== LCD TV vs. Plasma TV ==
Liquid-crystal-display (LCD) and plasma were two competing flat-screen television technologies in the early 2000s. By 2014, major manufacturers like Panasonic, LG, and Samsung had ceased production of plasma TVs, ceding the market to LCDs.<ref name="ref1" /><ref name="ref2" /> While both offered a significant reduction in size and weight compared to the cathode ray tube (CRT) televisions they replaced, their underlying methods for producing images were fundamentally different.<ref name="ref3" />

An LCD TV uses a backlight to shine light through a panel of liquid crystals.<ref name="ref4" /><ref name="ref5" /> These crystals can be electronically twisted or untwisted to block light or allow it to pass through color filters, creating the pixels that form the image on the screen.<ref name="ref4" /> Plasma TVs, in contrast, are emissive displays, meaning each pixel generates its own light.<ref name="ref1" /> They contain tiny cells filled with a gas mixture.<ref name="ref1" /> When a voltage is applied, this gas turns into a plasma, which emits ultraviolet (UV) light.<ref name="ref1" /> This UV light then strikes red, green, and blue phosphors, causing them to glow and produce a visible image.<ref name="ref1" />

=== Picture Quality ===
The different technologies led to distinct advantages in picture quality. Plasma TVs were often praised for their superior contrast ratios and ability to produce deep, true blacks. Because each pixel is self-illuminating, a plasma screen can simply turn off pixels to represent black, whereas an LCD must try to block the constantly shining backlight, which often results in some light leakage.<ref name="ref1" /> Plasma technology also provided wider viewing angles and better motion response, making it a favorite for watching movies and sports.

LCD TVs, however, held a significant advantage in brightness.<ref name="ref1" /> Their use of a powerful backlight made them much better suited for viewing in brightly lit rooms where the dimmer display of a plasma TV could appear washed out.<ref name="ref1" /> While early LCDs struggled with color accuracy and response times, technological advancements, including the switch from CCFL to LED backlights, narrowed the performance gap over time.

=== Practical Considerations ===
Beyond picture quality, several practical factors influenced the market dominance of LCDs. LCD technology was more energy-efficient, consuming less power and generating less heat than plasma displays. LCDs were also lighter and available in a wider range of sizes, particularly smaller ones, whereas plasma TVs were typically only available in larger screen sizes of 40 inches and above.

Plasma TVs had issues with screen burn-in, where static images could become permanently etched into the screen, although later models incorporated technologies to mitigate this.<ref name="ref2" /> They could also be affected by altitude, with some models producing a buzzing sound at higher elevations due to the pressure difference between the gas inside the screen and the ambient air. Ultimately, the lower manufacturing costs, greater energy efficiency, and higher brightness of LCDs led to their widespread adoption.<ref name="ref1" />
