A brand new teardown of Apple’s newest iPad mini by iFixit discovered a clue which will clarify the “jelly scrolling” impact that among the pill’s customers have complained about.
In case you missed our previous protection on the topic, some iPad mini customers seen a refined, stagger-like disconnect between the suitable and left sides of the display when scrolling by way of content material. Some individuals see it immediately, others must have it identified to them, and others nonetheless do not discover even when informed.
After we wrote about it, Apple commented on the story to us saying that the impact is anticipated. From our coverage:
In response to our inquiry, Apple has informed us that the “jelly scroll” problem on the Sixth-generation iPad mini is regular conduct for LCD screens. As a result of these screens do refresh line by line, there’s a tiny delay between when the traces on the prime of the display and contours on the backside are refreshed. This could trigger uneven scrolling points like those noticed on the iPad.
When tearing the mini down, iFixit discovered that the controller board that drives the pill’s show is oriented vertically. In contrast, the iPad Air’s is oriented horizontally. iFixit means that the jelly scrolling impact happens when the pill’s orientation would not match the location of the controller board, as a result of the line-by-line refresh additionally occurs relative to that board’s orientation.
Certain sufficient, slow-motion footage of the iPad mini reveals the jelly scrolling in portrait mode (a vertical orientation) however not in panorama (a horizontal one). And the iPad Air additionally reveals jelly scrolling in the identical check; it simply does so within the horizontal orientation as an alternative of the portrait one.
The iPad Professional has a vertically oriented show controller board. Whereas one other video check confirmed that the jelly scrolling was nonetheless occurring on that pill in portrait mode identical to the mini, the Professional’s 120Hz refresh fee all however masks it to most human eyes. All that’s to say that whereas the impact could also be extra noticeable on one system than one other, it is not uncommon in any OLED or LCD show, iPad or in any other case.
Latest on-line controversy in regards to the iPad mini’s jelly scrolling apart, iFixit’s teardowns are normally targeted on exploring how simply repairable units are. The iPad mini obtained a 3 out of 10 for repairability. Earlier this week, iFixit additionally tore down the iPhone 13 Pro and gave it a 6 out of 10.
