Abstract: A display device includes a driving controller which receives an image signal and a signal including a command for entering a low power mode, or a command for terminating the low power mode, and generates or receives a first synchronization signal and a second synchronization signal, a panel driver which operates in response to a control signal provided from the driving controller, and a display panel which is controlled by the panel driver. The panel driver includes a data driving circuit which provides a data signal to the display panel in synchronization with the first synchronization signal, and the driving controller changes the control signal by counting a clock of the second synchronization signal, when receiving the command for entering the low power mode or the command for terminating the low power mode.

Abstract: A display device includes a display panel and a display panel driver. The display panel driver includes an over-driver which selects an over-driving data from an over-driving pattern which moves to a predetermined direction, generates a reference line based on a first polynomial expression generated based on the over-driving data, and generates an over-driving data lookup table by moving the reference line, a data driver which outputs a data signal generated based on the over-driving data lookup table to the data line of the display panel, and a gate driver which outputs a gate signal to the gate line of the display panel.
