The Raspberry Pi comes with a host of useful extras, from handy cases and the popular Pi Cam module. about hats, expansion boards of great extensions which connect to the Pi’s GPIO pins. But the 7-inch Raspberry Pi touch display kit has proven to be especially popular.
While a variety of displays are available for the Pi, few are as versatile and flexible as this official Raspberry Pi product. But if you ordered one, you might not know how to proceed. How to connect a Raspberry Pi touch screen to a Raspberry Pi computer?

What’s in your pi?
Before proceeding (preferably before buying!), you should take a look at your Raspberry Pi device. Despite being compatible with all standard boards, you will find it difficult to set up a Raspberry Pi touchscreen with the Pi Zero. because the device does not have all the necessary connectors.
However, if you have a standard Raspberry Pi model B, B+, 2, or 3, you can use the Raspberry Pi touch screen with this device.
But… there is one more caveat. Only Revised Raspberry Pi 2 PCB Design and Raspberry Pi 3 compatible with the mounting screws on the back of the touch display. This means you will need to take other steps to securely attach (or otherwise) the old Pi board.
We will now continue learning how to attach a 7″ Raspberry Pi touch display to a Raspberry Pi 2 or 3 board.
Leave the protective film in place!
One thing you shouldn’t do until your Pi and your touchscreen display is properly wired and connected is to remove the protective film that’s already applied to the display. It might look unsightly, but it doesn’t matter at this stage — the important thing is that you can protect your new touchscreen device from any scratches and scratches that may occur during the connection process.
So do yourself a favor and leave the protective film in place for a little longer!
Update your pi
You need to make sure your Raspberry Pi is properly configured to use the touchscreen before connecting devices. To do this, boot up your Raspberry Pi and enter the following commands in the terminal, waiting for each to complete before typing the following:
sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade sudo apt-get install raspberrypi-ui-mods sudo apt-get install raspberrypi-net-mods
This will ensure that all the correct drivers and interface software applications are installed before connecting the touch screen display.
With these updates installed, we can get to work. Time to get out your toolkit!
Connect display board to touch display
Take extra precautions before connecting your Pi to a touch screen. You must either leave the display in the box, but face down so that the touchscreen rests on the foam wrap, or lay it face down on a towel on a table.
Then check if the display board is connected to the orange ribbon cable and the display. In older boxes, you will have to do this manually; our new box, with these components already linked.
The orange ribbon cable connects at two locations on the display board; the narrow end connects to the Panel 1 connector, which has a small clip that will need to be undone before the tape can be inserted and tightened again. The wider tape connects to the other side, to the connector labeled Panel 2, in the same way. Use four spacers to attach the display board to the back of the display and you’re good to go.
