Organic light emitting display device and driving method thereof

摘要

A driving method of an organic light emitting display device includes: classifying a plurality of luminance steps into at least a low luminance section and a high luminance section; and setting a reference luminance at a predefined level during the low luminance section and adjusting an off duty according to predetermined criteria for each step in the low luminance section.

主权项

1. An organic light emitting display device including a range of brightness of the display device divided into at least a high brightness section and a low brightness section, each section has a plurality of brightness steps, and receiving a user request for adjusting of the brightness of the display device, comprising:
a display unit having a plurality of pixels are arranged in the form of a matrix, wherein the pixels have organic light emitting diodes for emitting light corresponding to a flow of a driving current received thereon; and a driving unit which sets at least one of an off duty and a reference luminance and drives the display unit according to the user request for adjusting of the brightness of the display device, wherein the driving unit maintains a same reference luminance and adjusts preset amount of off duty when the brightness of the display device is adjusted in the low brightness section according to the user request, and the driving unit maintains a same off duty and adjusts preset amount of reference luminance when the brightness of the display device is adjusted in the high brightness section according to the user request.
