6.3.4 Manual Brightness Mode

For manual brightness mode, apply a 0-5V input voltage to the DIM pin on the dimming control connector. The DIM input will override any input from the photodiode board. Note that the photodiode board may be left disconnected if not used.

The LC1200R brightness vs. DIM voltage relationship is Figure 10. 1.5V will dim the LC1200R to below 100 nits; and above 3.5V will produce maximum brightness.

Note: At extremely low brightness levels, non uniformity and flickering may become evident.
