• Manufacturer Part Number: NL160120AC27_01
• Description: TFT COLOR LCD MODULE
• Manufacturer: NEC

(6) The protection circuit makes the backlight turns off, when BRTP signal “L” input more than 50 ms.
(5) Analog RGB inputs are independent from this power supply sequence.
(7) Do not input ACA signal ”H” and/or PWSEL signal ”H”, if VDD is 0V or BRTC signal is “L”.
(8) Ripple of supply voltage
(9) Inverter current wave
Example of the power supply connection
Note 1: The acceptable range of ripple voltage includes spike noise.
