2.3 ELECTRICAL CHARACTERISTICS
2.4 FUSE
Note1: When designing of the power supply, take the measures for the prevention of surge voltage.
Note2: The power supply lines (VDDB and GNDB) occurs large ripple voltage while luminance control
Note3: Measured value with high voltage probe of a load capacitance of 3pF
Note1: The power supply capacity should be more than the fusing current. If the power capacity is

of LCD lamps. There is the possibility that the ripple voltage produces acoustic noise and signal
wave noise in audio circuit and so on. Put a capacitor (5,000 to 6,000
source lines (VDDB and GNDB) to reduce the noise, if the noise occurred in the circuit.
It is guaranteed that the adaptable LCD module can be turned on at Ta= 0
less than the fusing current, the fuse may not blow for a short time, and then nasty smell,
smoking and so on may occur.
