What is a car front mounted LCD screen?
Car mounted front mounted LCD screen refers to the LCD display screen directly integrated into the overall vehicle design during the original manufacturing process of the car. It is developed synchronously with the vehicle, rigorously certified, and installed as a native component of the car in positions such as the dashboard, center console, passenger entertainment screen, rear entertainment screen, and even electronic rearview mirror.
Simply put, it is the inseparable screen that comes with the car when it was born, integrated with the vehicle.
Core features (compared to the front and rear)
Feature dimension | Front mounted LCD screen | Rear mounted LCD screen/consumer grade screen |
1. Integration level | highest. Deeply integrated with the vehicle's electronic and electrical architecture, it is a part of the vehicle. | Independent cheating. By modifying and connecting, it is an additional device. |
2. Design and Verification | Develop synchronously with the vehicle model. The appearance, structure, and electrical interfaces are fully customized and require years of vehicle grade verification. | Universal design. Adapt to multiple vehicle models, with verification standards far lower than vehicle specifications. |
3. Quality standards | Vehicle grade (AEC-Q series, etc.). Extreme temperature (-40 ℃~85 ℃ or above), anti vibration, anti impact, ultra long life (≥ 8-10 years), high reliability. | Consumer grade or industrial grade. The requirements for environmental adaptability and lifespan are much lower. |
4. Safety and Compliance | Compliant with automotive safety standards (such as ISO 26262 functional safety). When it comes to driving safety (such as instruments), it is necessary to ensure zero delay, pocket screen, and high brightness readability. | No mandatory safety requirements. Malfunctions usually do not directly endanger driving safety. |
5. Supply Chain and Supply | Directly supplied to the host factory (Tier 1). The order cycle is long, and stable production capacity is required, requiring participation in the entire vehicle project. | Supply to modification shops or end consumers, flexible but decentralized. |
Why are the requirements so strict? ——Key technical barriers for front mounted screens
1. Environmental Extremity: Must withstand high temperatures of nearly 100 ℃ inside the dashboard under summer sun exposure, as well as extreme cold below -30 ℃ in winter, and be able to work normally immediately.
2. Ultra long lifespan and stability: The design lifespan of automobiles usually exceeds 15 years, and the screen needs to ensure that there are basically no faults during the entire vehicle lifecycle (the defect rate requirement is PPB level, one in a billion).
3. Special requirements for optical performance:
High brightness&anti glare: It must be clearly readable under noon sunlight (>10000 lux) and not glaring at night, usually requiring a brightness of over 1000 nits and special surface treatment.
Wide temperature operation: The response speed of the LCD must be stable throughout the entire temperature range to avoid low-temperature ghosting or high-temperature failure.
4. Mechanical reliability: It must withstand continuous vibration and bumps of the vehicle, as well as not easily shatter and cause secondary injury in collisions.
5. Electromagnetic compatibility: Cannot interfere with other electronic devices in the car (such as radio, CAN bus), and cannot be interfered with by itself.
Main application locations
LCD instrument panel: replacing traditional pointers, displaying vehicle speed, RPM, navigation, ADAS information, etc., with the highest safety level.
Central control information entertainment screen: the core interactive interface for controlling air conditioning, media, vehicle settings, mobile phone interconnection, etc.
Passenger entertainment screen&rear entertainment screen: Provides audio and video entertainment functions.
Electronic rearview mirror (streaming rearview mirror): displays the rear view through the camera without blind spots.
Air conditioning control screen/rear control screen: integrated touch control panel.
HUD head up display: The imaging source that projects information onto the windshield is essentially a miniature high brightness display screen.
industry trends
Large screen and multi screen: From a single central control screen to a continuous connected screen and multiple independent screens, creating an "intelligent cockpit" experience.
High definition: The resolution has rapidly moved from the early 800 * 480 to 2K or even 4K.
New technology integration: Mini LED backlight (achieving higher contrast and HDR), OLED (flexible, ultra-high contrast, used for high-end models), local dimming, high-performance touch (haptic feedback) and other technologies are accelerating the entry of vehicles.
Integration and Intelligence: The screen and cockpit domain controller are deeply integrated, software defined display content is achieved, and multi screen interaction and scene linkage are realized.
In summary, the in car front mounted LCD screen is far from a simple "screen". It is a "core cockpit component" that deeply integrates optoelectronic technology, material science, automotive electronics, and functional safety, representing the face and interaction center of automotive intelligence and digitization. Its technological barriers and added value are far higher than consumer displays.
