The types of HDTV are categorized on the basis of technology, the screen width, and the requirement of either a HDTV tuner or an independent unit. While buying a HDTV, you have to consider these aspects carefully. Let us have a look at each of them separately.
Types of HDTVs Based On Technology
The most popular type is direct view HDTV that uses standard Cathode Ray Tube (CRT) and rear projection technology, similar to the standard TVs. However, this technology is going to get obsolete sooner or later. New advanced technologies are going to take over in the near future.
These technologies are cost-saving and loaded with extra features, such as, transmitting clearer and brighter images. The standard TVs stand no chance in competing with this new version, as they are burdened with the production costs and size restrictions.
The biggest direct view HDTV comes with a screen width of 36 inches. Besides this, the rear projection technology is shadowed with problems of screen burn in, convergence, and obscurity of image during brightness or at an angle.
The entertainment world has received a breakthrough with the introduction of amazing TV technologies like Plasma TVs, LCoS (Liquid Crystal on Silicon), LCD (liquid crystal displays), and DLP (Digital Light Processor) rear-projection units. Before a decade, one could have never imagined a television that could be hung on the wall! But Plasma TV has made this possible too.
Although each of these technologies displays their own advantages and disadvantages, they come with the promise of a better picture
quality. The HDTV’s installed with the advanced technologies are, in no case, inferior to the older versions of HDTV.
