This was easy to install and it looks good. The Touchscreen is responsive and clear, but you might want to use a stylus. The only issue i had is finding a case for it. You"ll want to get one right away, unless you have a 3D printer to make one yourself. The screen is really thin, so I didn"t want to carry it around without some protection. Overall, it"s a great touchscreen, especially for the price, and I like that it is Raspi-branded.

This screen worked right out of the box! Touch worked great with my new pi 3! However aside how fragile the (non functional) edges are, the only real issue I see is upon shutdown of the pi... The screen goes through a series of screen washes/whiteouts and never really shuts off.. I have to pull power to get it to turn off.. I"ve even tried usb/provided jumper wires.. And both results in the same thing. Not sure if this an issue per se, but it is bothersome.. I can just turn the unit off, I need to unplug it too..

I"m using it to run a lighting and irrigation system for my house. The color graphical interface allows me to use BMP images of my house and yard for control screens, and its built into an enclosure set into the wall for a slick professional look. I even put an access from the backside of the wall for wiring it without having to remove the Pi or the touchscreen.

I purchased 5 touchscreen. Two before and three in January. Touch and display quality is superb. After two-three month of use (no rough use; handled with care), display LCD and front touchpanel (black bezel) break apart. They both are connected using a thin double sided tape. I was planning to use in industrial environment but after such issue, I dropped my plan to use it in industrial environment.

Five of two displays are not in good condition. First display"s touch-panel and display LCD was break apart after two-three month. The second among five displays had another issue. Display LCD was mounted slightly right side of the touchpanel. Once you power-up display, it is easily be seen that LCD panel was a bit off-side. The other display"s screen guard having so many scratches on them which seems mishandling.

I am using Raspberry Pi 3. The display came up with no problems. I am just waiting for the Smarti Pi Touch enclosure (pre-ordered after the Kickstarter project closed) before continuing to work with it.

The only question(s) that I have are regarding what sort of additional processor power is inside the screen, and whether powering it from the micro-usb connection whilst also bridged from the RPi3 is an issue (it hasn"t hurt anything, yet!).

I WAS DISAPOINTED THAT THE UNIT DISPLAYS EVERYTHING UPSIDE DOWN. I HAD TO USE THE LCD_ROTATE=2 COMMAND IN CONFIG.TXT TO FIX IT. THE INITIAL BOOT IS STILL UPSIDE DOWN BUT I GUESS AFTER IT READ THE CONFIG.TXT, IT FLIPS. SHOULDN"T IT COME STANDARD RIGHT SIDE UP?

The must annoying feature is the bright white screen when it loses signal as the OS shuts down. The touch input is inconsistent as input. I was using the I2C for a device was not able to get it going on the alternate I2C, but fortunately the required clock and data are on the DSI cable ... wasted hours finding that out. An OLED display, higher res, and lower current draw would be really nice in the next version.

I forgot to check that this LCD touchscreen don"t have a case. Much better that you have a notification (e.g. recommending the user to purchase also a case) when purchasing this kind of product. But thank you for this product, I will purchase again soon.

The only minor drawback that everyone should be aware (which is to be expected, honestly) is that the display draws quite a noticeable amount of current. The SmartiPi case comes with an splitter USB cable for the power source, but if you expect to use that, be prepared with a (very) beefy power supply, else you"ll get the thunder icon on the screen all the time and a very reduced performance (Just discovered that the RPi3 reduces its own clock when power is low).

I currently power this with a separate 1.5Amp supply for the screen and a 2Amp supply for the RPi3 and everything works just nice. This totals to a whopping 3.5A, which may be overkill, but keep that in mind as a reference.

I am impressed with this screen, I also got the mating case (SmartPi Touch) and it assembled nicely. With the separate case, the included jumpers and cable are not needed. The PCB was already attached with the standoffs. The packaging was super! The screen is slightly larger than 7 inches. I measured it as 7 5/8" wide X 4 3/8 high with a diagonal measurement of 8 9/16.

