I'm working on a small 65C02 project that's going to use an LCD screen as a primary display. I already have a 20x4 LCD. I assumed anything larger didn't exist. I searched and found nothing. Well, either my search terms were way off or something as I later found 40x4 LCD's on eBay and Aliexpress. They're a little pricey at around $20 shipped. Not the end of the world but smaller LCD's are much less. So I assume they are pricey because they were never common.

Have you guys seen many LCD's that size in the wild? Do they get larger?

Cat; the other white meat.

I remember using a 40x4 one many (30?) years ago for a project. It was very expensive - more like over £100 at the time! But since then the largest I've used is 20x4.

Mouser has them for about £20 so probably the same in USD if you didn't want to buy via ebay...

Hm. they also have a 40x8 one too, but that's somewhat more pricey and out of stock... It would make for an interesting display for a hand-held though, but I suspect that these days that resolution is achieved much more cheaply using a graphical LCD type at the expense of more software needed to drive it from a 6502 (font, etc.)

Also be aware that some of the generic 16x2 ones are missing the user-definable character font RAM! I found this out recently - all to save a few cents by the clone makers, I guess...

Cheers,

-Gordon

I think 40x4 is the largest size that's moderately easy to get hold of. Beyond that, you might as well go for a full graphical LCD.

40x4's are still easy to get (last I checked). There used to be 80-column ones back when typewriters were going electronic and everyone didn't have computers with printers and word processors yet. I think that segment of time was pretty short.

What's an additional VIA among friends, anyhow?

I got one recently for a project, the PCB hasn’t arrived so I haven’t got it going yet, but the data sheet says that it has two controllers, complete with their own chip selects, each controller is responsible half of the display.
