さらに、インテリアディスプレイには全てOLEDが採用された。OLEDはLCDに比べ、高いコントラスト比と速い反応速度、広い視野角を持ち、高い視認性を実現することができることから、車載用ディスプレイに適合するという評価を受けている。

自動車部品サプライヤー(部品製造業者)のContinental corporationも自社ホームページで、2枚のOLEDを搭載したミラーレス自動車の様々な利点を紹介し、暗い状況や雨天時にも快適な視野を提供することができると明らかにしたことがある。

一方、Samsung DisplayやLG Displayのみならず、中国のパネルメーカーも市場攻略に向け、多彩なOLED製品を披露している。

Samsung Displayは先日5月に開催されたSID 2018で、OLEDを活用して画面を様々なサイズに調整できるRollable CID(Center Information Display)と12.4型サイズのCurved CIDを展示した。

車載用ディスプレイはモバイル機器やTVと比較し、より多くのカスタマイズが必要なため、高付加価値の創造が期待される産業として注目を集めている。

Samsung Electronicsは、6月初にシンガポールで開いた投資家フォーラムで、車載用OLEDパネル事業を未来事業として強調し、「今年10万枚だった車載電装用OLEDパネルは、2020年に100万枚、2022年に300万枚にまで増える」と展望を示したことがある。

Absolute Requirements for the Automotive OLED Display’s Success

On October 15, in IMID Exhibition Business Forum held in Korea International Exhibition Center (October 14-16), KATECH (Korea Automotive Technology Institute)’s head of Intelligent Control System R&D Center Dr. Inbeom Yang presented ‘Future of Automotive Technology and the Role of Smart Display’ and forecast the future of automotive display.

 

Dr. Yang revealed that “if existing vehicles focused on technological factors, future vehicles will evolve entirely centering on the driver, and the automotive display also will develop following this trend”. He also added that the driver’s safety and convenience have to be the priority.

 

Dr. Yang gave 4 examples of future automotive display. Firstly, he discussed ADAS and their flaws. ADAS (Advanced Driver Assistance Systems) help the driver to operate the vehicle safely. If ADAS can be actualized through displays such as HUD (head-up display), the driver’s safety can be maintained with ease.

 

The second item mentioned was a function that notifies the driver status reports linked with time and location. Dr. Yang reported that a device needs to be developed that can function in specific situations with sensors and sounds as well as on display.

 

Dr. Yang forecast that if display, touch technology, and haptic technology are combined and applied to vehicles, operation and feedback will be simpler for the driver. He announced that multi-functional & configuration display will also be introduced which will allow driver to recognize and control.

 

Audi’s concept vehicle that was presented in IAA 2015 Audi e-tron quattro has full OLED interface and all functions required for the vehicle operation can be controlled via touch display without physical buttons.

 

As futuristic displays such as these are developed that increases driver’s convenience, the proportion of display within a vehicle is expected to increase, and developed focusing on the driver centered UI (user interface). OLED Display can maximize the driver’s accuracy with fast response rate and high contrast ratio. Along with safety, and design freedom that comes with flexibility, it is suitable for automotive display. However, the linkage with the UI system optimized for the driver is essential rather than performance of the display panel itself; collaboration between display panel companies, and automotive system and peripheral companies is expected to be a major point in early market occupancy between automotive display panel companies.

[IAA 2015] Audi and Porsche, Propose Future Models of Smart Car

At IAA 2015 (September 17 – 27), Audi and Porsche presented OLED lighting and display equipped vehicles.

 

In the past, Audi has proved OLED technology’s excellence through diverse models and demonstrations, including introduction of ‘swarm’ in 2013 with its 3D OLED car rear lighting panels. At this motor show, Audi revealed Audi e-tron quattro, the first concept car with Matrix OLED technology. As well as the Matrix OLED lighting, interior OLED display was also applied to the concept car. Audi explained that the Matrix OLED lighting, which was applied to the rear lighting, can continuously change lights and does not cast shadow. Full OLED interface was also applied to the car and all functions required in driving can be control by display touch. Audi revealed that they will gradually apply these technology to next generation Audi series.

