LCD data are output from pin C19 of IC101 to LCD module.
LCD contrast is set by electronic control in LCD module.
+3.3V of the power supply voltage is pressurized about four/three times in the LCD module and used as LCD driving voltage
(approx. 10V).
The driving voltage is observed at pin12(VLCDIN) of CN1.
The lighting of the backlight is controlled by Q403.
The PWM (Pulse Width Modulation) signal is output from IC101 (pin U13) pin and the brightness is changed according to its duty
ratio.
