GS-291 Display Ambient Reflectance Color Tester
The Display Ambient Reflectance Color Tester is a modular, high-precision system that measures ambient light reflectance across numerous display types and form factors. As display sizes increase and geometries become more complex, sampling integrating spheres with custom integrated measurement ports have become the benchmark for flexible, accurate, and repeatable evaluation.
The GS-291 sets a new standard with a precision-engineered port that enables reliable reflectance testing on virtually any display size, eliminating the physical constraints of traditional sphere-based setups. Paired with interchangeable front faceplates that accommodate flat, curved, convex, and concave surfaces, the system delivers true modularity and adaptability, purpose-built for the demands of next-generation display technologies.
Key Application Areas:
Consumer Electronics: Smartphones, tablets, laptops, and TVs require consistent readability in bright outdoor environments and dim interiors.
Automotive Displays: In-vehicle infotainment, HUDs, and instrument clusters must remain visible in harsh lighting such as sunlight, tunnels, and night driving.
Augmented Reality (AR) & Wearables: AR headsets, helmet visors, and heads-up displays blend digital content with physical environments.
Aerospace & Defense: Cockpit displays, tactical field equipment, and control interfaces require uncompromised readability under extreme lighting conditions.
Medical Devices: Surgical monitors, diagnostic screens, and wearable health technologies must deliver color-accurate, high-contrast visuals in diverse lighting environments, including high-glare ORs and patient settings.
Industrial & Outdoor Systems: Kiosks, point-of-sale systems, and digital signage often operate in high-glare environments such as direct sunlight or warehouse lighting. These applications demand coatings with exceptional anti-reflective and contrast-enhancing properties.
Retail & Showroom Displays: Transparent LCDs used in smart showcases or product displays must balance digital content visibility with the clarity of physical products under controlled but complex lighting.
At the Core of the System
The system’s core utilizes the most current design of Dr. Edward Kelly, a compact modified spherical illumination cavity, delivering uniform diffuse light from all angles. This approach replicates real-world ambient lighting conditions, comprehensively assessing total spectral reflectance and capturing specular and diffuse components with the addition of a dual-channel spectroradiometer to the sphere illumination. Accurate measurement of ambient light spectral reflectance is critical to evaluating and predicting display readability, contrast, and coating performance under practical use conditions.
By simulating real-world environments—where ambient light originates from multiple directions—the GS-291 enables engineers to optimize materials, coatings, and optical stack designs for peak performance in uncontrolled lighting scenarios. Whether refining anti-reflective treatments or improving visibility and color fidelity across a range of ambient conditions, the GS-291 equips you with the data you need to meet stringent performance standards.
