Plasma screens are made of two glass panels. The panels house thousands of gas chambers, each behind red, blue, and green phosphors. An electrical current is used to turn the gas into plasma, which generates an ultraviolet light that causes the phosphors to glow, creating the desired image.
Plasma screen advantages and Disadvantages
What are the advantages of Plasma?
Greater contrast ratio
- A television’s contrast ratio is a measure between the darkest and lightest colours outputted. Plasma televisions frequently boast far higher contrast ratios than LCDs and so are able to display deeper blacks.
- As Plasma technology is widely believed to more suitable for larger size televisions there is a wider range of large, 40 inch plus Plasma televisions available in comparison to LCD offerings.
- As the pixels on Plasma televisions produce their own individual light, Plasma televisions boast higher viewing angles. This is ideal if you will not always be viewing the television from directly in front of it.
What are the disadvantages of Plasma?
- Plasmas, unlike LCD screens, are susceptible to screen burn in. This occurs if the same image is displayed for a prolonged amount of time, causing an outline of the image to be permanently burnt into the screen.
- Plasma televisions typically require much more electricity than an LCD television since instead of a using a fluorescent backlight like in an LCD, Plasma TVs require than each individual pixel is illuminated.
- Plasma televisions tend to output in resolutions of 1024x728 and then use internal scalars to display high definition resolutions of 720p or 1080p. LCD televisions often use these HDTV resolutions natively.
