Hello all, I am new to RPi and am working on a project where I want to use an LCD touch screen that I recovered from another device. I am struggling to figure out how to know which driver board I need to connect it to the RPi. I have the model number of the LCD which is LB080WV3-B1. I also was able to find the specifications of the panel from the manufacture which is located here: https://datasheetspdf.com/pdf/721772/LG/LB080WV3-B1/1

I don"t know what I am supposed to be looking for on the spec sheet to tell me which controller driver I can use. I have done a bunch of googling to try and figure it out but am more confused now than when I started. Can anyone offer any guidance or explain how to find the LCD controller that I need?

As it is an RGB interface you can directly connect it to the Raspberry DPI interface (https://www.raspberrypi.org/documentati ... /README.md) without "glue logic".So, what you will need is an adapter board which converts the 40pin GPIO (2.54mm pitch) interface to 0.5mm FFC. In addition you will need to input the timing (page 10) to let the RPI now how to drive the display.

This is what the above setup looks like "in action". That 5.6in display is 640x480pixels native resolution. I"m running KMS graphics driver which allows me to scale my desktop to 1024x768pixels which still has a good readability on the display (xrandr --output DPI-1 --primary --scale 1.6x1.6)

Thank you sooooo much for the detailed explanation!!!!! One follow up question, not sure what you mean by the "backlight inverter". The LCD has another two channel (red/black) wire sticking out of it that I am assuming is the power cable for the backlight. Is that what you are referring to? If yes, where is that supposed to be connected to on the RPI? or do I just need to connect it to an external power supply?

On 2-lane MIPI you can run 1280x800 pixels with ease, 3-lane is just enough (but tight) for 1920x1080pixels and 4-lane, well depends what you can get.

This is a 7in with 1280x800 pixels running happily (finally now) via MIPI interface from a CM4 (tested with 2- and 3-lane config, 4-lane would be nice for lowest EMI but fails)

Note: DSI to RGB chip used on the RPI display is EOL; so there is the chance that we will see a new official display in the future (but also a risk that RPi decided to make a last-time-buy with huge quantaties in orderto be able to ship longer).

this additional connector is the input to the CCFL backlight lamp. CCFL require high voltage to operate and the device which is used to drive them is usually called an inverter. Below is an example picture:

Simplest use of a DPI display is by adding the timing to `panel-simple.c", write an overlay which uses it, compile everything and then add the overlay to config.txt. No need to write any driver.

Connecting an LCD display to your Raspberry Pi is sure to take any project up a notch. They’re great for displaying sensor readings, songs or internet radio stations, and stuff from the web like tweets and stock quotes. Whatever you choose to display, LCDs are a simple and inexpensive way to do it.

In this tutorial, I’ll show you two different ways to connect an LCD to the Raspberry Pi with the GPIO pins. The first way I’ll show you is in 8 bit mode, which uses 10 GPIO pins. Then I’ll show you how to connect it in 4 bit mode, and that uses only 6 pins. After we get the LCD hooked up I’ll show you how to program it with C, using Gordon Henderson’s WiringPi LCD library.

I’ll show you how to print text to the display, clear the screen, position the text, and control the cursor. You’ll also see how to scroll text, create custom characters, print data from a sensor, and print the date, time and IP address of your Pi.

There’s another way to connect your LCD that uses only two wires, called I2C. To see how to do that, check out our tutorial How to Set Up an I2C LCD on the Raspberry Pi.

Most people probably want to connect their LCD in 4 bit mode since it uses less wires. But in case you’re interested, I’ll show you how to connect it in 8 bit mode as well.

In 8 bit mode, each command or character is sent to the LCD as a single byte (8 bits) of data. The byte travels in parallel over 8 data wires, with each bit travelling through it’s own wire. 8 bit mode has twice the bandwidth as 4 bit mode, which in theory translates to higher data transfer speed. The main downside to 8 bit mode is that it uses up a lot of GPIO pins.

In 4 bit mode, each byte of data is sent to the LCD in two sets of 4 bits, one after the other, in what are known as the upper bits and lower bits. Although 8 bit mode transfers data about twice as fast as 4 bit mode, it takes a longer time for the LCD driver to process each byte than it takes to transmit the byte. So in reality, there isn’t really a noticeable difference in speed between 4 bit mode and 8 bit mode.

