Question

Display recommendations for a custom STM32H743IIK board?

Hi!

I am looking for a display for a custom board as above with these overall specs:

  • Size 6 - 10" TFT-touch.
  • High resolution e.g. 800x480, 1024x600.
  • > 1000 nits for outdoor use in sunlight (e.g. industry, marine classed)
  • Preferable coming with plugin connector-cable to attach to board
  • Built in memory (is this possible?)
  • Very small quantity so quality above all

Any recommendations would be highly appreciated!

Thanks in advance

Many thanks Tesla,

However, if I did not misread, these displays seem to be intended for indoor use. Their 10.1" product have a a brightness of 800cd/m2 (nits) which is a bit to low to handle direct sunlight.

They have a lot of range and ability to source panels, you should perhaps have a conversation with them. I understand the high nit requirement, but it's a niche and expensive area, so made/designed-to-order is actually a viable business. Can perhaps match with controller IC's with frame buffers too.

Many thanks again!

I think I could manage board size, pins and so on for both the DSI and parallel interface.

However, I get a bit of bad feeling when you mention cabling issues with DSI... I would really like to have an easy board connection, preferable with some sort of standardized connector. Perhaps risk mitigation is needed here, so much else could go wrong I mean.

It would be great to add a standard a HDMI-connector to the PCB and being able to plug in any of a myriad of display options via a standard cable! But if I am not wrong, not even the STM32MPU:s have HDMI-support and thus one would perhaps need to consider a NXP i.M8 or similar. Anyway a Cortex-A seems to be needed and it turn would need Linux/Android. I am afraid such project would be to complex for me.

Or have I missed anything around the HDMI?
