480i / 480p / 720p / 1080i / 1080p
Generally refers to the number of effective scanning lines that determines the screen's resolution.
There are two scanning methods: interlaced and progressive.
–
Scanning
Sequential projection of pixels to form images. The higher the number of pixels, the clearer
and more vivid the images.
–
Progressive
A sequential scanning method that scans every line, one after another.
–
Interlaced
A staggered scanning method that scans every other line until the end of the screen and then
fills in the remaining lines.
Example) If the number of horizontal scan lines is 480i
Scans 240 lines from start to finish and then scans the remaining 240 lines for a total of 480
lines.
