If the Galaxy S Series luminance increase trend continues, it is estimated that the luminance will reach 754 nits within 2-3 years. In order to produce Galaxy S with 754 nits, the luminance of blue emitting materials, that will be used for the product’s AMOLED, is analyzed to require improvement by approx. 3.7 times.

According to AMOLED Characteristics Analysis Report of Galaxy S Series, published by UBI Research, the analysis of luminance increase trend of Galaxy products from S4 released in 2013 shows Galaxy S series with full white luminance of 430 nits and peak white of 754 nits is expected to be produced within 2-3 years. The Galaxy S4 luminance is 338 nits (peak white), and the luminance increased to S7’s 505 nits via S5 and S6’s 400 nits mark. Calculating based on this trend, the future product is analyzed to have 754 nits of luminance.

The report reveals that for Galaxy S7, the luminance of red materials is 142 nits, green 338 nits, and blue 26 nits. To actualize 754 nits screen, the red materials have to improve luminance by approximately 1.5 times, green 1.2 times, and blue 3.7 times. UBI Research explained that for high resolution screen with limited size, emitting materials performance improvement is a must and that technology development should be focused on blue emitting materials.

An article by Barry Young, the managing director of the OLED Association, in Display Daily created much excitement in Korean display industry when domestic media picked up the story on 14 June. The article includes Young’s suggestion, “don’t believe the garbage about QLEDs in 2019”.

Clarifying this comment, experts unpack this to mean Young’s pessimistic outlook for QLED mass production in 2019 forecast rather than for QLED itself.

Barry Young discussed QD in an article titled Drinking the QD Kool-Aid in Display Daily. It is estimated that the comment is aimed at the recent speculation that Samsung Electronics will mass produce QLED TV as the next generation product in 2019 rather than OLED TV. While Samsung Electronics has not announced their official position regarding QLED TV mass production timing, some sectors within the market believe it will be possible by 2019. However, many have differing opinions.

QLED is a display that uses quantum dot for emitting layers’ host and dopant while maintaining the common layers used in the existing OLED. Quantum dot, emitting layer materials used in QLED, utilizes inorganic materials and can lower the production cost in comparison to OLED’s emitting layer materials. That the process does not require evaporation as it can be carried out through ink jet printing is another advantage, and some also believe that QLED color purity is superior to OLED.

Despite these, some experts point out that it is difficult for QLED to become the main force of the premium TV market, surpassing OLED, in a short time. QLED has to solve several technological issues including lifetime and emitting efficiency. When mass producing QLED, pin holes occur and reduce device lifetime, and as the hole and electron are not balanced the emitting efficiency falls. Furthermore, as even research has not been carried out regarding QLED lifetime and degradation, whether it will be commercialized by 2019 is also in question.

Meanwhile, Young refuted the argument that QD-LCD’s picture quality is superior to OLED. He proclaimed that QD Vision and Nanosys are making “very questionable statements” about how “OLED TVs were outperformed by LCD’s with QD enhanced LED backlights” without considering merits of OLED such as contrast ratio, viewing angle, response time, color accuracy, and form factor as well as luminance and color area.

With diverse merits, OLED application is increasing to include notebook, tablet, monitor, etc. Accordingly, Samsung Display’s OLED panel is being actively expanding to this market.

HP recently began shipping Spectre 360, a notebook equipped with Samsung Display’s 13.3 inch OLED with resolution of 2560 x 1600. Previously, in CES 2016 (6-9 Jan) Samsung Electronics revealed Samsung Display’s 12 inch OLED equipped Galaxy Tab Pro S, and HP and Dell also presented Samsung Display’s 13 inch mark OLED equipped labtop.

In SID 2016 (22-27 May), Samsung Display presented 2560 x 1440 resolution 13.3 inch and 14 inch OLED for notebook and actively targeted the notebook market. Following this, a Korean press reported that Samsung Display will stop production of TN panel, low resolution LCD panel for notebook and monitor. That Samsung Display is actively targeting the notebook market is analyzed to be a strategy to create premium market advocating diverse advantages of OLED.

Due to superior contrast ratio, OLED’s picture quality is clearer in comparison to LCD, and easy to create premium market as the weight can be lighter than LCD. Burn in effect, considered one of OLED’s drawbacks, is also known to have been much improved.

As the price of OLED is higher than LCD at present, specialist market, such as medical, should be targeted first. However, when the price competitiveness improves in future, popularization of OLED is anticipated. Accordingly, Samsung Display is actively taking action in notebook and tablet OLED market expansion. UBI Research reported that 2016 Q1 OLED panel shipment for tablet increased by more than 10 times compared to the same period in 2015.

According to UBI Research’s 2016 OLED Display Annual Report, the 11 inch – 13 inch, notebook and monitor use, OLED panel shipment is expected to record 100,000 units this year, and this is expected to increase by 10 times in 2020.

Samsung Display’s recently revealed 5.5 inch 806 ppi AMOLED is expected to contribute to the expansion of the global VR (virtual reality) market as well as providing synergy for both Samsung Electronics’ future VR and smartphone business.

In SID 2016 (22-27 May), Samsung Display revealed 5.5 inch AMOLED with resolution of 806 ppi. This 4K UHD display has the highest resolution for 5 inch mark AMOLED in industry.

