IPhone 13 – Good Grades
DisplayMate is the premier and most respected source for display evaluation and has been evaluating displays since 1991, so a thumbs up for a smartphone display is a very credible positive. DisplayMate recently evaluated the display for Apple's (AAPL) iPhone 13 Pro Max, the top of the line smartphone from Apple this year. We believe the display was produced by Samsung Display and sets a few records as to performance.
While the display size (6.7”), resolution (1284x2778), and pixels/in (458) remained the same as the iPhone 12, given that the previous display was ‘perfectly sharp for 20/20 vision’, further enhancements to those parameters was unnecessary, however there were some improvements that are noteworthy. The iPhone 13 Pro Max has a maximum refresh rate (how many times the screen is ‘repainted’ each second) of 120 Hz as opposed to the previous year’s 60 Hz. and adapts to the image content, using the highest rate for full motion high resolution video and a rate as low as 10 Hz for static images. While the pixels are still updated at the higher rate, the slower screen refresh saves power, a necessary consideration given the display itself can use up to 80% of the total system power draw, so any improvement in power consumption works toward improving time between charges.
The iPhone 13 Pro Max display maximum brightness has also improved from last year’s model, by 27% which when coupled with screen reflectance, which is rated as ‘excellent’, determines the device’s readability in ambient light. As the iPhone 13 Pro Max has improved both, it is considered one of the best designs for outdoor use. Among the other performance achievements made on the iPhone 13 ProMax display are:

- Highest Absolute Color Accuracy – “Visually indistinguishable from Perfect”
- Highest Contrast Ratio – “Infinite”
- Lowest Screen Reflectance – 4.6%
- Smallest Brightness Variation with Viewing Angle – 24% at 30⁰
