02 \\ umiTop technology and L customization Central to the LumiTop technology is the speed and resolution of a high-performance camera and the unsurpassed accuracy of a fast high-end array-spectroradiometer, acting as a live reference. Simultaneous acquisition of the reference spectrum and the camera image of the entire display lay the foundation for outstanding optical quality tests in demanding takt times and uncompromising accuracy, traceability and 24/7 production performance. Customized for lab and production demands The diverse demands of production and labs are met by LumiTops...

Our auditing light sources are very accurately defined light sources traceable to national metrology institutes (NMIs). Regular audit of LumiTop measurement instruments against those light sources guarantees absolute measurement accuracy at any time and at any production site throughout the supply chain. This assures the same high display quality of the product no matter where and when it is produced. Moreover, our auditing tools are optimized for quick inline instrument checks that minimize factory downtimes. Local partners and service subsidiaries ensure swift response and provide rapid...

y amma correction is important to adapt the G displays luminance curve to the non-linear (intensity) perception of the human eye. Instrument Systems’ LumiTop provides customizable gamma tests, enabling even fast one shot gamma measurements. y LED and other modulated light sources can O produce visible artefacts due to a mismatch of exposure time and refresh rate. Using the fast, integrated photometer to determine the exact modulation frequency, LumiTop easily synchronizes the camera measurement to avoid such artefacts. Furthermore, the integrated hardware trigger also allows synchronization...

04 \\ Augmented and virtual reality (AR/VR) testing LumiTop AR/VR brings speed and absolute photometric accuracy to near-eye displays! Instrument Systems AR/VR lens for LumiTop imaging colorimeters is specifically designed for production testing of near-eye displays (NEDs) in virtual and augmented reality headsets. The optical design mimics the human eye and measures color and luminance exactly as seen by the user. A large field of view, various pupil sizes and adjustable focus distance enable a wide range of testing applications. A unique periscope design facilitates easy access to the...

05 \\ LED wafer and array testing LED-based light sources have largely superseded conventional light sources. Due to their technical advantages, they have given rise to many new exciting applications. In particular, upcoming µLED technologies are expected to drive displays in head-mounted devices for augmented and virtual reality applications and other mobile devices. Each LED in the millions of pixels on a wafer is a single light source with individual variations in color and luminance. To assure the highest quality under the constraints 2D testing of µLED wafers With millions and millions...

With the advent of µLEDs each of the millions of pixels on a display is an individual light source with individual variations in color and luminance. To produce high-quality uniform displays, these variations must be tested, corrected, and kept below visual noticeability. To assure the highest quality under economical takt time constraints, fast and accurate optical testing has to be provided for every pixel on the entire display. The LumiTop X150 system from Instrument Systems provides ultrahigh-resolution images of displays, where each DUT pixel is oversampled sufficiently by many camera...

07 \\ Automotive Displays are becoming more and more prevalent in the automotive cabin and must serve a variety of functions flawlessly in a challenging environment. Specialized analysis to measure effects such as Black Mura must be conducted according to established standards; this enables meaningful comparison between supplier and manufacturer. The automotive OEM software features of the LumiSuite contain tools specially developed for the evaluation of automotive displays and conforming to the standards of the DFF automotive OEM working group. These features include Black Mura, detection...
