US 2019/0096330 A1 · ORGANIC LIGHT EMITTING DISPLAY DEVICE

Abstract

In an organic light emitting display device which displays an image in a first mode or a second mode, the organic light emitting display device includes: a first scan driver which supplies a first scan signal having a first voltage to first scan lines; a second scan driver which supplies a second scan signal having a second voltage larger than the first voltage to second scan lines; and a pixel unit including pixels each coupled to a corresponding first scan line and a corresponding second scan line. When a first image displayed in the second mode is changed to a second image to be displayed in the second mode, the second image is displayed in the first mode during a predetermined portion of a period, in which the second image is displayed, and is displayed in the second mode during the remaining portion of the period.

An organic light emitting display device which displays an image with a first driving frequency in a first mode or with a second driving frequency lower than the first driving frequency in a second mode, the organic light emitting display device comprising:

a first scan driver which supplies a first scan signal having a first voltage to first scan lines;
a second scan driver which supplies a second scan signal having a second voltage larger than the first voltage to second scan lines;
and
a pixel unit including a plurality of pixels, each coupled to a corresponding first scan line among the first scan lines and a corresponding second scan line among the second scan lines,
wherein, when a first image displayed in the second mode is changed to a second image to be displayed in the second mode, the second image is displayed in the first mode during a predetermined portion of a period in which the second image is displayed, and the second image is displayed in the second mode during the remaining portion of the period.

pixels coupled to first scan lines, second scan lines, and data lines;
a first scan driver which supplies a first scan signal to the first scan lines;
a second scan driver which supplies a second scan signal to the second scan lines;
a timing controller which supplies start pulses of which numbers are equal to each other to the first scan driver and the second scan driver in the first mode, and supply start pulses of which numbers are different from each other to the first scan driver and the second scan driver in the second mode,
wherein, when an image displayed in the second mode is changed to another image to be displayed in a second mode, the another image is displayed in the first mode during a portion of a period in which the another image is displayed, and is displayed in the second mode during the remaining portion of the period.
