BRTH should be fixed to 0V to
control luminance by voltage.
The range of input voltage
between BRTL and GNDB is as
follows.
Maximum luminance (100%) : 1V
Minimum luminance (30%) : 0V
Latch pulse2 for display control data

Description
The variable resistor for luminance
control should be 10kΩ type, and zero
point of the resistor corresponds to the
minimum of luminance.
Maximum luminance (100%): R=10kΩ
Minimum luminance (30%) : R= 0Ω
Mating variable resistor: 10kΩ ± 5%,
