[Automotive Display Seminar] Automotive Display, Urgent Transparent Display Technology Development Needed

By Choong Hoon Yi

 

On November 13, Automotive Display Development Technology and Commercialization Planning seminar was hosted by Educational Center of Future Technology in Yeouido, South Korea.

 

KATECH (Korea Automotive Technology Institute)’s Dr. Sun-Hong Park explained that “as the automotive display market grows, display market’s domain is expanding” and announced “market for CID (Central Information Display) that mainly functions as navigation device and HUD (Head Up Display) that can show mileage and speed is steadily growing since 2008 and it is anticipated to grow considerably in future”. He added that particularly, 7inch or larger CID is increasing its market share in display market and that CID is becoming larger. He also mentioned that with the increase of traffic accidents from driver’s lack of attention to the road, HUD that can show information on the front window is necessary. However, legibility issues due to brightness and reflectiveness and technological issues such as integration with other display device need to be solved.

Dr. Chi-Sun Hwang of ETRI (Electronics and Telecommunications Research Institute) compared display technology that can actualize transparent display, and technological issues to be solved in order for it to be applied to automotive. Hwang explained that although display technology that can produce transparent display include LCD, OLED TFEL (thin film EL), HUD (projection) among others, AMOLED is the most suitable considering resolution and transmittance. Although LCD technology level is at commercialization stage, as the transmittance is not high it can interfere with the driver’s viewing field. He also added that “poly Si TFT technology performance is good, transmittance is limited. However, oxide TFT technology’s transmittance is high and performance is continuing to improve, it needs to be more actively developed”. To be used as an automotive display, it has to meet certain conditions such as temperature, production cost, and brightness to be an automotive component as well as being placed in the suitable location in the driver’s viewing field; compared to other general display, automotive display is facing higher number of technical issues.

With the focus on the transparent display from automotive display industry, the interest in the technology needed for the application to automotive is also increasing. In order to lead the automotive display market, understanding of automotive components’ characteristics and effort to solve the diverse issues facing the optimized driving condition are required as well as knowledge of display itself.

LG Electronics Bets on OLED TV

LG Electronics actively began aggressive marketing for OLED TV.

 

In IMID Exhibition (October 14-16), LG Electronics installed an OLED comparison experience zone to allow the visitors to see OLED TV and LCD TV at once. This direct comparison exhibition with OLED and LCD is the 2nd one after one in WIS 2015. In this exhibition in IMID Exhibition 2015, LG Electronics presented their new 2015 release 55inch UHD LCD TV and 55inch UHD OLED TV. This is considered a reflection of LG Electronics’ determination to target the market through OLED TV rather than LCD TV.

 

LCD TV is illuminated through BLU and therefore difficult to achieve perfect black. Through IMID Exhibition 2015’s comparison experience zone, LG Electronics emphasized OLED TV’s merits such as perfect black, perfect viewing angle, and ultra slim design.

 

Since the release of OLED TV, LG Electronics continued presentations that emphasized OLED TV’s advantages in diverse exhibitions. However, recently they are pursuing aggressive promotion focusing on OLED even exhibiting comparison against their own latest LCD TV. On the other hand, their rival Samsung Electronics is maintaining their 2-track strategy of using OLED and LCD in different applications each. The industry is focused on how these development will affect the large area TV market.

[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.

OLED TV, Pay Attention to China and UHD

IFA 2015 that opened on September 4, closed its curtains on 9. This year’s IFA was similar to IFA 2014 in terms of diverse OLED TV exhibition, but when analyzed in detail there were several differences.

 

First, the emphasis on UHD TV greatly increased. The percentage of UHD resolution of exhibited OLED TV was approximately 71% in IFA 2013, and 70% in IFA 2014. However, in IFA 2015, the percentage increased to approximately 92%. If the main theme for IFA 2014 was curved OLED TV products, UHD was the keyword for IFA 2015.

 

Another important factor is increasing participation by Chinese companies. In IFA 2013, only Haier exhibited OLED TV but this increased to 2 companies, Changhong and TCL, in IFA 2014. In IFA 2015, 3 companies, Haier, Changhong, and Skyworth, presented OLED TV. It is estimated that the OLED TV exhibition attendance by Chinese electronics companies will continue to consistently increase.

 

There is much attention on how many more Chinese companies will participate with OLED TV in IFA next year, and whether a new keyword following UHD will appear. Although IFA 2015 ended, OLED TV market continues to move.

Gear 2 has the most basic circular shape, but the rotating bezel within the simple design boasts the perfect blend of digital and analog. The rotating bezel design used in stop watch in quality sports watch was applied to add a touch of analog. At the same time, the smartwatch has the digital side from the jog dial used in quality vehicles, merging the analog with digital.

 

Smartwatches until now had to be touched to change screen. However, Gear 2’s rotating bezel allows the screens to be changed easily through dial rotation.

Gear 2 applied flexible OLED produced by Samsung Display same as Gear with its 1.2inch size and 360×360 resolution. Compared to competitors’ 1.3inch, it might feel smaller but has the highest resolution; Samsung Electronics used a smaller display with better expressiveness. Particularly, absolute black, one of the advantages of OLED, is actualized with this product. The quality of black in previous Gear fell short and the screen wallpaper showed hints of blue. The new display shows that it is of OLED leader, Samsung family, with its brilliant colors using latest OLED materials.

 

Gear 2 also uses Tizen OS and firmly differentiated itself from other products. In fact, other products employed Google OS and had a problem of basically being the same under the different exterior leading to no particular differentiation factors for the consumers.

 

However, deserving the title of the leader of the smart device, Samsung Electronics utilized independently developed Tizen and boasted totally different interior.

[IFA 2015] Panasonic OLED TV

Panasonic that used to lead Japanese electronics industry with Sony is focusing more on OLED TV industry. Until IFA 2014, Panasonic exhibited self-made OLED TV using oxide TFT and solution process OLED technology. However, since CES 2015 Panasonic presented LG Display’s WRGB OLED panel applied OLED TV. It is unusual to introduce OLED TV through IFA 2015 when Panasonic is only selling TV domestically and stopped TV business abroad. According to Panasonic the company is planning to mass produce within 2015.

 

OLED TV revealed in IFA 2015 is a CZ950 model with 4K resolution. It is interesting to note that special material is used to cover the back of the set to give a furniture look.
