Definition
A single board computer (SBC) is a complete computer on a single circuit board — processor, memory, storage, I/O, and video output. SBCs like the Raspberry Pi, NVIDIA Jetson, and industrial i.MX boards are increasingly used as host processors in embedded display systems, replacing traditional PC-based or proprietary processor platforms.
Common SBCs in Display Applications
| SBC Platform | Video Output | Best Fit |
|---|---|---|
| Raspberry Pi 4/5 | HDMI (2x), MIPI DSI | Digital signage, retail kiosks, prototyping |
| NVIDIA Jetson Nano/Orin | HDMI, DisplayPort, MIPI | AI-enabled displays, machine vision HMI |
| BeagleBone | HDMI, LCD parallel | Industrial control, low-power embedded |
| Rockchip RK3588 | HDMI 2.1, DP, MIPI DSI (2x) | High-performance multi-display systems |
| NXP i.MX 8/93 | MIPI DSI, LVDS, HDMI | Medical devices, automotive HMI, industrial |
Display Integration Challenges with SBCs
- Video output matching: SBC outputs rarely match display panel inputs directly
- Resolution and timing: SBC video drivers must be configured for panel-specific timing
- Backlight control: SBC GPIO must be mapped to backlight enable and PWM dimming
- Touch integration: USB or I2C touch controllers need OS driver support
- Thermal management: SBCs in enclosed assemblies need thermal design attention
How Display Logic Supports SBC-Based Systems
Display Logic supplies LCD controller boards and interface adapters bridging SBC video outputs to LCD panel inputs. Display Logic also provides complete turnkey display assemblies pre-configured for specific SBC platforms, including Raspberry Pi display kits with pre-loaded timing configurations.
Frequently Asked Questions
What display interfaces does Raspberry Pi support?
Raspberry Pi 4 and 5 support HDMI (full-size and micro), MIPI DSI (via the display connector), and USB. Most industrial LCD panels require LVDS or TTL, necessitating a Display Logic controller board for integration.
Can I use an NVIDIA Jetson with an industrial LCD?
Yes. The Jetson supports MIPI DSI, HDMI, and DisplayPort. Display Logic provides interface adapters and controller boards for connecting Jetson platforms to industrial TFT LCD panels for machine vision and AI-enabled HMI applications.
