Fraunhofer FEP will show bidirectional AR / VR head mounted display devices based on OLED microdisplay.

Fraunhofer FEP announced that they would show bidirectional AR / VR head mounted display devices based on OLED microdisplay at AWE Europe 2017 from October 19-20. According to Fraunhofer FEP, OLED microdisplay supports SVGA (800 x 600) resolution and can display augmented reality and virtual reality of 2D and 3D content via USB interface and HDMI connection. In addition, it is known that it is possible to use an eye tracking system that uses a photodiode to detect a user’s gaze.

Judith Baumgarten, developer of Fraunhofer FEP, commented, “This exhibition will showcase the quality and versatility of OLED microdisplay,” he said. “It will be a great opportunity to demonstrate Fraunhofer FEP know-how in electronic design.”

In the meantime, AR/VR devices have been developed mainly in the fields of entertainment and games. Fraunhofer FEP, however, is expected to support designers, engineers, surgeons, etc. and enable them to be used as educational media in almost every field.

On the other hand, augmented reality and virtual reality technology are attracting great attention as one of the main technologies of the 4th industrial revolution that has recently attracted attention, and products such as Oculus Rift and Gear VR are continuously being released. According to UBi Research, the AR/VR market will expand full scale in 2019, when 5G is introduced, which can mass-produce UHD contents and transfer large volumes of content fast and the total revenues of virtual reality and augmented reality products will reach $ 58.7 billion by 2021.

AR and VR Market, Active Expansion in 2019 – What Propels the Growth?

  • Forecast of US$ 58,700 million of total revenue of AR and VR in 2021
  • Active expansion expected in 2019 with UHD contents mass production and fast transfer of large size content for VR through introduction of 5G

 

With recent ICT (Information and Communication Technologies) progress, fourth industrial revolution is receiving attention as the new growth engine. Along with the increased interest in augmented reality (AR) and virtual reality (VR), products such as Oculus Rift and Gear VR continue to be released.

Released AR products include glass types such as Microsoft’s HoloLens and Google’s Google Glass. HMD (Head Mounted Display) based VR type products include Oculus VR’s Oculus Rift, HTC’s Valve, and Sony’s PlayStation VR, and smartphone based VR types include Samsung Electronics’ Gear VR.

According to AR and VR Display Market Report published by UBI Research on 7th, AR and VR product shipment is expected to record 17 million units in 2017 with US$ 3,900 million revenue. UHD contents mass production and introduction of 5G for fast processing large size VR content are expected from 2019. Accordingly, total shipment of AR and VR products is estimated to increase at approximately 54% CAGR, and show 96.4 million units of shipment and US$ 58,700 million revenue.

The report divided the market by product and display for AR and VR market analysis, which is further categorized into AR and VR product total market, market by VR product, AR and VR use display total market, AR and VR use OLED, and market by other display type.

For immersive virtual reality experience without dizziness, display conditions such as latency, FOV, refresh rate, and high resolution were selected as key issues and were analyzed. AR and VR products released between 2014 and 2016 were arranged by types, categorized by display type and key companies and analyzed.

Furthermore, business status of key IT companies, including Apple and Facebook, is included handling AR and VR product release status, related patent, and related company takeover. With the information on key panel companies’ AR and VR product exhibition status, the report is expected to be conducive to understanding key trends of related companies.

UBI Research estimates AR and VR use OLED shipment to be 2.6 million units in 2017, with 2.4 million units of other displays. OLED is expected to show 52% of market share with 48% of other display. In 2021, AR and VR use OLED is expected to show shipment of 52 million units and occupy 80% of the market.

OLED, the mainstream of HMD devices for VR

The ‘PlayX4’ opening ceremony, a next-generation augmented game show, was held at Kintex exhibition hall 2, Ilsan, Goyang, Gyeonggi-do on the 25th. During the event, a number of companies presented VR contents, using HMD (head mounted display) devices in application of OLED, such as Oculus Rift, HTC Vive and Gear VR to improve immersion and reduce motion sickness.

Realitymagiq, a professional of VR game developer, introduced a multiplay game. In reply to a question on immersion into VR, “Device performance is essential for immersive in VR, and to reduce latency, the major culprit for sickness, OLED is more than enough,” said Kim Sung-kyun, the CEO of Realitymagiq. “However, resolution needs to be further developed and so does GPU performance.”

Motionhouse Co., Ltd. has introduced MotionGear for users to experience tilting and engine vibration during actual driving. Oculus Rift OLED-applied headset, was used; “Oculus Rift was the one that could minimize the motion sickness most”, said a participant.

Latency refers to the time length for the CPU to receive information from the tracker and output, which is related to the response time of the display and the information processing of the graphics card. The response time of the display required in VR is known to be less than 3ms. Samsung Display compares the response time between OLED and LCD on the blog and emphasizes that OLED is the optimal display for VR HMD device.

In fact, many VR content companies used OLED-applied HMD devices such as Oculus Rift, HTC Vive, and Gear VR, and users seemed to enjoy VR game, not suffering from dizziness

Recently, aside from Oculus Rift and HTC Vive, many HMD makers such as recently launched Sony’s PS VR and Royole’s Royole Moon are OLED-based, not LCD, and surely the OLED application is expected to expand further.

HUD and HMD Meet Virtual Reality and Soar

At SID 2015 Review Workshop held in Konkuk University on July 31, Inha University’s Associate Professor Jae-Hyeung Park announced that interest in HUD (head-up display) and HMD (head-mounted display) increased at SID 2015.

 

HUD signifies technology that provides diverse information for the driver beyond the role of a front glass that simply allows the outside to be viewed and provides protection. Through HUD, drivers can grasp vehicular and destination information without having to take eyes off the road. At this juncture, AR (augmented reality) HUD is more than a simple display as it recognize the user’s movements and applies it to the display.

 

In SID 2015 paper, Japan’s Ricoh termed the device that self-intervenes in the vehicular operation as ADAS (Advanced Driving Assistance System) and announced that the information from the device applied to HUD will be able to help the user’s recognition and decision making. It was also added that improved AR can be realized when the contrast range is increased to be equal to reality and reiterated and the distance from the virtual image is 5m.

 

HMD, as a head-mounted device, provides differentiated feelings of immersion compared to other displays. Due to the increased realism from the wide viewing angle, HMD was widely used as an entertainment display, but with the recent increased interest in AR, it is receiving much spotlight as an AR display device.

 

At SID 2015, the West Saxon University of Applied Sciences of Zwickau revealed an HMD device that actualizes AR naturally by changing the distance where image is shown according to the use by adjusting the focal distance. Zhejiang University’s college of Optical Science and Engineering used method of showing hologram to each user’s eyes using the light field concept that realizes the light strength to all directions from all points in 3D and produced improved AR.

 

Park explained that with SID 2015 as a starting point, the AR related HMD and HUD interest and research will increases greatly and that the trend will continue in future.

 

Samsung Electronics released HMD device Samsung Gear VR that can be used by plugging in to Galaxy S6 or Galaxy S6 Edge. Oculus VR and Sony Computer Entertainment each revealed OLED applied VR headset Oculus Rift and Project Morpheus, and scheduled release regular product in Q1 and H1 of 2016 respectively. Korea’s HLB released AproVIEW S2 which used virtual image distance actualization method, a first for HUD.