The response speed of AMOLED is approximately 1,000 times faster than LCD and can actualize much superior picture quality due to exceptional contrast ratio. The reduced amount of harmful blue light is also another merit of AMOLED, and it is becoming the general trend for display for VR display.

Even at the same resolution, the visual effects for smartphone and VR device are different. For example, 577 ppi QHD resolution applied to Galaxy S7 can actualize quite clear picture quality for smartphone. However, when the display is directly in front of the eyes, in cases of VR, aliasing effects, when what is on the screen looks jagged, occurs. In order to produce clear picture quality with almost no aliasing effects in VR, expert believe that 1,500 ppi is required at minimum. However, the current VR AMOLED only can actualize up to high 500 mark ppi.

That Samsung Display displayed AMOLED with resolution of over 800 ppi for the first time should be noted. With this resolution, aliasing in VR can be significantly improved even if not perfectly. Furthermore, this AMOLED has the same brightness as the Samsung’s Galaxy S7. Considering the production yield improvement, this display could be used for Galaxy S8 (TBA) that is expected to be released in 2017. For VR device connected to smartphone, smartphone’s resolution is directly related to the VR’s picture quality. This means that the Samsung’s 806 ppi 5.5 inch AMOLED allows for UHD smartphone production as well as the introduction of VR with upgraded picture quality.

UBI Research explained that while some believe that ultra-high resolution is not necessary in small screen such as smartphone, the 4K UHD 5.5 inch AMOLED is significant in that smartphone is linked with VR which market is being opened. He added that the 806 ppi AMOLED recently revealed in SID 2016 by Samsung will contribute to the expansion of the global VR market as well as providing synergy for both Samsung Electronics’ future VR and smartphone business.

Of the new OLED display equipped products released in Q1 2016, smartphone and wearable products significantly increased compared to the same period in 2015. However, for OLED TV sector, no news was reported in Q1 other than LG Electronics’ new product.

According to UBI Research, 17 new OLED equipped smartphones were released in Q1 2016. This is 4 more than Q4 2015, and 12 more than Q1 2015. Of these, Samsung Electronics released 4 smartphones including Galaxy S7 and S7 Edge, responsible for the largest proportion. Following Samsung, ZTE, Gionee, Acer, and BLU each launched 2 OLED smartphones, and Vivo, HiSense, Konka, HP, and Microsoft released 1 each. Of the companies, 6 are from Greater China Region.

For OLED equipped wearable new products, 7 were released in Q1, 2 more than Q4 2015, and 4 more than Q1 2015. Sony, Oculus, HTC, and Sulon released new VR products. Epson released smartglasses, and Fitbit and Intex released smartbands. OLED wearable market showed much activity in Q2 2014 with over 20 new products centering around smartwatch and smartband products, which quietened down since then. However, with recent new releases of VR and smartband devices, the market is being rejuvenated.

LG is still dominating the OLED TV market. LG Electronics was the only company to release new OLED TV in Q1, and released 4 products in 55 inch – 77 inch. The market showed some movement in Q1 2016 when several Chinese companies, including Haier and Changhong, released OLED TV. However, since then the market, except for LG, has been quiet. This is analyzed to be due to high price of large area OLED panel, panel supply shortage, etc. In Q2, China’s Skyworth released a new product but the sales are known to be less than anticipated.

One expert explained that large area OLED still have issues that need to be solved compared to small OLED including price competitiveness. He added that latecomers such as Chinese companies are slow to select OLED for TV compared to smartphone.

Recently, DigiTimes reported that Chinese smartphone companies are discussing supply with Taiwanese panel companies due to panel shortage. According to the report, executives of Chinese smartphone companies such as ZTE, Vivo, GiONEE, etc. and Chinese panel companies including Truly recently met with Taiwanese panel companies, AUO, Innolux, Chunghwa Pictures Tubes, etc.

The reason that Chinese smartphone companies are experiencing the panel shortage is known to be because their panel suppliers reduced smartphone panel production due to too low prices. However, DigiTimes reported that Huawei is receiving relatively sufficient amount of panels from BOE, Tianma, etc.

Meanwhile, Skyworth, one of key Chinese OLED TV selling companies, showed lower than anticipated OLED TV sales in financial year of 2015 which ended in March. Chinese media reported that this is due to insufficient supply of OLED panel from LG Display.

CTO of  JDI , Hiroyuki Ohshima, estimated that the display will evolve to flexible and human friendly, and emphasized that LCD is not suitable for flexible

During his keynote session in SID 2016 (22-27 May), Ohshima discussed the future of display. He explained that the display will evolve to System Integrated Display that combines different technologies and toward flexible.

Display is expected to become more interactive with human body. Beyond touching the screen with fingers, biological signals will be recognized such as heartbeat, eye gaze, fingerprint, and palm print. Through these, display will evolve into an input device that moves deeper into people’s lives.

For these to become a reality, Ohshima explained that diverse technologies such as touch, recognition, security, health care function, pen input need to be applied to the display. He stressed that display is heading toward flexible and noted LCD’s limitation regarding this issue.

Ohshima told the attendees that as LCD requires backlight and glass substrate is used, it is not suitable to actualize flexible panel. For OLED, it is expected to move forward to flexible and foldable exceeding ultra-thin and curved. However, he added that OLED still has several issues that need to solved including not being able to follow LCD in terms of pixel density.
