Fig. 5

Shape of the display surface determined with a coordinate measurement machine. The PV of 0.54 mm is smaller than those of the shape determined during calibration (see Fig. 4) but is in the same order of magnitude. Distinct accordance of both results is not found. However, the display shape is influenced by temperature, gravity and physical stress. While using the coordinate measurement machine, the display was turned off and positioned facing upwards. During our deflectometric measurements, the display was running and placed upright
