What is an LCD or Plasma TV?

 

CRT or TFT what is the difference?

CRT technology or Cathode Ray Technology has been around for decades the earliest version of the CRT was invented by the German physicist Ferdinand Braun in 1897 From mono though to Colour.
CRTs, despite recent advances, have remained relatively heavy and bulky and take up a lot of space in comparison to other display technologies.

CRT screens have much deeper cabinets compared to flat panels and rear-projection displays for a given screen size, and so it becomes impractical to have CRTs larger than 40 inches (102 cm).

The CRT disadvantages became especially significant in light of rapid technological advancements in LCD and plasma flat-panels which allow them to easily surpass 40 inches (102 cm) as well as being thin and wall-mountable, two key features that were increasingly being demanded by consumers.

Additional issues that CRT’s suffer are Large size and weight, especially for bigger screens (a 20-inch unit weighs about 23 kg), High power consumption, Generates a considerable amount of heat when running, Geometric distortion caused by variable beam travel distances and can also suffer screen burn-in when left on pause for long periods of time.

TFT or Thin film transistor liquid crystal display (TFT-LCD) is a variant of liquid crystal display (LCD) which uses thin-film transistor (TFT) technology to improve image quality

TFT screens were previously limited to the wealthy and of course were an essential part to a Laptop or Notebook due to size weight compared to CRT’s

1972: The first active matrix liquid crystal display panel was produced in the United States

Liquid-crystal display televisions (LCD TV) are television sets that use LCD technology to produce images. LCD televisions are thinner and lighter than CRTs of similar display size, and are available in much larger sizes.

In 2007, LCD televisions surpassed sales of CRT-based televisions worldwide for the first time, and their sales figures relative to other technologies are accelerating.

LCD TVs are quickly displacing the only major competitors in the large-screen market, the plasma display panel and rear-projection television.

LCDs are, by far, the most widely produced and sold television display type.
