For many years your biggest consideration when buying a television was what size screen to select. This was usually dictated by your budget and the space you had. Once those variables were determined the project was simple. Buying a TV in the current market is a much more complicated task: there are LCDs, Plasmas, and projectors to choose from. Before a purchase can be made, first one must understand what these options are and how they compare against each other.
LCD TVs and Plasmas function differently to achieve the same desired effect: providing a sharp, clear, highly responsive image. LCD televisions have crystal cells that tighten and unwind accordingly as they are sparked by an electronic impulse. A bright backlight suffuses the cells and as they rotate they filter out every color in the spectrum except for the required one. Plasma TVs have thousands upon thousands of pixels that, when activated, release gases that work to produce a specific color in the red, blue and green bands contained within the pixels.
Until recently Plasma televisions were significantly superior from a number of perspectives. Because of the winding and unwinding motion of the cells in LCD televisions, fast moving video, especially sports and action movies, often displayed a trailing effect as the images changed and shifted. Plasmas do not exhibit this because each of their pixels is activated individually. Plasmas produce undistorted images at sharply-angled viewpoints, unlike LCDs, whose images could appear somewhat corrupted when viewed at similar angles. Plasmas also revealed much deeper colors than LCDs, with especially TCL Smart TV strong blacks.
Upgrades and improvements in the LCD format have enabled it to match Plasmas in areas that it had shown deficiencies. LCD TVs also have many clear advantages over Plasmas. Plasmas may have at first been able to boast the largest screens, but they by no means have the smallest. LCDs now have screen sizes that can nearly match the largest plasmas, and they can be made so small that they equip many phones. They are also much more portable. Plasmas are very heavy and often thicker televisions, which makes it difficult to transport them. They also cannot be mounted to weaker ceilings or walls because of their weight.
Plasmas do have their own pitfalls. Because they contain gases, they are affected by air pressure. This means that they do not perform as well at high altitudes. LCDs, however, are not affected by this. Consequently, they are used in most airlines and are preferred in many high cities. Plasmas also experience a burn-in effect, which occurs when a still image is left on the screen for a long period of time. This can occur when a movie or video game is left on pause for an extended duration, or if the screen is being used to t
