Apply VDD within the LCD operation period. When the backlight turns on before LCD operation or the LCD operation turns off before the backlight turns off, the display may momentarily become white. When the power is off, please keep whole signals (Hsync, Vsync, CLK, DE, and DATA) low level or high impedance.
