LED vs. LCD: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 20, 2023
LED stands for "Light Emitting Diode," while LCD means "Liquid Crystal Display." Both are screen technologies, but LED uses diodes that emit light, whereas LCD uses liquid crystals to modulate light.

Key Differences

LED stands for "Light Emitting Diode." It's a semiconductor device that emits light when an electric current passes through it. On the other hand, LCD stands for "Liquid Crystal Display." It utilizes a liquid crystal solution sandwiched between two layers of polarized glass.

An LED display creates light directly using tiny diodes. In contrast, an LCD display doesn’t produce its own light. Instead, it relies on an external light source, like a backlight, to produce images.

LEDs generally offer better brightness and color contrast than LCDs. However, LCDs can sometimes offer better viewing angles, making them preferable in certain situations where wide-angle viewing is essential.
