Abstract
The embodiments relate to a display device including: a display panel on which multiple pixels are arranged; a first driver IC controlling driving of the pixels arranged in a first area of the display panel, and including a first gamma generator outputting multiple first gamma voltages; and a second driver IC controlling driving of the pixels arranged in a second area of the display panel, and including a second gamma generator outputting multiple second gamma voltages, wherein the first gamma generator and the second gamma generator generate the first gamma voltages and the second gamma voltages, respectively, by using multiple gamma reference voltages output from the first gamma generator.

A display device comprising:
- a display panel on which multiple pixels are arranged;
- a first driver integrated circuit (IC) controlling driving of first pixels from the multiple pixels arranged in a first area of the display panel, and including a first gamma generator that outputs multiple gamma voltages;
- and
- a second driver IC controlling driving of second pixels from the multiple pixels arranged in a second area of the display panel, and including a second gamma generator that outputs the multiple gamma voltages,
- wherein each of the first gamma generator and the second gamma generator generates the multiple gamma voltages by using multiple gamma reference voltages output from the first gamma generator.
A display device comprising:
- a first gamma voltage generator generating multiple first gamma reference voltages from first driving power, and generating multiple first gamma voltages that correspond to multiple grayscales, respectively, by dividing the multiple first gamma reference voltages;
- and
- a second gamma voltage generator generating multiple second gamma voltages by using the multiple first gamma reference voltages generated from the first gamma voltage generator.
