For most users, the technology that powers a smartphone is usually not extremely interesting, as long as it provides a good experience for anyone using it. This applies to most modern smartphone screens, and many would be surprised to learn just how many different types of displays there are, and how different the technology is for each kind. These are some of the most popular in production at the moment.
Active Matrix Organic Light Emitting Diode, or AMOLED for short, is one of the most common types of screens in the world, and can usually be found on most of today’s Samsung devices. While the name makes it seem like the most complicated technology in the world, the fundamentals behind it is nothing new, but rather an evolution of previous technology that we’ve been using for decades. OLED is a material that emits light whenever electricity passes through it, meaning that it’s able to display light and colour on its own. This is different from LCD displays, which use a backlit LED to light up the crystals. OLED displays are always off, meaning that they turn off completely when there’s no light. This provides much more prominent darker colours and blacks on the screen, and also uses less battery, although it can lead to burn in if left on for too long, but this tends to be rare.
The other main type of display on the market is liquid crystal display, a technology that has been around for decades, and was once the standard for most smartphones, monitors, and flat screen televisions. LCD is still very much popular at the moment, although we’re starting to see more and more people moving away from LCD in favour of organic LED. Work is currently being done on quantum dot LCD technology, which is meant to provide much higher resolutions in the future. LCD tends to be cheaper than AMOLED, but because of the way that light is produced behind the screen, the background whites tend to lose their starkness, which is much more visible on the edge of the screen.
Retina is the proprietary display exclusive to Apple products and has been around since the release of the 4th generation of iPhones. Apple defines its screens as having resolutions high enough that they are not discernible by the human eye, which provides them better viewing distances and makes them perfect for playing at https://slotscanada.net/. Despite the claims, it’s important to remember that Apple’s displays are made from the same technologies as other industry standards, and many of the benefits of the screens are marketing displays. There’s no denying, however, that Apple has some of the best screens on the market, providing extremely high pixel density per square inch.
The refresh rate of a touchscreen refers to the amount of times that the screen is able to refresh itself within a single second. At the moment, there are three main standards: 60hz, 90hz, and 120hz. Most of today’s phones offer 60hz displays, which is perfect for most users, although it’s not uncommon for flagship phones to offer up to 120hz.
