The company Panasonic has just introduced officially in Japan a new plasma TV capable of displaying three-dimensional images. The screen size is of no less than 103 inches, so with that size clearly supports FullHD.
This TV comes with a Blu-Ray player that distributes different images of high-definition (1080) to the left and right eyes, so that the two images together our brain perceives what we like in three dimensions. However it is necessary to resort to the classic 3D glasses to get the full effect, not just look directly thismega-screen .
Of course to take advantage of this technology is essential that the images were created in 3D, so we can not see any old film in three dimensions even Blu-Ray. As virtually no "material" (films) for this technology Panasonic has created a series of content for demonstration. It has also begun to enter into negotiations with Hollywood studios to standardize 3D images on Blu-Ray. We'll see how it evolves this topic, but I think I am right in saying that this technology will be very expensive. Is it worth?
After studying the basic operation of LCD TVs, we look at how to generate images of Plasma TVs, because we can better understand the differences between the two technologies, and why then will choose one or the other technology as best in different specifications. Everything comes from its operation.
But how does a plasma TV? Well, oddly enough, and unlike LCDs, work similarly to traditional CRT TVs. At least on the issue of generating light matches.
In plasma TVs start from glass panels divided into cells that contain a mixture of noble gases when electrically http://vimeo.com/54063084 excite becomes plasma and matches begin to emit light. This is the main difference with LCD TVs. For plasmas, the light contain them, not from elsewhere, as with the backlight of LCD TVs. This gives us immediate results the main feature of plasma TVs: the intense black getting still unattainable for LCD technology.
Plasma TVs are also formed by pixels. In turn, each pixel has three separate cells in each of which there is a different color phosphor red, blue and green. These colors blend together to create the final color of the pixel.
The operation matches through plasma screens, offers a number of advantages (better contrast and fast response time) but also are the source of its main drawbacks. Thus, the technology being based on phosphorus, prolonged exposure of a still image for a long period of time can cause a marked on the screen very annoying. If always marked tendency to the same area, it may cause a so-called screen burn-in.
In addition, matches tend over time to run out and shut down, leaving us with a life time of plasma screens smaller than in the case of LCD technology, as discussed in the comparison. The decrease in image quality is often progressive.
Finally say that due to the operation of which is based on plasma gases, altitude affects them directly, but should not be the case for the vast majority, watch plasma TVs because at high altitudes may even not work.
