Does this have touch screen capabilities?

Is this compatible with the sigma?

I recently purchased this screen to use with the LattePanda 2 Alpha; the first several times I used the screen it worked fine, but now it won't display anything despite the keypad module showing that the device is receiving power. Does anybody know how to fix this problem?

i know it should be possible to run a Lattepanda 3 Delta and this display from 18650 batteries — any tips on how many i'll need to run them safely?

I was thinking of connecting this display to the Lattepanda Alpha, but I was also wondering if there was a way to install a really small camera. If I connect it to the Lattepanda Alpha, is there a way to connect a very tiny camera? Is there a camera you would recommend?

Do you have a case that would hold this monitor? I would like to be able to use this as a mobile monitor that I could take out on service calls. Preferably a case that would hold the board on the backside so it was all in one, would just need a power connection and a cable to either Raspi or Lattepanda
