How do plasma televisions work?
A plasma TV display is an array of tiny gas cells sandwiched between two sheets of glass. Each cell acts like a mini fluorescent tube, emitting ultraviolet light which then strikes red, green and blue spots on the screen. These spots glow to build a picture.
Plasma has lost HD TV market share to LCD over the last few years, due largely to many of the key TV manufacturers concentrating efforts on LCD and LED televisions.
Who makes plasma televisions?
Panasonic dominates the plasma TV market. It produces by far the most extensive range of plasma TVs and continues to place plasma at the heart of its TV strategy.
LG and Samsung still produce a handful but largely concentrate their efforts on LCD-based technologies. Other big brands, such as Sony, Toshiba and Pioneer have ceased plasma TV production.
How does plasma picture quality measure up?
Plasma TVs have some key advantages over LCD televisions. They tend to produce deeper blacks and richer colours, have wider viewing angles and typically boast a faster response time. This is the amount of time it takes a pixel to go from black to white and black again, and in theory means the TV should cope with moving images, reducing the chance of blurry or stuttering pictures.
Are plasma TVs the best option for 3D TV?
Thanks to the faster response time of plasma TVs (the amount of time it takes a pixel to go from black to white and back again) in theory they should be the best option for 3D TV.
TVs with slower response times (LCD and LED) are more likely to suffer from double (or ghost) images caused by the images for each eye overlapping ? once you notice them, they?re hard to ignore.
