Full HD is a term used to describe television display technology that is a standard for high-definition television in terms of video quality and sharpness. It is defined as an image with a resolution of 1920 by 1080 pixels. Blu-ray discs are capable of producing a 1080 progressive signal, and since 2012 most smartphone screens have been made to display a full HD image/video signal.
Full HD is also known as 1080 progressive or 1080p.
Full HD provides 1080 lines of resolution with progressive scanning. In contrast to other conventional methods of displaying images and videos, full HD offers interlaced scanning, where each scan displays alternate lines in the image raster, and two complete scans are therefore required to display the entire image. The full HD standard was introduced after the use of digital television for home and offices became common. In the widescreen aspect ratio, full HD is 16:9, which translates into 1920 by 1080. Modern-day camcorders, smartphone cameras and many other devices can capture 1080p video and encode it in progressive segment frame format.