Works very well, but I haven"t found reliable instructions. Internet search turns up lots of hits, mostly unreliable. Doesn"t work with the OSMC I have, and I haven"t had time to track down the problem. Didn"t find anything in the official blogs.

This official Raspberry Pi 7" touchscreens now come with the display controller already connected and mounted to the back of the display. You still need to be careful pulling forward the small black tab ends that connect a ribbon cable to the RPi.

I bought the companion enclosure as well. This Touchscreen works exactly as described. I am very pleased with the display. I ended up using a mouse anyway as the icons (while clear are very tiny) and selection areas are a bit small for fat fingers.

I connected it to a Raspberry Pi 3 B running Stretch and it seems to be working perfectly. I had been previously driving a VGA monitor from HDMI through an adapter. The RPI 7" screen started up just fine without changing or installing anything with the OS.

Based on other comments here and looking at one of these at a maker space, I bought the smartipi touch case for this; it"s strongly constructed and works great. Only issue was that I"m using this with a model 3 B+, and that takes a different door on the back than comes with the case (this is being fixed by the smartipi folks, but I don"t know the logistics of getting their new cases into Sparkfun)

I have tried other touch screens for the Raspberry Pi. They had complicated assembly and were very difficult to get them to work. This unit was easy to install and get working, is very nice looking. I am very Happy with it.

Right out of the box it worked. Didn"t even have to do anything to the RPi (in fact, both were taken out of the box at the same time, connected, and worked on the first power up). Screen quality is good for price. Also ordered the "SmartPi Touch" case which holds everything together very nicely.

Ordered it, a Raspberry Pi 3 B+, and a power supply. (Had a mouse, keyboard, and uSD on hand.). It came a couple of days ago, and I put together yesterday. Had noticed in the documentation that there"s a micro USB power input, and a standard USB output. In the configuration where the power supply is plugged directly into the Pi and the LCD interface is powered via a USB cable plugged into one of the Pi"s USB ports to the LCD"s micro USB, the LCD won"t light up at all. When the power supply is plugged into the LCD controller board and the USB cable connects power to the Pi, I get "low voltage" warnings (yellow "lightning bold"). When I use the provided F/F jumpers, it works fine, but this will cause problems plugging in other "hats", as well as clearance problems. (In my application, separate power supplies would be a BIG PROBLEM.) BTW, I checked with two different USB cables, and got the same problems as well as when I tried an Adafruit 5.25V power supply. (I was about to try a second RPi3B+ when the original one stopped booting. Fortunately I had another that I"d been using as a "pass-around" sample at talks, and fortunately when I tried it, it still worked, so now the "dead" one will be passed around!) Also, it could prove really useful to know what size those mounting screws are in case they get lost! Ace Hardware recently opened a new store about half a mile from my house!

The screen is portable enough to take with you and the Pi will use it with no configuration change when it"s powered up. Used it to set up several Raspberry Pis in a remote lab. Touch screen is nice but bring along a keyboard if you have to do any setup work. One thing to make it better, replace the jumper wires with a ribbon cable connected to 1x5 and 2x2 pin headers.

I have a Raspberry Pi in each room of my home and they run a Kiosk interface for home automation, cameras and more. I"ve tried some cheaper ones and none have survived. (I"m hard on equipment) I haven"t managed to break one of these yet.

Got a PI3+, 7" touchscreen and SmartPI case for manufacture test. I put these together and booted the latest Raspbian. The LCD and touchscreen connect to the display connector using a short FPC cable. The display booted and the touch screen just worked out of the box. There were some nice but not well documented improvements. They provide a Y USB cable to power both the PI and the LCD. This is a cleaner solution than the jumper wires they provide.I"m not a big fan of using lego blocks in a industrial environment but the case went together easily and does a decent job of protecting the display and the PI. Some reported a inverted display issue but that seems to have been resolved.

A truly plug-and-play display for the Raspberry Pi. Does not steal any additional extension connector pins if you power it with a USB power supply and leaves the I2C1 interface available for other devices.

