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

摘要

An organic light-emitting display device displays a grayscale level by time-dividing each frame into N sub-frames, the organic light-emitting display device including: a plurality of pixels arranged in a matrix; a plurality of scan lines to be provided with a plurality of scan signals to turn on the plurality of pixels; and a plurality of data lines to be selectively provided with a plurality of data voltages or a plurality of sensing voltages to be applied to a number of the pixels that are turned on by each of the plurality of scan signals, wherein the scan signals are provided to N scan lines (where N is a natural number greater than 1) that are randomly selected from among the plurality of scan lines at intervals of a sub-horizontal period.

1. An organic light-emitting display device configured to display a grayscale level by time-dividing each frame into N sub-frames, the organic light-emitting display device comprising:
a plurality of pixels arranged in a matrix; a plurality of scan lines configured to be provided with a plurality of scan signals to turn on the plurality of pixels; and a plurality of data lines configured to be selectively provided with a plurality of data voltages or a plurality of sensing voltages to be applied to a number of the pixels that are turned on by each of the plurality of scan signals, wherein the scan signals are provided to N scan lines (where N is a natural number greater than 1) that are randomly selected from among the plurality of scan lines at intervals of a sub-horizontal period, the intervals of the sub-horizontal period being obtained by dividing a unit horizontal period for which a frame is displayed by a number of the plurality of scan lines, and wherein in response to the plurality of the sensing voltages being applied to a first group of pixels coupled to each of the N scan lines selected in a first sub-horizontal period, the first group of pixels are rescanned and provided with the plurality of the data voltages in a second sub-horizontal period that follows the first sub-horizontal period.
