Abstract: A display device includes a display panel including first pixels arranged in a first row and second pixels arranged in a second row. A viewing angle of the first pixels is different from a viewing angle of the second pixels. The first pixels and the second pixels are disposed in a privacy region of the display panel and a public region of the display panel which is different from the privacy region. The display device further includes a panel driver configured to receive privacy region position information indicating a position of the privacy region, and drive the display panel such that the first pixels emit light in the privacy region of the display panel and the second pixels emit light in the public region of the display panel.

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 panel driving apparatus includes a data processor configured to receive N-th line data of image data. N is a natural number not less than 2. The data processor is further configured to perform a first line delay on the N-th line data to output (N−1)-th line data, to output (N−1)-th line substitution data which is obtained by N-th line substitution data, which is based on the N-th line data and the (N−1)-th line data, and to compensate the N-th line data based on the N-th line data and the (N−1)-th line substitution data to output compensation image data. The display panel driving apparatus further includes a data driver and a gate driver.

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.

Abstract: A display apparatus includes a display panel, a gate driving part, and a data driving part. The display panel is configured to display an image, and includes a gate line and a data line. The gate driving part is configured to output a gate signal to the gate line. The data driving part is configured to output a data signal to the data line. A transition time of the data signal is a time when the data signal transitions from a low level to a high level, and the transition time of the data signal increases according to a decrease of a load of the display panel.