If you’ve never worked with C programs on the Raspberry Pi, you may want to read our article How to Write and Run a C Program on the Raspberry Pi first. It will explain how to write, compile, and run C programs.

WiringPi is a C module that makes it easy to program the LCD. If you already have WiringPi installed on your Pi, you can skip this section. If not, follow the steps below to install it:

WiringPi has it’s own pin numbering system that’s different from the Broadcom (BCM) and RPi physical (BOARD) pin numbering systems. All of the programs below use the WiringPi pin numbers.

To use different pins to connect the LCD, change the pin numbers defined in lines 5 to 14. You’ll need to convert the WiringPi pin numbers to the physical pin numbers of the Raspberry Pi. See here for a diagram you can use to convert between the different numbering systems.

To use the LCD in 4 bit mode, we need to set the bit mode number to 4 in the initialization function (line 20 below). The following code prints “Hello, world!” to the screen in 4 bit mode:

By default, text is printed to the screen at the top row, second column. To change the position, use lcdPosition(lcd, COLUMN, ROW). On a 16×2 LCD, the rows are numbered from 0 to 1, and the columns are numbered from 0 to 15.

The function lcdClear(lcd) clears the screen and sets the cursor position at the top row, first column. This program prints “This is how you” for two seconds, clears the screen, then prints “clear the screen” for another two seconds:

Notice how the first string is printed to the top row, second column (the default position). Then after clearing the screen, the second string is printed to the top row, first column.

Each LCD character is a 5×8 array of pixels. You can create any pattern you want and display it on the LCD as a custom character. Up to 8 custom characters can be stored in the LCD memory at a time. This website has a nice visual way to generate the bit array used to define custom characters.

To print a single custom character, first define the character. For an example of this see lines 12 to 19 below. Then use the function lcdCharDef(lcd, 2, omega) to store the character in the LCD’s memory. The number 2 in this example is one of the 8 locations in the LCD’s character memory. The 8 locations are numbered 0-7. Then, print the character to the display with lcdPutchar(lcd, 2), where the number 2 is the character stored in memory location 2.

Here’s an example of using multiple custom characters that prints the Greek letters omega, pi, and mu, plus thermometer and water drop symbols for temperature and humidity:

As an example to show you how to display readings from a sensor, this program prints temperature and humidity readings to the LCD using a DHT11 temperature and humidity sensor. To see how to set up the DHT11 on the Raspberry Pi, see our article How to Set Up the DHT11 Humidity Sensor on the Raspberry Pi.

Hopefully this helped you get your LCD up and running on your Raspberry Pi. The programs above are just basic examples, so try combining them to create interesting effects and animations.

This repository contains all the code for interfacing with a 16x2 character I2C liquid-crystal display (LCD). This accompanies my Youtube tutorial: Raspberry Pi - Mini LCD Display Tutorial.

During the installation, pay attention to any messages about python and python3 usage, as they inform which version you should use to interface with the LCD driver. For example:

It is possible to define in CG RAM memory up to 8 custom characters. These characters can be prompted on LCD the same way as any characters from the characters table. Codes for the custom characters are unique and as follows:

This demo uses ping and nc (netcat) to monitor the network status of hosts and services, respectively. Hosts and services can be modified by editing their respective dictionaries:

exchangerate-api.com / free.currencyconverterapi.com: There are a lot of currency apis but these ones offer free currency exchange info. Both are used, one as main, the other as backup. Requires an API key to use.

In order to use the script, you need to get API key tokens for both exchange rate services and the weather api. Once you"ve done that, edit the script to put your tokens in the USER VARIABLES section.

The PWR will keep on and the ACT will keep blinking when the Raspberry Pi starts up successfully, in case both of the two LEDs keep on, it is possible that the image was burnt incorrectly OR the TF card was in bad contact.

This is a LCD display HAT for Raspberry Pi, 1.44inch diagonal, 128x128 pixels, with embedded controller, communicating via SPI interface. It also comes with three push button and a joystick, a good option as user interface panel for your Raspberry Pi Zero :)

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!

It’s capacitive touch- it senses your finger, but not pointy objects like a resitive screen. It works with stylii (styluses?) like the ones you might use with your iPad

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.

We’ve decided to keep the current design and orientation because it’s the best out of the two and the 10 degree difference in viewing angle is very slight. ( I use these screens every day ).

