Note1 Definition of viewing angle
Viewing angle is the measurement of contrast ratio®R10, at the screen center, over a
180° horizontal and 180° vertical range (off-normal viewing angles). The 180° view-
ing angle range is broken down as below: 90° (θ) horizontal left and right, and 90°
(Φ) vertical high (up) and low (down). The measurement direction is typically perpen-
dicular to the display surface with the screen rotated to its center to develop the
desired measurement viewing angle.
