Display Testing

Display Tests for Lighting Equipment

At Gamma Scientific, we perform a wide array of display tests to ensure your product meets lighting requirements. The types of tests we conduct include:


Testing of Near Eye Displays - Devices including Virtual Reality, Augmented Reality and Head-up displays (AR, VR and HUD) must be tested and characterized by manufacturers and those who integrate, incorporate or purchase them. This may include Research and Development activity, quality control or on the production line.  Applications requiring high quantities of equally performing units may also require test and characterization tools. The GS-1290 NED system provides test capability for a wide variety of parameters including luminance and color uniformity, contrast, pixel / line defects, image virtual distance, field of view, image distortion, resolution and response time. Measurement systems must also be configured in such a manner that they do not introduce error into the measurement process, or unrealistically emulate pupil rotation due to camera design limitations.


Flat Panel and Large Area Displays - Whether the device utilizes LCD, LED, OLED or Quantum Dot technology, parameters such as chromaticity, gamma, white balance, contrast, flicker and uniformity are important to characterize. Ultra-high precision Spectroradiometer-based systems, such as the benchtop GS-1220-DMS system, or the fully automated GS-1290-DMS-RBT Robotic system allow for msec measurement times with superior wavelength and color accuracy from as low as 250 nm all the way to 900 nm.  Slightly less sophisticated, yet still highly precise benchtop and handheld spectroradiometers, such as the GS-1160B benchtop and GS-1160 handheld provide for high value solutions in a compact footprint.


NVIS Compatibility Testing - For manufacturers of military displays and other lighted instrumentation used in conjunction with night vision imaging systems (NVIS) who require their products to conform to MIL-STD-3009, an instrument such as the GS-1290-NVIS enables high-speed spectroradiometer-based testing.  These applications frequently require compliance with MIL-L-85762A and MIL-STD-3009, covering the range of 360-930 nm which requires a high signal-to-noise measurement ratio of 10:1 or greater.  


Display Intensity - If you simply require measurement of a display's luminous intensity in units of nit (cd/m2) or foot-lamberts (fl), luminance meters such as the uNITLL-Mini represent easy-to-use, cost-effective, turnkey solutions.


Choose Gamma Scientific for display tests so you can achieve peace of mind.
