May 10, 2012 — Organic light-emitting diodes (OLEDs) emerged on the display scene recently, gaining adopters in small screen sizes like smartphones, and just moving into large-size displays like 55” televisions in recent months (LG Electronics made one in December 2011; Samsung Electronics came out with one at CES in January 2012). OLED offers better power consumption, light emission, and clarity than liquid crystal displays (LCDs)

As OLED adoption ramps up, mass production technology for large-area OLED is increasingly an issue that could prohibit OLED from gaining market share on LCD. In current OLED manufacturing, color patterning is achieved by fine metal mask (FMM) using thermal evaporation, and laser-induced thermal imaging (LITI), which can be limited to small-size panels. Manufacturers are now looking for color patterning technologies — from solution-based printing to laser imaging and layering white OLEDs with filters — that suit display production at Gen-8 fabs or larger.

Samsung Mobile Display (SMD) is developing small mask scanning (SMS) technology, which improves FMM color patterning. Hybrid patterning system (HPS) technology combines LITI and FMM, and is currently under development. LG is working on a method that combines white OLEDs with color filters (WOLED+C/F).

Displaybank issued a Korean patent analysis report regarding the OLED color patterning technology, comprising research and analysis about the patents of foreign companies in Korea as well as the key patents of Korea-based companies. 495 patents relating to OLED color patterning technology were selected in the primary screening among a total of 2,532 raw data disclosed or registered by December 2011. 52 key patents regarding SMS, HPS, Ink-jet, and WOLED+C/F technology were then analyzed as large-area OLED color patterning technologies.

May 10, 2012 — Global TV shipments will remain flat in 2012, for the second year in a row. Shipments to developed markets, especially Western Europe and Japan, will fall 11% year to year (Y/Y), offset by 8% growth Y/Y in emerging markets, according to the NPD DisplaySearch Quarterly Advanced Global TV Shipment and Forecast Report.

The liquid crystal display (LCD) TV market will continue to grow, capturing market share from declining cathode ray tube (CRT) and plasma technologies. Consumers in saturated markets are cautious, making them sensitive to price differences. “LCD is expected to continue narrowing the price gap with plasma,” noted Paul Gagnon, director of North America TV Research for NPD DisplaySearch. Many TV brands are “focusing on profits over volume,” Gagnon added, suppressing the rate of price erosion compared to recent years. This too could impact demand.

Larger panels sizes continue to increase share, lifting the average size of TVs shipped to almost 35” in 2012, up from less than 30” four years ago. The growing number of larger display factories used to produce LCD TV panels has helped the average area price to fall rapidly. In developed markets, this encourages existing flat panel TV households to trade up to a larger size, driving a new replacement wave. It also lowers barriers to first-time adoption in emerging markets converting from CRT TVs.

LCD TVs are expected to account for more than 88.5% of total TV shipments worldwide in 2012, up from 82.5% in 2011. LCD TV shipments will grow 7% to 220M in 2012, and rise to 241M in 2013. Expect LCD TVs to hold >90% market share in 2013.

Plasma TVs will account for just 5.3% of shipment volume in 2012, down from its peak at about 7.4% in 2010. Plasma TV shipments will fall 24% in 2012 to 13.1M, dropping to less than 3M by 2015.

The newest flat panel TV technology, organic light-emitting diode (OLED), will debut in large sizes in 2012, but volume will be very small, starting with 50,000 or fewer units.

The share of LED-backlight LCD TVs will increase to 70.1% in 2012, up from 45.3% in 2011, thanks to new low-cost direct-LED backlight models challenging CCFL-backlit models. http://www.electroiq.com/articles/sst/2012/05/lower-cost-led-backlights-darken-ccfl-future.htmlWhile bulkier than LED-edge-lit models, lower-cost direct-LED LCD TVs will attract the most price-sensitive consumers. Even so, 5 times as many edge-lit LED backlight LCD TV will be shipped than direct-lit models, and the premiums for edge-lit LED LCD TVs are expected to start falling faster later in the year.

3D TV had a soft start in North America, but is experiencing a surge in popularity elsewhere, with shipments of more than 24M units in 2011 and an anticipated 90% increase in 2012 to 46M units. Shipment penetration is expected to exceed 25% in both Western Europe and China and 20% in Eastern Europe. While North America is still expected to lag with 19% penetration in 2012, it should be the leading 3D shipment region by 2014, when most large screen sizes will include 3D capability as a standard feature; North America will be the top region for 40”+ TV shipments.

China became the largest overall TV market in 2009 and the largest LCD TV market in 2011. However, with household flat panel TV penetration reaching high levels in urban areas, growth is expected to slow until rural cities start seeing increased adoption. LCD TV shipments are forecast to grow 11% Y/Y in China during 2012, down from 17% Y/Y growth in 2011. Some of the first evidence of this slowdown was seen in recent May Day holiday sales results in China. According to Bing Zhang, Research Director in the China Market for NPD DisplaySearch, “Analysis of sales during the recent May Day holidays in China indicates that sell-through was below expectations with low- to mid-single-digit growth and slightly elevated inventories after the end of the holiday.”

The DisplaySearch Q1’12 Quarterly Advanced Global TV Shipment and Forecast Report, available now, includes panel and TV shipments by region and by size for nearly 60 brands, and also includes rolling 16-quarter forecasts, TV cost/price forecasts, and design wins.

May 7, 2012 — Low-cost direct light-emitting diode (LED)-backlit liquid crystal display (LCD) TVs were introduced in March 2011, targeting share in the entry/mainstream LCD TV market currently dominated by cold-cathode fluorescent lamp (CCFL)-backlit TVs.

