Claims20
A display device, comprising:
- a plurality of data drivers supplying a data signal;
- a display panel comprised of a plurality of pixel regions and a plurality of power lines, the display panel being configured to:
- receive the data signal, and
- display an image based on the data signal, wherein the plurality of power lines are configured to supply a source voltage to the plurality of pixel regions;
- and
- at least one power controller configured to:
- supply the source voltage to the plurality of power lines,
- detect a current flowing through the plurality of power lines, and
- control the source voltage in order to control the source voltage from being supplied to the plurality of power lines based on the detected current.
A method of driving a display device, comprising:
- supplying a source voltage from a plurality of output terminals of at least one power controller to a plurality of pixel regions of a display panel, wherein the source voltage is supplied to the pixel regions via a plurality of power lines;
- supplying a data signal from a plurality of data drivers to the plurality of pixel regions of the display panel;
- displaying an image using the source voltage and the data signal;
- detecting, by the at least one power controller, a current flowing through the plurality of power lines, and
- selectively blocking out the source voltage to the plurality of power lines by the at least one power controller based on the detected current.
An OLED display device, comprising:
- a plurality of data drivers supplying a data signal,
- an OLED display panel comprised of a plurality of pixel regions and a plurality of power lines, the display panel configured to:
- receive the data signal, and
- display an image based on the data signal, wherein the plurality of power lines are configured to supply a source voltage to the plurality of pixel regions;
- at least one power controller configured to:
- supply the source voltage to the plurality of power lines via a pre-power line, wherein each pre-power line supplies the source voltage to a plurality of power lines;
- detect a current flowing through the pre-power lines, and
- control the source voltage according to the detected current.
