Abstract: A display device includes: a display panel configured to display an image corresponding to an image signal, and including pads; and a driving chip configured to provide data signals to the pads. The driving chip includes: an analog part configured to convert an input voltage received through an input line into a driving voltage, and convert an image data signal into the data signals; and buffers configured to receive a buffer voltage through a buffer line that is different from the input line, and output the data signals to the pads.

Abstract: A display panel driver includes a timing controller and a data driver. The timing controller generates a data signal based on an input image data. The data driver receives the data signal, converts the data signal into a data voltage and outputs the data voltage to a display panel. The data signal includes positive data and negative data. The data driver includes a data skew compensating circuit which samples the positive data using the negative data and compensates a skew of the data signal.

Abstract: A display device includes: a display panel including gate lines, a data lines crossing the gate lines, and pixels connected to the data lines and the gate lines; a data driver configured to drive the data lines; a gate driver configured to drive the gate lines in synchronization with a vertical sync start signal; and a timing controller configured to control the data driver and the gate driver in response to an image signal and a control signal inputted thereto from an outside, where the timing controller outputs the vertical sync start signal to the gate driver, and changes a frequency of the vertical sync start signal when an image signal of a current frame is identical to an image signal shifted from an image signal of a previous frame in a first direction.
