Abstract: A liquid crystal display device includes a source device that outputs image data and a sink device that performs a displaying operation based on the image data. The source device changes a frame rate of an image frame composing the image data while the displaying operation is performed. The sink device changes a frame rate of a panel driving frame for the displaying operation by adjusting a vertical blank period of the panel driving frame as the frame rate of the image frame is changed. Here, the sink device adjusts a common voltage applied to a display panel included in the sink device during a display operation of an individual frame, in accordance with the frame rate of the panel driving frame.

Abstract: A display device includes a display panel which includes a plurality of gate lines and a plurality of pixels, where each of the pixels is connected to a corresponding gate line among the gate lines, and a gate driving circuit which includes a stage that applies a gate signal to at least one of the gate lines. The gate signal includes a high period in which the gate signal has a high voltage and a low period in which the gate signal has a low voltage having a level less than a level of the high voltage, and the low period includes a falling period in which the low voltage falls to a second level from a first level which is greater than the second level.