Big enough for somewhat squinting actual Raspberry PI development and computer work, but really shines for touch screen optimized large button control panels.

You can just install a Pi3 or 4 on the back, but with a 4 you really need some additional airflow. The SmartiPi Touch 2 enclosure works better. https://www.sparkfun.com/products/16302

It works fine, no glitches, no problems, no hair pulling moments. Once electrically connected to my RPi 3B+ it"s good to go. I run it with the "lite" version of the Raspberry Pi OS with only xorg drivers installed, no full desktop or windows manager, as part of an in-the-field project with a HQ camera attached. My only complaint is the ribbon cable could stand to be about 6 inches longer.

It works great, the colors are beautiful, and finger touch works fine. What I like most is that the Raspberry Pi GPIO pins are all still available - except for one +5v pin and one Ground pin. Both are redundant (i.e. others are available). So, this is not an issue at all. I also like that data connects to the Pi via the IPS ribbon cable. Another thing I like is that power connects to the Pi via two jumper wires. The Pi is fussy about its power supply voltage. So, the jumper wires are better because they are heavier gouge than a small PCB trace.

I connect a Pi v4 and put the whole thing in the SmartPI Touch 2 case from Sparkfun and now it looks pretty professional. Make sure you use a good power supply.

Where is the documentation? This thing is so poorly documented it"s almost a joke. The whole point of the RPi ecosystem is to enable Makers and learning about electronics, so why isn"t this fully documented?

I used this to build a portable utility/testing device for my company. It works fantastic with the SmartiPi Touch Pro Case on Amazon. The touchscreen functions great, only thing is you can"t register mousedown and mouseup events in Chromium (only click). Other than that it"s great!

I got a couple of these for several RPi projects that Im developing and they are working amazingly well for the application. If these fit your application needs I wouldn"t hesitate to recommend them.

And it does "blank" the display but the "backlight" is still on. Is there any way to actually turn it off currently, without turning off the whole thing?

Should I consider that the lack of any answer here, means that the backlight cannot be turned off? If I make an external circuit to cut the USB input power while it is still connected to a running Pi, will that hurt anything? What would I need to do to reinitialize after powering it back up?

Thanks Dom, that"s some useful info... so I gather the I2C register setup for the LCD display is inside some function that is not in any way accessible from userspace (apart from doing a reboot)?

The PWM controls and the power on/off controls are hidden away in a little Atmel which has to be controlled from the GPU side (it has to be this way because we share that I2C bus with the camera). Currently there is an "in-memory" communication scheme between the GPU and the ARM for the touchscreen but I"ve not yet implemented the controls for the PWM and power

My interest is in minimizing power draw when the display is not in active use. So if I can turn the backlight PWM down to 0 and then the current draw for everything else is relatively small compared with the Pi itself, that"s fine. If I need to save more power than that, I"d have to shutdown the Pi anyway and do a normal reboot to get it working again.

I want to use the device as a home automation controller, and having it on all of the time takes too much power and will shorten the life of the display.

I too am looking for the same functionality. I would like to turn on the display with a PIR motion sensor and then have it time out after a certain amount of time with no activity. ( home automation system as well ) ...

I must be missing something really obvious. Is there not a way to automatically disable the backlight after a fixed period of time. The screen turns black after a certain period. I would like the backlight to turn off too.

As @dataworm suggested use "sudo rpi-update" to update the firmware. Normally you avoid that command, since it could cause problems, but you"ll need to do it for the display backlight function. After running "rpi-update" you will see all the backlight folders have been added and you can then change the value in "bl_power".

Raspberry Pi OS provides touchscreen drivers with support for ten-finger touch and an on-screen keyboard, giving you full functionality without the need to connect a keyboard or mouse.

The 800 x 480 display connects to Raspberry Pi via an adapter board that handles power and signal conversion. Only two connections to your Raspberry Pi are required: power from the GPIO port, and a ribbon cable that connects to the DSI port on all Raspberry Pi computers except for the Raspberry Pi Zero line.

