A 10×10-pixel image printed in a 1-inch sqaure has a resolution of 10- pixels per inch. The first phone to launch with a 1080 screen was- HTC j Butterfly
What is the difference 1080 or 1080i?
1080 refers to a screen which is 1080 pixels wide, with lines run the entire vertical length of the screen
However, 1080i is different, which is 1080-interlaced where the p in 1080 stands for progressive scanning, 1080 has much smother transitions than 1090i and it is therefore more common in standard home television sets.
What are the different resolutions?
The latest mobile phones and LED TVs the display is not square BUT A REACTANGLE therefore you mostly see companies mentioning the resolution like this

- 1080 = 1920 x 1080 – is usually known as FHD or Full HD Ready resolution
- 2K = 2048 x 1080 – this refers to displays that have a horizontal of 2000 pixels
- 1440 = 2556×1440 – known as Quad HD resolution, it is four times the resolution of 720p HD
- 4K or 2160p = 3840 x 2160 – known as 4k, UHD or Ultra HD resolution 2160p is called 4K because the width is close to 4000 pixels
- 8k or 4320 = 7680 x 4320 – known as 8k and it refers 16 times more pixels than the regular 1080p FHD or Full HD resolution
What is the human vision limit?
Real human vision limits are actually much higher than the possibly closer to 900 PPI or more Research from sharp think that human can see up to 1000 PPI.
