Bigger SPI TFT displays ?

Projects General Guidance
1

Hi all, I'm having great fun with various ESP32 projects, using cheap 4.0" SPI touchscreens with ili9431 drivers.
I'd like to try bigger displays, but it looks like a mine-field.
Best way to go to a bigger screen size ?
Maybe 7.0" ?
Thank you

I suspect the interface and display controller become more important once you move to larger displays.

try searching on Amazon, Ebay, etc for 7 inch display esp32, e..g. ESP32-S3 HMI WIFI&Bluetooth 7.0 inch Smart Display

Thanks Horace, I'll have a look

I have used the 2.8" and 4" ESP32 based CYD displays but not the 7"
make sure you have technical details of any display module under consideration, e.g. display driver chip, GPIO usage, pinout, etc
often the web pages have lots of general text and photos but totally lack technical details

Thanks for your help Horice, I have contacted a couple of sellers of 7" screens on eBay, but eBay is making it difficult for me to get the technical info and data sheets.
We'll see.

a common problem! without GPIO details etc it is difficult to program the devices

have a look at Waveshare ESP32-S3 7inch Capacitive Touch LCD Development Board, ESP32
I generally find Wavewshare documentation is very good - see the ESP32-S3-Touch-LCD-7 WiKi

I see it is available on Amazon in UK

Thanks Horace I'll have a look.
Probably wise to start learning LVGL first, using my existing displays. I've used Bodmer's TFT-espi up until now.
