The worst stored secret in Silicon Valley was revealed at Apple’s WWDC 2023 convention when the Imaginative and prescient Professional headset was revealed.
Apple’s alternate actuality/digital actuality headset has ambitions of providing an unrivalled expertise in comparison with the competitors, and a method it goals to realize this goal is thru the 2 Micro OLED screens that it makes use of for its show.
So what’s Micro OLED and why has Apple chosen the tech for its first foray into VR headsets?
What’s Micro OLED?
Micro OLED, or micro-OLED because it’s additionally referred to, is a silicon-based show that makes use of monocrystalline silicon wafers because the backplane (primarily a circuit board). The Natural Mild Emitting Diodes (or OLED) sit on prime, and hundreds of those might be added.
The extra OLEDs there are, the upper the pixel density might be. Due to this fact a 0.5-inch show with Micro OLED can attain as much as 4000 pixels per inch (ppi) in comparison with 580 ppi on a smartphone with a 5-inch show. That’s a giant improve in decision, sharpness and element.
What does that imply for the Apple Imaginative and prescient Professional?
The backplane makes use of Apple Silicon with an RGB (Purple Inexperienced Blue) association, with Apple Expertise Growth Group VP Mike Rockwell saying that for each pixel on an iPhone there are 64 extra on the Apple Imaginative and prescient Professional.
This provides as much as 23 million pixels packed into two shows, each the scale of a postage stamp. The Apple Imaginative and prescient Professional helps broad color and excessive dynamic vary. Apple declare that in its cinema mode you could possibly have a 100ft display screen sitting in entrance of you to observe movies on.

What else is Micro OLED used for?
There’s been plenty of curiosity in utilizing Micro OLED for different actuality (AR) and digital actuality (VR) shows as a result of they’re smaller, and due to this fact could make the headset design much less cumbersome and lighter to put on.
They’re additionally generally used as digital viewfinders (EVF) in cameras, in addition to headsets for drone racing.
It’s unlikely the expertise can be used for bigger display screen units similar to TVs. The dimensions, value and manufacturing course of required can be huge, and in addition as a result of the pixel density wouldn’t be of as a lot use at regular TV viewing distances. Micro OLED is finest served for sustaining prime quality photographs at an in depth distance, so it will appear as if the way forward for this tech lies in VR.
