| 0.4 inch ( 10.21 mm ) DUAL DIGIT NUMERIC LED DISPLAYS DESCRIPTION The UVD-432XC/482XC is 0.4 inch ( 10.21 mm ) height dual digit display. Choices of four colors-high efficiency red/bright red/green/red orange. High efficiency red, bright red and red orange display have red face and red segments. Green display has gray face and green segments. The bright red and 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. UVD-4X2XC SERIES FEATURES l l l l l Industuy Standard Size Wide Viewing angle Continuous uniform segments.
