In general perception, it is widely believed that the requirements for in-vehicle screens are extremely high, and this perception is indeed correct. The specific requirements also depend on different vehicle types and grades. In-vehicle screens can be roughly categorized into the following types: two-wheeled vehicles (electric bicycles, motorcycles), four-wheeled vehicles (passenger cars, trains), and trains (high-speed trains, subways, ordinary speed trains). This article will briefly elaborate on the requirements for screens in mid-to-high-end in-vehicle applications. Our company mainly serves mid-to-high-end customers in the in-vehicle field, so we have some experience to share regarding LCD screens in this field.<\/p>

1\uff09Two-wheeled vehicle LCD screens (electric bicycles, motorcycles, etc.)<\/strong><\/h2>

First, let\u2019s talk about two-wheeled vehicles. The working environment characteristics of such vehicles are as follows:<\/p>

Fully exposed to the outdoors: Subject to sun exposure and rain (high temperatures, heavy rains, humidity fluctuations) and strong ultraviolet radiation;<\/p>

Intense vibration: Severe road bumps during driving (especially on unpaved roads) with large body shaking amplitude;<\/p>

Complex lighting conditions: Direct strong sunlight during the day (prone to reflection) and weak light at night (need to prevent glare);<\/p>

Operation scenarios: Mostly used as instrument panels (displaying speed, battery level, mileage, etc.), may require operation with gloves, or face splashes of dust and mud.<\/p>

Core requirements for the display screen:<\/h3>

Extreme environment resistance:<\/h4>

Wide temperature range: Must support -30\u2103~80\u2103 (to cope with low temperatures in winter and high temperatures after sun exposure in summer), avoiding black screens at low temperatures and brightness attenuation at high temperatures;<\/p>

High protection rating: The entire screen must have at least IP54 (dustproof + splashproof) rating; in some scenarios, IP65 (fully waterproof against water jets, to cope with heavy rains or car washing) is required to prevent rainwater and dust from entering internal circuits.<\/p>

Vibration resistance and durability:<\/h4>

Compliance with vibration resistance standards (e.g., IEC 60068-2-6): The screen module (especially the backlight and touch layer) must have a reinforced design to avoid loose cables, display afterimages, or touch failure caused by long-term vibration;<\/p>

UV resistance and anti-aging: The screen surface must have a UV-resistant coating to prevent the casing from yellowing and the display panel from aging and cracking due to long-term sun exposure.<\/p>

Visibility and operational convenience:<\/h4>

High brightness + anti-glare: Brightness \u2265 600nits; the cover glass surface must undergo AG matte treatment or polarizing technology to reduce reflection;<\/p>

Simple touch\/buttons: If touch is supported, it must be wear-resistant (resistant to scratches from nails and gloves), or physical buttons (more durable) should be used to avoid misoperation.<\/p>

Low power consumption:<\/h4>

Two-wheeled vehicles have limited battery capacity, so the display screen must adopt a low-power design to avoid excessive consumption of battery life.<\/p>

2\uff09Electric four-wheeled vehicles (passenger cars, electric trucks, low-speed electric vehicles, etc.)<\/strong>
<\/h2>

Working environment characteristics:<\/h3>

Semi-enclosed space: <\/h4>

The interior has air conditioning to regulate temperature (but the short-term high temperature inside the car can reach over 60\u2103 after sun exposure in summer, and the low temperature is around -10\u2103 in winter);<\/p>

Moderate vibration: <\/h4>

Vibration during driving is gentler than that of two-wheeled vehicles (depending on the suspension system), but still needs to cope with road bumps;<\/p>

Composite functions: <\/h4>

Displays include instrument panels (vehicle status), central control screens (navigation, entertainment, vehicle control), rear-seat entertainment screens, etc., which need to support complex interactions;<\/p>

Electromagnetic environment: <\/h4>

Dense electronic devices in the car (motors, battery management systems, radars, etc.) are prone to electromagnetic interference.<\/p>

