Technical Specifications of Our Speedometer Displays

​

1. Accuracy: The Cornerstone of Reliability​

Accuracy is the bedrock of speedometer displays, directly influencing driving safety and compliance with traffic regulations. Our speedometer displays leverage state-of-the-art high-precision sensors and advanced signal processing algorithms. The measurement error of our standard products is meticulously controlled within ±0.8% of the actual speed, surpassing many industry benchmarks. For high-performance vehicles that demand pinpoint speed control during high-speed maneuvers or commercial vehicles adhering to strict speed limits, our displays offer rock-solid reliability. In specific custom models designed for racing cars, we can further optimize the accuracy to within ±0.5%, ensuring drivers have exact speed data at their fingertips.

​

2. Display Resolution and Visual Experience​

We offer speedometer displays with a wide spectrum of resolutions to meet varying visual demands. For basic vehicle models where simple speed indication suffices, our entry-level displays come with a resolution of 240×128 pixels, presenting clear and legible speed values. In contrast, for high-end luxury cars and advanced commercial vehicles that require detailed information display, our high-resolution displays can reach up to 1920×720 pixels. This high resolution enables not only sharp speed digits but also the integration of rich additional information, such as navigation prompts, vehicle health status, and real-time traffic data.​

The display characters are designed with user-friendliness in mind. They feature large, bold fonts that remain easily readable even under intense sunlight or in dimly lit environments. Many of our models are equipped with anti-glare technology, reducing reflections on the display surface. Additionally, advanced backlighting systems are employed, with adjustable brightness levels ranging from 50 nits for nighttime driving to 1000 nits for outdoor use under direct sunlight, ensuring optimal visibility in all lighting conditions.

​

3. Compatibility: Seamless Integration​

Our speedometer displays are engineered for high compatibility with diverse vehicle types and electronic control units (ECUs). We support multiple industry-standard communication protocols, including CAN (Controller Area Network), LIN (Local Interconnect Network), and FlexRay. This wide protocol support allows for seamless integration with existing vehicle systems, whether it's a gasoline-powered sedan, a diesel-powered truck, an electric vehicle, or a hybrid model.​

Moreover, we provide a range of interface options, such as HDMI, USB, and LVDS, facilitating easy connection to other in-vehicle devices like infotainment systems and ADAS (Advanced Driver Assistance Systems). Our technical team also offers comprehensive integration support, helping customers ensure that the speedometer display functions harmoniously with the entire vehicle electronics ecosystem.

​

4. Operating Temperature Range: Adaptability to Harsh Environments​

To guarantee reliable operation across various climates, our speedometer displays are built to endure a broad operating temperature range. The standard models can function stably within -40℃ to 85℃, covering most common environmental conditions worldwide. For special applications in extreme environments, such as vehicles operating in the frigid Arctic regions or the sweltering deserts, we can customize displays with an extended temperature range of -55℃ to 105℃.​

These extreme-temperature-resistant models are designed with specialized materials and components. For example, the liquid crystal panels in low-temperature models are formulated to maintain fluidity and functionality even in sub-zero conditions, while high-temperature models feature enhanced heat dissipation structures and temperature-resistant circuit boards to prevent overheating and ensure accurate speed display.

​

5. Additional Functions: Enhancing Driving Intelligence​

Beyond the basic speed display, our speedometer displays are packed with a plethora of additional functions. Integrated odometer and trip meter functions accurately record vehicle mileage, which is crucial for maintenance scheduling and fleet management. Fuel level indicators, engine RPM displays, and gear position indicators provide drivers with comprehensive vehicle operation status information.​

Our advanced models also incorporate intelligent warning systems. These systems can detect and alert drivers to potential issues, such as low tire pressure, engine malfunctions, and impending maintenance needs. Some models even support connectivity with smartphones via Bluetooth or Wi-Fi, enabling drivers to receive navigation directions, incoming call notifications, and music control directly on the speedometer display, enhancing both driving convenience and safety.

​

6. Durability and Reliability: Built to Last​

We place great emphasis on the durability and reliability of our speedometer displays. The enclosures are constructed from high-strength, impact-resistant materials, capable of withstanding vibrations, shocks, and minor collisions during vehicle operation. Rigorous durability testing is conducted, including drop tests, vibration tests, and long-term continuous operation tests.

 

Electronically, the components are selected for their high quality and long lifespan. The displays undergo strict electrical performance testing, ensuring stable operation over extended periods. With an average lifespan of over 100,000 hours for normal usage conditions, our speedometer displays offer long-term peace of mind for vehicle manufacturers and end-users alike.
