Title: Raspberry Pi Touch Display
Post by Jeanette on Dec 1^st, 2015, 11:36am

I'm seriously considering the Raspberry Pi 2 Model B and I may or may not get the Raspberry Pi display.

https://www.raspberrypi.org/products/raspberry-pi-touch-display/

Does anyone have experience with it? I want to put together a versatile end user system. One I can take with me when I travel but can also run off of a battery in the event of power loss or an emergency. If I attach the display, it must be done in a way where it can be transported without being damaged. It will be in a Faraday bag when not in use.

For the purpose of protecting the computer, I want to get the case.

Can I protect the computer with the case while it is attached to the display?

The R-Pi's screen has one advantage no other screens have - it connects to the R-Pi's LCD Screen Port (Tiny White or Black Slot near the GPIO Port towards the end of the board).

I believe that the ribbon is already reinforced but to strengthen it further you can use packaging tape to sandwich the ribbon into, leaving off a 1/2 inch bare on each side to connect to the screen and board, and some overhang on the side so that the tape breaks before the ribbon does.

The touch screen has a mounting bracket on the back to put a bare R-Pi on to it. I do not know if you can use a cased-in R-Pi onto that bracket. You might have to make an invention with glue or velcro to attach the cased-in R-Pi to it. See Engadget's link as to how it is hooked up:

They are supposed to go for around $65, but I suspect by the time that screen comes to the USA, it will be closer to the $100 area.

Since it connects to the R-Pi directly, the R-Pi powers it. Thus i you are using a battery to run it, expect the battery life to be cut in half. My experiments shows that a 2600mah cellphone battery pack charger will run a R-Pi for 4 to 6 hours, so with the LCD, it would be 2 to 3 hours, which is respectable as far as laptop batteries go for. If you run more than one battery pack, run them in parallel, not in series - and it will increase battery life times the number of batteries you use.
