| titleOfInvention |
Measuring device for detecting optical properties of an electro-optical display |
| abstract |
The invention aims to simplify the design of the known conoscopic measurement devices (10) used for determining the viewing angle-dependent contrast in particular of transmission-operated liquid crystal displays, and to calibrate such a measurement device spectrographically and make it more versatile. This is done according to the invention by dispensing with the conventional projection optics (for forming an image of the interference pattern on a detector array) and making use instead of relatively few individual rapid detectors (18) for spectrally integrating and/or spectrally analysing light measurement. These detectors are connected, directly or as directly as possible via optical waveguide devices (20) in the interference plane to point surface elements in the interference pattern selected according to the angle of view. When optical waveguides (20, 20') which branch off to different detectors are connected, completely different direction-dependent measurements can be made and recorded at precisely the same time and for identical angles of view, as can (in addition to the contrast measurements) saturation measurements and measurements of dynamic switching characteristics. |
