organic light emitting display panel, an organic light emitting display device, and a method for driving the organic light emitting display device. A voltage boosting time for boosting the voltage of the source node or drain node of a driving transistor to a luminous minimum voltage is reduced by using image information. Thereby, the variation of the voltage boosting time between sub pixels is reduced. So, screen burn-in can be prevented or reduced. The organic light emitting display device includes a data driving part, a gate driving part, and a timing control part.
본 실시예들은, 영상정보를 이용하여, 구동트랜지스터의 소스 노드 또는 드레인 노드의 전압을 발광가능 최소전압까지 상승시키는데 걸리는 전압 상승 시간을 빠르게 해주고, 이를 통해, 서브픽셀 간의 전압 상승 시간 간의 편차를 줄여줌으로써, 화면 얼룩 현상을 방지하거나 줄여주는 유기발광표시패널, 유기발광표시장치 및 그 구동 방법에 관한 것이다. |
