Is there something odd with the iPad Pro's Mini-LED screen or are you watching it wrong?
by Chandrakant Isi
It has been over a decade since the first iPad was introduced. Over the years, Apple consistently bumped up its specs with each iteration. What didn't change much, however, was the underlying display technology. Since 2010, Apple has relied on LCD screens with LED backlight for its iPad lineup. So when rumors of the Cupertino-based company embracing the mini-LED tech surfaced in 2019, fans were psyched. Websites dedicated to Apple news were quick to draw comparisons between mini-LED and OLED. Some even went as far as calling it the dream screen, and a best reason why you should buy the latest iPad Pro.
However, as the device shipped, users began complaining about a weird blooming effect on the display. Many consumers canceled their orders and even the ardent supporters described it as a "mixed verdict on mini-LED". What exactly went wrong with Apple's mini-LED display that was supposed to compete with the OLED tech?
Key differences between LCD and OLED
To understand the issue, we first need a primer on display technologies. In terms of home electronics, we experience two types of display technologies — emissive and transmissive.
OLED along with the good old CRT and Plasma tech are emissive displays where each pixel is self-illuminated and can generate colors. Since the other two technologies have been phased out, we will focus on OLED to get the point across. These panels can selectively turn off pixels to render inky blacks on the screen. Since they do away with the need for backlighting, OLED screens don't suffer from patchy brightness and light bleeding.
On the other hand, LCDs rely on backlight filtered through a layer of liquid crystal molecules, color filters, and polarizers to form an image. This particular process of rendering an image is lossy and comes with undesired side-effects such as uneven brightness, narrow viewing angles, and backlight bleeding. The biggest issue, however, is the inability to render proper blacks.
For instance, if you're watching Gravity (2013), the vastness of dark space will be rendered faithfully on an OLED screen. However, on an LCD screen, the panel's layer of liquid crystals won't be able to block backlight 100 percent. As a result, space will look more like a dark shade of grey instead of jet black.
Improving LCD's picture quality with better backlighting
To get around this shortcoming, manufacturers squeeze in more LEDs in their displays to get more granular control over backlighting. On expensive LCD panels, you get Full-Array Local Dimming (FALD) as opposed to the widely used Edge LED arrangement. As shown in the image below, a FALD display can pack in several hundred to thousand LEDs compared to a few dozen in a conventional LCD panel. More importantly, FALD panels can selectively dim or brighten up LED zones as per requirement.
How blooming comes into the picture
While this backlight technology improves an LCD's ability to produce blacks, it introduces a new issue known as blooming. This happens when the light meant for bright objects on the screen spills over the dimmed zones. Honestly, you can't expect otherwise when your Full HD FALD screen has a whopping 2,073,600 pixels (1,920 x 1,080), but only a few hundred dimming zones.
Mini-LED panel type takes it to the next level by packing in smaller LEDs in large numbers. Made possible by some impressive miniaturization engineering, this technology was first popularized by TCL on its TV line-up. For the latest iPad Pro, these mini-LED modules are manufactured by the Taiwanese company Ennostar. According to Apple's Director of HW Technologies, Heidi Delgado, the latest iPad Pro display has over 10,000 LED backlights and around 2,596 dimming zones. These mini LEDs are said to be over a hundred times smaller than the conventional ones. Since Apple hasn't shed much light on the underlying tech, here's a comparison image from TCL to put things in perspective.
At its core, the mini-LED panel is still an LCD with more refined backlighting. It is like a FALD LCD on steroids, which vastly improves the panel's contrast ratio. As highlighted in most reviews, the latest iPad Pro is undoubtedly very good at rendering deep blacks. However, along with amplifying FALD's best characteristics, mini LED also boosts its problems.
The iPad Pro (2021) has a screen resolution of 2732 x 2048, which translates to 55,95,136 pixels. While delivering 2,596 dimming zones is certainly an improvement, it is still not adequate for 5.6 million pixels. The display's 1,000 nits brightness, which is generally a good thing, also enhances the blooming artifacts. This issue didn't plague the previous-generation iPad Pro, because it had a paltry 72 LEDs. Sure, the low density of LEDs led to poor rendition of blacks but it also defused the backlight intensity over a larger area. Thus, avoiding the blooming artifact.
Can Apple fix this issue?
