  • Publication number: 20190213958
    Abstract: An organic light-emitting display device includes a display unit having a plurality of pixel units. The display device also includes a timing controller for calculating a black bias pixel ratio (BBPR) of the display unit based on image signals provided by an external source and for generating a control signal based on the BBPR. The BBPR is the ratio of a number of pixel units in a black state to a total number of pixel units. A power supply unit provides a driving voltage to the display unit based on the control signal from the timing controller, wherein the power supply unit provides a first driving voltage to the display unit when the BBPR is less than a reference value and provides a second driving voltage, which is higher than the first driving voltage, otherwise.
