Today's thin, digital, wide-screen high-definition TV (HDTV). Most flat panel TVs are self-contained with a tuner and speakers that can receive over-the-air broadcasts. A few models are only display screens that require content from a set-top box.
LCD and OLED
LCD and OLED are the primary technologies. LED TVs are actually LCD TVs with an LED backlight. See LED TV
The common HDTV is 1080p (1,080 progressive scan lines); however, earlier, smaller sets were 720p. Although Blu-ray supports 1080p, TV and cable channels broadcast in the lower 720p and 1080i resolutions. It is difficult to tell the difference on smaller sets. 4K TVs with 2160p resolution have become the norm, and 8K TVs have emerged. See DTV

Fond of Vintage Content?
If you watch standard definition (SD) content such as DVDs and VHS tapes, all HDTVs are not the same. The TV upconverts SD content to the higher resolution, and some sets do a better job than others.
Size Makes a Difference
Whether SD or HD, an enormous amount of complex processing takes place, and the larger the screen, the more pixelation and other visual artifacts are noticeable. It takes a high-quality 65" TV to look as good as a low-end 32" set, and even more so with an 80" TV (see 4K TV

Although all flat panel TVs can be wall mounted, models 40" and above require a strong support. The wall bracket must be bolted into the studs of sheetrock and plaster walls by an experienced installer. See HDTV display modes
