Resolution

Resolution: A term that refers to the number or quantity of pixels on a someone smartphone display usually quoted as width × height, for example, 1280 × 720 suggests that the width is 1280 pixels and therefore the height is 720 pixels. If a smartphone has better resolution display suggests that additional pixels in smartphone and additional pixels offer the power to show a lot of visual info and resulting the display shows good clarity and lot of details in image or other visual.

If display has HD resolution, HD stands for high definition. HD simply means a pixel measurement of 1280 x 720 pixels

If display has Full HD resolution, Full HD stands for Full high definition that measures 1920 x 1080 pixels.

If display has QHD, Quad HD or 2K resolution, that type display stands for four time the standard HD,  that measures 2560 x 1440 pixels.

IF display has 4K or Ultra HD resolution, that type display stands for two time the 2K. The 4K measures 4096 x 2160 pixela and Ultra HD measures 3860 x 2160 pixels

Speaking about 2K, 4K, Ultra HD; 2K name comes from the pixel measurements is over 2000 pixels, 4096 pixels in 4K and 3840 pixels in Ultra HD

And another thing, Resolution doesn’t discuss with the physical size of the mobile display,  as an example, 2 displays with constant resolution will have completely different physical dimensions. And as for smaller there’ll be a lot of pixels per inch (PPI). In the smaller one, the image given by it ought to be clearer and a lot of elaborated.

The Pixels density (PPI) of smartphone display may vary according to screen sizes. For example- A smartphone at the 5-inch display, the pixel density sits around 440 ppi, while on a 5.5-inch screen that pixel density number drops to 400 ppi.
