Summary
| Description | Luminance and contrast versus viewing direction in a polar coordinate system. The left column shows the directional luminance distribution of the dark state of the display (IPS LCD), the center column shows the bright state and the right column shows the (luminance) contrast (ratio) resulting from the preceeding two luminance distributions. The value is coded by (pseudo) colors. The graphs below the polar coordinate systems each show a cross section in the horizontal plane and indicate the values for luminance and for the contrast. Each borderline between two (shades of) colors represents a line of constant value, in the case of contrast an iso-contrast (contour) line. Note, that "iso" is used in the meaning of "equal", it does NOT establish a relation to the International Organization for Standardization, ISO. Measurements were carried out with a ConoScope. |
