Abstract:
A test system for producing quantitative visual test data for a group of flat panel displays to allow objective comparisons of visual quality between each of the flat panel displays, the system comprising:a test device for performing a plurality of quantitative photometric tests on each flat panel display; a rotatable means for varying a viewing angle between the test device and a plane of a display under test, including a first turning element attached to the display under test, the first turning element operable to rotate the display under test about a vertical axis; and a second turning element attached to the display under test, the second turning element operable to rotate the display under test about a horizontal axis; wherein the test device measures the display under test at varying viewing angles; and a computer for calculating a photometric index for each of the quantitative photometric tests for each flat panel display, each photometric index providing an objective measure of the visual quality of each flat panel display; and producing a report comprising the plurality of photometric indices of each flat panel display.
