Progressive means a full frame scan, so something that is 25p means there are 25 full frame scans per second. Interlaced however breaks the frame into thin lines (or fields). It then alternates between scanning odd and even lines. So something that is 50i means that 25 times a second it scans the even lines and 25 times a second it scans odd lines.

Interlaced and non-interlaced are terms describing how a single frame (or picture) of television is put on the screen. In both cases the frame is composed of a number of horizontal lines which together make up a page. The "obvious " way to do this is to paint the lines in order : 1, 2, 3, 4, . . . .623, 624, 625. Unfortunately this leads to a visible flicker effect on the screen. A way to reduce the flicker effect is to paint the screen in two parts : 1, 3, 5, . . . 621, 623, 625, 2, 4, 6, . . . 620, 622, 624. The result of this is to interlace two halves of the image. It's not really a brand new technical term - people have been interlacing the fingers of their hands and using the word to describe it for hundreds of years. Some TV systems, especially low cost security systems, use the "obvious" method. This is called non-interlaced.

Interlaced images are created by drawing alternate lines of an image from the top of the image to the bottom. The lines are all odd numbered. When they are complete, the even numbered lines are drawn in the gaps left by the first pass. In two passes, a complete image is generated.

All standard definition video and some HD video is delivered in this way with the formats of 480i, 576i and 1080i being the most commonly known.

Progressive scanning generates the image in a similar way but draws consecutive lines to build a complete picture in a single pass. Video formats that work this way are 720p and 1080p

The interlaced scanning was introduced many years back when limitations on data transmission rates meant that interlacing offered a smoother looking image than progressive scans.

Television images are created from many lines that build into a complete picture. HD signals use 720 or 1080 lines for example. The image is refreshed at intervals to create moving images.

Interlaced signals use two passes of the image to build a frame. The first pass updates all the odd numbered lines, 1, 3, 5 through 1077, 1079. The second pass updates the even numbered lines to complete the full picture. The process repeats 25 or 30 times each second.

Progressive signals update the frame in a single pass, refreshing every line 1, 2, 3, 4, to 1079,1080.

The letter "i" or "p" after the line number indicates whether the signal is interlaced or progressive.

Which provides better quality an interlaced monitor or noninterlaced monitor?

Interlaced, not interface. Interlaced scans every second line. Progressive does not.


What is the difference between interlaced and non-interlaced monitors?

# Interlaced versus non-interlaced. Which is better...Simply put, non-interlaced monitors (or rather, non-interlaced video modes) are considered superior because they tend to produce less flicker.# Why do interlaced monitors tend to produce more flicker...The reason is non-interlaced monitors/video modes use only one pass or "sweep" of the electron gun, whereas interlaced monitors/modes use two passes or "sweeps" to display the same image. With interlaced monitors/modes, one set of lines is made on the first sweep then, a split second later, a second sweep creates more lines to fill in areas left open after the first sweep. More accurate results can be had when one sweep, rather than two sweeps, produces the image. Non-interlaced monitors are capable of interlacing, but the display results are better with non-interlacing; thus, there is no sense or desirability to use interlaced modes on non-interlaced monitors.
