5X7 DOT MATRIX LED DISPLAY
UVP-7X7 SERIES
DESCRIPTION
The UVP-747/757 is 0.7 inch (17.22mm) height 5X7 dot matrix display.
Single color display have the choices of three bright colors-AlGaAs red/green/yellow.
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 yellow LED chip are made from GaAsP on a transparent GaP substrate.
