3. Electrical Characteristics
The LVM121XSB-02 requires three power inputs. One is employed to power the LCD electronics and to drive the TFT
array and liquid crystal. 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 current draw and power consumption specified is for 3.3 Vdc at 25oC and fv at 60Hz.(at Black
pattern displayed)
2. Logic level are specified for Vcc of 3.3 Vdc at 25oC. The values specified apply to all logic inputs; Hsync, Vsync,
Clock, data signals, etc.
3. The variance of the voltage is ± 10%.
4. The output voltage at the transformer in the inverter must be high considering to the loss of the
ballast capacitor in the inverter.
5. Lamp frequency may produce interference with horizontal sync. frequency and may cause beat on the
display. Therefore lamp frequency shall be detached as much as from the horizontal sync. and from the
harmonics of horizontal synchronous to avoid interference.
6. The lamp power consumption shown above does not include loss of external inverter.
7. The life time is determined as the time at which brightness of lamp is 50% compare to that of initial
value at the typical lamp current.
