BANGALORE: Smartphones are an integrated part in our daily life, from being just another device it became a vital companion. Nowadays everyone owns a Smartphone and are quite knowledgeable about their choice of purchase. Like the first features you look in a Smartphone may be numerous and depends, but at first glance on-hand one goes to enjoy the visual treat-display. If measurements are taken as to which amount of pixels if fitted in a display to make the picture appear real or play real-then there’s no exact answer, reports Androidpit.

As Steve Jobs believed 300ppi is the limit, in which a display should be designed as anything above will be overkill, as it will be no use fitting in more pixels if the human eye can’t conjure it. So here we discuss the new trends that made the process of rendering display to a fine digital version of reality.

The topic display is balanced on these pillars and they are display type, the diagonal measurement of the screen in inches and the definition or resolution. A display designed by a company goes under the process of first deciding the type of display it will be next the dimensions and then will be the important decision as to how many pixels needs to be crammed in it per square inch to concoct the display.

The diagonal measurement and resolution are the topics to be discussed, as to what the difference of pixel filling leads to name it as HD, full-HD, QHD or quad HD and 4K display.

HD

As we all know HD stands for High Definition, and the pixel measurement will be 1280X720 pixels. HD is also called as 720p, as at the end it gets shortened to 720pixels. No matter what the size of the display and how large the screen with a resolution of 1280X720pixels, it will still be called a HD display, no matter what. Most say the smaller the screen size more the pixels crammed in it and more will be the display. For ex a 4.3 inch and a 4.7 inch Smartphone with 342ppi and 312ppi are still said to have HD display.

Full-HD

The next in line saying Full-HD makes it has better resolution than HD, and so will be as the resolution of Full-HD is 192X1280 pixels. Though 2K technology is in full fervor still some manufacturers favor full-HD as after all the resolution depends on the screen size as to pixels spread diagonally. A 5-inch Full-HD display will have a pixel density of 441ppi.

Quad-HD

Also known as QHD or 2K, has four times the definition of standard HD and its resolution measurements are 2560X1440 pixels. The name 2K is because from zeroing the resolution it falls near 2000, so 2K. A 5.5 inch quad-HD display will have a pixel density of 538ppi.

Ultra-HD

Also known as 4K, the next in line, though it won’t be featured for Smartphones it will sure make an appearance for Phablets and Tabs. Though 4K and Ultra HD are said to be same they do have a small difference which needs to be spotted that is in the resolution. It is 3,860 x 2,160 pixels for Ultra-HD and 4,096 x 2,160 for 4K, and they are zeroed and frequently called as 2160p. 

So where does this journey of pixel placing end starting from HD, full-HD, QHD and Ultra HD, more technology which will beat this display resolution will be in future, but the question here is how they can fit the bill considering other factors that a Smartphone runs. Take the factor on which the Smartphone itself runs the battery the one that provide the power, with increasing resolution the processor has to work extra for which it requires extra power and ultimately the battery suffers to provide.

The manufacturers may have many ideas on paper and as to its implementation of bringing in a QHD or Full-HD display phone all the factors have to be considered and most importantly the price.
