Note 1,7
Note 1: Definition of optical measurement system.
The optical characteristics should be measured in dark room. After 5 Minutes operation, the optical
properties are measured at the center point of the LCD screen. All input terminals LCD panel must
be ground when measuring the center area of the panel.
Note 2: Definition of viewing angle range

Note 3: Definition of contrast ratio
Note 4: 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 ON ) is the time between photo detector output intensity changed from
90% to 10%. And fall time (T OFF ) is the time between photo detector output intensity changed from
10% to 90%.
Note 5: Definition of color chromaticity (CIE1931)
Color coordinates measured at center point of LCD.
Note 6: Definition of Luminance Uniformity
Active area is divided into 9 measuring areas (Refer Fig. 2). Every measuring point is placed at the
center of each measuring area.
Luminance Uniformity (U) = Lmin/ Lmax
L-------Active area length W----- Active area width
Lmax: The measured Maximum luminance of all measurement position.
Lmin: The measured Minimum luminance of all measurement position.
Note 7: Definition of Luminance:
Measure the luminance of white state at center point.
