If the picture quality of your TV is your primary concern, you're looking at evaluating a number of factors before making a decision. Although CRTs offered pretty great image quality, they've now been superseded by flat screen TVs which hold several advantages over them. However, if you've got the option of an HD CRT TV, and don't mind the awkward size and lack of added features, take it! They give you excellent picture at just a percentage of a flat panel TV's cost.
Flat screen television today is largely dominated by LED TVs and Plasma TVs and in this article we've excluded LCD sets as they're not really in the competition for the best picture. LED TVs use a panel of Light Emitting Diodes as a light source for their LCD screens, as opposed to LCD TVs (or CCFL LCD TVs) which make use of Cold Cathode Fluorescent Lamps. This makes LED TVs superior in terms of contrast, viewing angles, lifespan and power efficiency; and this is the reason behind that mysterious price hike. Depending on where the LEDs are placed, LED TVs can be of two kinds: Direct/Full array-lit or Edge-lit, which you can find out all about in our guide to the best LED HDTVs
To transcend the limitations of a conventional LCD's display quality, manufacturers implement the underlying concept of local dimming under varying epithets and altered technologies to boost the contrast ratios of their TVs. Local Dimming is the mechanism of controlling groups of LEDs to dim them or turn them off when a scene demands deep blacks for high contrast, to display richer image detail.
The key to a plasma TVs high contrast ratios is the absence of these LEDs or CCFLs as a backlight. Plasma TVs obviate the need for any backlighting since the plasma itself is light source and the pixels here are individually controlled, so you can have a pixel which emits light next to a black one. So you see what this means? If each pixel is independent of the other you can have perfectly accurate image depiction and even richer details than in an LED! However, even the best Plasma TVs have one drawback in terms of display quality. They come with glass screens and do not have a very high brightness output, so in well lit rooms plasma TVs might suffer loss of picture quality and a lot of glare.
For the best display quality in sports scenes and games, the decisive factor is the response time of the TV, or simply put, your TVs ability to change from one image frame to the next. This is mainly an issue with LED TVs because the pixels in the LCD screen takes time to go from one value to the next, but the best LED TVs today boast a rapid response time of 5 ms to 2 ms which is quick enough to give free flowing picture. The best Plasma TVs on the other hand have what's known as 600 subfield drive to display 600 frames per second precluding any motion blur in action packed videos. In terms of viewing angles, the best plasma TVs outrun even leading LED TVs which offer a 178 degree viewable angle.
Furthermore, we've heard customers hunt for TVs with the best contrast ratios for great display. However, we've like to point out that contrast ratios are not a recommendable criteria to base your search on since this ratio as yet has not been standardized to a specific unit, and manufacturers use various methods for their measurement that can't be comparable to each other. You'll need to watch the quality with your own eyes to perceive the difference. So if weighing the contrast of your television is important to you, quit hunting online and visit your nearest store. Our list below has the top rated flat screen TV s for display, along with their individual ranking, from television giants like Panasonic, Vizio, Samsung and LG.
