It seems that HP was using a line of 3 LED ships for the display.
Each chip is displaying 5 digits.

It is still possible to source HPDL 1414 chips , however they display only 4 digits each ...
And i did not found any of the 5 digits version as New Old Stock yet.

The HP-97 has a 15 digit display module. Digits 1 and 13 only have a "g" segment because they only need to display a negative mantissa and/or exponent.