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 white screen, it probably means the screen’s ribbon cable isn’t seated properly. Make sure it’s pushed firmly into place and that the connector is closed properly.

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.

Be extremely careful when re-seating any ribbon cables, the retaining clips can be fragile. If you have a pre-assembled screen then the main ribbon cable is probably fine.

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

One of the most awaited plugins for Volumio is finall here: the touchscreen plugin. With it you can easily show the gorgeous Volumio UI on any display, included the official Raspberry PI Display, available on our Shop. Let’s see how to easily achieve a fantastic touchscreen for your favourite music player in less than 10 minutes. This tutorial will explain how to connect the Raspberry PI display and enable the Volumio UI with the plugin.

Assuming you’ve already downloaded and flashed Volumio to your Raspberry PI (we suggest to use the newest  Raspberry PI 3), the first step is the wiring:First, let’s attach the ribbon cable going from the Raspberry PI Display to the PI itself. On the Raspberry PI Side, make sure the blue part of the ribbon cable is facing outwards. Your final goal should look like this:

You’ll have 4 coloured cables to connect too. They are 5v, GND, SDA and SCL. You can look at the below image to identify the proper pin on the Pi itself.

Notoriously, feeding your PI with an adequate Power Supply is mandatory to have a reliable system. That’s especially true when we connect a power-hungry device like the Raspberry PI Display. Luckily, there’s a way to understand if your PSU is good enough: just power on your pi and observe the screen, if you see a coloured square on the top-right side of the screen, it means that power to your PI is not enough. Don’t you see it? Then all is good.

That’s the easy one. Just connect to Volumio’s WebUi as you would usually do, and navigate to the Plugins page from the settings menu. In Miscellanea category, you’ll find the Touchscreen plugin. Just click install, nothing more. PLEASE NOTE: The touchscreen plugin is compatible with volumio version from 2.001 onwards

I must admit that altough this display is not particularly brilliant when it comes to resolution and colour accuracy, it looks indeed very nice with Volumio’s UI. Also, usability is very good on the Raspberry PI 3 and the UI runs smoothly also with big libraries… So, folks, enjoy!

If you don’t have a Raspberry PI, or you’re simply looking for alternatives to the Official Raspberry PI Display, there are at least two extra options for you:

The Odroid display is not only a viable alternative, it also have several advantages over its PI counterpart:Since it takes power from USB and video signal from HDMI, it can be used virtually with any Computer with an HDMI output, not just the Odroid or the Raspberry PI.

UPDATE: Lot of time since I published the original article. The Odroid 7” does not seem to work properly with Raspberry PI (not tested with the Odroid). So, if you’re looking for a display for the Raspberry PI, get the official one.

The Waveshare 7” display has become rapidly a widely adopted display, thanks to its cheap price. However this particular touchscreen has shown several reliability issues (altough this seems fixed in latest models, thanks to a firmware update), it requires a particular touchscreen driver which is not always included in major distros and its colour reproduction is not the best.

Here we are folks! Hope you found this article helpful, you can share via comment below how you use your Volumio’s touchscreen setup and if there are other display alternatives!

So we had these two dead Dells with lovely, flawless 15.6 inch full HD, low-power screens in the loft, waiting to be targeted for termination. I’d wondered for a while about getting a driver board and seeing if I could re-use them. But back in October 2015 I actually did it. As soon as I’d made it work for one, I ordered a second board, with the intention of making a video about it.

The driver board I bought came from Ali Express. It’s no longer available, but I’m sure you could find one if you wanted to. In any case, your LCD will probably be a different part number.

Lots of people throw away dead laptops now, but often the screens are perfectly fine. If you want to bag yourself a gorgeous screen for your Raspberry Pi, DSLR, Video camera or any other computer I’d recommend you give it a shot. Do be aware that you are not guaranteed a result (that’s why I bought one driver board first, then another when I knew it worked).

This is something I did that brought me a lot of pleasure and I regularly use one of these in my workshop as a video monitor and with Raspberry Pi. So I thought I’d share it with the world. If it works out for you, you can really get an awful lot of screen for your money. Certainly more than any screen you can buy new.

Also, be aware that you will have to either sort out your own case or frame for it. For us hacker types that can often be a plus rather than a minus. I just kept the really useful mounting frame on the LCD and hung it from a shelf at the perfect height for my use.
