Pixel: What is it and Why Should You Care?

You may have seen the term pixel on your phone or computer screen and wondered, What does that mean? A pixel (short for picture element) is a tiny dot that makes up the image you see on your device when you open an app, browse online, or watch TV. In this blog post, we explain what pixels are and why they matter. We’ll also tell you what to look out for so you know when it’s time to replace your phone or computer.

Pixel: What Is It?

The first thing to understand about pixel density is that pixels are everywhere. Pixels power all of your digital interactions, whether you realize it or not. A single pixel on a mobile device's screen may be a lot smaller than one on your computer monitor, but they are each just as important. What Makes Phone Pixel So Special?: There are two types of pixels (and two terms for them): dots and pixels. Dots refer to physical components in an LCD panel; pixels define how much light comes out of those components when charged. That’s why OLED screens tend to get better ratings than LCD screens; OLEDs have a higher resolution because their individual lights can be turned off individually.

Pixel Density

Many mobile phone users are not aware of pixel density. The pixel density simply refers to a pixel’s ability to make an image appear sharp. A higher pixel density can better display an image that has finer details, resulting in better quality. However, there are several factors that affect a picture’s overall sharpness. For example, when an image’s size or resolution decreases, or when there is too much ambient light or glare. In addition, how you hold your phone may also have a major impact on what you see on screen. Pixel density has many benefits for both phone owners and companies alike, but if you’re in doubt about its importance – remember that your eyes can tell you everything they need to know.

Phone Pixels vs Computer Pixels

When we say pixel, there are two things that come to mind—computer pixels, which is a unit of measurement for screen size, and phone pixels, which measure screen resolution. Pixel density determines how many pixels you have on your screen. So if you have a 13-inch laptop with 1920x1080 resolution (aka 1080p), then you have 227 pixels per inch (PPI). So when we look at phone displays, they’re usually measured in megapixels—that’s right, regular photo camera megapixels. The image above shows that there are only 400 pixels per inch on an iPhone 6s display compared to Samsung Galaxy Note 5's 518 PPI.

How Many Pixels Do I Need?

First, let’s start with what pixels are. Pixels are small points of color on your phone display that make up an image or a photograph. The more pixels there are, the more detailed and clear an image will be when displayed on your screen. Ideally, you want to buy a phone with at least a 1080p HD display (1920 x 1080). It will give you a crisp picture without having to zoom in too close. But even phones that offer 2K displays (2560 x 1440) will look great when held from a normal distance away from your face.

Other Characteristics of a Good Screen

Brightness. Your phone’s screen can’t be too bright or too dim. Some screens are just too bright, which will hurt your eyes after a while. Others may not show off what you’re doing on your phone very well, which can make using certain apps frustrating, or even impossible at times. Make sure that your screen’s brightness is not so high that you have to squint, nor so low that you have trouble seeing anything but light and dark spots on your screen; somewhere in between will ensure that you can use your smartphone effectively while also making sure your eyes don’t get damaged by looking at a bright screen for long periods of time.

Color Gamut and PPI

In order to improve readability on digital devices, phone pixel manufacturers are now designing their displays to display more colors. This improves accuracy in photo reproduction, but it also means that a single pixel in your phone can represent a smaller point of color than ever before. That’s why an HD screen with a higher PPI count may appear sharper than one with a lower PPI count – even though both screens will probably be capable of displaying 1080p resolution or better. How many pixels do you need for accurate image reproduction? It varies depending on what type of content you’re viewing and what kind of device you’re using, but generally speaking, higher resolutions aren’t necessarily better unless they result in less blurring or jagged edges.
