the i stands for interlaced. Interlaced means the TV draws all the odd lines then all the even then interlaces them to trick you eye into seeing the full picture. The p stands for progressive meaning it progressively draws all 1080 lines of resolution, (not 540 odd then 540 even like interlaced) so you get a true 1080 picture not a 540 doubled.

1080p is the shorthand name for a category of display resolutions. The number "1080" represents 1,080 lines of vertical resolution, while the letter p stands for "progressive scan" (meaning the image is not interlaced). 1080p is considered an HDTV video mode. The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels. This creates a frame resolution of 1920×1080, or 2,073,600 pixels in total. The frame rate in Hertz can be either implied by the context or specified after the letter p, such as 1080p30, meaning 30 Hz.
1080i is a shorthand name for a category of video modes. The number 1080 stands for 1080 lines of vertical resolution, while the letter i stands for interlaced or non-progressive scan. 1080i is considered to be a high-definition television (HDTV) video mode. The term usually assumes a widescreen aspect ratio of 16:9, implying a horizontal resolution of 1920 pixels and a frame resolution of 1920 × 1080 or about 2.07 million pixels.
Progressive or noninterlaced scanning is any method for displaying, storing or transmitting moving images in which all the lines of each frame are drawn in sequence. This is in contrast to the interlacing used in traditional television systems where only the odd lines, then the even lines of each frame are drawn alternatively (each image now called a field) are drawn.

Look at a standard def TV. Look close and you will see faint horizontal lines in the video image.
This is an interlaced device. The lines are caused by fade between the time the odd lines are drawn and the beam goes back to draw the even lines.
Look at your computer monitor. No horizontal lines. This is a progressive device. It looks sharper and smoother because the screen is painted in 1 progressive pass, not odd/even passes.

The i is an interlaced frame. The frames are shown in numerical order, odd then even at a specific frame rate. The p is a progressive frame. Both odd and even frames are shown at the same time at a specific frame rate. Both i&p equal 60 frames per second, but with both frames being shown at the same time in progressive mode the eye registers a smoother and better looking picture. That is the simplest way I can describe it without going geek on you.

i stands for interlacing, the p stands for progressive scan. You can read up on the differences here: http://en.wikipedia.org/wiki/1080i
scroll down to the section that compares the 2. Happy hunting!

i for interlaced. P for Progressive. Progressive it is better then interlaced.
