Electrical Specifications
The LM181E1 requires two power inputs. One is employed to power the LCD electronics and to drive the voltages to
drive the TFT array and liquid crystal. The second input which powers the backlight CCFL, is typically generated by
an inverter. The inverter is an external unit to the LCD.

Notes: 1. The current draw and power consumption specified is for 12.0 Vdc at 25℃
and fv at 60Hz. The LCM is displayed the 8-gray pattern for the typical current.
And the maximum current measurement condition is the vertical 2-line white/black pattern.
2. Logic levels are specified for 3.3Vdc at FPD-Link chips, transmitter & receiver. The values
specified apply to all logic inputs to FPD-Link; Hsync, Vsync, clock, data signals, etc.
3. The backlight current consumption shown above does not include loss of
external inverter.
