What this page is
This page is for OEM teams sourcing a commercial-vehicle display and HUD manufacturer in China. It covers the instrument clusters, head-up displays and CAN bus displays we make and how they are built and validated. Every unit is quoted against your specification rather than shipped as a fixed catalogue part — send drawings and we typically reply within one business day.
The detail below is the qualification pack we share with engineering teams at the start of a commercial-vehicle cockpit or instrumentation programme. For the engineering background — what each display type does and how to write the specification — see the displays and HUD technical guide.
Who Youlai is
Changsha Youlai Electronic Technology Co., Ltd. is an IATF 16949 certified OEM electronics manufacturer based in Changsha, Hunan, China. We supply vehicle electronics — instrument clusters, displays, body control, power distribution, switching and sensors — to commercial-vehicle and construction-machinery OEMs including SANY, XCMG, ZOOMLION, SINOTRUK, YUTONG and BYD. The full named list is on the About page.
The quality system is certified to IATF 16949. Environmental and OH&S system certificates (ISO 14001 / ISO 45001) are shared as current PDFs during qualification — see the OEM sourcing guide for what to verify.
What we make in Displays & HUD
The PBX family covers the driver-facing instrumentation of a commercial vehicle, from the cluster behind the wheel to the head-up display on the windscreen. Every model below is a published platform we build to your OEM specification.
| Model | Type | Supply | Image | Vehicle data |
|---|---|---|---|---|
| PBX‑961 | Windscreen HUD (W-HUD), dual free-form mirror | 18–32 VDC | 15-inch virtual image at 2.4 m | Over the vehicle bus |
| PBX‑2203 | Combiner HUD (C-HUD) | 9–32 VDC | 8–12 inch image at 1.5–2 m | Agreed at quotation |
| PBX‑2301 | 8-inch combined cluster, plateau / new-energy | 9–32 VDC, 24 V rated | 8-inch IPS, ≥ 1080 × 720 | 2 × CAN with CAN-FD; 2 AV camera inputs |
| PBX‑2202 | 4.6-inch smart cluster | 9–32 VDC | 960 × 320 IPS | Bluetooth phone link and wireless CarPlay; vehicle bus agreed at quotation |
How the HUD optics and data path work is in the commercial vehicle HUD guide; choosing between cluster types is in the instrument cluster guide. PBX-2402 is the compaction-roller cluster for construction machinery. CMS electronic mirrors and surround-view are system-level solutions, configured by camera count, mounting geometry and project specification rather than sold as a single fixed part.
The full Displays & HUD catalogue, including the model matrix, is on the Displays and HUD overview page; buyers consolidating a whole program can also source body control, power distribution, switches and sensors from the same supplier across the four product families.
Lines and test equipment
The Changsha factory runs three SMT lines (solder-paste print, SPI, JUKI placement, multi-zone reflow and AOI), one THT auto-flow line with wave soldering, and four assembly lines. Every assembly line ends in a functional test station. In-circuit testing is done on the ICT station. Annual capacity across the factory is 1.5 million sets.
These rigs belong to the Changsha lab, which validates models across the four product families.
| In-house rig | What it tests |
|---|---|
| Water-spray chamber | IPX water ingress |
| Dust chamber | IP5X / IP6X dust ingress |
| Salt-spray chamber | Accelerated corrosion |
| Temperature and humidity chamber | Programmable temperature and humidity profiling |
| Climate cycling chamber | Long-form humidity and temperature cycling |
| Thermal-shock chamber | Hot–cold step change |
| Aging chamber | Sustained burn-in at elevated temperature |
| Vibration and shock | Multi-axis vibration table; drop and bump |
| ESD generator | ESD immunity per IEC 61000-4-2 |
| ISO 7637 simulator | Supply-line transient immunity |
| Surge generator | Lightning surge immunity |
| Hipot tester | Dielectric withstand and insulation resistance |
| HIL simulation rig | Hardware-in-the-loop vehicle-network simulation |
In-house EMC work is pre-compliance. Formal EMC certification, when a programme requires it, is at accredited third-party laboratories. The quality page has photos of the lines and of the rigs it shows. Dust ingress, vibration and mechanical shock are described on the environmental and EMC page.
How a programme starts
- Briefing. These help if you already have them: target vehicle / platform, expected annual volume, working voltage (12 V / 24 V), display size and resolution, the data the screen has to show, communication protocol (CAN 2.0 / CAN-FD / J1939, LVDS for camera feeds), brightness and sunlight-readability targets, IP rating, temperature range, mounting and connector preference.
- Selection or custom. We propose the closest standard PBX model. If your program needs a different screen size, optical geometry, bracket, software theme or bus matrix, we quote a custom variant on the same PBX platform rather than starting from zero. Where the requirement does not map onto any existing platform, we scope it as a new design instead of forcing a fit.
- Software and graphics ownership. We agree early on who owns the UI theme, the warning-lamp set and the bus matrix — a configurable software build or a fully custom graphics package. This decision drives lead time more than any hardware line item.
- Sample & validation. Engineering samples for standard variants, with validation supported by our in-house environmental lab and EMC pre-compliance — temperature cycling, vibration, sunlight loading and bus conformance.
- Mass production. On the lines above, with in-process inspection, an end-of-line display test and traceable batch records. The drawing package, BOM and quality-system documentation are released at the milestones agreed with you. Market compliance paths (UNECE / e-Mark where applicable, UN-R46 / R151 for camera-monitor systems, SASO/SABER, FCC authorisation, DOT/FMVSS where applicable) available upon project requirement.
Why programmes pick this supplier
- Engineering-led, not catalogue-only. Every PBX model is a project we own end-to-end, from PCB and optical design through bus integration. Custom variants are routine, not an exception.
- Full product-family coverage. Buyers consolidating the electronics side of a program get displays, body control, power distribution, switches and sensors from one supplier — see the four product families.
- Cabin and exposed-mount sealing. Where a camera or monitor mounts outside the cab, the design rationale behind IP65 / IP67 enclosures is documented, not assumed.
