Zusammenfassung:Technology for a display controller is described. The display controller can detect a frame update when the display controller is in a dynamic sleep state. The display controller can wake up from the dynamic sleep state and enter a selective update state at a programmed vertical blanking interrupt (VBI) that precedes an actual VBI. The display controller can perform a scan-out with a display panel during the selective update state. The display controller can return to the dynamic sleep state in a same time frame after the scan-out is completed. The display controller can exclude timing logic to send a VBI at every time frame to the display panel to maintain time synchronization between the display controller and the display panel.
