LCD bargraph display

Hello

I found this display by surfing on the web:

http://www.lcdexceltech.com/lcdpdf/0264.PDF

Unfortunely I couldn’t find anything about the operating voltage.

Does anybody know more about this “DIL E” connention type?

Do I guess right, that this display doesn’t need a controller, that each bar is activated over individual pins.

If yes, could I use this display as a substitude for led graphs in my MidiBoxLC and connect the pins instead of LEDs?

Thanks and greets

Roger

I tried to get some information from this company. They didn’t even respond to my mail >:(

DIL E? No idea.

But normally you canÂ´t use LCDs as a direct substitute for LEDs. The operating stuff is totally different. E.g. some LCDs need negative voltage for contrast and positive voltage with higher current (like 100 mA) for backlight.

… strange, that this is not specified on the datasheet. They write unter driving sheme: “direct”. So I thought, who knows, perhaps they could be driven like a substitude for LEDs 8)

Thanks for the input pay_c
