Note 5: Definition of response time:
The output signals of photo detector are measured when the input signals are changed from “White” to “Black”
(falling time) and from “Black” to “White” (rising time), respectively. The response time interval is between 10% and
90% of amplitudes. Please refer to the figure as below.

Note 6: 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 below: 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 to its center to develop the desired measurement
viewing angle.