Core requirements for the display screen:<\/p>

Environmental adaptability:<\/h4>

Wide temperature range: Supports -30\u2103~80\u2103 (to cope with temperature differences inside the car in extreme weather), ensuring normal startup at low temperatures and no lag at high temperatures;<\/p>

Anti-fog and anti-condensation: When the humidity inside the car changes (e.g., opening windows on rainy days), the screen surface must be anti-fog treated to avoid condensation affecting display.<\/p>

Display and interaction performance:<\/h3>

High resolution and color: Central control screens must have \u2265 1080P resolution and 100% sRGB color gamut (to ensure accurate colors of navigation maps and videos);<\/p>

Touch experience: Supports multi-touch (e.g., two-finger zooming of maps), operation with gloves (in winter), and anti-misoperation (to avoid accidental touches during driving), with a response speed \u2264 100ms;<\/p>

Anti-glare and brightness adaptation: Screen brightness automatically adjusts with external light (\u2265 500nits in strong light, \u2264 50nits in weak light), paired with anti-glare glass to reduce reflection.<\/p>

Stability and anti-interference:<\/p>

Vibration and impact resistance: Passes automotive-grade vibration tests (e.g., ISO 16750-3) to avoid loose connections between the screen and the car body or display glitches caused by long-term vibration;<\/p>

Electromagnetic compatibility (EMC): Complies with automotive-grade EMC standards (e.g., CISPR 25) to prevent signal abnormalities caused by interference from in-vehicle motors, radars, and other devices.<\/p>

Long lifespan and reliability:<\/p>

Service life \u2265 5 years (matching the vehicle lifecycle), with backlight attenuation rate \u2264 20% (within 5000 hours) to avoid early brightness deficiency.<\/p>

Recommended products:<\/p>

3)Trains (high-speed trains, subways, ordinary speed trains, etc.)<\/strong><\/h2>

<\/p>

Working environment characteristics:<\/h3>

<\/p>

Enclosed space: Indoor temperature (18-26\u2103) and humidity (40%-60%) are stable (regulated by air conditioning systems) with no drastic temperature differences;<\/p>

Gentle vibration: Vibration during driving is mainly smooth (due to high track smoothness) with small impact;<\/p>

Long operation time: Operates 10-16 hours a day, requiring continuous and stable work with short maintenance downtime;<\/p>

Functional scenarios: Include driver\u2019s console displays (showing speed, signals, fault codes), carriage information screens (stations, arrival times), and passenger entertainment screens (videos, news).<\/p>

<\/p>

Core requirements for the display screen:<\/h3>

<\/p>

Long-term operation stability:<\/h4>

<\/p>

Mean Time Between Failures (MTBF) \u2265 50,000 hours (approximately 5.7 years) to avoid frequent black screens or lags (which affect driving safety or passenger experience);<\/p>

Heat dissipation design: Long-term high-load operation (e.g., video playback on entertainment screens) requires low power consumption + efficient heat dissipation to prevent performance degradation due to overheating.<\/p>

<\/p>

Display and adaptability:<\/h4>

<\/p>

High-reliability display: Driver\u2019s console screens need high contrast (\u2265 1000:1) to ensure clear visibility of data under strong light (e.g., at tunnel entrances\/exits); passenger information screens need wide viewing angles to ensure visibility for passengers in different seats;<\/p>

Compatibility: Supports in-vehicle system interfaces (e.g., LVDS, HDMI) and links with train control modules and broadcasting systems to achieve real-time information synchronization (e.g., arrival reminders).<\/p>

Anti-interference and safety:<\/h4>

<\/p>

Strong anti-electromagnetic interference: Train high-voltage power supply systems and communication equipment generate a strong electromagnetic environment, requiring compliance with EN 50155 railway electronic equipment standards to ensure accurate display data (especially for driver\u2019s screens);<\/p>

<\/p>

Maintenance convenience:<\/h4>

<\/p>

Modular design: Facilitates quick replacement of faulty components (e.g., backlight panels, touch modules) to reduce maintenance downtime;<\/p>

Scratch and wear resistance: Surfaces of screens touched by passengers must be hardened to resist daily scratches.<\/p>

<\/p>

Recommended bar displays:<\/h3>
