DESCRIPTION
The UVS-312A/313A/315A is 0.3 inch (7.62mm) height single digit display.
Choices of five colors-high efficiency red/bright red/green/yellow/red orange.
High efficirncy red displays has red face and red segments. Bright red displays has black face and red segments.
Green and yellow displays have gray face and white segments.Red orange displays has orange face and orange segments.
The bright red and 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.
