Display Characterization and Production Testing

Display Characterization and Production Testing

At Gamma Scientific, we perform a wide array of display tests to ensure accurate display evaluation and increase the productivity of production. 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 Curved Display - Whether the device utilizes LCD, OLED, micro LED, or Quantum Dot technology, or in a flat or curved form, parameters such as luminance, chromaticity, color gamut, contrast, flicker, uniformity and characterization by different viewing directions are critical. Ultra-high precision Spectroradiometer-based systems, such as the benchtop GS-1290-DMS and compact GS-1160B ensure highly accurate NIST-traceable standards are met. Curved displays can be tested by the fully automated GS-1290-DMS-RBT Robotic system. GS-1164 multi-angle spectroradiometer and VDU-1160 2D spectral imaging colorimeter combines laboratory-grade accuracy and flexibility with high speed and durability for demanding production environments

 

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 380 - 1100 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.
