Abstract: A display device, a driving controller, and a driving method provide a fail-safe function. The operating states of driving-related circuits are monitored, and depending on the result of the monitoring, abnormal driving is rapidly and accurately normalized. The performance of display driving and the quality of displayed images are improved.

Abstract: An organic light emitting display device which improves expression capability in a low luminance level region, wherein, when receiving a pulse width modulation value indicating a low luminance level region, the device changes the received pulse width modulation value into a pulse width modulation dimming value indicating a high luminance level region, and expresses a low luminance level region through a luminance level indicated by the pulse width modulation dimming value and a pulse width modulation dimming operation. Luminance in a low luminance level region is controlled through a pulse width modulation dimming value indicating a high luminance level region and a pulse width modulation dimming operation, so that it is possible to minutely control luminance in a low luminance level region and improve expression capability in a low luminance level region.
