Frage:
Our factory is looking for graphic LCD display for our prototype. I have read somewhere, that you are selling displays - and I have even found the type - 320x240STN with CFL-backlight (EA 7320-7,9NC), but I would like to get something technical information about it: I would like to know:
1.Power consumption (with and without backlight)
2.Power supply( voltage)
3.If it is equipped with contoller (if no - what type of controler it needs and have you got any ?)
4.Price of full kit or parts (I mean display, controler and backlight)

Antwort:
Thank you for your email response. Here are the answers for your questions. Please note that these datas are only valid for the EA 7320-7,9NC: - The Power Supply Current at VCC is max. 15mA, at VEE max. 10mA.
- The logic voltage is 5V ±10% and the driving voiltage for the contrast is -14..-21V (it depends on the temperature)
- For driving the lcd you need a controller chip like SED 1330 or MSM 6255 and some driver, display memory and decoder. Then you have to write a software with graphic routines, fonts ...
Furtherwards you need an CFL inverter for driving the CFL backlight (e.g. EA CXA-E005 DM 29,00 per pc.) - The price for the full featured RS232 KIT (EA KIT7320-V24) is DM 850,00 per pc. Here you will get 5 intergrated Fonts, various graphics functions and an RS232 interface. The power supply is simply 5V. You do not need a CFL inverter anymore.
