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 develop the desired
measurement viewing angle.
