In recent months, the market for displays is being invaded by new technologies that are replacing traditional TV screens that appeared back in 1922. We’ve all heard of TFT, LCD, Plasma and OLED, and even combinations of them, such as TFT LCD, and many more without knowing they differ from each other. Mashable does not necessarily agree. With this guide, we hope to explain the advantages and disadvantages of these technologies, and to clarify concepts. Mashable gathered all the information. TFT: First we should clarify that it is a TFT display technology itself, but it is simply a special type of transistor to be able to improve the quality of the image. Its most common use with LCD screens, as explained below. LCD and TFT LCD technology uses LCD liquid crystal molecules positioned between the polarizing layers and rotate as you want to display one color or another.

Its main advantage, besides its small size, is the saving of energy. When these TFT displays use transistors then we are talking about TFT LCDs, which are the most widespread today. PLASMA: Unlike LCDs, plasma displays use phosphors excited noble gases to display pixels and provide them with color. Although invented in 1964 it comes to technology but lagging in terms of level of implementation, the three we’ve mentioned because its price is higher (though increasingly the difference is less) and yet their quality is much better. Specifically provides greater viewing angle LCD screen, better contrast and realism between the colors displayed.

OLED: Finally, this technology also has a few years and we will also gradually seeing more constantly. This is a variant of the classic LED, but where the emission layer has an organic component. Surely you have heard that OLED displays have the advantage of requiring no backlight, thus saving much more energy than any alternative. In addition, its cost is also lower. However, the time allowed is not as good as older technologies that we have discussed.
