Optical Features

Viewing Angle

Viewing angles are defined per Figure 10 below:

Figure 10. Viewing Angles.

6 o'clock direction

Response Times

The rise response time (from white to black) is 25 ms typical and the fall response time
(from black to white) is 45 ms typical. This is shown in Figure 11.

Dimming

Initial backlight dimming is performed by decreasing tube current, allowing for
substantially higher tube life in applications that do not require maximum luminance.
The user can adjust the display for the optimum combination of luminance, life, and
power consumption for the target application.
