The type of display used by any smartphone determines how excellent the gadget is. iPhones Xs and Xs Max are among the iconic Apple’s 2nd generation flagship phones and they employ exceptional OLED displays. However, although the two gadgets use OLED display, the iPhone Xs Max has the edge over its earlier Xs counterpart, courtesy of the latest improvements.
What Type of Display Does iPhone Xs and iPhone Xs Max Use?
Apple’s latest flagship iPhones, the iPhone XS and iPhone XS Max were unveiled on September 12, 2018, but have been superseded by newer versions. When Apple launched the new iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max smartphones on September 10, 2019, the two iPhones faced discontinuation. However, some resellers may still have the XS and XS Max for sale at discounted rates.
Both iPhones have the same design as the iPhone X, but there is now a bigger 6.5-inch variant and the 5.8-inch one. With support for Dolby Vision, HDR 10, and Wide Color, the iPhone XS and iPhone XS Max have the sharpest OLED screens and the most excellent pixel density of any Apple product.
The iPhone Xs and iPhone Xs Max keep up with the all-screen design of the iPhone X, with the most precise screens and maximum pixel density of any Apple product. These Super Retina screens with a bespoke OLED design are now available in 5.8-inch and 6.5-inch sizes1 and support Dolby Vision and HDR10 and iOS system-wide color management for the highest color accuracy in the industry.�?
The iPhone Xs and iPhone Xs Max have a million-to-one contrast ratio, which means they have incredible brightness and accurate blacks and a 60 percent wider dynamic range in HDR photographs.�?
With over 3 million pixels for films, movies, and games, the iPhone Xs Max provides a more immersive experience, with the most prominent display ever in an iPhone in a footprint similar to the iPhone 8 Plus.
The iPhone XS Max sports a more prominent 6.5-inch full-screen display that spans nearly the whole front face of the phone. The iPhone XS Max’s Full-Screen design results in a 21% greater Display Screen Area than the iPhone 8 Plus, even though both phones have the exact overall dimensions.
Because the screen now has the same overall shape as the phone, it has a new form aspect with a more considerable height to width Aspect Ratio of 19.5: 9 = 2.17, which is 22 percent larger than the 16: 9 = 1.78 on most Smartphones (and widescreen TVs). Portrait mode is taller, while in Landscape mode, it is broader.
That gives you more room for Notifications and for showing numerous Apps and material on the screen simultaneously.
The front-facing camera, ambient light and proximity sensors, the ear speaker, and other sensor systems are all housed in a black 0.2″ high (5 mm) Slot cutout area from the display at the very top of the screen.�?
Because it just takes up 1.7 percent of the entire Screen Area, it’s noticeable yet simple to get used to. We commonly use the left and right tabs on each side of the Slot to display App data that it would otherwise display in the main display area.
What is an OLED Display, and How Does it Work?
You’ve undoubtedly heard the word “LED” before, even if you’re not a display specialist. It stands for light-emitting diode, a broad phrase that may refer to everything from the lights that power your TV to the little charge indicator that flashes when you put in some devices.�?
OLED is a member of the same technology family as LCD, but the additional letter makes a significant distinction.
Organic light-emitting diodes have a similar function to ordinary LEDs; however, they work differently. Traditional LEDs emit light using silicon, but OLEDs use organic material. According to OLED-Info, what emerges as a thin layer sandwiched between two conductors.
To truly comprehend how this works, you’ll need a lot of scientific expertise, and it becomes much more complicated when you include AMOLED or active-matrix organic light-emitting diode. AMOLED technology is in a wide range of products, from smartphones like the Samsung Galaxy Note 20 to televisions.
AMOLED is a technique for displaying images on an OLED panel. In contrast to PMOLED, or passive matrix OLED, which isn’t often utilized for smartphone screens, each pixel has its transistors and capacitor.�?
In other words, the active version provides for more precise pixel control than the passive version, which controls pixels by rows and columns and isn’t as common in consumer electronics.
What precisely is an LCD?
In general, there are two types of iPhone screens. Other than OLED, there is LCD which stands for liquid-crystal display. Let’s look at two of the elements that make LCDs operate to simplify the discussion (and this is a huge simplification). The first is their pixels, which determine the colors seen onscreen.�?
Each pixel has three subpixels that alter in intensity: one red, one green, and one blue. When you navigate through Instagram, watch a YouTube video, or look at your photographs, that blend of colors forms the visuals you see.
The backlight is the LCD’s second component. The backlight is a panel that lies behind the pixels and beams light through them so you can see what you’re looking at.�?
When you modify the brightness of your display, you’re managing the backlight, which covers the entire display; think of it like a lightbulb; you can’t make one portion of it brighter while the other goes dimmer.
How is OLED Different from LCD?
LCD, or liquid crystal displays, are being phased out in favor of OLED. Given how pervasive LCD technology has become since its beginnings in the early 1960s, you may be reading this article on one right now!�?
For comparison, all iPhones before the iPhone X had LCDs. The standard iPhone 11 uses LCD, with the more costly iPhone 11 pro switching to OLED.
The existence of a backlight is an essential functional distinction between OLED and LCD that you should be aware of. The previously discussed organic film emits light when an electrical current passes through an OLED display. To put it another way, OLED can work without a backlight.
Why is OLED Good for the iPhone Xs and Xs Max?
Here’s an example of why this is fantastic: Let’s assume you’re on your phone watching a movie. Whenever dark sequences are in the film, those parts of your display will switch off. A night sky turns black; if the movie is widescreen or 4:3, the top and bottom bars and the left and right bars go entirely dark. It produces a pleasing image, especially if you watch in a dim-lit environment.
These are the reasons why OLED TVs are spectacular. The image is excellent, and letterboxing bars vanish when viewed in absolute darkness; you only see the section of the screen that you should see (whether it be super widescreen or the old square format).
When it comes to iPhones, you can easily see the difference between an LCD and an OLED iPhone by filling each panel with a black rectangle. The OLED iPhone would appear switched off, whereas the LCD iPhone would appear black but with a lit display.
The ability of OLED pixels to turn themselves off has significant consequences for battery life. You may save battery life on your iPhone by utilizing dark mode, especially dark mode with black backgrounds. (Grey elements won’t turn the pixels off, so you’ll need all-black elements to keep your iPhone’s battery from needing to power every pixel).
Color Accuracy Is Extremely High. Because everything on display has to be precisely ideal, delivering brilliant color with high Absolute Color Accuracy is quite challenging. A display must roughly match the Standard Color Gamut used to create the information to produce realistic visual colors – not more, not less. In addition, it requires an exact (pure logarithmic power-law) Intensity Scale and an accurate White Point for the display.
iPhone XS and XS Max Color Management
Because the iPhone XS and XS Max support two Standard Color Gamuts, Color Management must ensure that the smaller sRGB / Rec.709 Gamut produced from the larger native DCI-P3 Gamut appears accurately.
Color and Contrast Accuracy get independently calibrated in each iPhone XS, and XS Max display at the manufacturing process.

What are the Drawbacks of OLED Technology?
Burn-in has always been the biggest problem with OLED screens. Unfortunately, you’ll notice this a lot with OLED TVs; after a long usage period, the “shadow” of static pictures will appear on your screen. People who watch a lot of news, for example, complain that the chyron, news ticker, and outlet logo are constantly visible on their televisions.
However, Apple has done an excellent job of preventing burn-in on OLED iPhones, and it isn’t a widespread issue. The first OLED iPhone, the X, has been on the market since 2017, and there have been no reports of lingering images in that time. To put it another way, if you’re worried about burn-in, you don’t have to go out of your way to get an LCD iPhone.
