RK3568 is widely used in industrial HMI panels, gateways with display, smart terminals, EV charger screens, and embedded control products. For display integration, LVDS and MIPI DSI are two common choices.
LVDS is often preferred for 7-inch, 10.1-inch, and larger industrial TFT panels. It is stable, mature, and suitable for internal display cables.

MIPI DSI is useful for compact Android-style panels and higher-density screens. It requires correct lane count, initialization commands, reset sequence, and timing.

Choose RK3568 when the product needs stronger I/O, industrial positioning, and flexible display options. If the product is a lower-cost smart terminal, RK3566 may also be enough.

Use LVDS when the product uses a 7-inch, 10.1-inch, 12.1-inch, or larger industrial panel and needs stable internal cabling. LVDS is often easier to source for long-life industrial products.
Use MIPI DSI when the product needs a compact, mobile-style panel or high pixel density in a smaller mechanical space. MIPI DSI reduces pin count but increases dependency on panel initialization commands and lane configuration.
For either choice, confirm the board connector. Some RK3568 boards expose LVDS only, some expose MIPI only, and some expose both through different connector options.
RK3568 display Device Tree work usually includes route selection, panel timing, backlight, regulators, reset GPIO, pinctrl, and touch panel nodes. If using Android, additional framework settings may be needed for density, rotation, and touch orientation.
Do not treat the display as only a kernel task. A production HMI must also validate application layout, brightness behavior, boot animation, recovery UI, and OTA screen orientation.
RK3568 is often selected for industrial devices, so validation should include more than normal boot:
Common RK3568 display risks include wrong LVDS mapping, incorrect dual-channel configuration, MIPI panel commands copied from a different panel revision, backlight GPIO polarity mistakes, and touch rotation mismatch.
The best way to reduce risk is to start from a known working vendor reference design and change one variable at a time.
When selecting an RK3568 SBC, compare the board against the final product requirements. Industrial HMI projects often need more than a display connector. They may need isolated RS485, CAN, wide voltage input, watchdog, RTC, Ethernet, Wi-Fi, audio, USB, and secure mounting.
If the display is LVDS, inspect whether the board exposes the correct LVDS channel count and connector pitch. If the display is MIPI, confirm lane count and whether the vendor has tested a similar panel. For either interface, ask for schematic excerpts or a connector definition before ordering custom cables.
RK3568 can run Android or Linux. Android is suitable for app-like touch terminals. Linux is better when the product behaves more like an industrial controller or gateway. The display bring-up may share kernel work, but UI, update, service management, and debugging are different above the kernel.
For Linux HMI, validate Qt, Wayland, X11, browser kiosk, or direct DRM early. For Android HMI, validate launcher, density, rotation, WebView, and OTA screens.
Industrial products often stay in production for years. Keep BSP source, panel datasheets, Device Tree files, and test logs under version control. If the LCD vendor changes panel revision, revalidate timing, LVDS mapping, backlight current, touch firmware, and mechanical fit.
For a new RK3568 HMI project, choose a board and display combination that already has a similar working reference. If the final product needs LVDS, do not start from a board validated only with HDMI. If it needs MIPI DSI, ask for a known-good MIPI panel example. The closer the reference design is to the final hardware, the lower the bring-up risk.
