An LCD calculator is a type of electronic calculator that uses a Liquid Crystal Display (LCD) to show numbers and symbols.

What:
An LCD calculator is a portable, battery- or solar-powered device that performs arithmetic and other mathematical functions. It displays the output on an LCD screen, which is a flat, low-power display technology.

Why:

  • Energy-efficient: LCDs consume very little power, so calculators with LCD displays last a long time on small batteries or solar panels.
  • Clear visibility: LCDs provide sharp, clear digits that are easy to read from different angles.
  • Compact and lightweight: LCD screens make calculators slim and portable.

How:

  • Input: You press the buttons for numbers and operations.
  • Processing: The calculator’s microprocessor performs the calculation.
  • Display: The result is shown on the LCD screen by manipulating liquid crystals to form the numbers and symbols.

When:
LCD calculators became popular in the 1970s and quickly replaced older LED (Light Emitting Diode) calculators because LCDs use far less power. By the 1980s, LCD calculators were the standard — and they still are today.
