What do you need to get started with a Raspberry Pi? Well, you might claim that you’ll only need a power adapter and a micro SD card to unleash the potential of the Pi. However, if you are among the majority of the users who use this as a compact computer, you will always need a screen to monitor what your Pi is doing and interact with it instead of using SSH. So what kind of screens will match the credit-card-size Raspberry Pi? The answer from UCTRONICS is simple: you need a portable screen for a portable computer!

UCTRONICS released pocket size 3.5" screens for the Raspberry Pi several years ago, and it was quite a success for us. The compact 3.5" display perfectly matches the form factor of the Pi itself and seems really integrated. When we were designing that touchscreen, we were thinking of building an alternative to the official display with the MIPI DSI connector, but starting with a lower-end model so that users have easier access to a small screen specifically made for Pi. We did it, and you can achieve most of what you will expect from the official display at a third of the price, and with its smaller size, you can bring your all-in-one Raspberry Pi Project outdoor more easily. Does this product seem promising enough for us to stick to it? The answer is NO.

Where does this tiny screen fall short? There are at least three factors that handicap this product. The first huge shock is from the Raspberry Pi 4, which has switched to a Micro-HDMI connector and rules a lot of the well-integrated compact HDMI screen out of the market, including ours. You may be lucky enough to survive this with the official touch display, but the Pi 4 almost sets a new starting point for all accessories and peripherals with the hardware changes and updates. The second is the touchscreen driver issues. That screen uses SPI for driver controller, and we’ve only offered the touchscreen support on the Raspbian, which drives away quite a lot of retro gamers who use the RetroPie system for portable retro gaming. The third one is the viewing area because some people expect larger fonts and icons, but that is hard for a 3.5” screen.

Now that the 3.5-inch screens do not work correctly with the newest RasPi, UCTRONICS has released the new 5" and 7" sizes with the micro-HDMI to HDMI adapter cable and USB touch controller for the Pi 4. Those screens might not be so pocket-sized anymore, but it’s still portable enough to hold in hand.

The new UCTRONICS touchscreens are competitive enough with the IPS display panel, the HDMI connector with micro-HDMI adapter, and the USB touch controller.

IPS is short for In-Plane Switching, and it’s a widely adopted display technology based on TFT. So, what will the IPS display bring to users? In a word, it’s thin with a wide viewing angle. The 178-degree viewing angle on our new screens will decrease the color degrading when viewed from a larger angle.

The HDMI is a mainstream video/audio connector and used in a lot of devices. The HDMI connectors on our screens mean that you can quickly connect them to Windows computers and laptops, or even game consoles like PlayStation and Xbox. The micro-HDMI to HDMI connector also ensures that Pi 4 users can have fun with them.

Compared to our previous screens that use the SPI for touch controller, those with USB touch controllers provide universal compatibility, and you can connect the USB cable to the target video device to add touchscreen support, whether it’s a windows device or even a Samsung smartphone, let alone the Raspberry Pi 4.

Sometimes the users want more than just a small screen that displays things, and our screens also have more to offer. These UCTRONICS screens come with 5-finger touch support, and the small micro-HDMI adapter makes sure that you still have access to another micro-HDMI port on the Pi 4, so you can still have dual monitors with our display connected. Aside from the Raspberry Pi, they also work as a general-purpose touch screen for other HDMI devices.

Aside from that, sometimes you want the displayed image upside down but don"t want to toggle the Raspbian config file, so our 7" inch display offers a rotation button, and you can use the onboard rotation button to rotate the screen to what you prefer.

In order to meet the increasing need of compact HDMI displays, especially for some popular single-board computers like the Raspberry Pi, the UCTRONICS team now releases a 7-inch HDMI LCD display with capacitive multi-touch touchscreen.

The UCTRONICS 3.5 Inch touch screen is the same size as the standard Raspberry Pi model B/B+, and well-mates with the Raspberry Pi boards. With a tiny size, vivid image, and responsive touchscreen, it is definitely ideal for portable devices and multimedia projects. It is a great replacement for a heavy and bulky HDMI monitor, keyboard, and mouse

Step1: Align the pin 1 of the edge connector between the LCD display and Raspberry pi board, connect the pin 1,2,3,4 then pin 19,20,21,22,23,24,25,26.

Attention: If you want to use the touch function, you need to download and install the driver manually refers to the instructions we provided. The driver includes the settings of the Raspbian OS resolution and touch screen support.

Attention: If you use this display without a Pi, the touch function is not available because the touch function of this display just supports the Raspbian system. Meanwhile, an extra HDMI cable also is required for the video transmission.

UCTRONICS U6111 is a 3.5” TFT LCD display with SPI interface and touchscreen support. It works with all standard Raspberry Pi models and supports operating systems like Raspbian, Ubuntu, Kali and RetroPie. Windows 10 IoT is NOT supported.

