Abstract: A display system includes a graphic processor and a display apparatus. The graphic processor supplies a first image signal and a first synchronization signal. The display apparatus is driven in a normal mode in which a first image is displayed, during a first period, based on the first image signal and the first synchronization signal provided from the graphic processor and in a panel self refresh (PSR) mode in which a second image is displayed based on a second image signal stored in a frame buffer of the display apparatus and a second synchronization signal generated in the display apparatus, and transmits the second synchronization signal of the PSR mode to the graphic processor when a driving mode of the display apparatus is changed from the PSR mode to the normal mode. The graphic processor is configured to generate the first synchronization signal synchronized with the second synchronization signal.

Abstract: A display apparatus includes a display panel. The display panel includes a high sub-pixel, a low sub-pixel and a toggle voltage input circuit. The high sub-pixel may include a first switching element connected to a gate line extending in a first direction and a data line extending in a second direction crossing with the first direction. The low sub-pixel may include a second switching element connected to the gate line and the data line and disposed opposite to the high sub-pixel with reference to the gate line, and a third switching element connected to the second switching element and a storage line. The toggle voltage input circuit may be connected to the storage line to transmit a toggle voltage to the low sub-pixel. The toggle voltage may be capable of being varied periodically.
