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 ambient light (10,000 lux sunlight) to eliminate glare interference. Maintain a luminance retention rate of ≥ 90% and color shift ΔE ≤ 3 across a wide temperature range (-40℃ ~ 85℃) and vibration environment (10–2000 Hz), preventing driver distraction caused by abnormal display performance.

• ● Enhancing User Experience: Optimize global luminance and chromaticity uniformity (deviation ≤ 5%) and viewing angle performance (visible within ±60° horizontal) to accommodate viewing angles of drivers and passengers. Reduce visual fatigue and strengthen market competitiveness through intelligent day-night mode switching (nighttime luminance ≤ 5 cd/m² with stable color accuracy). 
• ● Empowering Full Industry Chain Efficiency: In production, real-time detection of defects such as Black Mura and glare reduces failure rates. Measurement data enables reverse optimization of evaporation (OLED) and backlight module (LCD) processes to improve mass-production yields. In R&D, provide quantitative support for material selection and structural design of emerging technologies such as Micro-LED, promoting the establishment of industry standards. 
• ● Ensuring Market Access: Use optical measurement results as the core of quality certification to ensure compliance with standards such as ISO 15008 and JEITA ED-3488, enhancing 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 (≤ 50 ms), Black Mura (luminance deviation ≤ 3%), etc. 
• ● Special Environmental Adaptability Tests: Performance degradation under high and low temperatures (e.g., LCD backlight attenuation ≤ 10%, OLED pixel attenuation ≤ 8% at 70℃); luminance recovery speed at -40℃ low temperature (reaches 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 combiner screen, balancing display clarity and driving safety. Key evaluation focuses are as follows: 

• ● Projection Quality: Virtual image distance (typically 2–3 meters to avoid fatigue caused by frequent visual distance adjustment), distortion rate (≤ 1%), and luminance uniformity (deviation ≤ 10%). 
• ● Environmental Adaptability: Virtual image contrast ratio under strong sunlight (≥ 500:1), low-brightness anti-glare performance at night (≤ 30 cd/m²), and visibility under various weather conditions (rain/fog). 
• ● Compatibility: Compatibility with the windshield (ghosting suppression, light transmittance loss ≤ 5%), and driver viewing angle tolerance (clear visibility within ±15° horizontally). 
• ● Safety Compliance: Light intensity that does not interfere with oncoming traffic (≤ 1000 cd/m²), and controlled blue light emission (450 nm band intensity ≤ 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 driving environment via cameras and displays. Its core indicators are as follows:

• ● Imaging Optics: Camera dynamic range (≥ 120 dB, adaptable to backlight and tunnel scenarios); display color reproduction (ΔE ≤ 4 vs. real scenes); frame rate (≥ 30 fps, free of motion blur).
• ● Environmental Tolerance: Anti-glare performance of camera lenses (suppression of nighttime high-beam glare); display luminance at low-temperature startup (-40℃) (≥ 200 cd/m²); resistance to water and fog interference. 
• ● Viewing Performance & Safety: Display field of view (horizontal ≥ 120°); latency (≤ 100 ms), ensuring synchronization with driving operations and eliminating information lag risks.

Optical Performance Evaluation of Automotive Lighting

Covering headlights, taillights, interior ambient lighting, and other components, the evaluation focuses on regulatory compliance and functional performance:

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