Q7T3-FP737S-Dual function LCD Monitor Service
Measurement is done on position 1.
Viewing angle origine is the axis normal to the flat panel. Left (L) and Right (R) value
are the maximum angles for which CR=10. Up (U) and (D) value are the maximum
angles for which CR=10.
See figure below
Ö = 180 , Left
3.Contrast Ratio (CR) is defined mathematically as:
4. Response time
TrR measures the transition time of L1 relative luminance from white to black state, from 90% to 10% (see graph
below)
TrD measures the transition time of L1 relative luminance from black to white state, from 10% to 90% (see graph
