3. Electrical Specifications

3-1. Electrical Characteristics

The LP141WX3 requires two 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.

1. The specified current and power consumption are under the Vcc = 3.3V , 25℃, fv = 60Hz condition

whereas Mosaic pattern is displayed and fv is the frame frequency.

2. This impedance value is needed to proper display and measured form LVDS Tx to the mating connector.

3. The typical operating current is for the typical surface luminance (L

4. Define the brightness of the lamp after being lighted for 5 minutes as 100%, Ts is the time required for

the brightness of the center of the lamp to be not less than 95%.

5. 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.
