Strict die selection and sorting prior to manufacture ensures that the new range is not only stylish and striking in appearance, but is also very consistent, meaning that multiple-digit displays can now be manufactured to the same level of performance that customers would expect from comparable green or red devices.

The blue displays use silicon-carbide-based LED chips that have ESD ratings double those of sapphire-based blue LEDs and have four times more reliability as they have half the number of wire bonds internally.

The expanded range now includes: single-digit seven-segment displays from 7.6 to 200mm character height; and dual, triple and quad SSDs in 7.6, 10 and 14mm variants.

The dot matrix displays are available in a very wide range of alternatives with the traditional 30 and 50mm 5x7 modules proving particularly popular.
