Abstract: A display device includes a display panel including a plurality of pixels and a display panel driver configured to drive the display panel. Here, the display panel driver is configured to receive input image data, to drive the display panel at a first driving frequency when the input image data corresponds to a moving image, and to select one of a plurality of flicker lookup tables based on the first driving frequency and drive the display panel at a second driving frequency based on the flicker lookup table when the input image data corresponds to a still image.

Abstract: A display apparatus includes a display panel, a gate driver, a data driver, a driving controller and a power voltage generator. The display panel displays an image based on input image data. The gate driver outputs a gate signal to a gate line. The data driver outputs a data voltage to a data line. The driving controller drives display areas of the display panel in different driving frequencies. The power voltage generator outputs a data power voltage to the data driver. The driving controller outputs an output data enable signal including a writing period having an active signal and a holding period having an inactive signal for the respective display areas. The power voltage generator generates the data power voltage having a high power voltage level during the writing period and a low power voltage level in at least a portion of the holding period.

Abstract: A display device includes a display panel including a pixel and a driving controller to drive the display panel. The driving controller generates a compensating signal, when a first driving frequency of a first frame is determined as being higher than a second driving frequency of a second frame by comparing a first cycle count value of the first frame with a second cycle count value of the second frame subsequent to the first frame.

Abstract: A display device, which is a slidable display device, includes a display panel and a data driver. The display panel includes a first display area, a second display area that is in one of a taken-in position and a taken-out-of position of the display device, and a pad area located on one side of the first display area. The display panel includes pixels disposed in the first and second display areas, and is driven in a first mode in which an image is displayed in the first display area or a second mode in which an image is displayed in the first and second display areas. The data driver generates data voltages based on pixel data, outputs the data voltages to the pixels, and controls an order of the data voltages output in the second mode.

Abstract: A data driver for providing data voltages to a display panel includes a digital-to-analog converting block, an option storing block, a data swap block and an output buffer block. The digital-to-analog converting block converts line data into the data voltages. The option storing block stores a pixel arrangement option representing a pixel arrangement structure of the display panel. The data swap block is connected to the digital-to-analog converting block and the option storing block, and selectively performs a data swap operation that swaps the data voltages based on the pixel arrangement option and whether the line data are odd line data or even line data. The output buffer block is connected to the data swap block and outputs the data voltages on which the data swap operation is selectively performed to data lines.
