3. Electrical Specifications
3-1. Electrical Characteristics
The LB048WV1 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 LED, is typically generated by a
LED Driver. The LED Driver is an internal 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.
3-2. Back Light Unit
The edge-lighting type of back light unit consists of 12 LEDs, 2 parallel strings of 6 serial LEDs.