The resolution of the LCD display is 800 x 480, you can configure the resolution via software, and the maximum resolution it supports is 1920 x 1080. It is a USB capacitive touch screen and does not require a driver. It supports five touch control, besides that, the LCD screen comes with an OSD menu adjustment function. You can adjust the contrast, brightness, and switch button. There are 9 interfaces on the back of the screen, one earphone for audio output; two touches (USB connector), for power supply and touch output; one display, an HDMI interface, for connecting the motherboard and LCD display. One power, it can control the backlight to turn on and turn off to save power. One return, it’s only useful in the OSD menu. One right/down, backlight shortcut key. One left/up, backlight shortcut key. A menu, it’s useful in the OSD setting menu, open the OSD/ select key.

When you want to have an easier time of connecting to different media and selecting it, a single-board computer is an efficient option. The Raspberry Pi single-board computers work with a variety of peripheral devices, including LCD display modules with touchscreens. On eBay, you can find a variety of sizes and features of affordable Raspberry Pi touch screen units to pair with the single-board computer for enjoying your favorite media.What are some features of Raspberry Pi Touch Screen modules?

Automatic power off: If the touchscreen is not used within 10 minutes, it automatically powers off. This time can be adjusted to turn off in less or more time.

Signal support: It accepts EGA, SVGA, WXGA, VGA, SXGA, and UXGA video signals from the computer.What are the sizes of Raspberry Pi touch screen modules?

The Raspberry Pi touch screen modules are available in sizes of three to seven inches when measured on the diagonal. Their frames can be set up in a vertical or horizontal orientation for viewing in a portrait or landscape setup. The stands for the touchscreens can also be angled for easier use and viewing. See the manufacturer site for details.What is the compatibility of a Raspberry Pi display module?

The following are compatibility options for a Raspberry Pi touch screen display module:USB: They can display the information that is stored on a removable USB drive plugged into the Raspberry Pi computer.

Consider the following features when you are shopping on eBay for a new or used Raspberry Pi touch screen:With computer case: Some have a case for holding both the computer and the display in one unit.

The official Raspberry Pi 7” Touchscreen allows you to add touch inputs to your programs, creating a new way to interact with your projects. It also makes for a fantastic desktop screen for day-to-day use of your Raspberry Pi. Wrap it in one of our screen cases and take it anywhere – events, Raspberry Jams or even just your friends house for a coding evening!

For smaller projects, LCD and ePaper displays are a fun way to add a visual element to your projects. With simple code and wiring, they’re great for projects that require text, menus and navigation.

There is an official 7-inch touchscreen module for the Raspberry Pi: After testing it under different applications for some time and also putting together a FAQ thread, in this article I summarized my impressions and the advantages and disadvantages of the display.

With its 7 inches, the display is in a good range – big enough to handle GUI applications, but still power-efficient (350-390mA at 5V). What I liked very much is that everything has worked without complicated driver loading and initialization. At first, I was sceptical because no calibration was needed, but as it turned out, touch detection is amazingly accurate, even more accurate than my resistive touchscreen with calibration.

I was also amazed with, in my opinion, low resolution of 800×480 pixels. Since 720p and partially FullHD videos are playable on the Pi, I would have expected more here, but in practice, this had less impact than I suspected. Now that I have tested the display for some time (and possibly got used to the resolution), I find it is not as annoying as initially assumed. On the other hand, this has probably also been sacrificed to the price – the Raspberry Pi Foundation manufactures devices that are as affordable as possible, sometimes compromising (such as the Raspberry Pi Zero).

In comparison, partially similar displays cost a little less, but almost all of them have no capacitive touch. In addition, all other displays occupy many GPIOs and/or the HDMI connection. With the official 7″ display it is possible to connect another display.

Anyone who plays with the idea or has already bought such a display, most likely already has a project in mind, for which he wants to use it. I especially like the display for the following projects:

I’ve been thinking for a while about building a CarPC, but so far I was been sceptical, especially because of the displays. First of all, most other good 7″ touchscreens, which are compatible, need at least 12V. I plan to build a module that can either be powered by a cigarette lighter USB or built into the radio slot. Well, with this display, I will probably implement a car PC in the near future.

