lm64p70 datasheet
Hello,
i've here a little old ARM7-Board from Sharp, the AEB-1 with the ARM7TDI- Processor LH77790 and an LM64P70 - 640x480-monochrom-LCD, from Sharp too.
The LH77790 has an integrated LCD-Driver with the Pins VD0...7, CP1, CP2, S and MCLK.
The LM64P70 has 14 Pins:
1 S
2 CP1
3 CP2
4 Vdd
5 Vss
6 Vee
7...10 DU0...DU3 Display Data upper half
11...14 DL0...DL3 Display Data lower half
...plus a white and a pink cable (the datasheet mentions CCFT-GND and CCFT-HV,
ground and high voltage from inverter).
It would be nice if this two devices could be connected. Has anyone experience
with this? Good And bad experiences are welcome!
If anyone knows a good information-source (book!?) about LCD-principles (what role plays the inverter and how to build one??), i also would be very thankful.
Greets,
J. B.

ok, i found a good explanation of dc/ac-inverters at tdk:
**broken link removed**
but now... which inverter to choose?
The datasheet of the lcd says about the inverter-parameters:
circuit voltage 1100 Vrms min 1500 Vrms max
serial res - -
discharge curr. 3.5 to 7 mA ac
power consum. 2W
discharge tube voltage 280Vrms
What is meant with the circuit voltage? Is this the "startup-voltage" to get
the tube discharging?
