Large flat displays
LD-701 Series
The LD-701 series were designed in
response to the need for large, flat displays.
These are three-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.
