In Table 6 below, the backlight current and power are referenced to maximum luminance, 25 °C ambient temperature. Table 6.

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, keep whole signals (Hsync, Vsync, CLK, DE, and DATA) low level or high impedance.

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.
