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.

Abstract: A display device includes a display panel including a first display region and a second display region surrounding the first display region, where a first pixel having a first size is disposed in the first display region, and a second pixel having a second size is disposed in the second display region, a gate driver which applies a gate signal to a gate line, a data driver which applies a data voltage to a data line, and a timing controller which controls the gate driver and the data driver. The gate line includes a first gate line connected to both the first pixel and the second pixel, and a second gate line connected only to the second pixel. The data line includes a first data line which does not transmit the data voltage to the second pixel connected to the second gate line, and a second data line which transmits the data voltage to the second pixel connected to the second gate line.

Abstract: A display device includes a display panel which defines first and second display areas, and includes pixels connected to data lines and scan lines, respectively, a data driving circuit which drives the data lines, a scan driving circuit which drives the scan lines, and a driving controller which receives an image signal and a control signal, control the data and scan driving circuits according to an operation mode, and output clock signals. In a multi-frequency mode, the scan driving circuit includes a first scan driving circuit corresponding to the first display area and a second scan driving circuit corresponding to the second display area. The second scan driving circuit sequentially drives first scan lines among scan lines corresponding to the second display area during a first frame, and sequentially drives second scan lines among scan lines corresponding to the second display area during a second frame.
