[Note 3]Brightness Control
1. Analog Dimming
Brightness control is regulated by analog input voltage (0V to 3.3V).

Function
0V: Dark - 3.3V: Bright
[Note] PWM frequency : 275±10Hz
[Note]There is a case that lamp mura may happen, depending on ambient temperature and dimming.
Dimming level should be set according to your evaluation of actual display performance.
(Minimum input voltage 1.4V at below 15 )
2.Pulse Dimming
Pin No.13 is used for the control of the PWM duty with input pulse from 150Hz to 350Hz.

[Note]There is a case that lamp mura may happen, depending on ambient temperature,
in dimming. Minimum dimming level should be set according to your evaluation of
actual display performance. (Minimum duty 60% at below 15 )
[Note]In case of using Pulse Dimming, be careful so that the VBRT signal (Pin 13) doesn’t have glitch.
