Note: The capacitive touch function does NOT work with the latest Raspberry Pi OS - Bullseye (release date: 30th October 2021). You can revert back to Raspberry Pi OS Buster following this tutorial.

This is the official 7” Touchscreen Display for Raspberry Pi from Raspberry Pi Foundation. It gives users the ability to create all-in-one, integrated projects such as tablets, infotainment systems, and embedded projects!

NEW RASPBERRY PI GOODIES! Today the Foundation has just released a brand new product: their very own official Raspberry Pi 7" Touchscreen DSI Display. Featuring a resolution of 800x480 pixels, 10 point capacitive touch as well as a low $60 price point, the display promises a lot... But how does it actually fare?

The 800x480 display connects via an adapter board that handles power and signal conversion. Only two connections to the Pi are required; power from the Pi’s GPIO port and a ribbon cable that connects to the DSI port present on all Raspberry Pi’s.  Touchscreen drivers with support for 10-finger touch and an on-screen keyboard will be integrated into the latest Raspbian OS for full functionality without a physical keyboard or mouse. If you like to keep it in a nice casing, check this Premium Case for this Screen.

Make your own Internet of Things devices including a visual display. Simply connect your Raspberry Pi, develop a Python script to interact with the display, and you’re ready to create your own home automation devices with touch screen capability.

A range of educational software and programs available on the Raspberry Pi will be touch-enabled, making learning and programming easier on the Raspberry Pi.

Note:The display will technically work with the Model A and Model B boards (connecting it to the DSI port on the Pi board), however, the mounting holes on the back of the display will only line up with the newer board designs (A+, B+, Pi 2, and Pi 3).

Mount your Pi Touchscreen with a professional look. We make the mold tool and then injection mold the parts in-house, here at SeeMeCNC. The included screws will mount your Pi touch screen to a sheet metal enclosure. We also include screws to mount your screen to a stand or thicker surfaces.

Both the display driver board and the Pi need power- you can bridge them using the red and black jump wires supplied from the 5v and GND on the display driver board to the 5V and GND on the Pi ( find them here: http://pi.gadgetoid.com/pinout ) then plug the power into the display board.

If your touchscreen or display doesn’t work, triple check the FPC connectors - I’ve tested a lot of “not working” LCDs to find them working perfectly. In all cases the cables should be pushed in firmly and the clips secured fully- the larger FPC for the display ribbon takes quite a bit of force. I’ve posted a guide to the FPC connectors here: http://forums.pimoroni.com/t/raspberry-pi-official-7-touchscreen-assembly/1132

If you’ve got any reservations about connecting wires to your Pi’s GPIO, I recommend our split dial microB USB power cable: https://shop.pimoroni.com/products/split-microb-usb-power-cable

Make sure you update your Pi first, you’ll need the latest software and the Raspbian OS in order to drive the screen. A full reinstall of Raspbian Jessie works best, you can find it here: https://www.raspberrypi.org/downloads/raspbian/

Follow the linked Installation Guide, and make sure you go into Menu -> Preferences -> Raspberry Pi Configuration and expand your filesystem when you first boot up your Pi.

There’s no better place to learn everything you might need to know about the screen than the Raspberry Pi blog post which you can find here: https://www.raspberrypi.org/blog/the-eagerly-awaited-raspberry-pi-display/

The touchscreen works over the DSI connector, so no extra connections are needed. It’s connected to the driver board via the smaller ribbon cable- don’t forget it!

This is unfortunately a side-effect of many developers assuming a minimum screen resolution of 1024x768 pixels. You can usually reveal hidden buttons and fields by;

Yes and no. As explained in the official Pi blog on the subject, only applications which know how to output over HDMI can be used. An example is given for OMXPlayer: https://www.raspberrypi.org/blog/the-eagerly-awaited-raspberry-pi-display/

It is possible to use both display outputs at the same time, but it does require software to choose the right display. Omxplayer is one application that has been modified to enable secondary display output.

Please note, you may need to increase the amount of memory allocated to the GPU to 128MB if the videos are 1080P, adjust the gpu_mem value in config.txt for this. The Raspberry Pi headline figures are 1080P30 decode, so if you are using two 1080P clips it may not play correctly depending on the complexity of the videos.

Currently you can’t run a dual display X desktop, and we don’t know when or if this will be possible. If you know how to make it happen, you can chime in on this thread: https://www.raspberrypi.org/forums/viewtopic.php?f=108&t=120541

Note: An update has been pushed to Raspbian to flip the screen ( rotate it by 180 degrees ) for a better desktop viewing angle. This makes it upside-down in our stand and the official Pi stand, so you’ll need to change a setting to flip it back.

With the software updated it’s actually reasonably straight-forward to get the touchscreen working with a Model A or B Raspberry Pi. First you must make two additional connections between your Pi’s GPIO and the touchscreen: these are the SDA ( http://pinout.xyz/pinout/pin3_gpio2 ) and SCL ( http://pinout.xyz/pinout/pin5_gpio3 ) lines ( which you can connect using the supplied green and yellow wires ).

Note: This will give your i2c over to the Pi for running the LCD/Touchscreen and you wont be able to use any other i2c devices or add-on boards which require i2c.

If you absolutely need an extra 10 degrees of vertical viewing you can fit a Pibow Coupe to the back of the LCD screen and remove the legs. This lets it rest slightly further back while still remaining stable enough for everyday use. It also fits pretty neatly into a bag, too.

If you get a black screen, it likely means your DSI cable ( the one between the Pi and the driver board ) isn’t seated correctly or is… backwards ( I’m not even sure this is a real thing! ). We’ve had some success reversing the cable in this case- switching which end plugs into which part.

I’ve tried a number of USB cables from the USB port on the LCD driver board to the power input of my Pi and have invariably seen the little rainbow square indicating undervoltage in the top right hand corner of the LCD. (Note: This has seen been updated to a lightning bolt indicating the same)

I have put together a prototype split cable, and we’re looking into sourcing microUSB cable splitters to use in conjunction with the official Pi power supply as the most reliable solution.

Chris_c on the official Pi forums has discovered how to enable right-click with a simple configuration change. This allows you to press and hold on the touchscreen to trigger a right click.

As Clive demonstrates below, you can make a much more compact setup by flipping your Pi and mounting it with the ports facing towards the back of the LCD.

A standard GPIO ribbon cable will not fit between the two metal risers, so it’s impossible to route a Black HAT Hack3r or Cobbler out from the display in this position, but there might be cables out there that fit.

Gasp! Okay, I can see why you’d want to do this! I couldn’t put it better than the great step-by-step forum post here: https://www.raspberrypi.org/forums/viewtopic.php?f=108&t=120793

You can find a technical drawing with dimensions of the display and mount hole locations here: https://github.com/raspberrypi/documentation/tree/master/hardware/display

Make sure you mount your screen by screwing, gently, into the mounting holes either side of the metal frame, or for the driver board. Don’t attempt to mount the screen by the glass front. The tape bonding the glass to the rest of the screen isn’t designed to carry the weight of the screen, your Pi and whatever else might be connected.

The Compute Module IO board (for CM and CM3) includes a connector for the screen, see: https://www.raspberrypi.org/documentation/hardware/computemodule/cmio-display.md

A TFT touch screen combines the fundamental elements of a raspberry pi touch screen with the advanced imagery TFT technology. These are the variants of raspberry pi touch screen displays that most consumers see and use on a daily basis. While TFT displays use more energy than standard monochrome LCD displays, many models provide brighter and more detailed visuals than conventional screens.
