dsi lcd panel raspberry pi quotation

A resolution to the test screens that occur during reboot has been released as an app note. The app note can be found in the documents section of the product page here: https://www.crystalfontz.com/product/cfam800480b0050tc-800x480-raspberry-pi-dsi-tft-lcd

*For applications where the controller will be shut down or reset, an additional connection to the reset (RST) pin on the J3 header is required, and must be toggled during boot-up.

**Some versions of Raspbian the creators have inverted the display which can cause the touch screen to not track the same with the image. To fix this, add lcd_rotate = 2 to the config.txt

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 7" TFT touch screen display with a resolution of 800 x 480 and capacitive touch is perfect for your Raspberry Pi boards. With a DSI interface, true color display, easy installation, and space-saving design, it is a perfect touch screen monitor for your DIY and on-the-go projects! What we like about this screen is the DSI cable provides the path for BOTH the POWER and DATA (graphic and touch sensor), no additional wiring is needed! And NO DRIVER installation is necessary! Super neat and easy to use.

We recommend adding the 5mm PCB spacer before mounting the Raspberry Pi board to increase the space between the LCD. This will also help in handling the microSD card.

A 4.3 inch DSI touchscreen for the Raspberry Pi. Connect the screen to your Raspberry Pi via the included DSI cable and the screen works immediately, no software or customization is required.

This is a 5" Raspberry Pi LCD touchscreen with 800x480 resolution and 108×64.8mm display area. The product supports the Raspberry Pi DSI display interface and comes with a capacitive touch panel on its screen and supports 5 touch points.

The special holes design on the back of the screen is convenient to directly install the Raspberry Pi in the product. There is no need to provide external power for the touchscreen as the Raspberry Pi power supply is adopted. In addition, the screen supports hardware backlight adjustment. The function can be realized by turning the potentiometer on the back of the display.

CONS: low refresh rate & resolution, supports Raspberry Pi only, requires Raspberry Pi 40PIN GPIO (the SPI bus), poor compatibility with Raspberry Pi system.

PROS: high refresh rate, multiple resolution support, multiple devices support, leaves the Raspberry Pi 40PIN GPIO free, better compatibility with Raspberry Pi system.

Has anybody succeeded finding a working solution for a larger (15 inch or larger) display that will work with the DSI on-board interface connector? Big enough to use comfortably as a programmers display (with older eyes) and not having to buy an expensive monitor. I get why 7 inch works for IoT and "toys". I want something that can be super portable and put in my own design housing. I have found companies (Chinese primarily) that sell the screens and even controller boards, but nothing that mentions DSI. Anybody know of a solution that would "glue" the DSI to an LVDS interface such as you would find in a scavenged laptop display, for instance?

Given that the DSI connector is effectively a proprietary connector for the official Raspberry Pi display, the best you"re going to get is probably something like this:

The peripheral in the SoC is a proprietary implementation, but even that is only half the battle as you then need to sort any additional GPIOs and config options to actually get something on the screen.

So...if price is the issue, hunt around for a used or even a manufacturer reconditioned display. It"s going to far, far less than a 15" or larger display that will work with the DSI connector. Indeed, you could get a display larger than 15" NEW that would be less that such a beast.

For theater lighting it is nice to have two screens. The QLC+ runs on the DSI screen and it controls the omxplayer for streaming video to a projector to light up the background of the stage.

The only practical problem is that there is two pop-ups in QLC+ that are too high for the 7" display (800 x 480). A little more pixels for the height or a custom compiled version with lower popups would be nice.

I just got my lovely SmartiPi Touch enclosure from the Kickstarter project. Here is the theater screens on the 7" DSI display. Actually they are nice and usable already :)

The latest Jessie based QLC+ is run here on Raspberry Pi 3. The serial port is still not working properly but I am sure that within a day or two we will figure out the right dt blobs to make it work on RPi 3 also.

