activates the vertical drive circuit and vertical
output circuit.
When the vertical drive circuit and vertical output
circuit are in action, it is only in the
period
that the booster (pump up) circuit is allowed to
operate to provide the voltage about twice
I) The design that the supply voltage is boosted only
in the
period results in remarkably reduced
power consumption.

must
be supplied until the
pulse voltage reaches
its highest value. In this circuit, however, it is
sufficient to use about half of Vcc for the circuitry
operation.
