I have a project that will need a small touch display. It will be used in public buildings to control an alarm system.

Once the prototype has been built, more of the displays will be ordered.

The requirements for the project are:

• Touch display (preferably resistive)
• RS485 connectivity (to enable the display to be a good distance from the hardware)
• Cost per display is a consideration when ordered in volume (200 per year or so).

The display doesn't need to be very big (4" or even less would work), and the resolution doesn't really matter either, as long as it's adequate for buttons and text.

If you know how visual elements are configured to the display (for example by using QT), that would be helpful.

Thanks for any help or direction!
