Note1: Please drive with constant current.
Note2: The
Luminance uniformity
may be changed depending on the current variation between 4 circuits.
It is recommended that the current value difference among the circuits be less than 5%.
4.3.3 Power supply voltage ripple
This product works, even if the ripple voltage levels are over the permissible values as the following
table, but there might be noise on the display image.

Note1: The power supply’s rated current must be more than the fusing current. If it is less than the
fusing current, the fuse may not blow in a short time, and then nasty smell, smoke and so on
may occur.
