This section collects TFT LCD display configuration references for embedded SBC development. The goal is to help engineers quickly find panel information, interface notes, Device Tree examples, and related display bring-up guides for Rockchip-based Android and Linux platforms.
These configuration notes are mainly focused on practical display integration work, including LVDS, MIPI DSI, RGB, backlight control, panel timing, touch panel setup, and board-level display debugging.

TFT LCD modules used in embedded SBC projects may use different display interfaces depending on resolution, system architecture, cable length, and product requirements.
LVDS is widely used in industrial display systems. It provides stable signal transmission for medium and large TFT LCD panels and is commonly used with 7-inch, 10.1-inch, 12.1-inch, and 15.6-inch display modules.
LVDS is often suitable for industrial HMI panels, control terminals, medical equipment, EV charger displays, and machine interface products.
MIPI DSI is common in compact embedded systems, Android panels, smart home control panels, and mobile-style display products. It supports high-speed serial display transmission with fewer signal lines than RGB.
MIPI DSI integration usually requires correct panel initialization commands, lane configuration, timing parameters, reset sequence, and backlight control.
RGB display interfaces are common in lower-resolution embedded panels. RGB is straightforward and widely supported by many ARM SoCs, but it requires more signal lines than LVDS or MIPI DSI.
RGB panels are often used in cost-sensitive HMI products, small industrial displays, and simple control terminals.
eDP is often used for higher-resolution panels, especially notebook-style display modules such as 13.3-inch, 15.6-inch, or larger Full HD panels. It is suitable for products that need higher resolution and cleaner internal cabling.
When integrating a TFT LCD with an embedded SBC, engineers should verify both hardware and software configuration.
The display configuration examples are also maintained in the GitHub repository:
This repository includes example Device Tree configuration files, display notes, and panel integration references for Rockchip-based embedded SBC projects.
The files in this section are intended as practical references. Actual display configuration may vary depending on the SBC model, SoC version, kernel version, Android or Linux BSP, panel revision, touch controller, and board-level wiring.
Before using a configuration in production, always compare it with:
A working display configuration depends on both hardware design and software setup. Device Tree files should be treated as board-specific engineering references, not universal drop-in configurations.