In order to meet the increasing need of compact HDMI displays, especially for some popular single-board computers like the Raspberry Pi, the UCTRONICS team now releases a 5-inch HDMI LCD display with capacitive multi-touch touchscreen

UCTRONICS 3.5 inch TFT LCD display module is designed for Raspberry Pi zero/Pi 2 /Pi 3 Model B / B+ /Pi 3 B+, and can also be used on other hardware platforms with an SPI interface. The 3.5" inch screen is in the same size as the standard Raspberry Pi model B/B+, and well mates with the Raspberry Pi boards. With its touchscreen, it is suitable for portable devices and projects. It is also a replacement for a heavy and bulky HDMI monitor, keyboard and mouse.

In the previous article, I described the steps needed to install an LCD touchscreen on the Raspberry Pi. In this article, I will show you how to adjust the screen rotation of the LCD to landscape mode, and will show you how to calibrate the touchscreen pointer for optimal accuracy. Just follow the steps below to compete the process of setting up your Raspberry Pi LCD touchscreen:

1. First we need to change the setting for screen rotation in the /boot/cmdline.txt file. This setting is called fbtft_device.rotate=X. By default, this is set to X=0, which results in a portrait mode screen orientation. In order to switch the orientation to landscape mode, change fbtft_device.rotate=0 to fbtft_device.rotate=90. Enter sudo nano /boot/cmdline.txt at the command prompt. There should only be one line in this file. Go to the end of it and you will find the fbtft_device.rotate=X setting. Change the value from 0 to 90:

However, if you try to touch the screen now, you will find that the pointer movement does not correspond to your finger movement. This is because the LCD screen driver and the touchscreen controller driver have separate settings for screen rotation. We need to change the rotation of the touchscreen controller driver to match the rotation of the LCD screen driver.

2. You probably noticed that dragging your finger to the right moves the pointer up, not to the right. This indicates that the x and y axes of the touchscreen are swapped. To correct this, we need to swap the x axis for the y axis. This can be done by changing the swap_xy=X parameter in /etc/modules.

Now if you drag your finger around the screen, you will notice that the y axis (up and down) is correctly aligned with the motion of your finger. However, the x axis (left and right) is still inverted. To fix this, we need to install two more kernel modules, xinput and evtest. xinput is a Linux utility that will allow us to configure input device settings for the touchscreen controller, and evtest is an input device event monitor and query tool.

After the Pi finishes rebooting, you should notice that when you move your finger across the touch screen, the pointer should follow correctly in both axes. If you are using the Raspberry Pi 2 Model B, you will need to complete the calibration steps below before the pointer follows your finger correctly (and make sure that you have enabled startx to load automatically – see step 6 in this article).

You can rotate the screen 90 degrees (as we did in this tutorial) and the power connector will be at the bottom of the screen, but you can also rotate it 270 degrees so that the power connector is at the top of the screen. To do this, simply enter fbtft_device.rotate=270 in the /boot/cmdline.txt file. Then change the DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 0 1 line in the /etc/X11/xinit/xinitrc file to DISPLAY=:0 xinput --set-prop "ADS7846 Touchscreen" "Evdev Axis Inversion" 1 0. All you need to do is switch the values of the 0 and 1 at the end of this line.

Now that we have our LCD touchscreen up and running, the final step in the installation is the calibration of touch control. This will make the pointer much more accurate and easier to use.

2. Now we need to install the calibration tool we will be using, xinput_calibrator; and other filters for controlling the touchscreen response. Install the tslib library by entering aptitude install libts-bin:

4. Now we can use ts_calibrate. Enter ts_calibrate at the command prompt (make sure you are still in root mode) to run the ts_calibrate program. The program will consecutively display five crosses on different parts of the screen, which you need to touch with as much precision as possible:

Drag the cross around the screen and observe how closely it follows your finger or stylus to test the accuracy of the calibration. Now press the “Draw” button to enter the drawing mode:

This is kind of a long process, but it is well worth it if you want to get the LCD touchscreen set up properly. So if you have any trouble setting this up or have anything to say, please leave a comment below. Also, if you found this article useful, please share it with your friends!

The RPi LCD can be driven in two ways: Method 1. install driver to your Raspbian OS. Method 2. use the Ready-to-use image file of which LCD driver was pre-installed.

