Can’t believe it’s not OLED
It is very hard to get low resolution small oled screens. Cell phones use pentile displays that are about 60% the actual RGB resolution of the input they need. You would be looking at it needing to be outputting in the 4k range on a 1440p ish display to use off the shelf parts.
If you wqnted to have a 1080p RGB oled it would need to be about 11" and that is too big. It would also have burn in issues with any reasonable brightness.
Lcd would be fine at a higher resolution imo. But… Are they staying with 720p again?
720p is pretty solid on small screens when you’re holding it ~2-3ft away. 1080p would be more ideal for sure, but I wouldn’t be that disappointed if it means better battery and performance.
