Are you going to buy a new TV that must be a style icon too? Are you not sure which one to buy amongst a Plasma and an LCD TV? Plasma charms you, but LCD is much more affordable. Before making a decision, it is important to know what the differences between both the devices are, and how they differ from each other in terms of working.
What is Plasma TV?
It is a plane and flat panel display, used for huge screens mostly. These displays are brighter and more vivid than LCD displays due to difference of working and substances used in them.
Working of a Plasma TV:
There are two plates of glass used in Plasma’s working which hold innumerable tiny cells within. These cells are full of two gases; neon and xenon. Between the glass-plates on both sides of these tiny cells, there are placed long electrodes. A potential difference is caused by charging these electrodes. When a difference in voltage happens, ionization of neon and xenon occurs and creates plasma. These ions start moving towards the electrodes resulting in collisions, which give birth to photons.
The pixels of Plasma display consist of three sub pixel cells which are red, blue and green colored phosphors. Variation in the current which flows through these phosphors increases or decreases the intensity of these colors. This is the reason behind rich color display of Plasma TV.
What is an LCD TV?
Liquid crystal display; LCD display consists of two glass-plates holding inside them an arrangement of liquid crystals.
Working of an LCD TV:
Two glass-plates hold thousands of pixels filled with liquid crystals, and there is a source of light at the back. There are two transparent electrodes and two polarizing filters also; between them is present a layer of molecules. Liquid crystal molecules are lined up in a certain direction before an electric charge is applied to them. When an electric charge is applied, variation results in construction of different levels of grey.
Same three colored sub pixels are present in LCD too. Colors are subtracted from white light and thus, color elements are displayed.
Plasma vs. LCD:
- Plasma has a larger display than LCD.
- Plasma displays better contrast ratio, enhanced color accuracy and deeper blacks.
- Plasma can produce large sized and brighter pictures as compared to LCD.
- There is no light source in Plasma; rather every pixel produces its own light.
- Plasma displays better motion tracking capabilities than LCD; which smudges the moving objects sometimes.
- Plasma Displays are prone to burn-ins whereas LCD has no such threat.
- Single pixels of LCD can burn-out.
- LCD consumes about 25% less power than Plasma.
- LCD is much more affordable than Plasma TVs.
Here is the comparison between both technologies with their pros and cons. Now, the decision is up to you solely.
