Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 19:
20. A display device comprising:
a power supply generating an initializing voltage and a supply voltage;
a display panel including a pixel;
a timing controller calculating a load of input image data, and generating image data by scaling a first data value in the input image data to a second data value based on the load; and
a data driver generating a data signal based on the second data value of the image data and providing the initializing voltage provided from the power supply to the pixel;
wherein the power supply provides the supply voltage to the display panel through a power line,
wherein the initializing voltage initializes the pixel,
wherein an amount of driving current flowing through the pixel is varied based on a voltage difference between the data signal and the initializing voltage,
wherein the power supply changes a voltage level of the initializing voltage based on a comparison of a first reference current value and a total current flowing from the power supply through the power line to the display panel according to the supply voltage, and
wherein the first reference current value is preset.
