Display Technology in iPhones, The iPhone has redefined smartphone design since its debut in 2007, and its display technology has been a cornerstone of that evolution. From the original 3.5-inch LCD to the latest OLED panels with ProMotion, Apple’s displays have consistently pushed boundaries. This blog post dives into the display tech across all iPhone models, tracing the journey from modest beginnings to cutting-edge screens that captivate tech enthusiasts. Let’s explore how Apple’s display choices have shaped the iPhone experience.
The Early Days: LCD Beginnings (2007–2012)
iPhone (2007) to iPhone 3GS (2009)
The first iPhone introduced a 3.5-inch LCD with a 320x480 resolution (163 PPI). Using a capacitive touchscreen, it was revolutionary for its time, offering vibrant colors and responsiveness that outshone resistive touchscreens. The iPhone 3G and 3GS retained this display, focusing on software improvements rather than screen upgrades.
iPhone 4 and 4S (2010–2011)
The iPhone 4 brought the Retina Display, a 3.5-inch LCD with a 960x640 resolution (326 PPI). This pixel density was a game-changer, making individual pixels nearly indistinguishable to the human eye. The IPS LCD panel improved viewing angles and color accuracy, setting a new standard for smartphones.
iPhone 5 and 5S/5C (2012–2013)
The iPhone 5 stretched the screen to 4 inches with a 1136x640 resolution, maintaining the 326 PPI Retina standard. The taller 16:9 aspect ratio enhanced media consumption. The 5S and 5C kept this display, with the 5S adding a slight color gamut improvement for better vibrancy.
Scaling Up: Larger Screens and Refinements (2014–2017)
iPhone 6 and 6 Plus (2014)
Apple embraced larger displays with the iPhone 6 (4.7-inch, 1334x750, 326 PPI) and 6 Plus (5.5-inch, 1920x1080, 401 PPI). Both used Retina HD IPS LCDs with improved contrast and dual-domain pixels for wider viewing angles. The 6 Plus’s higher PPI made it ideal for video and gaming.
iPhone 6S and 6S Plus (2015)
These models retained the same resolutions but introduced 3D Touch, a pressure-sensitive feature that added new interaction layers. Display quality saw minor tweaks, like better brightness (up to 500 nits), enhancing outdoor visibility.
iPhone 7 and 7 Plus (2016)
The iPhone 7 series kept the same screen sizes and resolutions but added a wide color gamut (DCI-P3), making colors pop with cinematic accuracy. Brightness increased to 625 nits, and the 7 Plus’s dual-camera system complemented its display for photography enthusiasts.
iPhone 8 and 8 Plus (2017)
The iPhone 8 series marked the last of Apple’s traditional LCD iPhones. They retained the 4.7-inch and 5.5-inch Retina HD displays but introduced True Tone, which adjusts white balance based on ambient light for a more natural viewing experience.
The OLED Era: Edge-to-Edge Displays (2017–Present)
iPhone X (2017)
The iPhone X was a turning point, introducing a 5.8-inch Super Retina OLED display (2436x1125, 458 PPI). OLED offered deeper blacks, higher contrast (1,000,000:1), and HDR support (HDR10 and Dolby Vision). The notch design and Face ID replaced the home button, maximizing screen real estate.
iPhone XS, XS Max, and XR (2018)
The XS (5.8-inch) and XS Max (6.5-inch) continued with Super Retina OLED, maintaining 458 PPI and HDR. The XR, a budget-friendly option, used a 6.1-inch Liquid Retina LCD (1792x828, 326 PPI), sacrificing contrast for cost but retaining True Tone and wide color.
iPhone 11, 11 Pro, and 11 Pro Max (2019)
The iPhone 11 kept the XR’s 6.1-inch Liquid Retina LCD. The 11 Pro (5.8-inch) and 11 Pro Max (6.5-inch) used Super Retina XDR OLED displays, boosting brightness to 800 nits (1200 nits for HDR). Improved contrast and efficiency made these screens ideal for professionals.
