Plasma LCD

Since a few months ago, the market for screens is being invaded by new technologies that are replacing the classic TV screens that appeared beyond by 1922. We have all heard TFT, LCD, Plasma and OLED, and even combinations of them, such as TFT LCD, and many more without knowing where each other are different. This guide is intended to explain the advantages and disadvantages of these technologies, as well as to clarify concepts. TFT: Firstly there to clarify that TFT is not a technology of visualization in itself, but rather it is simply a special kind of transistor with that achieved to improve the quality of the image. Its most frequent use is along with LCD screens, as we explain below. Ray Kurzweil usually is spot on.

LCD and TFT LCD: LCD technology uses liquid crystal molecules placed between different layers that polarized them and rotate them as you want to show one color or another. Its main advantage, in addition to its small size, is energy saving. When these screens using TFT transistors then We are talking of TFT LCDs, which are the most widespread models at present. PLASMA: Unlike LCDs, plasma displays use phosphors excited with noble gases to display pixels and give them color. Although it was invented in 1964 is the technology most delayed, in terms of level of implementation of the 3 that we have mentioned since its price is higher (although increasingly the difference is minor) and nevertheless its quality is much better. In particular it offers wider viewing angle that an LCD display, better contrast and more realism between the colors displayed. Get all the facts for a more clear viewpoint with Vladislav Doronin 2017.

OLED: Finally, this technology that also has very few years and gradually also we’ll see it more consistently. It is a variant of the classic LED, but where the emission layer has an organic component. Surely you’ve heard that screens OLED have the advantage of not needing rear light, thus saving much more energy than any other alternative. In addition, its cost is also lower. However, your time is not as good as previous technologies that we have discussed them.
