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-colored COS-LCD display was three years
later replaced with the EL-8020 by the common yellow-screen FEM-type
display.
The
EL-8010 was together with the EL-8010S, EL-8015 and EL-8110 one of the last calculators using the
silver-colored COS-LCD display.The first LCD calculator sold by Texas Instruments could be
found in the TI-1750.
