Instrument Systems to Present Advanced Measurement Device for Micro LED and AR/VR Display Applications at Display Week

Instrument Systems, the Munich-based light measurement solutions provider, announced that it will showcase an ultra-high resolution version of its LumiTop targeting Micro LED displays and AR/VR display applications at the Display Week 2019.

According to Instrument Systems, the ultra-high resolution LumiTop model merges a 150 megapixel camera with the high-end spectroradiometer CAS 140D to guarantee test accuracy across the whole image of the camera. The resolution of 150 megapixels thereby allows (sub-) pixel level analysis of complete displays in one single shot, enabling accurate quality control and pixel calibration of OLEDs or Micro LED displays in production lines. The device also allow different test applications to be organized in a single test station including the evaluation of display uniformity, pixel defects, white balance, color gamut, contrast ratio or the measurement of intensity modulations.

For AR and VR devices that are close-fitting to the user’s eyes, screen-door effects and pixel non-uniformities could be easily visible and disturbing to the consumer. The LumiTop series with integrated pixel shift mechanism suppresses de-mosaicing artifacts by true full color measurements and even provides increased resolution of 600 megapixels.

Instrument Systems will show a complete light measurement setup with the high-end array spectroradiometer CAS 140D and the positioning station DTS 140 for high power LED and Micro LED testing. As the entire spectrum is captured simultaneously, very short measuring times can be achieved in the order of milliseconds with highest measurement accuracy. Typical application areas are display production and automotive interior lighting.
