The Ultimate Guide To iPhone Resolutions

How can an iphone screen’s quality be determined?

In the digital world today, we discover a lot of devices in our day-to-day activities. We have various IoT devices, improved smartphones, and watches, etc. We communicate with these devices via a screen. Also, these screens are higher concerning not only the sizes but also their resolution and pixel density. A screen’s quality is defined by how sharp it is. Any visual display has a rectangular array of pixels. Programmers used pixels to size and position graphical objects. But as various screen sizes and pixel densities emerge, the idea of working with pixel became undesirable for programmers.

The phone’s visual object can be smaller than the individual item on a laptop, as the screen resolution and physical dimension of the phone are much smaller than laptop displays. 640 x 960 dimension of a 3.5-inch screen of the iPhone 4 is characterized by a pixel density of about 320DPI. 2 pixels are present to the point. Therefore, the screen appears to have a dimension of 320 x 480 to an application program running on this iPhone. iPhone 3 didn’t have a point equaled pixel and a pixel dimension of 320 x 480. Therefore, to a program running on these two devices, the display appears to be equal size, but texts and objects are displayed in a superior resolution on iPhone 4.

iPhone 6 is characterized by a 4.7-inch screen, with a pixel density of 320 DOI, having 2 pixels to the point, thereby appearing to have a point size of 375 x 667.

Furthermore, iPhones 6plus and 7plus both have a screen of 5.5 inches and a pixel dimension of 180 x 1920, which equates to a pixel density of 400 DPI. Note that the higher the pixel density, the higher the pixels to the point.

For iPhone 6plus, the point was set to equal 3 pixels. This would typically mean a thought screen size of 360 x 640 points. However, to a program, it has a point size of 414 x 736. Therefore, the thought resolution is around 150 points to the inch.
