The new iPhone X R X S and X S Max has all buzzed. But at first glance, the X R and XS look very similar in almost every way. So, what's the difference? It comes down to the "Liquid Retina" LCD screen of the XR against the "Super Retina" OLED display of the XS. How do they compare and why does it matter which new iPhone is pre-ordered?
This discussion is nothing new – the now discontinued iPhone X was the first of Apple to show an OLED display, while the iPhone 8 and 8 also came with the standard LCD that we got used to. All the points below can also be applied to these iPhones, except for the missing Touch ID.
OLED vs. LCD
OLED technology has increasingly found its way into consumer tech products in recent years. If you were about to go to Best Buy, there is a good chance that any smartphone or TV you pick up will have an OLED display. But what is it and is it better than LCD?
To keep it simple, when your display is OLED, each pixel on the screen emits its own light. This means that black areas of the screen do not need to be turned on at all, which both saves power and simply can not match the contrast of other displays.
LCD, on the other hand, requires a general backlight, so even if you fill the screen with a black square, you will still see light from the phone.
The big drawback of OLED displays, however, is their sensitivity to burn-in or afterimages when taking pictures once on the screen, are now visible when using the device. This often occurs with menus and other items that appear on the screen for a long time, but so far this has not been a common problem for iPhones.
