This could certainly be the case for the TI calculators, I'm not sure.

In the HP LED models the display can be blanked but the processor execution speed does not change. This is because each display digit is refreshed during one instruction execution (56 system clock cycles) . So even when the display "flickers" during calculations or running programs, the speed still stays the same.
