DISPLAY SYSTEM AND A METHOD OF DRIVING THE DISPLAY SYSTEM INCLUDING A DISPLAY APPARATUS

摘要

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.

1. A display system comprising:
a graphic processor configured to supply a first image signal and a first synchronization signal; and a display apparatus configured to: be 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; to be driven 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 to transmit 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, wherein the graphic processor is configured to generate the first synchronization signal in synchronous with the second synchronization signal.
