[OLED summit 2016] HDR contents- OLED TV, most suitable

/in , , , /by

Movie companies in Hollywood has begun to produce HDR contents since 2015, and recently so have media contents companies. Consequently HDR-supporting 4K TV becomes a center of attention in the market.

HDR is being applied to Samsung SUHD TV and LG OLED TV, as well as most 4KTV companies.

HDR applicability will be a daunting challenge for a premium TV.
At OLED summit 2016 LG Display proudly announced that OLED TV is the best to express HDR contents among existing TV sets in the market.

<Senior researcher Yu, SahngJin at LG Display>

Yu, SahngJin, the senior researcher at LG Display screen quality development team said, “the most critical component to express HDR is peak highlight and the most frequent peak highlight size in the HDR screen is less than 1% window size. In case of more than 1% window size, the peak brightness of QD-LCD is over 1,200nit, higher than OLED TV, however if it is reduced to 1% or less the peak brightness of QD-LCD is drastically reduced and for the 0.01% window size, approximately 100nit merely. OLED TV can express consistent peak brightness over 500nit on average in a less than 10% window size. Say HDR contents expression range is 100. QD-LCD TV is equivalent to 40 while OLED TV, 60, 20% better quality than QD-LCD to express HDR contents.” Certainly OLED TV is most suitable for HDR.

At the demonstration of OLED TV and QD-LCDTV, OLED TV stressed on the best screen quality ever in the existing market with the crystal clear presentation of black and other colors plus wide visual angle-.

QD-LCDTV is also being developed to express various and rich colors on TV screen but there is a limit of non-emissive display in BLU, which therefore presumably cannot exceed LG OLED TV screen quality.

[OLED summit 2016]AMOLED panel Application, will it succeed in extension to PC?

/in /by

On the first day of OLED Summit 2016, presentations on Intel and OTI Lumionics for PC AMOLED panel were held. Both of these two companies presented on topics of current situation analysis for PC AMOLED panel and upcoming opportunities, and noted that there is a long way to go for AMOLED panel for PC.

On January 2016, Lenovo presented the introduction of world’s first OLED laptop ‘X1 Yoga’ with 14-inch 2550×1440 resolution AMOLED panel, and HP also presented the introduction of 13,3-inch 2560×1600 resolution OLED laptop ‘Specter X360 hybrid laptop/tablet’. Also in CES2016 held early this year, Samsung introduced ‘Galaxy Tab Pro S’ where they seem to prove the possibility of AMOLED panel for PC.

However, both Intel and OTI Lumionics explained AMOLED panel lacks in power consumption, brightness, lifespan, and price compared to LCD. OTI Lumionics showed the results of three products, Galaxy Tab Pro S, X1 yoga, and Mac book, emphasizing the need for improvements in AMOLED panel for PC.

Especially, OTI Lumionics CEO Michael G. Helander said, “as a result of burn-in test of AMOLED product for PC, it decreased to under LT97 in 80 hours, and it is an especially important factor for office PC which runs daily average of 7 hours. Considering that products with AMOLED panel are at premium level, it must be improved 10 times better compared to now”, emphasizing the reduction of burn-in phenomenon after the lifespan of PC AMOLED panel being improved.

Intel John F. Jacobs said “although OLED has big issues in lifespan and power consumption in white environment, the recent trend of PC tend to utilize contents with various color compared to existing office or internet-based white environment where the white background tend to decrease. It can be a new opportunity for OLED”, emphasizing the opportunity of OLED.
In order for white realization, AMOLED panel must drive all sub pixel of RGB. So in regular PC environment where white background is normally used such as office program or internet browser, AMOLED panel is mainly applied in special monitors such as medical and broadcasting due to issues of increasing power consumption and comparatively decreasing lifespan.

However, as Intel presented, considering that the PC environment is gradually changing and the lifespan of OLED is continuously improving, it is expected that AMOLED panel will have a bright future with PC as well.

While emphasizing high contrast range, fast response speed, wide viewing angle which are the strength of OLED, it is analyzed that the development of OLED luminescent material must be the main point in extending the OLED industry.

In OLED Summit 2016 being held in San Diego, USA, LG Display compared similar level of highest model 65-inch LG UHD OLED TV and 65-inch Curved QD-LCD TV, which it attracted many participants’ attention.

The specification of comparing models are as follow.

It presented in a way to compare various picture qualities of OLED TV and QD-LCD TV through various films and patterns such as normal TV program and movies.

LG Display personnel said, “OLED TV absolutely expresses black better than QD-LCD TV if OLED TV and QD-LCD TV set the mode that expresses white color 6500K which is the standard of UHD Alliance. Basically, the brightness of QD LCD TV is higher than OLED TV, but because the basis is LCD, it feels more distortion because of more white tone compared to the color of OLED TV. Also, OLED TV can almost express without distortion even in viewing angle, but the color is distorted in QD-LCD”, emphasizing better quality of OLED TV than QD-LCD TV.

< Comparisons of 65inch OLED TV(Left) and 65inch curved QD-LCD TV’s Black Expressiveness >

Comparing the two pictures similar to images of space show below at the exhibition, OLED TV shows individual stars accurately while QD-LCD TV presents the stars vaguely just to indicate them. In the aspects of viewing angle, OLED TV nearly didn’t have any left-right color changes but its changes were found in QD-LCD TV.

Previous SID2016’s Nanosis and QD vision, Samsung and Hisense emphasized that QD-LCD is better than OLED TV in IFA 2016, but in this OLED Summit 2016, LG Display showed that OLED TV is much more outstanding compared to QD-LCD TV.

Like this, the position between QD-LCD TV and OLED TV is becoming more competitive, and the industry has the interest in which type of TV will gain more of customer’s trust.