The previous places of use for my display were as a panel for my radio-controlled sockets, surveillance camera, infrared barriers, etc. For this, I have written a GUI with Python, which accepts my input and executes appropriate commands/scripts (GUI tutorial will follow soon). So that the display does not draw power constantly, I have put a motion detector over it, whereby the display is switched on as soon as someone approaches the panel.

Another interesting project, which was found is the Raspberry Pi as a tablet. For this, you can download a 3D model and print it with a 3D printer. In addition, you need a flex cable, a PowerBoost and a Li-Polymer battery.

As mentioned earlier, the touchscreen has some very positive aspects, but also some that speak against the display, which I will briefly summarize so that everyone can decide for themselves if this display is suitable for their own projects and ideas:

For some of my applications, the DSI cable was too short, but luckily a longer (50cm) can be purchased or e.g. the longer ribbon cable of the Raspberry Pi camera module can be used.

I suppose that in the future more applications will appear for the Pi which makes use of the 10-finger touch and thereby also it should be easier to find answers to certain problems of the display, than previously, where one had to be lucky to find support for exactly his touchscreen model.

The 7” Touchscreen Monitor for Raspberry Pi gives users the ability to create all-in-one, integrated projects such as tablets, infotainment systems and embedded projects.

The 800 x 480 display connects via an adapter board which 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 Raspberry Pi OS for full functionality without a physical keyboard or mouse.

Make your own ‘Internet of Things’ (IoT) 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.

Update:As of October 2015 the touchscreen is now supported on the Model B and A Raspberry Pi in Raspbian. You"ll just need to add jumpers from SDA1 and SCL1 on the Pi to SDA and SCL on the display board and to add "ignore_lcd=0" to /boot/config.txt to be up and running!

This is the 3.5inch display for raspberry pi, support HDMI input, refresh rate of 60FPS or more. It has a physical resolution 480x320, configurable software resolution up to 1920x1080.  It can be used as raspberry pi touchscreen with touch control function (need to install touch drive). It also can be used as a computer monitor, TV box, PSP and other standard HDMI output device (without touch function). The 3.5 inch display module is compatible and can be inserted directly into all versions of raspberry pi board (raspberry pi, 1 generation B and Zero, HDMI line).

A common question we came across when building Screenly is how to manage the display’s power. When we first started out, we thought that this topic would be a trivial matter. It turned out to be anything but trivial.

Of course, different monitors behave very differently. What we discovered was that while most monitors would turn off just fine, many monitors ended up either not waking up at all or, alternatively, waking up in the wrong resolution.

This is why we still do not officially support turning monitors on or off with Screenly’s paid version. If you are running Screenly Open Source Edition (OSE) however, you are free to experiment with what works with your screen.

Let’s dive into how you can do power management on your display in Screenly OSE. The three tools that are relevant for this task are vcgencmd, tvservice and cec-client.

If you are lucky, your monitor will work well with vcgencmd. All this method does is toggle the power status of the HDMI port. This method will usually turn off the monitor, as most monitors will automatically go down in sleep mode if the HDMI signal is turned off.

However, beware that some monitors will switch to the another input when they wake up. Hence, if you have another active input, chances are the monitor will switch to that new input instead of turning off.

If your monitor turned off and on again with these commands, then congratulations. You can skip to “Automating the power management”. If not, carry on.

Another alternative is to use tvservice. Please note however that this tool often works for turning off the screen, but struggles with getting the monitor back into the right resolution.

Once you have figured out how to turn your monitor off and on, it is time to automate the process. The easiest way to do this is to use a cronjob to schedule this. (If you are not familiar with cronjobs, you can find a quick tutorial here. Use Cronjob wizard to generate a cronjob.)

For instance, if we want to turn off our monitor using vcgencmd at 8PM and turn it back on at 7AM on weekdays, we would create two cronjobs like this:
