Topic: Bigger lcd alphanumeric screens (Read 677 times) previous topic - next topic

Hi all!
I know that for Arduino there are the 1602 and the 2004 alphanumeric displays.
Do you know if is there a bigger alphanumeric display?
(Not a graphical one, I know about the 12864 etc)

Thanks

Are you looking for more characters or physical size?

Both,
I'm looking for a bigger screen in size and of course more characters but with the same "style" and type of screen.

To give an idea I'm looking for something similar to a screen made of smaller screens put one next to the other.

Sure there is, 40 x 4 screens are common enough.

That's what I was looking for, thank you!

Thank you, too!

Not a problem.

I have used BuyDisplay since about 2013, and, if you don't have a problem with the shipping lag, you should be very pleased with the quality of their products.  So far, I have not had a defective component or sub-assembly from them, and just ordered their development board for the 40x04 display....just out of curiosity and general boredom after a busy Summer season.

If, however, you need the display yesterday...LOL...you might want to consider other suppliers.  I believe that shipping to me, in Southern California, takes about 3 weeks.

I have no rush so it's ok, thank you :)

Thats OK, it did take me a while to think what to use as a search item in Google, as in what would be a 'bigger' screen than a 20 x 4.

I've tried a lot of combinations but never 4004 ahahahh

I can understand, its not intuative that a 40 character display would be the next size up from a 20 charcater display.

Yup quite impressive as complexity.
In fact 16x02 then 20x04 then 40x04, straight forward.
So I think that you know all the series.
Than 80x08 or 80x04 or 60x04 ?

Well, so far at least, 40x04 is the largest LCD character display that I've seen available to the consumer/hobbyist market.  If somebody out there *is* selling something larger, I'd be interested in seeing tech specs on the hardware.

I presume that, because of economic forces, and the limitations of 4-bit / 8-bit address lines, the next logical step up would actually be an LCD or OLED graphics display panel; which would, of course require more resources from the host micro-controller board.

Oh....I almost forgot to mention that, as with the 40x02 displays, you WILL NOT be able to use the run-of-the-mill i2c / SPI character LCD backpack boards to simplify the addressing scheme from the controller board to the display itself.  Most of those top-out at 20x04.

However, Akafugu does supply an imminently capable TWILCD backpack board here:
