Which of the following displays uses gas to display the image?
The correct answer is D. Plasma. Plasma displays work by passing electrical current through tiny cells filled with noble gases (xenon and neon). The gas ionizes into plasma, which emits ultraviolet light that excites phosphors to produce visible color. OLED uses organic compounds that emit light when…

Explanation
Plasma displays work by passing electrical current through tiny cells filled with noble gases (xenon and neon). The gas ionizes into plasma, which emits ultraviolet light that excites phosphors to produce visible color. OLED uses organic compounds that emit light when electrically stimulated. LED uses semiconductor diodes. CRT uses an electron beam striking a phosphor-coated screen. Only plasma technology relies on ionized gas as the core light-producing mechanism.
