There are a variety of television types that one can choose from with each offering its own advantages.

Televisions differ according to the type of display technology used. For example, a Liquid Crystal Display (LCD) can come with either flat panel or rear projection displays. LCD televisions do not burn in images like plasma TVs, but they can have ghost effects due to slow FPS speed. They are also susceptible to a type of pattern known as the screen door effect when projection is used.

Plasma display panel televisions (PDP) activate gases like xenon and neon to create images between two plates of glass. The picture quality of PDPs is unmatched and they are priced in much the same range as LCD flat panel televisions. The plasma television is vulnerable to the burn-in effect due to the uneven effect of phosphors on the screen. Burn-in can be controlled by reducing contrast, enabling pixel shifting, and by taking other precautionary measures.

Digital Light Processing (DLP) televisions use micro-mirrors to create digital displays. This technology was invented by Texas Instruments in 1987. Although they are not susceptible to burn-in, they do have a problem known as the Rainbow Effect that appears as a type of flashing of different colours. The Rainbow Effect is caused by colour wheel spinning. LED and Laser DLPs that do not use a colour wheel have eliminated the Rainbow Effect.

Tube televisions that use a cathode ray tube represent the original type of technology used for television viewing. The CRT is good for viewing from all angles unlike flat panels, which often must be viewed at a more direct angle for good images. CRTs also have the best black levels and are economically priced. However, CRTs take up a lot of space and are heavy. They brightness and radiation of the CRT display can also be hard on the eyes.

High definition television
Televisions can also be distinguished by the definition of the images. Although there was some development of analog high definition TV (HDTV), this was abandoned to pursue digital HDTV instead. Improvements in digital compression lessened the bandwidth needs of digital broadcasts making HDTV available to wider audiences. HDTV is more expensive but it allows for very high quality viewing including home theatre projection.

Analog vs. Digital TV
Some televisions handle only analog or digital broadcasts, but increasingly most now can accept both types of broadcasts.
