It is nothing like which one is better. Both 720p and 1080i have their own qualities. Though not quite visible but technically the displayed images on 1080i slightly flickers.
This causes a psychological difference, and some people like the slightly more ‘stable’ picture of 720p, while others prefer the whopping resolution of 1080i. If you find it difficult to decide, our only suggestion is that you run down to your local TV store and see for yourself.
After all, the beauty is in the eyes of the beholder.
Different TV display technologies
There are three different formats, which offer the HD technology.
CRT (Cathode Ray Tube) – This paints the images onto the screen. The style is perfect in any lighting condition and from every angle.
Plasma Display – It has an ultra-thin design, and it displays digital images at a high resolution. The major drawback is that it is costly and picture quality is affected, as it does not display black color efficiently.
Moreover, many plasma displays do not display HDTV resolution.
LCD (Liquid Crystal Display) – It uses two different polarized, transparent panel to house a liquid in the middle. It is thin in design but there are certain size limitations. Picture quality is good for static displays only.
When it comes to display images in motion, LCD does not perform well. Moreover, many LCD displays are not HDTV capable.
