Panel Specification
Note 1: Measurement method
The LCD module should be stabilized at given temperature for 30 minutes to avoid abrupt temperature
change during measuring (at surface 35 ). In order to stabilize the luminance, the measurement should be
executed after lighting Backlight for 30 minutes in a stable, windless and dark room.
Note 2: Definition of viewing angle measured by ELDIM (EZContrast 88)
Viewing angle is the measurement of contrast ratio 10, at the screen center, over a 180° horizontal and
180° vertical range (off-normal viewing angles). The 180° viewing angle range is broken down as follows;
90° (θ) horizontal left and right and 90° (Φ) vertical, high (up) and low (down). The measurement direction is
typically perpendicular to the display surface with the screen rotated about its center to developthe desired
measurement viewing angle.

Note 3: Contrast ratio is measured by TOPCON SR-3
Note 4: Definition of Response time measured by Westar TRD-100A
The output signals of photo detector are measured when the input signals are changed from “Full
Black” to “Full White” (rising time, TrR), and from “Full White” to “Full Black” (falling time, TrF),
respectively. The response time is interval between the 10% and 90% (1 frame at 60 Hz) of
amplitudes.
TrR + TrF = 5 msec (typ.).
