AR devices are equipment used for augmented reality and are now widely applied in fields such as education, industry, healthcare, and entertainment.
Taking children's education, which families are most concerned about, as an example, AR devices can create immersive learning environments for children. Virtual historical scenes and scientific experiments can be superimposed in the classroom, enabling children to understand abstract knowledge as early as possible from a young age.
In other fields, representative products of AR devices include Microsoft HoloLens, Magic Leap, and Apple Vision Pro, etc. Especially after the latter was launched on the market, it has attracted the attention of consumers worldwide.
AR devices are composed of components such as a display system, camera, gyroscope, accelerometer, processing unit, and input device. Among them, the core display system mainly uses near-eye display technology (such as Micro OLED displays) as the mainstream.
So, what kind of Micro OLED display is most suitable for AR devices? Next, from the perspective of market demand, we will conduct an in-depth analysis of the factors that AR device manufacturers consider when choosing Micro OLED displays.
The Micro OLED display most suitable for AR has the following characteristics:
The purpose of AR technology is to augment reality, which requires virtual images to achieve an extremely high resolution so that people cannot distinguish between virtual and real images, thereby enhancing the sense of reality.
For example, the Micro OLED display used in Apple Vision Pro is 1.3 inches and can achieve a 4K resolution on the screen. However, a 4K resolution Micro OLED with a 1.3-inch size has an excessively high cost and is not suitable for most mid-range device manufacturers.
For most AR device manufacturers of this kind, seeking a Micro OLED display with sufficiently high performance, stable performance, and a relatively low cost has become the main direction. A cheaper price of AR devices can also make the products more acceptable to middle-class consumers.
For instance, the 0.71-inch Micro OLED produced by MOT is even smaller in weight than that used in Apple Vision Pro, which can make AR devices lighter and more comfortable to wear.
In addition, its 2.5K*2.5K resolution has already met the extremely high resolution requirements. For most consumers, using an AR device with this resolution is already a very top-notch visual enjoyment.
Many AR applications are used outdoors during the daytime. This means that ordinary OLEDs cannot achieve the desired virtual reality effect on sunny days due to insufficient brightness. Users of Apple phones should be well aware of this: when we move from a shaded area to the outdoors, the screen brightness will adapt to a suitable level, and this is the very principle.
The Micro OLED display has broken through the bottleneck of traditional display technologies and has a very high brightness. Generally speaking, the brightness of AR devices used outdoors needs to reach around 5000 nits.
| Light Condition | Minimum Brightness Requirement |
| Indoor (controlled lighting) | 200 - 500 nits |
| Semi - outdoor (some exposure to sunlight, not direct) | 500 - 1,000 nits |
| Full outdoor (in direct sunlight) | At least 1,500 nits |
To use AR devices in real-world environments, high contrast is required to make the display effect more realistic. Currently, the ANSI contrast of some relatively mainstream Micro OLED displays reaches a level of over 600. And a wider color gamut can accurately restore the rich colors of objects, making the colors of virtual images more vivid.
The Micro OLED display designed and manufactured by MOT Company has an ANSI contrast of 900, which is suitable for the vast majority of usage scenarios.
The NTSC color gamut of the Micro OLED display has a gray level of >85%, indicating a relatively high color performance ability.
Since AR devices require excellent synchronization during use. If there is image delay, it will inevitably affect the user experience of the device and may even cause users to feel dizzy.
According to data from VR, to reduce the feeling of dizziness, the refresh rate of VR devices needs to be increased to 150 - 240Hz and above. The refresh rate of Micro OLED can reach 120Hz, which can meet such a refresh rate requirement and reduce image ghosting.
Especially when displaying rapidly changing images, it can enable users to feel that the virtual content is synchronized with their head movements and changes in the real scene.
In addition, the pixel response speed of Micro OLED is in the microsecond level, which is higher than that of Fast-LCD and LCoS in the millisecond level, and this is one of its main advantages.
For example, the arpara VR device is equipped with two 1.03-inch Micro-OLED displays, with a monocular resolution of 2560×2560, a PPI of 3514, a PPD of 32, and a field of view of nearly 95 degrees. The Micro-OLED screen it uses has a faster response time, avoiding the occurrence of ghosting.
For consumer-grade products, AR devices are required to be comfortable to wear. This requires that their main component - the display screen, should be small in size and light in weight to reduce the burden on users.
It is recommended that the size of Micro OLEDs for wholesale purchase is preferably between 0.75 inches and 1 inch.
Eyewear-style wearing: Such as Nreal Air and Rokid Max AR glasses. These devices are shaped like ordinary glasses, with the nose pads supporting on the bridge of the nose. If the AR glasses are too heavy, it will undoubtedly impose a burden on the bridge of the nose and the ears.
Head-mounted wearing: Such as Microsoft HoloLens. This kind of head-mounted device is relatively heavy, and long-term wearing will cause a sense of pressure on the head.
Therefore, this type of device places a greater emphasis on the lightweight size of the Micro OLED.
It helps to extend the battery life of AR devices, facilitating users to use them for a long time. The Micro OLED display, based on the silicon backplane technology, can achieve relatively low power consumption.
| AR Device | Battery Life |
| Microsoft HoloLens 2 | About 2 - 3 hours under normal use, and up to 5 hours in specific light - use scenarios |
| Magic Leap 2 | About 3 hours |
| Nreal Air | About 4 hours |
| ThinkReality A3 | 3.5 hours |
| Leiniao X2 | 8 hours |
| LiGlass 1 | 9.5 hours in comprehensive working conditions |
With its exclusive FSL technology, MOT provides global manufacturers with solutions that combine high performance, low power consumption and cost-effectiveness.
It not only achieves the high performance and low power consumption of silicon-based OLEDs, but more importantly, solves the biggest problem faced by silicon-based OLEDs — the cost issue, clearing the obstacles for their mass production and reducing the overall costs for VR and AR manufacturers.
