== LED TV vs. Plasma TV ==
Light-emitting diode (LED) and plasma televisions represent two different display technologies that competed in the flat-panel market. An LED TV is a type of liquid-crystal display (LCD) TV that uses LEDs for its backlight.<ref name="ref1" /><ref name="ref2" /><ref name="ref3" /> Plasma TVs function by using small cells containing ionized gas (plasma) to generate images directly.<ref name="ref4" /><ref name="ref5" />

Though both technologies were once popular, production of plasma TVs ceased around 2014, as manufacturers shifted focus to LED-backlit LCD and later OLED technologies. The decline was attributed to factors like the higher manufacturing costs, greater power consumption, and heavier weight of plasma sets compared to the rapidly advancing and more energy-efficient LED models. LED TVs became thinner, brighter, and more affordable to produce.

! Category !! LED TV !! Plasma TV
|-
| '''Display Technology'''
| Uses a liquid crystal display (LCD) panel with a backlight composed of light-emitting diodes (LEDs).<ref name="ref1" /> The LEDs can be arranged along the edges (edge-lit) or directly behind the screen (full-array).<ref name="ref1" />
| Each pixel is a small cell containing a noble gas mixture. When voltage is applied, the gas becomes a plasma that emits ultraviolet (UV) light, which then excites red, green, and blue phosphors to create visible light.<ref name="ref4" />
|-
| '''Black Levels & Contrast'''
| Black levels can be compromised by the backlight, which is always on, allowing some light to leak through. Technologies like full-array local dimming improve contrast by selectively dimming zones of LEDs.<ref name="ref1" />
| Capable of producing deep, uniform blacks because each pixel is self-emissive and can be turned off completely. This results in a high contrast ratio, particularly noticeable in dark viewing environments.
|-
| '''Brightness'''
| Generally produces a much brighter image, making it better suited for well-lit rooms where ambient light can wash out a dimmer screen.<ref name="ref5" />
| Less bright than LED TVs, which can lead to reflections and a dimmer appearance in rooms with significant ambient light.
|-
| '''Motion Handling'''
| Response times can vary. Some models may exhibit motion blur with fast-moving content. Higher refresh rates (e.g., 120Hz) are used to mitigate this.
| Exhibits excellent motion handling with minimal blur due to a very fast pixel response time. This made them a popular choice for watching sports and playing video games.
|-
| '''Energy Consumption'''
| Significantly more energy-efficient, consuming less power and generating less heat. A 42-inch LED TV might use around 64 watts per hour.
| Consumes considerably more electricity and produces more heat compared to LED TVs of a similar size. A 42-inch plasma TV could use about 195 watts per hour.
|-
| '''Screen Burn-in'''
| Not susceptible to permanent image retention or burn-in.
| Prone to both temporary image retention and permanent burn-in, where static images like channel logos could become permanently visible on the screen over time.
|-
| '''Lifespan'''
| Generally has a longer lifespan, with modern LED backlights rated for up to 100,000 hours.
| Early models had shorter lifespans, though later models were rated for up to 100,000 hours to half-brightness.
|-
| '''Physical Design'''
| Can be made very thin and lightweight, especially edge-lit models.
| Heavier and thicker due to the glass construction and technology used.
