5X7 DOT MATRIX LED DISPLAY
UVP-4X57XX SERIES
DESCRIPTION
The UVP-4057/4157 4257AA/4357AA is 4.0 inch (101.6mm) height 5X7 dot matrix display.
Single color display have the choices of three bright colors-AlGaAs red/green/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.
And red orange LED chip are made from GaAsP on a transparent GaP substrate.
