Some context - I'm looking for a 5" display for a project that will be controlled by a Nordic nRF52840 SoC. I'm using the nRF Connect SDK which is based upon the Zephyr OS and has built-in display driver support (for typical SPI interface controllers like ILI9488/ILI9340/ILI9341/ST7735/etc) as well as the LVGL graphics library. Ideally I'd like to go with something that is easily integrated with Zephyr OS. The application of itself is not demanding of the display at all (text on screen with relatively low refresh rate), so I'm not concerned about update rate/etc. Trouble I'm running into is I can't find any SPI displays around 5" that use a display driver already supported by OS (see list above), and additionally I see a large cost difference between the parallel type displays and those with an SPI interface. So that drives me towards the parallel interface route. I've been wavering between the nRF52811 and nRF52840 chipset, but if I go with the latter that gives me plenty of GPIO pints for even a 24-bit interface. So I'm inclined to go that route, however, I have a few struggles:
