Note (2) If the PWM control duty ratio is less than 10%, it is difficult to control the brightness linearity.
Note (3) If PWM control frequency is applied in the range less than 1KHz, the “waterfall” phenomenon on
the screen may be found. To avoid the issue, it’s a suggestion that PWM control frequency should
follow the criterion as below.

Note (5) Within the specified PWM control duty ratio range, CMI’s LCD module can pass the following
acoustic noise test. The test condition refers to ISO-7779 and is shown as the following figure.
LED_VCCS = Min., Ta = 25 ± 2 ºC, (D
= 200 Hz, Duty=100%.
PWM
PWM, fPWM) = (Max, Max); (Max, Min); (Min, Max); (Min, Min),
while operating on black pattern with CMI’s own pattern generator. All sound pressure of scanning
band 630Hz - 20KHz should be kept under 20dBA. If lower noise level is required, more technical
discussion is needed.
