Note: 1. The Relative Humidity must not exceed 95% non-condensing at temperatures of 40º or less.
At temperatures greater than 40º, the wet bulb temperature must not exceed 39º.
2. Current shall be measured at ground line.
3. Electrical Specifications
The LM151X2 requires two power inputs. One input is employed to power the LCD electronics and to
drive the voltages to drive the TFT array and liquid crystal. And the second input for the backlight CCFL,
is typically generated by an inverter. The inverter is an external unit to the LCD.

Notes: 1. All values shall be measured at the user connection.
2. The input current shall be measured at VDD of 3.3V at 25 , refresh rate of 60Hz, and clock
frequency of 65MHz under 9 gray pattern.
3. The backlight input current shall be measured at the ground cable and does not include loss
of external inverter.
4. Voltages at both ends of the lamp.
5. 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.
6. 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.
7. Power supply kick off current means power supply input current at the moment of LCM power
on. This current is higher than the current at the normal operating condition and it lasts for
50~100ms.
