Introduction

1024x600, 7inch IPS Display for Raspberry Pi, DPI interface, no Touch.

More

Features

  • 7-inch IPS screen, hardware resolution is 1024×600
  • Design based on Raspberry Pi 40pin GPIO interface
  • Drive LCD via DPI interface of Raspberry Pi
  • Supports operating systems like Raspberry Pi OS/Ubuntu
  • Backlight control to lower power consumption
  • Compact size, suit for various projects

【Note】This LCD can only be used for displaying, if you require a touchscreen, please purchase 7inch HDMI LCD(C)(capacitive) or 7inch HDMI LCD(resistive)

Working with Raspberry Pi

Hardware connection

  • 1. Connect the RGB LCD HAT to the JP1 socket on RGB 50P TO 40/50P adapter with an FFC cable (white).
  • 2. Connect the FPC cable (golden) on LCD to the JP2 socket on RGB 50P TO 40/50P adapter.
Note: When connecting, please open the black connector first, and then gently insert the cable. As shown below:

Software settings

If you don't know the difference between the two branches of Raspberry Pi OS, you can check the following introduction #Introducing the Raspberry Pi OS fork

For Raspberry Pi OS Bullseye branch

Please download the latest version of the image from the Raspberry Pi official website.

1. Download the compressed file to the PC, and extract the img file.
2. Connect the TF card to the PC and use SDFormatter to format the TF 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 programming is completed, open the config.txt file in the root directory of the TF card, add the following code at the end of config.txt and save it

dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-DPI-7inch

5. Download the 7inch DPI LCD-KMS display file and put it in the /boot/overlays directory of the TF card, and eject the TF card safely.
6. Turn on the LCD backlight switch.
7. Insert the TF card into the Raspberry Pi, power on the Raspberry Pi, and wait for more than ten seconds to display normally.

For Raspberry Pi OS Buster branch and Ubuntu system

1. Open the config.txt file in the root directory of the TF card, add the following code at the end of config.txt, save and safely eject the TF card.

[pi4]
dpi_timings=1024 1 40 48 128 600 1 13 3 45 0 0 0 60 0 37000000 6

[all]
dtoverlay=dpi24
enable_dpi_lcd=1
display_default_lcd=1
dpi_group=2
dpi_mode=87
dpi_output_format=0x6f005
hdmi_cvt 1024 600 60 6 0 0 0
disable_overscan=1

2. Turn on the LCD backlight switch.
3. Insert the TF card into the Raspberry Pi, power on the Raspberry Pi, and wait for more than ten seconds to display normally.
Note: If the display is abnormal, please try to adjust the VCOM voltage, and be careful not to stay for more than 10 seconds when the display is abnormal. (subject to the actual display effect)

Introducing the Raspberry Pi OS fork

On December 2, 2021, the Raspberry Pi OS for Raspberry Pi split into two branches, the Buster branch and the Bullseye branch.

The Buster branch is a continuation of the old system, which is more stable and uses raspicam as the default camera subsystem.

The Bullseye branch adds some new features, including KMS as the default display driver and libcamera as the default camera subsystem.

Anti-Piracy

Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They're usually some poor copies of our early hardware revisions, and comes with none support service.

To avoid becoming a victim of pirated products, please pay attention to the following features when purchasing:
