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.

Barry Young Suggested “Don`t Believe the Garbage about QLED in 2019” (Source = Samsung)

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.

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.

A forecast that Apple will apply more OLED than Samsung Electronics from 2021 has been suggested.

On 13 May, UBI Research hosted OLED Investment Analysis Seminar titled The Effects that Apple will have on Display Industry in Seoul, Korea. At this event, UBI Research’s Choong Hoon Yi estimated future flexible OLED smartphone market share.

According to Yi, Apple is to begin releasing flexible OLED iPhone from 2017, and occupy 8% of the global flexible OLED smartphone market in that year. Following this, Yi analyzed that Apple will continue to increase market share each year to record 32% in 2020, same as Samsung Elec., and exceed Samsung Elec.’s 27% with 37% in 2021.

For 2015 and 2016, with the market share of over 70% of the global flexible OLED smartphone market, Samsung Elec. is dominating the market. However, Apple is expected to release OLED iPhone from next year, and iPhone market share is increasing within the smartphone market. Yi believes that Apple’s OLED usage will exceed that of Samsung Elec.’s.

UBI Research estimates that the smartphone market will grow at CAGR of 6% in 2016-2021, and overall shipment will increase. Of these, Samsung Elec. has been outdistancing Apple and greatly increasing the market share until 2013. However, since 2014, Samsung Elec.’s market share has been gradually decreasing while Apple’s is increasing.

At the seminar, Yi told the attendees that Apple is selling approximately 220 million units of iPhone per year, but the number is expected to increase to 300-million-unit mark and of 30% of that, 1,00-million-unit mark, are estimated to be OLED equipped products. He added that this will grow to 4,00-million-unit mark in 2020, and 80% of that is estimated to be OLED.

With Apple’s section of OLED, the competition for the product supply between global display companies is expected to be fierce. Yi forecast that Samsung Display will supply 60% of the demand, the second supplier 30%, and the rest 10%.

LG Display and Japan Display were likely to be the second and third suppliers. However, Apple’s steadfast partner, Foxconn took over Sharp and became a strong candidate for this position. Hence, 4 companies could end up supplying to Apple. Yi added that one company of JDI and Foxconn could be pushed out.

Panel companies’ mass production establishment investment for product supply for Apple is also being carried out. Samsung Display is expected to execute 45-60K investment in flexible AMOLED line this year. LG Display is carrying out Gen6 7.5K investment in Gumi, with prospect of additional 7.5K order this year.

JDI also announced smartphone AMOLED panel mass production in January 2016 aiming for mass production in 2018. There is a possibility of investment for AMOLED supply for iPhone. Yi also estimated that Apple will conclude OLED emitting materials company selection by this August or September.

Furthermore, Yi explained that a human eye is more sensitive to contrast compared to brightness. He emphasized that OLED, with its contrast ratio of 1,000,000:1 is a more human friendly display than LCD and its 3,000:1.

At the seminar, LG Economic Research Institute’s Senior Consultant Wookeun Lee also analyzed the market with the theme of The Effects that Apple’s OLED Selection will have on Korea and China’s Display Industry.

Following Foxconn’s takeover of Sharp, which company will end up suffering the most?

On March 30, Taiwan’s Hon Hai’s Foxconn agreed to buy Sharp for about $ 3.5 billion. With this decision, there is much focus on how it will affect the global display market.

 

Korean companies leading the global display market such as Samsung Display and LG Display as well as key display companies in Japan, China, and Taiwan are keenly interested in this takeover.

 

Some experts analyze that, out of these companies, the one being most threatened by this takeover will be Japan Display.

 

◆ Japan Display, May Not be Able to Retain OLED Supply for iPhone

 

As it became known that iPhone will replace the LCD panel with OLED for future iPhone, it is expected to create a great business within the OLED market. 3 companies, Samsung Display, LG Display, and Japan Display, have been considered as the most likely supplier for iPhone’s OLED panel.

 

Some media have reported that Samsung Display and Apple have already signed OLED supply agreement, and LG Display and Japan Display are known to be having a heated competition to become the secondary supplier.

 

However, this Foxconn’s takeover of Sharp could break the big 3. Of these, experts estimate that Japan Display is most likely to be pushed out.

 

iPhone’s largest LCD panel supplier is LG Display, with over 50%. Following this, Samsung Display and Japan’s Sharp are the second and third LCD panel supplier for iPhone but the order has not been confirmed.

 

As it became known that Apple will utilize OLED, Japan Display with investment plans for OLED mass production line rose as the possible panel supplier for Apple. Rather than Sharp, Japan Display became a strong candidate for OLED supplier for iPhone along with Samsung Display and LG Display.

 

However, it all changed when Foxconn bought Sharp. Sharp does not have OLED line for mobile device at the moment, but its small device LCD line is LTPS based that could be transformed to OLED. Foxconn, expected to invest in OLED sector, is likely to turn Sharp’s small device LCD line into OLED line.

 

Furthermore, Foxconn is Apple’s key production collaborator. Worse, even Foxconn’s newly bought Sharp is one of Apple’s panel suppliers. Excluding Samsung Display and LG Display with verified OLED technology prowess, Apple could choose Foxconn with closer connections rather than Japan Display as an OLED supplier.

 

One display industry expert explained that Foxconn could push out Japan Display regarding iPhone OLED supplier issue, and even if that does not happen, it will have very narrow standing. He added that although compared to Samsung Display and LG Display, Foxconn and Japan Display are both latecomers in OLED sector, Foxconn is in a more favorable position due to its solid relationship with Apple.

Why is ‘Cadmium-free’ Significant? Samsung’s Quantum Dot SUHD TV

/0 コメント/カテゴリ: , , /作成者:

Hyunjoo Kang / jjoo@olednet.com

On the subject of Samsung Electronics’ 2nd generation quantum dot display equipped SUHD TV product, recently released in Korea, display experts consider the actualization of 1,000 nit without cadmium as the key strength.

 

In 2015, Samsung Elec. first launched quantum dot SUHD TV under the name nanocrystal technology. Each quantum dot of nanosize, 10,000 times narrower than a human hair, actualizes accurate color.

 

According to Samsung Elec., the 2nd generation quantum dot technology to produce this new product, an improvement over last year’s. The company emphasized that compared to the previous product, the price was reduced and brightness was improved. HDR (high dynamic range) with 1,000 nit maximum was applied to the new product.

 

The 1,000 nit brightness is the standard figure of premium image produced in Hollywood, US. If this figure is high, screen’s bright and dark areas can be experienced fully even in bright environment such as a living room area.

 

Although not applied to all models of Samsung’s 1st generation quantum dot SUHD TV, 1,000 nit brightness was applied to the majority of the models; that 1,000 nit brightness was applied to the new product is not worth much attention by itself.

 

<Samsung Elec.’s 1st Generation Quantum Dot TV vs. Other Display in CES 2015>

 

◆Hazardous Heavy Metal Cadmium, Why Difficult to Remove?

 

Quantum dot film includes cadmium. As cadmium is a hazardous heavy metal, cadmium including quantum dot film cannot be environmentally friendly. Cadmium use in Europe is limited.

 

However, without cadmium, the quantum dot film’s optical efficiency is reduced. In order to make up for this, LED chips have to be applied which increases the price as well as the energy consumption. An alternative method to avoid this is development of additional quantum dot materials that increase efficiency.

 

For these reasons, some Chinese companies that produce quantum dot display equipped products select to use cadmium, overlooking the environmental issues. Samsung Elec. also emphasized that it is the only company that utilizes environmentally friendly cadmium-free quantum dot materials.

 

Through quantum dot materials’ efficiency and color mapping algorithm improvement, Samsung actualized 1,000 nit brightness without resorting to cadmium and without increase in power consumption. Color accuracy, which is a quantum dot display trait, was also improved by 25%.

 

Samsung Elec. is planning to release 14 models of SUHD TV, from 49 inch to 88 inch, in Korea. This is over 30% increase compared to last year. The price also was reduced by 900,000 KRW compared to the previous version. The new products, depending on the specifications, cost around 6 million KRW for 65 inch, and 4 million KRW for 55 inch.

A comment from a display expert is, “the new product has 1,000 nit brightness is not significant by itself, and color accuracy improvement also is not of much attention as it is an existing quantum dot trait”. However, he also put another comment from his analysis, “1,000 nit brightness was actualized without using cadmium and without decreasing energy efficiency is worth noting”.
