Flat displays
LD-001 Series
The LD-001 series were designed in
response to the need for medium-sized, flat
displays. These are two-chip, flat displays
with high luminance.

!Operation notes
When forming leads, the bend should be at least 2mm from the base of the package. Solder after forming the leads, and
ensure that the inside of the LED is not subjected to mechanical stress while it is hot.
