8.10 VSYNC Interface

8.10.1 18-bit RGB Interface

The ST7789V2 incorporates VSYNC interface, which enables motion pictures to be displayed with only

the conventional system interface and the frame synchronization signal (VSYNC). This interface requires

minimal changes from the conventional system to display motion pictures.In this interface the internal display

operation is synchronized with VSYNC. Data for display is written to RAM via the system interface with higher

speed than for internal display operation. This method enables tearing-free display of motion pictures with the

conventional interface.
