Differences: LCD vs LED vs Plasma vs OLED vs Smart TV

Differences between LCD vs LED vs Plasma vs OLED vs Smart TV

Following are the differences between LCD, LED, Plasma, OLED and Smart TV. Simply click on the respective pane below to reveal the differences:

What is it?
LCDLCD is a TV technology
LEDLED is a TV technology
PlasmaPlasma is a TV technology
OLEDOLED is a TV technology
SmartSmart TV is a TV that could be built based on any of the following technologies: LCD, LED, Plasma, OLED
Thickness
LCDMinimum 1 inch
LEDLED edge backlit LCD TVs are thinner than CCFL LCD TVs. Often less than 1 inch.
PlasmaMinimum 1.2 inches
OLEDOLED TVs are thinner than LED TVs (hence all other TVs) because of the size of their diodes
SmartMinimum 1 inch
Power consumption
LCDRequires less power to operate when compared to plasma, but more than OLED TVs
LEDLED-lit LCD TVs consume less power around 70% compared to plasma TVs.
PlasmaConsumes slightly more power than an LCD TV. Modern plasma displays receive high Energy Star (US) ratings.
OLEDRequires less power than an LCD or Plasma TV
SmartVaries as per the TV technology used i.e. Smart LCD, Smart LED, Smart Plasma, or Smart OLED
Screen size
LCD13 – 65 inches
LEDUp to 90 inches
Plasma32 – 63 inches
OLEDUp to 65 inches
SmartUp to 98 inches
Burn-in or Stuck Pixels
LCDNot an issue, but can have a “retained pixel charge” which may also produce ghosting. Stuck pixels are also possible with an LCD display
LEDBurn-in is very rare
PlasmaBurn-in is rare on newer plasma TVs with anti-burn-in features / technologies such as ‘pixel orbitor’. This problem did exist in old plasma TVs as they suffered from burn-in produced by static images.
OLEDBurn-in is unlikely, but OLED TVs are susceptible to burn-in if TV is abused.

Life span
LCD50,000 – 100, 000 hours
LEDAround 100,000 hours
PlasmaAround 30, 000 – 60,000 hours
OLEDRecent improvements allow up to 43,800 hours
SmartVaries as per the TV technology used i.e. Smart LCD, Smart LED, Smart Plasma, or Smart OLED
Viewing angle
LCD“Up to 176°, Picture suffers from the side; There is always a “sweet spot” which will produce brighter, higher contrast images
LEDThe brightness and color on LCD TVs shift noticeably over the screen and depending on viewing angle; Work equally well in dark or brightly lit rooms.
PlasmaPlasma TVs look the same from almost any angle; Work well in dimly lit rooms which is great for watching movies.
OLED170 degree viewing angle

