Note: 1. The Relative Humidity must not exceed 95% non-condensing at temperatures of 40¡ Éor less.
At temperatures greater than 40¡ É, the wet bulb temperature must not exceed 39¡ É.
3. Electrical Specifications
The LM151X1-G requires three power inputs. Two inputs are employed to power the LCD
electronics and to drive the voltages to drive the TFT array and liquid crystal. And the third
input which powers the backlight CCFL, is typically generated by an inverter. The inverter is
an external unit to the LCD.

Notes: 1. VDD input is the analog power supply for the TFT array and liquid crystal, and VCC
input is the digital logic power supply for the LCD electronics.
2. The input current shall be measured at VDD of 5.0Vdc at 25¡ É, refresh rate of 60Hz,
and clock frequency of 65MHz under 9 gray pattern.
3. Power supply kick off current means power supply input current at the moment of
LCM power on. This current is higher then the current at the normal operating
condition and it lasts for 50~100ms.
4. The backlight input current shall be measured at the ground cable and does not
include loss of external inverter.
5. Voltages at both ends of the lamp.
6. Voltages at secondary side of transformer using the balancing capacitor, 22pF in
inverter. These voltages can be changed with customer’s own design of inverter.
7. The life time is defined as the time at which brightness of lamp is 50% compare to
that of initial value at the typical lamp current.
