content: Hi!I'm looking for displays for my projects. My go-to choice used to be the nokia 5110 display. As much as I like it, it is too small, and feels very outdated. Resolution is also not enough (84x48 px). So, any recommendations for replacement?I'm also looking for good color displays. I have a few, but they are TN, and I'm not happy with viewing angles and non-uniform picture. Could someone suggest something? I'm looking for 1.8-2.4" size displays.I'm looking both for modules so that I can quickly try it, and bare displays. I tried to google, but didn't find anything useful.To share some experience, I can recommend these 3.5" IPS displays:https://www.aliexpress.com/item/32602544112.html. It's ili9488. The colors a vibrant, the black is black, good viewing angles, and backlight is more-or-less uniform. They are good, but too big for my project. Just one quirk, I have two types of ILI9488: with resistive touchscreen, and without. The one without requires to invert colors in initialization code. Seems to be a common issue, but I didn't find any explanations why some ILI9488 require it, why others not. Possibly a bad clone? The manufacturer seem LiangHaoCai (couldn't find it on google), and it seems it's their official shop on aliexpress or something.I also bought R61529 (which they claim is superior and "sunlight readable"), but haven't tried it yet.There are displays that I also don't recommend, I'll take pictures and share them here.

content: You didn't mention aspect ratio. If a pretty wide aspect ratio in 1.9" fits, I can recommend these IPS panels:https://www.aliexpress.com/item/1005005424391550.htmlYou'll also find tons of ready-to-use modules with these, for evaluation.

content: The next display I have "open-smart st7565 2.4". It's probably the worst display I have (it looks better on pictures than irl).The key issue is lack of backlight. The contrast is poor and puts strain on my eyes. Not to mention cheapish greenish background color. Oh, and also for some reason the picture is offset by 4 pixels. Idk why, another display with presumably on the same controller and the same wiring works just fine.PS small rant. Why displays have so many different connector types? I've seen displays with 8, 10, 18, 20, 30, 40, 45 and 50 wires already. All requiring different sockets(.

content: https://www.buydisplay.com/I think this is generally true for display interfacing, but just a heads up, some of these require more effort to get working than others. Don't expect plug-and-play. At least buydisplay has decent support.

content: Another vote for buydisplay.com. At my old job, we used their 2.8” TFTs in a project, and they’re just gorgeous displays. But above all, the documentation is superb as you’ve seen.FYI, for larger quantities buying from their website is cheaper, but for just a few units, it may be cheaper to buy from their eBay store, where prices are a bit higher but shipping is lower or free:https://www.ebay.com/str/buydisplay
