  • Thanks - yes, that's the datasheet I used - but I could really do with a bit more info about how the greyscale is handled on ST7301 (I think there are different modes).

    It was this one: https://www.aliexpress.com/item/10050053­00414591.html - KD042WQTMN001

    So not super cheap, but not bad one-off (although you need an FPC breakout) for it.

    It's a really nice display though. Around 85x65mm viewable area, with maybe a 3mm border. When running in the low power more I reckon it's using about 100uA or less, and it's really sharp.

    I'm seriously considering it for a new Pixl.js type device assuming I can get them in quantity cheap enough.
