Speedcafe.com understands the displays are being evaluated for a potential introduction next season as part of the Gen3 ruleset.
Key in the evaluation is the visibility of the LED panels for timekeepers, who still perform a manual back-up.
They could be used to display the position of cars while on track, with a number of other features able to be programmed in.
Should the panels be used to show the number a car is entered under, it would need space for three digits.
In this year's Great Race, three cars are entered with a triple-digit competition number (#100, #118, and #888).
LED information panels were set to be rolled out in the 2020 Supercars Championship, though supply chain issues put paid to that.
