Descriptions
The LTS-4000A series are 0.4 inch (10.16mm) height
single digit displays. AlGaAs red displays has gray face
and white segments. Bright red displays has black face
and red segments. Green and yellow displays have
gray face and white segments. Red orange displays has
orange face and orange segments. The high efficiency
red displays have red face and red segments.
The AlGaAs red seven segment displys are designed
for applications requiring low power consumption. They
are tested and selected for their excellent low current
characteristics to ensure that the segments are
matched at low current. Drive current as low as 1 mA
per segment is available.
The AlGaAs red series devices utilize LED chips which
are made from AlGaAs on a non-transparent GaAs
substrate. The bright red and green series devices uti-
lize LED chips which are made from GaP on a transpar-
ent GaPsubstrate. The yellow and red orange series
devices utilize LED chips which are made from GaAsP
on a transparent GaP substrate. All devices have gray
face and white segments.
