Optical Performance Evaluation of Automotive Displays

I. Core Value Positioning

• ● Ensuring Driving Safety: Control high luminance (≥1000 cd/m²) and low reflectivity (≤2%) under strong light (10,000 lux sunlight) to avoid glare interference. In a wide temperature range of -40℃~85℃ and a vibration environment of 10-2000Hz, ensure a luminance retention rate of ≥90% and a color shift ΔE ≤3 to prevent driving distraction caused by display abnormalities.

• ● Enhancing User Experience: Optimize global luminance/chromaticity uniformity (deviation ≤5%) and viewing angle characteristics (visible within ±60° horizontally) to adapt to different viewing angles of drivers and passengers. Reduce visual fatigue and enhance product market competitiveness through intelligent switching of day-night modes (nighttime luminance ≤5 cd/m² with stable color accuracy).
• ● Empowering Full Industry Chain Efficiency: On the production side, real-time detection of defects such as BlackMura and glare reduces the defective rate. Reverse-optimize evaporation (OLED) and backlight module (LCD) processes based on measurement data to improve mass production qualification rates. On the R&D side, provide quantitative basis for material selection and structural design of new technologies such as Micro-LED to promote the establishment of industry standards.
• ● Ensuring Market Access: Take optical measurement results as the core of quality certification to ensure products comply with standards such as ISO 15008 and JEITA ED-3488, and enhance consumer trust.

II. Key Testing Items

• ● Routine Optical Parameters: Luminance, contrast ratio (static ≥1000:1, OLED dynamic up to 10⁶:1), color gamut (e.g., DCI-P3 coverage ≥90%), viewing angle, reflectivity, glare level, response time (≤50ms), BlackMura (luminance deviation ≤3%), etc.
• ● Special Environmental Adaptability Tests: Performance attenuation tests under high and low temperatures (e.g., LCD backlight attenuation rate ≤10% and OLED pixel attenuation rate ≤8% at 70℃ high temperature); luminance recovery speed after startup at -40℃ low temperature (reaching 80% of rated value within ≤3 seconds).

Optical Testing System for Automotive HUD (Head-Up Display)

Optical Performance Evaluation of Automotive HUD (Head-Up Display)

HUD projects information onto the windshield or dedicated screen, balancing clarity and driving safety. The key evaluation focuses are as follows:

• ● Projection Quality: Virtual image distance (typically 2–3 meters to avoid visual distance switching fatigue), distortion rate (≤1%), and luminance uniformity (deviation ≤10%).
• ● Environmental Adaptability: Virtual image contrast ratio under strong light (≥500:1), low-luminance anti-glare at night (≤30 cd/m²), and penetrability in different weather conditions (rain/fog).
• ● Compatibility: Matching performance with the windshield (avoiding ghosting, light transmittance loss ≤5%), and driver’s viewing angle tolerance (clearly visible within ±15° horizontally).
• ● Safety Compliance: Light intensity that does not interfere with oncoming vehicles (≤1000 cd/m²), and no excessive blue light (intensity of the 450nm band ≤20%).

Optical Testing System for Automotive CMS (Camera Monitoring System)

Optical Performance Evaluation of Automotive CMS (Camera Monitoring System)

As a replacement for traditional rearview mirrors, CMS reconstructs the external environment through cameras and displays. Its core indicators are as follows:

• ● Imaging Optics: Camera dynamic range (≥120dB, adaptable to backlight/tunnel scenarios); display color reproduction (deviation from real scenes ΔE ≤4); frame rate (≥30fps, no motion blur).
• ● Environmental Tolerance: Anti-glare performance of camera lenses (suppression of nighttime high-beam glare); display startup luminance at low temperature (-40℃) (≥200 cd/m²); resistance to water/fog interference.
• ● Viewing Distance and Safety: Display viewing angle (horizontal ≥120°); latency (≤100ms), ensuring synchronization with driving operations and no risk of information lag.

Optical Performance Evaluation of Automotive Lighting

Covering headlights, taillights, interior ambient lights, etc., the evaluation focuses on regulations and functionality:

• ● Headlights: High beam irradiation distance (≥150 meters); clarity of low beam cut-off line (to avoid glare for oncoming vehicles); color temperature (3000K-6000K, balancing penetration and recognition); penetration rate in rainy/foggy weather.
• ● Signal Lights (Taillights/Turn Signals): Luminous intensity (compliant with ECE R70 standard); flicker frequency (1-2Hz); angular visibility (±45° horizontally, ±15° vertically).
• ● Interior Lighting: Adjustable luminance range (0.1-10 cd/m²); warmth of color temperature (to avoid blue light stimulation); uniformity (no direct glare) to enhance ride comfort.
