5. Electrical Specifications
5-1. Electrical Characteristics
The LB080WV3-B2 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.

Note)
The design of the inverter must have specifications for the lamp in LCD Assembly. The performance
of the Lamp in LCM, for example life time or brightness, is extremely influenced by the characteristics of the
DC-AC inverter. So all the parameters of an inverter should be carefully designed so as not to produce too
much leakage current from high-voltage output of the inverter. When you design or order the inverter, please
make sure unwanted lighting caused by the mismatch of the lamp and the inverter(no lighting, flicker, etc)
never occurs. When you confirm it, the LCD Assembly should be operated in the same condition as installed
in your instrument.
* 1. Vcc=5.0V, 25°C, fV (frame frequency) = 60Hz condition, whereas mosaic pattern(Typ.), full black
pattern(Max.) is displayed. [LDO output voltage(Vdd=3.3V) is applied.]
* 2. This frequency range means the range to keep within ±10% change of electrical and optical
characteristics.
* 3. This frequency range means not affecting to lamp life and reliability characteristics.
(The lamp frequency should be selected as different as possible from display horizontal
synchronous signal (Including harmonic frequency of this scanning frequency) to avoid “Beat”
interference which may be observed on the screen as horizontal stripes like moving wave.

5-5. Color Input Data Reference
The brightness of each primary color (red,green and blue) is based on the 6-bit gray scale data input for the
color ; the higher the binary input, the brighter the color. The table below provides a reference for color
versus data input.