We have considered the RP3 for rural schools for many reasons but it is obtaining a suitable supply of monitors at a reasonable cost that prevents us doing this. The cost of obtaining, shipping and transport to a rual school of a monitor is the same as shipping a complete donated PC from halfway around the world!

The Waveshare display I received required about the same amount of assembly as the official Raspberry Pi 7" display, i.e. a ribbon cable to connect and some mounting pillars...

The AdaFruit people have the "Kippah" that adds regular LVDS panel support, and it works well, but you lose pretty much all peripherals (UART, I2C, and so on.) Especially losing the I2C for an RTC hurts; not having the UART comes second place.

As its connectivity indicates (DSI, not HDMI), this Raspberry Pi compatible display is a touch screen. It has a tempered glass panel that can manage five points of contact simultaneously (e.g. the 5 fingers of a hand).

The Raspberry Pi capacitive screen offers a resolution of 800 x 480, which is sufficiently fine for your eyes not to be able to distinguish the pixels. It’s an essential accessory for developing touch control for a robot, for example, or for displaying video games developed on RetroPie or viewing images from a surveillance system terminal.

The official 7 inch DSI Raspberry Pi screen is now launched and available for purchase. It’s been a long time in the making, but the B+, the A+ and Pi2B have all been responsible for pushing this display to the back-burner.

It’s going to retail for around £50, depending on where you buy it. The official headline price is $60 + shipping and local taxes. For a long time I’ve thought it would be awesome if there was a decent screen available for the Pi at the £50 price point. Now there is.

It has capacitive, 10-finger touch. This will be most useful in applications where people want to create their own graphical user interface (GUI). It will enable the Pi to be used for controlling all manner of systems with no need for keyboard or other interface peripherals. Touch works in LXDE if you update/upgrade on the latest Raspbian.

Because it uses the Pi’s DSI connector, you can still drive another display from the same Pi at the same time. This can be either composite or HDMI. You’ll see a demo of this in the video.

As long as you are using a decent power supply and connector lead(s) you can run a Raspberry Pi and the DSI screen from just one supply. You can power the Pi via GPIO jumper leads, the USB power port on the driver board, or separately.

And someone’s bound to find a creative way to slim it down and hack it into a tablet. With a Pi2B on the back, the total depth is 3.5cm, which is a bit ‘tubby’.

From measurements I’ve made, if you’re willing to butcher away the USB power port, you could potentially position the Pi 7mm closer to the board. You could also save another ~6mm by using an A+ instead of a Pi2. (The highest point on A+ is the GPIO pins – you could potentially shave another 2mm there.) So, in theory, you could save 1.5cm of that depth with some butchery. There may well be other creative solutions using longer ribbon cables and placing the Pi next to the driver board. It’ll be interesting to see what people come up with.

Yes. It needs something to mount it to. A case, a box, a panel or some sort of stand is going to be necessary for most applications or we’ll see broken bezels before long. There are four threaded mount holes on the LCD back. You could also use an adhesive to glue the bezel into some kind of panel.

Pimoroni have designed a lovely perspex layer case with integral stand that will be available to purchase from them separately. It’s £10 including VAT, and is available in Noir, Flotilla Blue, Tangerine, Coupé Red and Green.

As long as you’ve allocated 128 Mb RAM to GPU, dual-screen use is flawless. I plugged in my 23″ Samsung HDMI TV and sent a video through HDMI with omxplayer --display 5 filename.mov This then played flawlessly while I messed around using the camera module on the DSI display. I had it showing live camera video output and also made it wrap live video round a spinning 3d teapot to try and stress the GPU. Neither display skipped a beat. You can see that in the video.

No. I measured the display’s power usage with my Emeter while powering the Pi separately. The display used 2.23 Watts. (0.43 A at 5.19 V). A Pi 2 model B uses about 1.5 Watts, so this would give you a system using ~3.75 Watts altogether.

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/

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
