Are there any commonly available and supported backlit, monochrome graphic LCDs with more than 128x64 pixels? I am currently using a ST7565 graphic LCD for display in a heat pump system.

This LCD has the following characteristics:


128x64 pixels
2.5"x1.5"
monochrome, no greyscale
backlit
good viewing angles
serially connected (i.e. only uses a small number of pins)
high enough refresh rate to show animated icons
low cost (£20)
has a high-quality, maintained library
available from multiple sources for several years


I am finding the resolution of the screen limiting for my application. Ideally I would like a display that is exactly the same but with a higher resolution. Something between

I do not want:


colour (largely as the display is less visible, but also increased cost and code complexity), but red/green/blue on black would be OK.
a physically smaller display (all of the OLED displays are small - 2" and below) as it needs to be visible from a distance


Are there any displays that meet these requirements?

I hope that the specific requirements here mean that this is not a simple "shopping question".
Here you can find a bunch of displays at new haven display, which are big and OLED and not too expensive:


2.7" 128x64 OLED
3.12" 256x64 OLED


Those OLED Displays have a really excellent viewing angle and can be read from far (given you accept those sizes, which are >2").

Otherwise, the biggest I know about are LCD ones from NHD over there:


320x240 LCD with backlight


What's good with them, it's that they can cope with production in case this is needed, their prices are decent and their product just work(cTMr). You can find the u8g library to run them.
