Notes 1. When POWC is “L” logic input signal is all “0 V”. If input more than “0.3 V”, inside circuits of the LCD

module may be broken.
The frame ground, signal ground (GND) and backlight ground (GNDB) are not connected in the LCD
module.
The power supply (VDDB) should rise the specific voltage within 80ms, otherise, the protection circuit
makes the backlight off.
