On September 13, Apple's autumn conference launched three new iPhones, and the iPhone XR may be the most interesting. Compared to the more expensive iPhone XS and XS Max, XR is very similar.

The difference between the iPhone XS OLED and the iPhone XR LCD


Of course, except that it does not have a dual lens camera. But Google has already demonstrated the capabilities of a single-lens camera. If Apple's software improvements are as good as the company claims, then XR will not be inferior in photography.


Other than that, there are not many obvious differences. All three devices use the same A12 Bionic processor. Both support Face ID and wireless charging. Compared to IP68 in XS and XS Max, XR has an IP67 rating.


However, the most important difference is the display. Not the size of the display: the XS is 5.8 inches, the XS Max is 6.5 inches, and the XR is 6.1 inches. It is the type of display. That is the iPhone XS OLED screen and the iPhone XR LCD screen. Iphone XS and XS Max models start at $350 and $490, respectively, and this is a big revenue for OLED panels.


So, is this price worth it? Let's take a look at the following.


Surface difference


Let's first take a look at their actual statistics. The XS model display can reach 458PPI per inch of pixels. The XR model display can reach 326PPI per inch of pixels. In other words, the XS device has a higher resolution display.


It is worth noting that the OLED or LCD does not affect the resolution of the display. In any case, higher resolution means higher image quality. However, more pixels means more power is being consumed.


The XS model also features 3D Touch. Similarly, regardless of the type of display, the iphone 7 and iphone 8 models are equipped with an LCD display. However, XR uses the Haptic Touch technology, a long-touch feature of "tactile touch" that borrows the tactile feedback of the MacBook trackpad.


Finally, the XS model has a higher contrast. Apple's official website lists two XS devices with a contrast ratio of 1,000,000:1 and an XR device with 1,400:1. This is the difference between OLED and LCD.


Why is OLED with higher contrast?


It all comes down to how the display works. A liquid crystal display (LCD) has a constant backlight. A panel of the same size as the display produces a steady white light that illuminates the display. The amount of light that is illuminated can be controlled by a polarizer and filter in front of the backlight.


In addition, they also form the image you see on the screen.


But no matter what, the LCD display is not bad. It has been the preferred flat panel display technology for some time. But it has some drawbacks in terms of mobile devices - mostly related to backlighting. Organic light-emitting diodes (OLEDs) do not use backlight technology. Each pixel will glow by itself. It is also possible to control the luminance of the light through each pixel. This means that the white is brighter and the black is darker. The displayed image has a stronger contrast and is more vivid.

This difference can be seen in the image above. From the iPhone 7 Plus equipped with an LCD panel on the left side of the figure and the iPhone X equipped with an OLED panel on the right side, you can clearly see the difference in contrast.