Backlight
LCDYes
LEDYes
PlasmaNo
OLEDNo
SmartVaries as per the TV technology used i.e. Smart LCD, Smart LED, Smart Plasma, or Smart OLED
Contrast Ratio
LCDUp to 15000:1 (not as good as Plasma)
LEDOffer mega contrast ratios — the brightest white to the darkest black a TV is capable of producing.
PlasmaBetter than LCD TVs; Offer high contrast ratios, gorgeously saturated colours, and allow for wide viewing angles
OLED65000:1 – 1,000,000:1
SmartVaries as per the TV technology used i.e. Smart LCD, Smart LED, Smart Plasma, or Smart OLED
Weight
LCDLCD TVs weigh less than comparably sized plasma TVs.
LEDLighter compared to plasma TV
PlasmaHeavier compared to LED-lit LCD TV; May need additional supports to be mounted onto a wall.
OLEDNo
SmartVaries as per the TV technology used i.e. Smart LCD, Smart LED, Smart Plasma, or Smart OLED
Brightness and colour
LCDLCD TVs can often look better in ‘real-world’ situations.
LEDBrighter than plasma or OLED
PlasmaNot as bright as LED-lit LCD.
OLED
SmartVaries as per the TV technology used i.e. Smart LCD, Smart LED, Smart Plasma, or Smart OLED
Screen Thickness
LCDAs thin as 2 inches deep.
LEDThinner than LCD, plasma
PlasmaAs thin as 3 inches deep.
OLED
SmartVaries as per the TV technology used i.e. Smart LCD, Smart LED, Smart Plasma, or Smart OLED
Energy Use
LCDMuch greater
LEDLess for dynamically backlit LCD TVs, about as much for statically backlit ones.
PlasmaGenerally more
OLEDLess
SmartVaries as per the TV technology used i.e. Smart LCD, Smart LED, Smart Plasma, or Smart OLED
Screen Refresh Rate
LCDLCD TVs were originally designed for static data display, nd not moving video. LCD TVs are now available with refresh rates specified by manufacturers as low as 5ms.
LED60-240 Hz, but LCD response times create blur and ghosting which limits true refresh rates to 20-100 Hz.
PlasmaUp to 600 hz. Plasma TVs handle rapid movements in video about as well as old CRT TVs.
OLED
SmartVaries as per the TV technology used; Different for Smart LCD, Smart LED, Smart Plasma, Smart OLED
Performance in extreme conditions
LCDLCD TVs are not affected by high altitudes
LEDLow temperatures (below 50°f) can cause contrast to decrease
PlasmaHigh altitudes (above 6500 ft) can affect the performance of plasma TV displays because the gas held inside each pixel is stressed, and has to work harder to perform.
OLED
SmartVaries as per the TV technology used; Different for Smart LCD, Smart LED, Smart Plasma, Smart OLED
Running Temperature
LCDThey radiate less heat in general
LEDDynamically lit LCD TVs dissipate less heat compared to plasma TVs, LED-lit LCD TVs dissipate less heat than even other LCD TVs.
PlasmaPlasma TVs generally dissipate more heat than LCD TVs
OLED
SmartVaries as per the TV technology used; Different for Smart LCD, Smart LED, Smart Plasma, Smart OLED
Screen glare
LCDDoes have glare; Need to use Anti-Glare TV Protector to fix the issue
LEDAntireflectively coated (matte finished) LCD TVs have less glare than glossy LCD TVs.
PlasmaPlasma TVs have more glare than LCD TVs in brightly lit environments due to their thick front glass’s internal reflections
OLED
SmartVaries as per the TV technology used; Different for Smart LCD, Smart LED, Smart Plasma, Smart OLED
Mechanism
LCDBacklight covered by a layer of liquid crystals
LEDUse Light Emitting Diodes (LEDs) to create the images on the screen.
PlasmaThey use small cells containing electrically charged ionized gases, which are plasmas.
OLEDOrganic Light emitting diodes

Motion lag
LCDNot an issue
LEDNot an issue
PlasmaNot an issue
OLEDToo early to tell

Durability
LCDSomewhat more durable than older plasmas. End users can easily mount an LCD TV themselves if desired, although LCD TVs should still be shipped with special care, and the screen itself should be cleaned with
a streak free cleaner
LEDSimilar to LCD
PlasmaPlasmas are somewhat fragile making them tricky to ship and install. Unlike the commercials where plasmas are mounted on the ceiling, plasmas are best installed by a professional. However, recent improvements to plasma screens have made them significantly more durable and lighter weight.
OLEDNo

Shipping
LCDShipping LCD TVs is not difficult, and is not as expensive as shipping plasma displays.
LEDSimilar to LCD
PlasmaDue to their fragile nature, plasma TVs need to be shipped by specialty carriers. Overnight or fast delivery options are not recommended. Special shipping methods and their heavier weight add to higher shipping costs.
OLED
SmartVaries as per the TV technology used; Different for Smart LCD, Smart LED, Smart Plasma, Smart OLED
Installation
LCDEnd users can easily install LCD TVs themselves, or can use them just as they use a traditional TV using a stand.
LEDEasy to wall-mount, and movable from one room to another.
PlasmaPlasmas are heavier, use more power, and run hotter than LCD TVs, and therefore require more planning when mounting them. Plasmas are generally best installed by professionals.