iPhone 12 Series (2020)
The iPhone 12 and 12 mini (6.1-inch and 5.4-inch, respectively) brought OLED to all models with Super Retina XDR (460 PPI). The 12 Pro and 12 Pro Max (6.1-inch and 6.7-inch) added Ceramic Shield for durability. All models supported HDR and True Tone, with sharper visuals across the board.
iPhone 13 Series (2021)
The 13 and 13 mini retained the 12’s display specs but increased brightness (800 nits typical). The 13 Pro and 13 Pro Max introduced ProMotion, a 120Hz adaptive refresh rate, making animations and scrolling buttery smooth. The notch shrank by 20%, enhancing immersion.
iPhone 14 Series (2022)
The iPhone 14 and 14 Plus (6.1-inch and 6.7-inch) used Super Retina XDR OLED with improved efficiency. The 14 Pro and 14 Pro Max debuted the Dynamic Island, replacing the notch with an interactive UI element. ProMotion and Always-On Display (AOD) were exclusive to Pro models.
iPhone 15 Series (2023)
The iPhone 15 and 15 Plus adopted the Dynamic Island and boosted brightness to 1000 nits (2000 nits peak). The 15 Pro and 15 Pro Max refined ProMotion and AOD, with slimmer bezels and titanium frames complementing the 6.1-inch and 6.7-inch OLEDs.
iPhone 16 Series (2024)
The iPhone 16 and 16 Plus maintained 6.1-inch and 6.7-inch Super Retina XDR OLEDs with Ceramic Shield. The 16 Pro and 16 Pro Max pushed sizes to 6.3-inch and 6.9-inch, respectively, with even thinner bezels and peak brightness of 2500 nits for HDR. ProMotion and AOD remained Pro-exclusive.
Key Trends and Innovations

Brightness and Durability: Steady increases in brightness (up to 2500 nits) and Ceramic Shield have made iPhone displays more versatile and resilient.
What’s Next for iPhone Displays?
Rumors suggest under-display cameras and sensors for a true edge-to-edge screen, potentially by 2026. Foldable displays or micro-LED could also emerge, promising even higher efficiency and longevity. Apple’s focus on integrating hardware and software will likely keep iPhone displays at the forefront of innovation.
FAQs
Q: What’s the difference between Retina, Super Retina, and Liquid Retina?
A: Retina refers to displays with high enough PPI (e.g., 326 PPI) to make pixels indistinguishable at typical viewing distances. Super Retina (OLED) offers higher contrast and resolution (e.g., 458 PPI). Liquid Retina (LCD) is a high-quality LCD with rounded corners and True Tone but lower contrast than OLED.
Q: Why did Apple switch to OLED?
A: OLED provides deeper blacks, higher contrast, HDR support, and power efficiency, especially for dark content. It also enables thinner designs and features like Always-On Display.
Q: Which iPhones have ProMotion?
A: ProMotion (120Hz refresh rate) is available on iPhone 13 Pro, 13 Pro Max, 14 Pro, 14 Pro Max, 15 Pro, 15 Pro Max, 16 Pro, and 16 Pro Max.
Q: What is the Dynamic Island, and which models have it?
A: The Dynamic Island is an interactive UI element that replaces the notch, displaying notifications and app controls. It’s available on iPhone 14 Pro, 14 Pro Max, 15, 15 Plus, 15 Pro, 15 Pro Max, 16, 16 Plus, 16 Pro, and 16 Pro Max.
Q: Are iPhone displays durable?
A: Yes, especially models from 2020 onward with Ceramic Shield, which offers up to 4x better drop protection. However, scratches can still occur, so screen protectors are recommended.
This journey through iPhone display technology highlights Apple’s relentless pursuit of visual excellence. Whether you’re a casual user or a tech enthusiast, the evolution from LCD to OLED and beyond is a testament to innovation that keeps us glued to our screens—literally and figuratively.
