| 2.0 inch ( 50.80mm ) 4X4 DOT MATRIX LED DISPLAY DESCRIPTION The UVP-2X44 is 2.0 inch (50.80mm) height 4X4 dot matrix display. UVP-2X44 SERIES 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. FEATURES l l l l l Industuy standard size Wide viewing angle Continuous uniform dot matrix.
