Microsoft files new MicroLED display for HoloLens 2 successor – XR Today

Microsoft has reportedly filed a new patent to develop a micro-LED display solution to improve virtual, augmented and mixed reality (VR/AR/MR) experiences.

A report from MS Power User revealed that Microsoft’s latest patent is aimed at improving the performance of devices like the HoloLens 2 and more, indicating a potential revival of its research and development (R&D) push.

In it, Microsoft filed a display technology patent that continues the innovations of US11688333B1, which Microsoft filed in June and which the US Patent and Trademark Office (USPTO) approved on October 19.

Inventors Charles Walter Boecker, Niranjan, Achugundla Puttaswamy, Barry Thompson, Sheethal Somesh Nayak, Jeffrey Neil Margolis and Chuan Puaim to create a display device [that] It consists of a display substrate and a backing substrate.

The original patent is pending.

The substrate of the display consists of a set of micro-LEDs that form individual pixels. The Backplane platform consists of a large number of pixel logic hardware modules. Each pixel logic hardware module includes a local memory element configured to store a multi-bit pixel intensity value of a corresponding micro-LED for an image frame. The backplane substrate is bonded to the back of the display substrate so that the pixel logic hardware modules are physically placed behind the micro LED array and each pixel logic hardware module is electrically connected to a micro LED of the corresponding pixel. to be

Also, the report states that Microsoft will explore microLED displays to circumvent some of the problems of waveguide technologies, including size and poor visual quality. In addition, the use of microLED displays can reduce the form factors of the HoloLens device, while increasing the image quality of the headset.

The news comes after several patents revealed that Microsoft has filed patents for hot-swappable batteries for an AR smartglass device, indicating an attempt to revive AR head-mounted displays (HMDs).

Apple-Microsoft-Meta micro-OLED melee?

News of the patent comes amid a battle between the top manufacturers of mixed reality headsets. Recent updates ahead of the Meta Connect 2023 event revealed that the company has partnered with South Korea’s LG Electronics to develop a successor to the Quest Pro.

According to Maeil Business Newspaper, Meta has partnered with the Seoul-based tech giant to build micro-organic light emitting diode (micro-OLED) displays for the experimental title Meta Quest 4 Pro.

LG will also supply device batteries and spare parts to LG Innotech. In addition to supplying components for the upcoming device, LG will also participate in and manage the manufacturing of some of the Menlo Park-based company’s activities.

Along with the upcoming successor to the Quest Metas, Apple has kicked off its Vision Pro headset innovation with a successor that costs much less than the $3,499 price tag of the first-generation devices.

To deal with future headset price hikes, Apple struck deals with Chinese micro OLED display makers SeeYA Technology and Best on Earth (BOE).

In a report, sources familiar with the matter stated that Apple has tested advanced displays from both companies and plans to include them in future models of the Vision Pro head-mounted display (HMD).

Also, the initial release of Apple’s Vision Pro with micro-OLED displays has been hampered by Sony not being able to deliver more than a million units and each unit requiring two to function.

To date, news reports have found that Apple plans to patent a pair of augmented reality smart glasses that could enhance AR development and integration capabilities, leading to the next step towards a more immersive adoption rate.
