1.2 inch ( 30.42mm )
5X7 DOT MATRIX LED DISPLAY
UVP-1X57A SERIES
DESCRIPTION
The UVP-1257AA/1357AA/1457A/1557A is 1.2 inch (30.42mm) height 5X7 dot matrix display.
Single color displays have the choices of three bright colors-AlGaAs red/green/red orange.
Multicolor displays are applicable to two colors green and red orange.
All device have gray face and white dot.
The AlGaAs red LED chip are made from AlGaAs on a non-transparent GaAs substrate.
The green LED chip are made from GaP on a transparent GaP substrate.
The red orange LED chip are made from GaAsP on a transparent GaP substrate.
