3v Lcd

[khoog]

Does anyone know of a 3V, 2X16 LCD module (with backlight)?

Well,

it depends...

I'm using GLCD's on several projects.

If you are willing to write your own driver and you can afford the code overhead to drive a GLCD this might be an option:

A NOKIA 7110 LCD would give 8 lines with 16 chars each.
And they are really cheap (less than any backlit character display).

Many other NOKIA LCDs (3310 or other) would do.
(if you can afford the code overhead)

I had a similar challenge, but without backlight. I programmed the hardware PWM to be a squeare wave oscillator at around 10 KHz. I then used two shotky diodes and two caps to double the voltage. After an LDO 5 volt regulator, I had enough power to run the LCD. Hopefully the backlight you chose can be powered seperately from 3 volts. If not, you will need a real boost regulator (try Maxim) to give you enough current for the backlight.

Thank you for your replies.

I have found a Vishay part: LCD-016M002L that may do the job.

I like the idea of a cell phone type graphic lcd.

Need to find a generic version- all I could find on the Nokia part were cell phone surplus parts for hobbyists. Can't really design those into a product because they may not be available 2 or 3 years down the road.

Thanks again,

Klaus,

It is a matter of quantity

Say your your target is 1k per year for the next 3 years.

So you would need 3k LCDs.
Why don't you just get them now at far less than $1 each (@ a quantity of 3k) and put them on the shelf?

I agree, there is not much of a chance of the same kind of display being available in three (or five) years time, but who cares, Wouldn't you have re-designed your product anyway in 2010?

And having a GLCD makes your product look much better than the competition (if there is any)

Ralph:
Do you can give us the part number and the supplier of those displays.?
Thanks in advance...
