I don't know if this LCD is compatible or not. But the 7" 1280x800 (Model: hsd070pww1) IPS panel
I haven't a clue of this panel is compatible with the LP. i'm trying to find some pinout information atm.

3.5 inch is the size we would like as it is a size appropriate to embed into 2U high 19inch rack standard units. We develop industrial machines normally controled from 19inch rackmount units and we are evaluating to use Latte Panda as the main board in these controllers. 2U is a great size for these controllers, more is too big. More than 3.5 inch screens are too big to fit adequately onto the front of a 2U high rackmount box.

Alternatively to my previous post, maybe a good idea is to have a converter from the Latte Panda video/touchscreen connectors to the SPI video/I2C touchscreen that for example devices like Waveshare 3.5inch RPi LCD (A) V3 have. Plus the corresponding Windows driver.
Besides this particular model we are actually using, there are many LCDs in the market with SPI interface for video and I2C for touchscreen.

The 3.5" LCD of choice that i used in projects, was the PD035VX2. With driver board they're admittedly a bit expensive, at $80+ from china.
they are 3.5" 640x480 resolution. Which is the best res i could find for a 3.5" that could support hdmi/vga etc.
i used one inside a gameboy with a raspberry pi 2 and a skimmed down hdmi to vga adapter.

Mine had VGA and composite only, i only used the VGA of course, which worked great at that resolution.

I've been hoping to find a way to use some LCDs from smart phones, since the one in my smart phone is larger, 4" but it's long(wide) so it would fit in a U2 case panel, so long as it's made wide enough, and of course smart phones have multi-touch. You'd have to find an adapter for it, one that supports the multi-touch. Which won't be easy and you'll likely have to use an FPGA.

Thanks for your feedback. we will now be offering 5.5”, 10”, 11.6” and 14” MIPI displays that connect directly to the board. These will launch on the DFRobot store alongside the next batch of boards (current lead time is within two months).
Enjoy Tinkering with LattePanda ! :lol:

3.5 inch is the size to be able to build 2U high 19" standard rack devices, with a touchscreen at its front. Very usefull for industry control racks.

Any estimates on the prices? Do they come with touchscreens? If yes, are they sold seperately again or already builtin the display?

Samples in our office and we are in the process of working out the supply chain. A release date is not finalized yet but will let you know when I have more information.

Image
Here you can see a 5.5" screen. Currenlty the mipi connnector needs to be customized to a 30pin connection. I have placed it next to the 7" screen and a LattePanda for scale.

Here is an 11" screen. The connector also needs to be customized.

Image

we have released drivers for a new touch panel here and these will release along with new screens
Enjoy Tinkering with LattePanda ! :lol:
