Apple Glasses displays for use with micro OLED; in sample production



The Apple Glasses screens are expected to be micro-OLED screens, it is stated in a new report today. Not to be confused with microLED, micro OLED is an advanced form of display technology built directly on chip wafers, and is ideal for the very small screens that are likely to be used in Apple’s augmented reality glasses.

The Cupertino company has reportedly been working on the project with chipmaker TSMC in the A-series under conditions of secrecy that are extreme even by Apple standards …

While the Cupertino company is reportedly planning to launch an advanced VR / AR headset first, it is believed that this is just a springboard towards a mass market consumer product that has been called Apple Glasses. This is expected to be a device that looks like conventional glasses, but with small built-in screens to add information such as map directions, messages, app alerts and so on.

Nikkei cites separate sources for the report.

Apple has entered into a partnership with Taiwan Semiconductor Manufacturing Co. to develop ultra-advanced display technology at a secret facility in Taiwan, Nikkei Asia learned […]

7;s complex in Longtan Science Park consists of several unmarked white buildings – there is no company logo or address on the outside, and only a very faint apple symbol could be seen in the lobby, Nikkei journalists saw on a recent visit. Apple registered a company in the park in 2014, and expanded it in 2020. The complex is within walking distance of TSMC’s advanced chip packaging and testing facility, which is located in the same science park. […]

The California giant plans to develop micro-OLED displays – a radically different type of display built directly on chip wafers – with the ultimate goal of using the new technology in its upcoming augmented reality devices, sources said in the case.

Apple is partnering with its longtime chip provider TSMC because micro-OLED screens are not built on glass substrates like the conventional LCD screens in smartphones and TVs, or OLED screens used in high-end smartphones. Instead, these new monitors are built directly on wafers – the substrates on which semiconductors are made – enable monitors that are much thinner and smaller and use less power, making them more suitable for use in portable AR devices, according to sources familiar with projects .

Although micro OLED is a different technology than microLED, it is said that Apple works with both screen types on the same system.

Apple’s second display project on the Longtan campus focuses on micro-LED technology, which the company hopes to eventually use in Apple Watch, iPads and MacBooks. Apple has partnered with Taiwanese LED company Epistar to develop the technology.

Like micro-OLEDs, the micro-LED project also involves some technology for the production of chips. The components are 100 times smaller than those used in LED lighting products, and they do not need backlight modules such as traditional LEDs and LCD screens, which means that the screen can be much thinner. Micro LEDs also provide high color contrast and can be used to create curved or collapsible screens, such as OLED screens.

The report says that Apple Glass’ display project “is now in the trial phase”, designed to ensure that any mass production plans are realistic. It is important to note that although this is an important milestone along the way, it still represents an early stage in the project as a whole. Trial production here applies to Apple Glasses monitors, rather than the AR devices themselves.

Today’s report states that the built – in screens will be less than an inch in size, and that Apple is even more serious about confidentiality than usual.

Everyone who registers to work with the program must sign a strict confidentiality agreement that prohibits them from even meeting with friends or acquaintances who work in the technology industry, the source added.
