4X4 DOT MATRIX LED DISPLAY
UVP-2X44 SERIES
DESCRIPTION
The UVP-2X44 is 2.0 inch (50.80mm) height 4X4 dot matrix display.
Single color display have the choices of three bright colors-AlGaAs red/green/yellow.
Multicolor display are applicable to two colors -green/red/orange.
All device have black 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 yellow and Red Orange LED chip are made from GaAsP on a transparent GaP substrate.
