5X7 DOT MATRIX LED DISPLAY
The UVP-2057/2157 is 2.0 inch (50.80mm) height 5X7 dot matrix display.
Single color display have the of choices of three bright colors-AlGaAs red/green/red orange.
Multicolor display 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.
