Display testing at high and low luminance levels
Instrument Systems cameras suit homogeneity measurements and error detection under special lighting conditions
Instrument Systems has developed the new LumiTop X20 and LumiTop X30 imaging colorimeters for homogeneity measurements and error detection under special lighting conditions.
The human eye adapts easily to dark and bright lighting conditions. Modern displays take this into account by dimming their display to low luminance when needed to relieve the viewer’s eyes. When designing and manufacturing displays, the luminance and colour of the display must therefore be accurately tested, even at low luminance. Typically, these tests are performed at low luminance levels ranging from 0.001 cd/m2 to 0.1 cd/m2.
The LumiTop X20 and X30 feature high camera resolution (20 MP and 31 MP respectively) and improved dynamic range from 10-3 to 106 cd/m². Using them, Instrument Systems says display manufacturers are able to perform tests at very high luminance in the range of several Mcd/m² as well as low luminance in the range of 0.001 cd/m2 to 0.1 cd/m2, taking into account the adaptation of the human eye to dark and bright lighting conditions.
