Display device and method of driving the same

A display device comprising:

• a display panel including a plurality of pixels;
• a timing controller configured to generate output control information based on an output timing of image data to be written to the plurality of pixels;
• and
• a plurality of amplifiers configured to output a target data voltage corresponding to the image data to output channels connected to the plurality of pixels,
• wherein each of the plurality of amplifiers comprises:
• one or more transistors configured to apply a preset rising current or a preset falling current to an output node connected to one of the channels to output the target data voltage;
• and
• a compensation capacitance adjuster configured to adjust a compensation capacitance of the output node according to the output control information,
• wherein the compensation capacitance adjuster decreases the compensation capacitance of the output node of the amplifier in an initial operation period, and increases the compensation capacitance in an operation period in which the target data voltage is output after the initial operation period,
• wherein the one or more transistors comprise a pull-up transistor and a pull-down transistor, and
• wherein the compensation capacitance adjuster comprises:
• a plurality of capacitors connected in parallel between the output node and a common node of a gate electrode of the pull-up transistor and a gate electrode of the pull-down transistor;
• and
• a switch unit including a plurality of switches connected between the common node and one end of the plurality of capacitors and configured to selectively switch the plurality of capacitors according to the output control information.
