What Is an LCD Calculator?
An LCD (Liquid Crystal Display) calculator is a device that uses low-power, flat-panel display technology to show numbers and symbols. This technology is the standard for modern calculators due to its excellent readability, low energy consumption, and cost-effectiveness. Calculators with LCDs range from basic models for simple arithmetic to advanced scientific, graphing, and financial calculators designed for specialized tasks in education and professional fields like engineering and finance.
