Note 9: Definition of viewing angle
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.
