Note 2: Test equipment setup:
After stabilizing and leaving the panel alone at a driven temperature for 10 minutes, the measurement
should be executed. Measurement should be executed in a stable, windless, and dark room. Optical
specifications are measured by Topcon BM-7orBM-5 luminance meter 1.0° field of view at a distance
of 50cm and normal direction.

Note 3: Definition of Response time:
The response time is defined as the LCD optical switching time interval between “White” state and
“Black” state. Rise time, Tr, is the time between photo detector output intensity changed from 90%to
10%. And fall time, Tf, is the time between photo detector output intensity changed from 10%to 90%

Note 4: Definition of contrast ratio:
The contrast ratio is defined as the following expression.
C on trast ratio (C R ) =
L u m in an ce m easu red w h en L C D on the "W hite" state
L u m in an ce m easu red w h en L C D o n the "B lack " state
Note 5: White Vi = Vi50 ± 1.5V
Black Vi = Vi50 ± 2.0V
“±” means that the analog input signal swings in phase with VCOM signal.
“±” means that the analog input signal swings out of phase with VCOM signal.
The 100% transmission is defined as the transmission of LCD panel when all the input terminals of
module are electrically opened.
Note 6: Definition of color chromaticity (CIE 1931)
Color coordinates measured at the center point of LCD
Note 7: Measured at the center area of the panel when all the input terminals of LCD panel are
electrically opened.
