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

(3) The backlight ON/OFF (BRTC signal) should be controlled while logic signals are supplied. The
(4) Keep POWC signal "L" more than 200 ms after the power supply (VDD) is input, if POWC signal is
input voltage to signal lines is higher than 0.3 V, the internal circuit will be damaged.
CLK, Hsync, and Vsync is not input more than 90 ms typically. As the display data are unstable in this
period, the display maybe disordered. But the backlight works correctly even this period. So the
backlight should be controlled by BRTC signal.
controlled.
backlight power supply (VDDB) is not related to the power supply sequence. However, unstable data
will be displayed when the backlight power is turned ON with no logic signals.
