LCD TV vs Plasma TV.

Hello friends,
Do you know which is better between these two. Both are looking same but under the bonnet the technology driving LCD TVs is very different from that driving Plasma TVs. These are the different between these two model. just look below.


A plasma display consists of two plates of glass, sandwiched between which are hundreds of thousands of tiny, gas filled cells. These cells are rather like tiny flourescent tubes as they are filled with neon gas and coated with phosphor.
Each plasma cell can be individually energised with an electric current. This causes the gas to release ultraviolet photons. These photons cause the phosphor coating of the cell to radiate visible light. If the cells are switched on and off in the correct sequence, the picture is formed. This switching happens 1000s of times a second.
These gas filled cells form the pixels of the display. In fact, each pixel consists of 3 cells, giving off red, green or blue light. By varying the relative intensities of red, green and blue, different colours are formed.


The pixels of an LCD TV dislay, unlike those of a Plasma display, do not give off any light themselves. A liquid crystal solution is trapped between two sheets of glass and the whole display is illuninated with a back light. The voltages applied to the various pixels is varied and this controls how much light from the back light reaches the screen. In turn, the pattern of light reaching the screen forms the picture.

Whis is better - LCD vs Plasma?
Traditionally, Plasma tvs have had the edge over LCD tvs, particularly at larger screen sizes. This difference is diminishing all the time, however, as LCD technology moves forwards. Prices are generally coming down and the price difference between the two is getting less. Performance-wise the difference is diminishing too. There is a slight issue regarding LCD tvs not displaying deep blacks as well as Plasma, but in general use this difference is becoming negligible.

Plasma never made the transition to 4k.

LCD, while improved, is still no match for the new tech OLED. That's where MY bet is being placed.
