I have data sheets on Sharp ( electronics corporation ) LCD units circa
1988.
They Show a LM64015T Display which was also 640 X 400.
Its logic was 5.0 V (MAX 6 V) and the Supply (LCD) drive is Typical -21V
(Min- 32V. Max -14V)
It was driven with a Yamaha V6366 display controller.
There is also a TDK CXA-1301 Inverter spec'd which provides CCFT backlight
voltage ( Typical 1000 Vrms _at_ 400hz)
The Sharp LM64015T display is a 12 pin device,
Pin 1 labelled S for Scan Start up high
Pin 2 CP1 (clock pulse 1) Input Data latch (High to low)
Pin 3 CP2 Data Input Clock Signal ( High to low)
Pin 4 open
Pin 5 NC
Pin 6 Power supply for Logic
Pin 7 Gnd potential
Pin 8 Power for LCD Drive
with pins 9-12 being display Data, D0 - D4 respectively - (High on)(Low
off)
This gives an Idea of typical voltages and interfaces of the era. This may
not apply to the Specific Matsushita device you asked about. It points out
that there are often Display Controllers Like Yamaha V6366 and High Voltage
inverters like TDK CXA -1301 ( 100V- 1000V) for backlighting.
Sincerely
Larry Truthan
