Hi all,
I’m new to Arduino and I’d like to buy a LCD, I did some research and I found different LCD’s. The ones I found are mostly 16x2 or 20x4 characters.
I’d like to program an LCD so that it shows kind of a to-do-list, but 2 or 4 lines it not enough. So I’d like to buy an LCD with at least 10 lines, and if possible one that runs on batteries. I’d like to be able to move it around on my desk and wires kind of make that undoable. Is this possible? What do you recommend?
Thanks in advance!

There are plenty of graphics LCDs that would display ten lines of text, and they can all run on battery. All you need is a battery that is the right size.

You appear to have answered your own question. The main problem is probably the packaging, where a lot of effort will go into packaging a bad idea.
What do you recommend?
I recommend you sit back consider the situation, it can't be hard to think of something more useful than this. You could make a list using pencil and paper.
It is possible to let a LCD display scroll text horizontaly, left to right or right to left, like a newsreel. In this way you van even with a siple 16x2 LCD achieve a lot.
My challenge was to display 10 heat sources and their temperatures. This was done on a 20x4 LCD by presenting four objects/temperatures, then clear the screen, present the next four objects/temperatures/ clear screen, etcetera.
After a year I switched to 240x320 TFT screen. Such screens can display all 10 objects/temperatures in one screen and have space for more information. See https://thesolaruniverse.wordpress.com
by the way I am making 'to do' notes on my smartphone. No wires, always with me.
