					LCD vs. Plasma vs. LED Televisions
When choosing a new flat-panel television, it is no longer just about brand name recognition. It is about deciding between three technologies: LCD,
Plasma or LED. All of these can deliver an outstanding picture but there are differences when it comes to each one. Below are some pros and cons of
each television type. This guide should help you decide which type of television will give you the image quality you are looking for.


LCD (Liquid-Crystal Display)


 LCD televisions implement liquid crystals that align themselves when activated by an electrical current. An LCD display has a light source behind the
pixels that allow the picture to be shown on the screen. LCD flat screen televisions are versatile and can be installed on a wall with the appropriate
mounting equipment. Unlike a Plasma television, LCD panels require less power to operate and there is no radiation emitted from the screen itself. An
advantage to an LCD television is that it is not susceptible to burn-in, it runs cooler with less screen glare and it has a longer display life.


Pros:        Longer screen life         Better glare response    Less power consumption     High contrast images       Thin display    Light weight for easy
installation
Cons:          Ghosting, which is a moving image that has tail following it on screen      Lower contrast ratio     Individual pixels could burn-out   Moving to
either side will diminish picture quality Plasma


 Plasma televisions are made up of xenon and neon gases. Plasmas typically have a better picture than an LCD. Not only do they have a brighter
picture, but they also process motion faster. They have a better contrast ratio, more color depth and the availability of larger screen sizes that an LCD
television. It has a better picture quality in normal or low room lighting compared to the LCD. The color quality and uniformity matches that of a movie
theater, so if you would like to simulate the typical movie theater experience, a plasma television is the way to go. Just like an LCD screen,
plasma’s are capable of display high-definition TV, regular TV and home video.


Pros:        Higher contrast ratio         Fast screen refresh rate   Wide viewing angle   More color depth       Available in larger sizes   Thin display
Long life span Cons:            Image retention or burn-in      Generate more heat    Do not perform well in high altitudes     Heavier LED (Light-Emitting
Diode)


The newest form of television technology is the LED. LED is the latest form of the LCD television, but it has superior definition display in comparison
to the traditional LCD television. It enables a true-to-life range of picture brightness that an LCD television is incapable of reproducing. There are
different types of LED technology that are used in LCD TV’s. One is edge-lighting, where LED backlights are placed along the outer edges of
the screen. The other type is referred to as full-array. Several rows of LEDs are placed behind the surface of the screen.


Pros:        Lower power consumption             More balanced color saturation   Better lifespan   Smooth picture      Thinner than Plasma or LCD screens
Cons:        Cost As you can see, there are similarities when it comes to each television, as well as pros and cons for each technology. When deciding
on a television display, make sure you keep in mind exactly what it is you are looking for and compare each model.
