This morning, Apple shared a new support document discussing the Super Retina OLED display in the iPhone X.
The documents addresses viewing angles, as well as the possibility of image persistence. In the support document, Apple said:
“If you look at an OLED display off-angle, you might notice slight shifts in color and hue. This is a characteristic of OLED and is normal behavior.”
The manifestation should only occur when a device is being used by two people at once. The “shifts in colour and hue” are very slight at narrow angles, and worsen slightly the farther away from a straight-on viewing angle the user gets. Apple writes:
“With extended long-term use, OLED displays can also show slight visual changes. This is also expected behavior and can include ‘image persistence’ or ‘burn-in,’ where the display shows a faint remnant of an image even after a new image appears on the screen.”
Apple advises users to avoid continuously displaying the same high-contrast image for prolonged periods of time. The company also notes that it has engineered the display to reduce the effects of OLED “burn-in.”
The OLED burn-in “issue” isn’t new, and isn’t permanent with well-engineered panels. Evidence collected over the last few years demonstrates that retained images are wiped over a brief period of normal time of normal use displaying non-static elements.
Over the past week, the Google Pixel 2 XL has been receiving some criticism over burn-in issues on its OLED screen. This is partially to do with the screen which is based on LG’s pOLED technology. However, the Pixel 2 has not been showing any problems because the display of the smaller device is based on Samsung’s AMOLED processes.
