It was on May 15, 1973 that Sharp released the EL-805 LCD calculator, starting a revolution in electronics. Until then, calculators used fluorescent character display tubes or light-emitting diodes. Using LCD for the number display meant that power consumption was cut dramatically - to a mere 1/100th of previous calculators. This astonishing leap in energy efficiency gave users 100 hours on one AA battery. Sharp's unique silver-coloured COS-LCD display was three years later replaced with the EL-8020 by the common yellow-screen FEM-type display.

The first LCD calculator sold by Texas Instruments could be found in the TI-1750.
