Abstract: An information handling system includes a host processing system and a Liquid Crystal Display device. The host processing system includes a graphics processing unit (GPU) and the LCD device includes a memory device and a DisplayPort Configuration Data (DPCD) register. The host processing system 1) determines whether the first GPU supports a Dynamic Display Shifting (DDS) mode, 2) when the GPU does not support the DDS mode, provides a first indication to the LCD device that the GPU does not support the DDS mode, and 3) when the GPU supports the DDS mode, provides a second indication to the LCD device that the GPU supports the DDS mode. The LCD device retrieves a Panel Self Refresh (PSR) setting from the memory device and stores the PSR setting to the DPCD register in response to the first indication, and retrieves a DDS setting from the memory and stores the DDS setting to the DPCD register in response to the second indication.

Abstract: A display and a display panel thereof are provided. A driving circuit is formed on one side of the display panel to output an auxiliary scan signal to one terminal of the scan line in the display panel. A gate driver is formed on another side of the display panel to output a scan signal to another terminal of the scan line in the display panel, so that the two ends of a scan line in the display panel simultaneously receive the scan signal and the auxiliary scan signal. Thereby, not only the display quality of the display is improved and the difficult of repairing the display panel is reduced, but also the production yield rate of the display can be effectively increased. Besides, if the gate driver is not used in the display panel, the driving circuit can be simultaneously formed on both sides of the display panel.
