Note4: Definition of Response time
The response time is defined as the LCD optical switching time interval between “White” state and
“Black” state. Rise time (T r ) is the time between photo detector output intensity changed from 10% to
90%. And fall time (T f ) is the time between photo detector output intensity changed from 90% to 10%.

Note6: Definition of Luminance Uniformity
Active area is divided into 9 measuring areas (Refer Fig.5). Every measuring point is placed at the
center of each measuring area.
Luminance Uniformity (U) = Lmin/ Lmax
Lmax: The measured Maximum luminance of all measurement position.
Lmin: The measured Minimum luminance of all measurement position.
L-------Active area length; W----- Active area width
Luminance Uniformity Measurement Locations (9 points)
