== Technical overview ==
* IPS panel with a hardware resolution of 1280×800 pixels
* Ten-point capacitive touch input via a tempered glass touch sensor with a hardness up to 6H
* Optical bonding of the panel to improve image quality
* Connection to the DSI1 port of the Raspberry Pi using a 12 cm DSI cable on newer models or a 15-pin FPC cable on older models
* Power supply through a 4-pin header with an input voltage of 4.75–5.30 V and a minimum current of 0.5 A
* Operating temperature range from 0 °C to 60 °C; storage temperature range from −10 °C to 70 °C
* Supports the Bookworm, Bullseye, and Buster operating systems on the Raspberry Pi
* Graphical brightness adjustment via the system menu or terminal command in the /sys/class/backlight sysfs directory
* Display rotation in Trixie/Bookworm via the “Screen” → “Orientation” menu, while Bullseye/Buster may require manual rotation
* Touch functionality can be disabled by adding the line disable_touchscreen=1 to config.txt

'''Commands and examples – verify before use:'''

git clone https://github.com/waveshare/Waveshare-DSI-LCD
sudo bash ./WS_xinchDSI_MAIN.sh 80C I2C0
sudo reboot
echo X | sudo tee /sys/class/backlight/*/brightness
xset dpms force off
wlr-randr --output DSI-2 --off
wlr-randr --output DSI-2 --on
disable_touchscreen=1
</syntaxhighlight>

== Notes and version constraints ==
* Exact compatibility lists and power values must be verified before purchase or deployment.
* If the motherboard is changed, the driver must be reinstalled because Pi4 and Pi3 require different driver files.
* Synchronous rotation of display and touch is only supported on Trixie/Bookworm; on Bullseye/Buster, touch rotation must be set manually.
* System updates may overwrite previously installed driver files, requiring reinstallation.
* The wlr-randr commands apply only to Labwc and Wayfire interfaces, not to X11.
* Long-term storage in hot, humid environments should be avoided as it can damage the display.
