Answer:
LEDs (Light Emitting Diodes) are the only ones that radiate emissions.
Explanation:
LED stands for Light Emitting Diode, which is a semiconductor device that emits light when an electric current is applied to it. On the other hand, LCD stands for Liquid Crystal Display, which is a type of flat panel display that uses liquid crystals to produce images.
LED emits light while LCD uses a backlight to illuminate the screen. Therefore, LEDs are the only ones that radiate emissions.
Summary:
- LED emits light when an electric current is applied to it.
- LCD uses a backlight to illuminate the screen.
- LEDs are the only ones that radiate emissions.

LED light emitting diode- it emits photons when excited by a dc source.
LCD does polerize light passing through them. they are incapable of producing light by itself. that's why every LCD screen employs a backlight.
