Apple is expected to unveil three new phones at its big press event tomorrow: the iPhone 8 and iPhone 8 Plus, both likely to feature the standard LCD display, and the iPhone X, a dramatically redesigned device with a nearly bezel-free OLED screen, Face ID, 3D camera sensors, and new animated emojis. The iPhone X, said to reference the 10th anniversary of the debut of the original iPhone in 2007, is expected to be priced at just about $1,000.

These and other details about the new Apple devices were found in several leaks that came out over the past few days, including a leaked Golden Master (GM) of iOS 11. The GM is the final version of operating system software made available to developers before a new OS is publicly released.

In addition to revealing new details about the latest iPhones, Apple is also expected to take the wraps off a new Apple Watch, an updated Apple TV, the coming HomePod intelligent home speaker, a new iMac Pro, and other devices. Set to begin at 10 a.m. Pacific Time on Tuesday, Sept. 12, the event will also be the first held in Apple's new Steve Jobs Theater in Cupertino, Calif.

Light-Adjusting Display, Animated Emojis

This weekend's Apple leaks quashed several earlier rumors that had long been circulating about the company's latest phones. Previously, the new OLED device was said to be called either the iPhone 8 or the iPhone Edition, while the LCD devices had been expected to be named the iPhone 7s and 7s Plus.

In its analysis of the leaked iOS 11 Golden Master, 9to5Mac on Friday said the firmware showed the iPhone X appears to feature Apple's True Tone display technology. Introduced with last year's 9.7-inch iPad Pro, True Tone automatically adjusts brightness and color as ambient lighting changes to provide a screen reading experience that's more like print on paper.

The camera of the iPhone X will also likely come with several updates, including a beta version of Portrait Lighting for more advanced photographic capabilities. The camera will also offer new resolution and capture speed capabilities for video recording.

Another new feature that seems to be on the way with Apple's iPhone X is something called Animoji, animated 3D emojis for use with iMessage. Based on the iPhone X's 3D sensors, the animation technology will enable users to create personalized emoji expressions through facial recognition and tracking.

New HomePod, Apple Watch, Apple TV Details

Tomorrow's Apple event will also likely reveal more details about the coming HomePod, an intelligent home speaker that's similar to the Amazon Echo or Google Home. Priced at $349 and set to be released in December, the voice-controlled HomePod will provide intelligent responses powered by Apple's Siri digital assistant. Other new devices expected to appear tomorrow include a 4K Apple TV and a new Apple Watch that supports LTE cellular communication.

The first look at Apple's new Steve Jobs Theater should also generate some headlines. The 1000-seat underground auditorium will be state-of-the-art, with $14,000 leather seats, and a product demonstration room that can stay hidden from the audience until a retractable wall is opened, according to The Mercury News.
