Goniometric characterization of curved displays

DMS 904 – Goniometric characterization of curved displays

The established DMS series of display measurement systems offers many options for the view direction-dependent optical evaluation of displays. They incorporate a motorized positioning unit and a temperature control chamber for testing at -40 to +105 °C. Their equipment enables, for example, measurement of the spectral reflectance under hemispherical direct or diffused illumination, or the determination of contrasts under diverse ambient lighting conditions. The new DMS 904 goniometer was specially developed for larger and curved displays. It has seven motorized axes for automatic measurement, a motorized microscope aperture wheel and an integral alignment camera. The additional X-axis permits decentralized, angle-dependent measurement of displays up to a width of 1.8 m. The enlarged temperature control chamber permits movements in X- and Z-direction and has an interior space of 160 x 60 x 20 cm.

LumiTop X20 and X30 – Display measurements at high and low luminance

A special highlight at Display Week will be a preview of the two new LumiTop models X20 and X30. Compared to the previous proven models in display production, they feature a higher camera resolution (20 MP or 30 MP), flexible field of view and particularly wide dynamic range for high and low luminance measurements. The new flicker electronics are designed for frequencies from 1 Hz to 1 kHz. Both models are optionally available with a motorized focus. Suitable applications are homogeneity measurements and error detection under special luminance conditions.