3.Open Terminal of Raspberry Pi (You may need to connect an keyboard and HDMI LCD to Pi for driver installing)git clone https://github.com/waveshare/LCD-show.git

Once this LCD is enabled, meanwhile the default settings for HDMI are changed. If you want to use another HDMI monitor, please run the following command:cd LCD-show/

This LCD can be calibrated using a program called xinput_calibrator which is pre-installed on the CD image. However, it was not pre-installed on original Raspbian OS. So in this case, you should get and install the program manually withsudo apt-get install -y xinput-calibrator

After running these commands, there will be a prompt for four-point calibration shown in the LCD screen. Click the points one by one to finish the touch calibration. Then, the new calibration data will be displayed in the terminal, as shows below. Please get these data for future use.Doing dynamic recalibration:

When using the Raspberry Pi as a server or industrial monitoring device, it is naturally inevitable to be combined with a touch screen. This article will explain in detail how to connect an external capacitive touch monitor with Raspberry Pi, and execute the touch calibration program to obtain more sensitive and precise touch operation.

In order to create a small computer of your own, all you need to have is a raspberry pi board, a display unit and a keyboard (optional). If you are able to find the perfect touch screen, you can create a great DIY computer of your own.

Today, we are going to list down all of the best Raspberry Pi compatible LCD screens available online. These screens are ranked and rated based on the following factors.

Rule of thumb, larger the better. The best of the LCD screens for a Raspberry Pi we got here have a 1080P high resolution and is a full touch screen. There are higher variants available as well but we believe that this is a standard benchmark.

The next important thing that you need to look for in a screen is its compatibility with the various systems that you may be using it other than the Raspberry Pi.

This refers to the ports and other connectivity options through which you can set up the screen to the board. It includes the standard HDMI pots to USB ports and even WiFi compatibility as well. Higher the number of I/O ports, the better

First on our list is an LCD touch screen straight from the official house of Raspberry Pi. It is a 7 inches large touch display that is specifically created for the Raspberry Pi board.

Next on our list is a screen by Kuman, one of the top manufacturer’s in the realm of hobby electronics. This one too is a 7 inches large TFT capacitative touch screen.

Yet another Kuman 7 inches HD Display Screen, this one is quite different from the previous Kuman display screen. That difference is not just in the screen resolution but in a wide range of other things as well.

In this entry, SunFounder comes with a 10.1 inches large HDMI supported IPS LCD display monitor. It has a high resolution of 1280 X 800 pixels and also comes with a camera holder stand.

Next on our list is another SunFounder Raspberry Pi Compatible screen. This one is a simple 7 inches large LCD Display screen with built-in speakers too.

Next product on our list is from a brand called ELECROW. Their LCD screen comes with 5-inches size display and high-resolution picture. It is a resistive touchscreen monitor and comes with a touch pen for easy use.

This LCD touch screen is from SunFounder which has similar dimensions and aesthetical aspect as the previous 10.1 inches Screen by SunFounder and are essentially the same. This is just an older model of the same product.

The last but not least product from our list is a 7-inch LDC touch screen for Raspberry Pi. It supports mini PC like Raspberry 1B+ / 2B / 3B / 3A+/ 3B+/ 4B.

Display resolution or the modes is the number of distinct pixels in each dimension that can be displayed. It is controlled by many of the factors like CRT, flat-panel displays, and LCDs. If the resolution you opt is not compatible then the monitors will stretch and shrink to fit in the specified. It turns result in a great loss of the signal and quality.

In this section, we are going to show you exactly how you can connect your Raspberry Pi to an external display screen. First, let us look at how to connect it using an HDMI port

Using the HDMI port to connect a Raspberry Pi to the LCD screen is one of the simplest and easiest ways to go. Here, all you need to do is to take an HDMI cable and plug it on both sides of the devices. One end goes into the HDMI port of the LCD screen and the other one will go right into the Raspberry Pi’s HDMI port. This set up does not require any special drivers software nor does it require any format of post plugin set up.

Raspberry Pi comes with a tiny 15 pin ribbon cable connector that can support a Display Serial Interface or a DSI standard. This enables fast communication between an LCD screen and the chip.

You can use the Raspberry Pi 7 inch touchscreen display by connecting it with the Raspberry Pi board. All you need to do is to first attach the raspberry pi to the back of the display screen using standoffs and screws that come with the kit.

If not, you can simply connect a power supply to the control board and then connect a small micro USB cable in the control board’s USB port and the micro USB port of the Pi. This should power on the device. You are now done setting up the device and the screen and once the power flows, the device boots up.

If the screen does not automatically turn on when the power source is connected, you may have to connect an existing HDMI display for updating your Raspberry Pi board and then reboot the device.

The Raspberry Pi 7″ Touch Screen Display from the house of Raspberry has a great colour output of 800 x 400 pixels and its capacitive touch is multi-fingered up to 10 fingers. That and the fact that it is specifically built for Raspberry pi Boards by the Raspberry company makes it the best Raspberry Pi LCD screen for your DIY Raspberry pi kit.