 

Porsche presented their first four-seat electric sports car Mission E as a concept model. The instrument cluster for this concept car is displayed virtually in OLED. The menu can be activated through buttons on the handle. It can also be automatically activated as the cluster’s eye tracking system can perceive the driver’s attention. The display also follows the seat position and body attitude of the driver in what is known as a parallax effect; the display moves according to the driver’s posture for easier viewing. Porsche revealed that Porsche Car Connect technology will also be applied which will allow the user to control key functions of the vehicle through a smartphone.

 

As OLED using lighting and display are actively applied to smart cars, attention on the automotive OLED is also increasing. At the National Research Development Industry General Workshop, held in July 2015, Samsung Display and LG Display each stated their thoughts on display that will be applied to future smart cars.

 

Samsung Display’s executive director Hye Yong Chu asserted that smart is display’s future, including smart car. She also explained that for the actualization of smart technology, other ancillary smart technology, such as eye tracking and voice recognition technology, are required.

 

Yoon Sooyoung, LG Display’s vice president, stated that automotive display can be used for CID, dashboard, cluster, and window, and that the development of transparent and flexible technology is necessary.

 

During the keynote session of IMID 2015, Munhyun Kim of Hyundai Motors revealed that OLED panels will mainly be applied to smart car compared to LCD as it can easily be flexible. He also added that the automotive OLED’s percentage within the total OLED market will increase, and anticipated that it will exceed 30% in 2017.

[Geneva International Motor Show 2015] Vehicle Display for Driver’s Comfort

By Choong Hoon Yi

 

One of top 5 motor shows in the world, Geneva International Motor Show 2015 has opened, with approx. 220 companies from around the world exhibiting around 900 cars.

150309_[Geneva Motor Show 2015] 운전자 편의를 고려한 자동차용 디스플레이1The basic function of a vehicle is to transport people or cargo. However, recent commercialized vehicles have car information system on top of basic driving function. This allows the driver to understand various information while driving.

Vehicles exhibited in Geneva International Motor Show can largely be divided into sports car, sedan, and SUV, and separated into gasoline, diesel, and HEV according to its source of energy. The key focus of this motor show is environmentally friendly car conforming to the EU’s carbon emission quantity. The majority of cars that can accommodate the EU’s standard of 130g/km are HEV and diesel. Volkswagen, Lexus, and Benz exhibited cars that comply with EU standard in large quantities.

150309_[Geneva Motor Show 2015] 운전자 편의를 고려한 자동차용 디스플레이The key point of the 21st century vehicles are various methods of information processing integrated with IT technology as well as the environment issue. This is obviously a device where a display, an information medium, is important. What kind of displays are being used by the latest cars exhibited in the Geneva International Motor Show? The vehicular display can be divided by its uses: dashboard, information, and entertainment. Dashboard display performs the existing function of showing the speed and vehicular conditions. Information display is granted with audio function including navigation. Entertainment display is for the backseat passenger who will be able to play games or watch TV while the car is moving.

In the IoT era, the information display holds the most important place of the 3. When the driver is processing various information, including navigation, via information display, the driver’s attention has to move away from the road to the center of the car. Even if this occurs for the shortest amount of time, there is a danger of an accident. Better the vehicle, it minimizes the damage to people in accidents by limiting the shock through the main body and air bags. What would be even better is a system that prevents the accident in the first place. Electronic control such as ABS system and breaks are such systems. Although various safety devices are within the vehicle, if the driver’s attention moves away from the road ahead, the likelihood of an accident inevitably rises. The use of information display such as navigation system can be a factor that increases the possibility of an accident.

The location of the vehicular information display sold by companies all over the world is essentially below central ventilation system; the eyes have to move downward while driving. Companies that are more mindful of the drivers place the information display on the same level as the vents. Of course, the best system is the one where the display is located above the ventilation so that the driver’s eyes can be closest to the front.

Where do world’s famous brands such as Benz, BMW, and Audi have their information display?