On the new iPad Pro, the blooming issue isn't noticeable while browsing the web, writing an email, or shopping on Amazon. It becomes jarring only when there are white objects or UI elements against a dark background. However, that's still frustrating for anyone who has spend over $1,000 for this product. It is strange that Apple failed to detect this issue during internal testing.
Even if Apple eats the humble pie, don't hold your breath for the company to patch things up over a software update. The only thing it can do now is to cap the brightness to make the blooming slightly less jarring. If the firm wants to ensure this issue doesn't crop up in future iPads, it will have to make a switch to OLED screens. With the price of current generation iPad Pro 12.9" starting at $1,100, we don't see why Apple shouldn't consider that.

Apple is shutting down Dark Sky's iOS app and website in 2022
by Fiza Ali
Apple acquired the hyperlocal weather app, Dark Sky, in 2020 and, at that time, it was highly likely that it would shut down Dark Sky's apps and website in the same year. However, the company also said that there would be "no changes to Dark Sky for iOS" at that time.
In 2021, we see that there is a small update to the Dark Sky blog that appears to be adding a new shuttering date for the Dark Sky iOS App, API, and website. Adam Grossman, the co-founder of the Dark Sky weather app, wrote:
We hear this news shortly after Apple announced an overhaul to iOS' inbuilt weather app during WWDC. While the wording on the website doesn't explicitly say that the service will be "shut down" per se, it does seem that it is reaching its end of life.
Previously, the Dark Sky website was scheduled to shut down in August 2020 while the API was scheduled to for the same at the end of 2021. Apple already killed Dark Sky's Android app back in August 2020.

Apple announces iOS 15 with notification improvements, new FaceTime features, and more
by Abhay Venkatesh
Apple today took to the stage at its WWDC conference and the first of the announcements is iOS 15. The company started off talking about FaceTime, announcing that it is bringing spatial audio to the video conferencing service. The app is also adding what the company calls noise isolation, helping silence background sounds to amplify users’ voices.
The firm also announced FaceTime links, bringing the ability to send meeting invites to users on not just iOS, but also Windows and Android to join FaceTime calls via the browser. Another new addition is SharePlay, a feature in FaceTime that allows users to share their device screens, watch content on streaming platforms, or listening to music together. The firm is also introducing APIs for streaming platforms to add support for SharePlay
Next up is Shared with you, a way to share news items and other types of content right with other users easily. These items can also be pinned in iMessages. The firm is adding support for apps like Podcast, Apple Music, Apple TV, and more for Shared with you.
Notifications are getting a major update with the addition of Notification summary. iOS 15 will summarize notifications from non-important apps to reduce clutter on the lock screen. Users will be provided the choice to select contacts and apps that can break through and display complete notifications. Notification summary uses “on-device intelligence” to tweak these summaries.
However, users can choose to turn on Do Not Disturb to block all notifications or choose the apps and contacts that can bypass the restrictions to serve notifications, thanks to Focus. Focus will also allow for adding relevant widgets with information on the home screen.
Next up is Live Text for Photos, a Google Lens-like feature that allows users to detect content from across the OS like text and look them up on the web. Users can also lookup locations from pictures, recognize characters in images, and more. Live Text works not just with images, but also with the web, and across iOS, iPadOS, and macOS.
There are updates to a bunch of apps as well, with the first being Spotlight. Apple is adding support for Photos in Spotlight, allowing users to search for images right from the home screen. The company is also adding rich information in Contacts, bringing information from services like Find My into the contact’s cards. The firm is also adding specialized cards for celebrities.
In the list of Google-inspired features, there’s the Memories feature in Photos. iOS 15 will create interactive memories based on users’ images using its on-device machine learning. It will also let users interact with the memories by adding or removing images and choose what shows up, add music, and more.
Other app improvements include added capabilities to the Wallet app that allows for storing government-issued identity cards, allowing users to carry a digital copy of their IDs. The firm is also expanding the use of Wallet as a lock or access system by leveraging the UWB technology in iPhone. These include car keys, hotel access cards, and more.
The Weather app is being redesigned with a bunch of new information, with a background that adapts to the current weather situation. Lastly, the Maps app is receiving some improvements such as a an improved design and added details for commercial buildings and more. There is also a new Nearby Transit feature and the ability to the app to notify users when it is time to disembark from public transport.
