1. A display device, comprising:
a control printed circuit board;
a first source printed circuit board connected to the control printed circuit board through a cable;
a second source printed circuit board connected to the first source printed circuit board through a flexible printed circuit board;
a display panel including a plurality of pixels and connected to the first source printed circuit board and the second source printed circuit board through a connection part; and
a timing controller integrated in the control printed circuit board, and configured to determine predicted power currents based on input image data, to determine a target gain based on the predicted power currents and a maximum allowable power current of the flexible printed circuit board, and to correct the input image data corresponding to a gain reduction region of the display panel based on the target gain,
wherein the maximum allowable power current is a maximum current value that flows in the flexible printed circuit board.
