Televisione LCD Plasma LED differences
In this post we will focus in particular on the difference between plasma, LCD and LED televisions.
Until a few years ago plasma televisions were the most popular … the best that the new technology could offer, until they were ousted by the first LCD televisions and LED LCD after.
It must be said that even today, however, despite the boom in sales shows that the consumer market is now oriented towards the purchase of LCD TVs, there is a niche of fans who continues to prefer them as they can boast a yield of truly unparalleled colors.
On the other hand, however, plasma televisions also have many limitations that are perhaps the basis of their slow decline, including the price, much higher than direct competitors (liquid crystal TV); a greater thickness that is at the expense of design and space; a lower resistance (they are exhausted after a pre-established number of hours); the annoying ghosting effect, that is the effect on which traces of previously reproduced images are displayed on many plasma monitor models.

The LCD screens, whose acronym stands for Liquid Crystal Display, ie liquid crystal displays are the most widespread nowadays and are based, in fact, on a liquid crystal technology: the images are the result of the orientation of the crystals liquids of which the individual cells forming the screen are composed;
Among the main features and advantages of LCD screens are lightness (much thinner and lighter than both old cathode ray screens and plasma screens); less use of energy and the total absence of electromagnetic radiation. In addition, LCD screens give life to much clearer and sharper images, higher resolutions and a flicker-free display.
Even the LCD screens unfortunately have some disadvantages that particularly concern the diagonal: the light reaches our eye after having passed two stages of polarization, so it is not very wide. Another limitation is the contrast and intensity of black not very pronounced as in this type of screens the black does not consist of the absence of light but in the masking of the backlight that is typical of the LCD models.
LED screens are a particular type of LCD screen distinguished by a different type of backlight, a feature that distinguishes, as already anticipated, all LCD TVs. In particular, to illuminate the panel, this technology uses LEDs instead of lamps as it happens in traditional LCD screens. All this benefits the images: they can count on a wider range of colors and more crystalline colors.
Other advantages of LED screens are lower power consumption and thinner TVs.
Single limit? It’s only the higher price.
