There are other categories such as 720i and 1080i that also belong to high definition, but none is Full-HD like 1080p.
When the first televisions came out, they worked through a cathode ray tube, known by its acronym in English CRT. These launched a ray from the back of the screen, which moved at high speed, passing through lines the monitor and painting it vertically. The number of lines painted represents the concept of resolution.
Hence the concept of progressive arises, which is the letter that has been seen previously accompanying the amount 1080. This type of resolution arises from the need to find a solution to the " flicker effect ", which caused dizziness problems in people who they watched the images on television and what it created was a division of images and the only way to solve it was through line spacing and progressive lines.
Currently the 1080p alphanumeric code has become the crucial number in the world of televisions. 1080p or Full-HD resolution has overtaken high-resolution HD.
