Flat displays
LD-603 Series
The LD-603 series were designed in response to the
need for large, flat displays. These are two-chip, flat
displays with high luminance.
!Features
1) 6.8
13.8mm planar emission from two chips
connected in series.
2) High luminance, uniform planar emission
3) Thin outer casing, multiple units can be coupled
together.
4) Four colors are available : red, orange, yellow and
green.

When forming leads, the bend should be at least 2 mm 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.
