50H-800480-IPS
Introduction
Overview
50H-800480 series display, produced by the Waveshare team, is designed for users who need a lightweight DSI display. Compared with the traditional DSI screen, it is lighter and more convenient for secondary development.
Features
- 5-inch IPS screen, 800 x 480 hardware resolution.
- 5-point capacitive touch control, toughened glass panel, hardness up to 6H (this function is only for the touch version).
- Support Pi4B/3B+/3A+/3B/2B/B+/A+, and some CM3/3+/4 expansion board need a DSI Cable 15cm.
- Directly drive the LCD via the DSI port of the Raspberry Pi, and the refreshing rate is up to 60Hz.
- When working with the Raspberry Pi, it supports Raspberry Pi OS/Ubuntu/Kali and Retropie, and is driver-free.
- Support adjusting the backlight via the software and saving more power.

Working With Raspberry Pi
Hardware Connection
With FFC cable, you can connect 50H-800480 to the DSI port of the Raspberry Pi, as shown below:
Software Setting
For Raspberry Pi OS/Ubuntu/Kali/Retropie systems:
- 1. Please download the newest image from the official Raspberry Pi website. Download the compressed file to the PC and unzip it to get the ".img" file.
- 2. Connect the TF card to the PC and use the SDFormatter to format the TF card.
- 3. Open Win32DiskImager software, choose the system image prepared in the first step, and click write to write the system image.
- 4. After writing, open the config.txt file on the root directory of the TF card. Add the following codes at the end of config.txt, save it and then safely remove the TF card.
dtoverlay=vc4-kms-v3d dtoverlay=vc4-kms-dsi-7inch
- 5. Insert the TF card into the Raspberry Pi, power on it, and then enter the display after waiting for a few seconds. It can be normally touched after booting the system.
Backlight Control
Input the following commands on the terminal to adjust the brightness.
echo X > /sys/class/backlight/rpi_backlight/brightness
X means any number in 0~255, 0 means the darkest, and 255 means the brightest.
echo 100 > /sys/class/backlight/rpi_backlight/brightness echo 0 > /sys/class/backlight/rpi_backlight/brightness echo 255 > /sys/class/backlight/rpi_backlight/brightness
In addition, Waveshare provides the corresponding demo (the demo is only for Raspberry Pi OS), and users can download to install in the following ways:
wget https://files.waveshare.com/upload/f/f4/Brightness.zip unzip Brightness.zip cd Brightness sudo chmod +x install.sh ./install.sh
After installing, you can open the demo in Menu -> Accessories -> Brightness, as shown below:
Screen Sleep Mode
The display enters sleep mode after inputting the following commands:
xset dpms force off
Disable Touch
Add the following commands to disable the touch at the end of the "config.txt" file. (config file is in the TF card root directory, which can also be accessed by the command: sudo nano /boot/config.txt.)
disable_touchscreen=1
Note: After adding the commands, you need to reboot it to take effect.

FAQ
Check the system version using "uname --all". If it's kernel version 6.6.20, run "sudo rpi-update pulls/6050" to fix it.
Note: Take care to back up any important data in your image before updating in case there is a regression.

The hardware connection between DSI LCD and Pi5:
(1) A DSI cable (official Raspberry Pi cable or Waveshare Pi5-Display-Cable-200mm) for Pi 5 is required. Please ensure the proper orientation with the SODIMM.
(2) Priority usage for Pi5's DSI1 interface.
If use the DSI0 interface, you need to add "dtoverlay=vc4-kms-dsi-7inch,dsi0" in the config.txt file
2. Check the DSI LCD version.
(1) The latest DSI LCD version compatible with Pi5 is Rev2.2, which can be directly used.
(2) If you purchased the product earlier, such as the Rev2.1 version (or older), due to the power detection mechanism of Pi5, it may misidentify the capacitors on the DSI LCD as a false short-circuit state, preventing the system from booting. In this situation, you can manually remove the large capacitors at the four positions marked in red circles in the image below.
3.Software Setup:
For the Pi5, use the Bookworm system. (Please note, Pi5 currently only supports Bookworm, not Bullseye or Buster).
(1) Go to the Raspberry Pi official website: https://www.raspberrypi.com/software/operating-systems/. Download the latest version of the Bookworm image. Download the compressed file to your PC and extract it to obtain the .img file.
(2) Connect the microSD card (TF card) to your PC and use the SDFormatter software to format the microSD card.
(3) Open the Win32DiskImager software. Select the system image prepared in Step 1 and click 'Write' to burn the system image.
(4) After the writing process is complete, open the 'config.txt' file in the root directory of the microSD card. Add the following code at the end of 'config.txt', save it, and safely eject the microSD card.
dtoverlay=vc4-kms-v3d dtoverlay=vc4-kms-dsi-7inch
(5) Insert the TF card into the Raspberry Pi, power it, and then enter after waiting for a few seconds. Then, the system boots and can be touched mormally.
Note that if use the DSI0 interface at the same time, you need to add the additional commands: "dtoverlay=vc4-kms-dsi-7inch,dsi0"
