Method of driving organic light emitting display
First Claim
1. A method of driving an organic light emitting display, the organic light emitting display having a plurality of data lines for transmitting data signals, a plurality of scan lines for transmitting scan signals, a plurality of emission control lines for transmitting emission control signals, and a plurality of pixels, the method comprising:
- receiving the data signals that enable the plurality of pixels to operate in a normal mode;
determining whether or not the plurality of pixels are receiving an operation signal within a first reference time; and
switching to a standby mode if the operation signal is not received within the first reference time, wherein during the normal mode a display operation by the plurality of pixels is performed in full color, and during the standby mode, the display operation is performed in restricted colors or a duty ratio of the emission control signal is adjusted to reduce pixel luminance.

Abstract
A method of driving an organic light emitting display is provided in which, during a standby mode, a display operation is performed using only eight colors. In the alternative, the luminance of a plurality of pixels is reduced by adjusting a duty ratio of the emission control signals. By reducing the luminance, power consumption and image sticking are reduced, and the life span of the pixels is increased.

8. A method of driving an organic light emitting display having a plurality of data lines for transmitting data signals, a plurality of scan lines for transmitting scan signals, a plurality of emission control lines for transmitting emission control signals, and a plurality of pixels, the method comprising:
-
receiving the data signals such that the plurality of pixels perform a display operation in a normal mode;
determining whether or not the plurality of pixels receive an operation signal within a first reference time;
switching to a standby mode if the operation signal is not received within the first reference time;
determining whether or not the plurality of pixels receive the operation signal within a second reference time; and
turning off the plurality of pixels when the plurality of pixels do not receive the operation signal within the second reference time, wherein during the standby mode the plurality of pixels perform the display operation in a restricted group consisting of eight colors.
