Technical overview

• Panel: 4.3-inch IPS/QLED, native resolution 800 × 480 pixels
• Viewing angle: 160°
• Color gamut: 50 % NTSC (IPS) or 78 % NTSC (QLED)
• Brightness: 300 cd/m²; contrast ratio 1200:1; color depth 16.7 M colors
• Refresh rate up to 60 Hz
• Driven via the Raspberry Pi DSI port; no additional drivers required for the listed operating systems
• Housing dimensions: 105.42 × 67.07 × 2.90 mm (display); touch variants approx. 112.40 × 75.10 × 5.00 mm or 106.10 × 67.80 × 5.20 mm
• Connection via FFC cable to the DSI port; gold finger on the display side faces upward

• Software backlight adjustment saves power compared with hardware control

Commands and examples – verify before use: 

dtoverlay=vc4-kms-v3d
dtoverlay=vc4-kms-dsi-7inch
dtoverlay=vc4-kms-dsi-7inch,dsi0
echo X | sudo tee /sys/class/backlight/*/brightness
video=DSI-1:800x480M@60,rotate=90
display_rotate=1 #1: 90; 2: 180; 3: 270
ENV{ID_INPUT_TOUCHSCREEN}=="1", ENV{LIBINPUT_CALIBRATION_MATRIX}="0 -1 1 1 0 0"
Option "CalibrationMatrix" "0 1 0 -1 0 1 0 0 1"

Notes and version constraints

• The compatibility list covers only the Raspberry Pi models named in the source; other boards are unconfirmed
• When using the DSI0 interface (Pi5/CM4 only), append “dsi0” to the dtoverlay entry
• Older revisions (e.g., Rev2.1) may cause power-detection issues on Pi5; removing certain capacitors may be required
• The GUI steps described apply mainly to Trixie/Bookworm; older systems such as Bullseye/Buster need manual touch rotation settings
• Installing the Waveshare Brightness tool requires internet access for the download
• The commands and file paths provided should be verified against the specific system before use
