Introduction

5 inch Resistive Touch Screen LCD, HDMI interface, Designed for Raspberry Pi

Features

  • 800x480 hardware resolution.
  • Resistive touch control.
  • It is compatible and can be directly inserted in any version of Raspberry Pi (For the Raspberry Pi 1 B and Raspberry Pi Zero, HDMI cable is required and should be purchase separately).
  • Provide driver. (support Raspbian\Ubuntu\Kali and Retropie system).
  • When only used for display, does not occupy any I/O resources (using touch function will occupy I/O resources).
  • Support backlight control, more power saving.

New features of the latest version of V2:

  • Improve the backlight drive scheme, lower power consumption. (The power consumption of V1 version is larger)
  • Improve the screw locking method, which is more scientific and reliable. (Compared with the V2 version, the screw of the V1 version is installed in the mezzanine, which has to be reinstalled after falling off and requires more workload.)
  • Improve PCB silkscreen, mark LCD occupied pins. (V1 version is not intuitive enough)
  • Carry out CE, ROHS certification (V1 version has no CE, ROHS certification)

Getting Started

Hardware Connection

  1. Plug the LCD to your Raspberry Pi:
    • There are 40 pins on Raspberry Pi Model A+/B+/2 B/3 B but only 26 pins on the LCD, so you should pay attention to connecting the pins to your Pi accordingly.
  2. Connect the HDMI Connector to both the HDMI interfaces on the LCD and the Pi.
    • You should connect the LCD to Raspberry Pi Model B or Raspberry Pi Zero with an HDMI cable rather than an HDMI Connector.
  3. Turn on the "backlight" switch on the back of the LCD.

Plug the HDMI Connector

Note: This product can only work on a Raspberry Pi but not work on a PC. If the HDMI interface of the LCD is connected to the HDMI interface on a PC, the LCD will not display anything.

Enable touch function

You can enable the touch function in two ways: Method 1. install the driver to your Raspbian/Ubuntu Mate/Kail/Retropie OS. Method 2. use the Ready-to-use image file of which LCD driver was pre-installed. Method 1. Driver installation 1) Download the Raspbian/Ubuntu Mate/Kail/Retropie image from Raspberry Pi website and extract it on a PC. 2) Connect your micro SD card to the PC and write the image to the card using Win32DiskImager. How to write an image to a micro SD card for your Pi? See RPi Image Installation Guides for more details. 3) After the image has finished writing, open the config.txt file in the root directory of the TF card. Add the following code at the end of config.txt, then save and quit the TF card safely:

max_usb_current=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0
hdmi_drive=1

Note: If you use the LCD with Raspberry Pi 4B, you also need to remove or comment out the line dtoverlay=vc4-fkms-V3D from config.txt file. 4) Connect the TF card to the Raspberry Pi, start the Raspberry Pi.The LCD will display after booting up, and then log in to the Raspberry Pi terminal (you can connect the Raspberry Pi to the HDMI display or log in remotely with SSH). 5) Then open the terminal of Raspberry Pi to install the touch driver which can be found in the /boot/ directory. Note: The Raspberry Pi must be connected to the network, or else the touch driver won't be successfully installed. The result is that a small area at the border cannot be touched. If you have installed the touch driver but without a network connection, how to solve the problem? See: #Touch screen calibration part.

git clone https://github.com/waveshare/LCD-show.git
cd LCD-show/
chmod +x LCD5-show
./LCD5-show

The touch function will work after restart. For ease of use, you can set the screen orientation, see: #Screen orientation settings. Method 2. Using Ready-to-use image The image file with the pre-installed driver is located in the IMAGE directory of the CD, or you can download it from #Image. Extract the .7z file and you will get a .img file. Write the image to your micro SD card (How to write an image to a micro SD card for your Pi? See RPi Image Installation Guides for more details). Then insert the card to your Pi, power up and enjoy it.

Screen orientation settings

After touch driver installed, the screen orientation can be set by these commands:

  • 0 degree rotation
cd LCD-show/
./LCD5-show 0
  • 90 degree rotation
cd LCD-show/
./LCD5-show 90
  • 180 degree rotation
cd LCD-show/
./LCD5-show 180
  • 270 degree rotation
cd LCD-show/
./LCD5-show 270
If you are using Raspbian-lite, the commands should be
  • 0 degree rotation
cd LCD-show/
./LCD5-show lite 0
  • 90 degree rotation
cd LCD-show/
./LCD5-show lite 90
  • 180 degree rotation
cd LCD-show/
./LCD5-show lite 80
  • 270 degree rotation
cd LCD-show/
./LCD5-show lite 270

Touch screen calibration

This LCD can be calibrated through the xinput-calibrator program. Note: The Raspberry Pi must be connected to the network, or else the program won't be successfully installed.

  • Run the following command to install:
sudo apt-get install xinput-calibrator  
  • Click the "Menu" button on the taskbar, choose "Preference" -> "Calibrate Touchscreen".
  • Finish the touch calibration following the prompts. Maybe rebooting is required to make calibration active.
  • You can create a 99-calibration.conf file to save the touch parameters (not necessary if file exists).
sudo mkdir /etc/X11/xorg.conf.d
sudo nano /etc/X11/xorg.conf.d/99-calibration.conf
  • Save the touch parameters (may differ depending on LCD) to 99-calibration.conf, as shown in the picture:

FAQ

Question:
What is the difference between the V1 version and the V2 version of the 5inch HDMI LCD?
Answer:
The V2 version mainly made the following modifications on the basis of the V1 version:
  • Improve the backlight drive scheme, lower power consumption. (The power consumption of V1 version is larger)
  • Improve the screw locking method, which is more scientific and reliable. (Compared with the V2 version, the screw of the V1 version is installed in the mezzanine, which has to be reinstalled after falling off and requires more workload.)
  • Improve PCB silkscreen, mark LCD occupied pins. (V1 version is not intuitive enough)
  • Carry out CE, ROHS certification (V1 version has no CE, ROHS certification)


Question:
I can’t make the LCD work normally with the Raspberry Pi image. What is the reason?
Answer:
The LCD must be installed with the driver before it can be used normally. For details, please refer to the relevant introduction in the user manual.see#Getting started



Question:
Why does the touchscreen not work well?
Answer:

Now, we only provide touch screen drivers for Raspbian and Ubuntu Mate. How to install the driver? See:#Method_1._Driver_installation


Question:
Why does the image provided on the wiki does not work on my Pi?
Answer:
  • The image provided may differ depending on batches, however, some Images are just available for Pi 2 (or before, but not for Pi 3). In such cases, you can download the latest version from Raspberry Pi website and install the driver. See:#Method_1._Driver_installation
  • Make sure the hardware connection is correct and connects fine.
  • Make sure you've written the image to your SD card using the software File:Win32DiskImager.zip rather than just copy and paste.
  • When the Raspberry Pi starts normally, the PWR light is always on and the ACT light is blinking. If you find that both lights are always on, it may be that the TF card failed to burn the image or the TF card is in poor contact with the Raspberry Pi.
  • It is strongly recommended to use a stand-alone 5V/3A power adapter because the USB port of PC might not have enough power to support the Pi and LCD.


Question:
Could I only connect the HDMI cable?
Answer:
No, the HDMI interface is only used for display. You also need to insert the GPIO for touching and power. BTW, you can also connect the external power adapter to the USB interface for power if LCD has an external power interface.


Question:
What is the working temperature of this LCD?
Answer:
The working temperature is 0°C -- 70°C


Question:
What is the working current for the 5inch HDMI LCD when it works normally?
Answer:
When working with 5V input, the current is about 235mA with backlight on and 45mA with backlight off.


Question:
Can 5inch HDMI LCD be connected to a computer as a display screen?
Answer:
It can only support Raspberry Pi, not suitable for connecting to a computer as a monitor.
