Product Specification
LM150X06-A4C3
Liquid Crystal Display
3. Electrical Specifications
3-1. Electrical Characteristics
The LM150X06-A4C3 requires two power inputs. One is employed to power the LCD electronics and to
drive the TFT array and liquid crystal. Another which powers the CCFL, is typically generated by an inverter.
The inverter is an external unit to the LCD.

Note. The design of the inverter must have specifications for the lamp in LCD Assembly.
The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced by
the characteristics of the DC-AC Inverter. So all the parameters of an inverter should be carefully
designed so as not to produce too much leakage current from high-voltage output of the inverter.
When you design or order the inverter, please make sure unwanted lighting caused by the mismatch of
the lamp and the inverter(no lighting,flicker,etc) never occurs.When you confirm it,the LCD Assembly
should be operated in the same condition as installed in your instrument.
Note. Do not attach a conducting tape to lamp connecting wire.. If the lamp wire attach to conducting tape,
TFT-LCD Module have a low luminance and the inverter has abnormal action because leakage current
occurs between lamp wire and conducting tape.
1. The specified current and power consumption are under the VCC=3.3V, 25°C, fV(frame frequency)
=60Hz condition whereas mosaic(black & white) pattern shown in the [ Figure 3 ] is displayed.
2. The duration of rush current is about 20ms.
3. Operating voltage is measured under 25℃.The variance of the voltage is ±10%.
4. The voltage above VBS should be applied to the lamps for more than 1 second for start-up.
Otherwise,the lamps may not be turned on.
