Description
The LTP-14X58A series are 1.4 inch (35.76mm)matrix
height 5X8 dot matrix displays.
The LTP-14858AA/14958AA are multicolor applicable
displays.
The multicolor displays have gray face and white dots.
The LTP-14058A/14158A series are single color
displays.
The green, yellow, red orange and AlGaAs red displays
have gray face and white dots.
The green series devices utilize LED chips which are
made from GaP on a transparent GaP substrate.
The yellow and red orange series devices utilize LED
chips which are made from GaAsP on a transparent
GaP substrate.
The AlGaAs red series devices utilize LED chips which
are made from AIGaAs on a non-transparent GaAs
substrate.
Notes : All dimensions are in millimeters(inches).
Tolerance : 0.25mm (0.01") unless other-
wise noted.
