POWER SUPPLY DESIGN
(1) Ripple voltage of the supply voltage
Please note that the ripple at the input connector of the module should be within the values shown in this table.
If the ripple would be beyond these values, the noise might appear on the screen.

Acceptable range
≤
100 mVp-p
≤
200 mVp-p
Note
The acceptable range of ripple voltage includes spike noises.
Example of the power supply connection to minimize the ripple voltage
a) Separate the power supply
b) Put the filter

(2) Current wave in the luminance control mode
In the luminance control mode, the rush current below flows into the inverter of the module. The duty cycle
varies from 100% through 20% depending on the luminance control level. This might cause the noise on the
screen. Please evaluate the appropriate value of the capacitor in the filter to eliminate the noise.
