3. Electrical Specifications
3-1. Electrical Characteristics
The LM220W1 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 which powers the CCFL,
is typically generated by an inverter. The inverter is an external unit to the LCD.

Notes: 1. The input current shall be measured at VDD of 15.0Vdc at 25 , refresh rate of 60Hz, and pixel
clock frequency of 112.2MHz under full white pattern(256gray).
2. This data is for reference for inverter design.
3. The operating current shall be measured at the ground cable at ambient atmosphere of 25 and
does not include loss of external inverter.
4. These value are measured at both end of lamp and are for reference for inverter design.
5. 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.

n T3 : 100 ms (max.)
n T4 : 100 ms (max.)
n T5 : 500 ms (min.)
Notes: 1. Please avoid floating state of interface signal at invalid period.
2. When the interface signal is invalid or no signal, be sure to pull down the power supply, VDD to 0V or
to pull down the PWR_CTRL signal under 0.8V. Invalid signal with VDD and on state of PWR_CTRL
signal for a long period of time, causes permanent damage to LCD panel.
3. BackLight inverter power must be turn on after power supply for LCD and interface signal are valid.
4. Power supply, VDD shall be start under 0.8V.