Samsung Electronics has launched its first direct LED-backlit TVs, the EH series, in the US, and LG Electronics will follow soon with its LS3400 series.

Also read: Cheaper LED backlights require LED, plate materials changes

LED-backlight penetration in the LCD TV market has been lower than expected, especially in the entry/mainstream segment: 9 points lower than DisplaySearch’s 2011 forecast overall. LED technology for backlights was more expensive than anticipated, limiting consumer purchases. Edge backlight designs were not able to meaningfully reduce the cost premium over CCFL backlighting, though the concept has helped TV makers maintain revenues against a severe market overall.

Figure 1. Trends for LED-Backlit TV Price Premium and Penetration. SOURCE: Q1’12 Quarterly LED Backlight Report.

Now, TV makers are focusing on new types of direct LED backlighting to capture a broader swath of consumers, adding value to the entry/mainstream segment just as edge LED backlighting added value to the premium segment TVs. At the same time, the CCFL industry is experiencing shortages in rare earth metals, stressing already-tight cost structures. There are fewer new CCFL-backlit models this year. DisplaySearch expects the price premium for direct LED-backlit TVs over CCFL-backlit TVs to decrease quickly.

In the Q1’12 Quarterly LED Backlight Report, DisplaySearch forecast that LED backlighting, with help of low-cost direct designs, will achieve 100% penetration of the LCD TV application by the end of 2014, killing CCFL designs. Low-cost direct LED backlighting (~20% share in 2014) will take share away from CCFL backlighting, not from edge LED backlighting. At the same time, edge LED backlighting will continue to incrementally replace CCFL backlighting. Low-cost direct LED backlighting will saturate after CCFL-backlit TVs leave the market and maintain its market position in the entry/mainstream segment.

Figure 2. Forecast for TV Panel Shipments by Backlight Type. SOURCE: Q1’12 Quarterly LED Backlight Report

These changes to the TV market will affect the market for CCFL in other displays, such as monitors. In Q1’12, revenue from CCFL for TVs is estimated to be 81% of total CCFL revenue, as reported in the Q1’12 Quarterly LED Backlight Report. It is not an exaggeration to say that the current CCFL supply chain depends solely on the shipments of TVs. If demand for CCFL in TVs disappears, then it will be hard for the CCFL industry to maintain its supply chain, because the other applications account for only 19% of total demand. Therefore, we forecast that after CCFL-backlit TVs leave the market, most CCFL-backlit monitors will face EOL as well.

May 3, 2012 — Tablet PC shipments are expected to grow from 81.6 million units in 2011 to 424.9 million units by 2017, according to NPD DisplaySearch, overtaking notebook PCs. This rapid growth comes with diversification, in hardware like displays and in software like operating systems (OS).

Component manufacturing capacity is being increased to meet this new market demand. Many display manufacturers are transitioning tablet panel production to larger plants, including Gen 6 and Gen 8, which will lead to greater capacity for tablet displays, as well as lower prices. In addition, the share of AMOLED displays in tablets is forecast to increase from 3% in 2012 to 30% by 2017.

The young market has been “dominated” by Apple’s iPad and similarly configured tablets from competitors, said Richard Shim, NPD DisplaySearch senior analyst.

NPD DisplaySearch expects retailers, brands, and consumers to experiment with emerging tablet opportunities. Increased investments in the tablet supply chain — amidst a lull in the growth of other device categories — will lead to more opportunities for new technologies to challenge incumbents. A key area where there is room for differentiation is operating systems, with Android taking share from iOS. Windows RT will also grow, but from a very small base.

NPD DisplaySearch’s Tablet Quarterly report tracks quarterly changes in tablet PC products and strategies, and forecasts the impact of those changes on the market. It covers the changing landscape of screen sizes, features that are expected to be included and excluded in future tablets, and operating systems.

May 3, 2012 — The top 3 large-area LCD polarizer makers — LG Chem, Nitto Denko, and Sumitomo Chemical — are widening their market share (area basis) lead over other makers, achieving 77% market share in 2011, according to Displaybank’s Polarizer Market and Industry Trend Analysis report. Displaybank is now part of IHS. This 3-leader market dynamic will continue for some time, Displaybank reports.

LG Chem held the top ranking, with 27.4% market share. This is down from LG Chem’s 30.7% market share in 2010. Nitto Denko had 25.9% market share in 2011 (27.3% in 2010); Sumitomo Chem. held 23.6% (22.5% in 2010).

Figure. Large-area TFT-LCD polarizer market share by maker (area basis) in 2011. SOURCE: Displaybank “Polarizer Market and Industry Trend Analysis.”

LG Chem has a stable customer in LG Display, and benefits from high TV and monitor polarizer demand. LG Chem has entered the 3D film-patterned retarder (FPR) market, pulling from its polarizer expertise and exclusively supplying more than 98% of the global FPR market. The company is beating out DNP of Japan for FPR business.

Nitto Denko and Sumitomo Chemical both increased tablet PC and smartphone polarizer segments in 2011, and are focusing on developing and supplying AMOLED TV polarizer.

Polarizer prices fell in 2011, with TV polarizer costs especially dropping 1-2% from 2010 levels. Sluggish demand from Europe and North America contributed to the price decline.

Displaybank forecasts that 2012 large-area TFT-LCD polarizer demand area will hit 317.6 million square meters, increasing by 5% year to year (Y/Y). However, prices will fall 5% Y/Y, making the revenue forecast $7.642 billion.

May 1, 2012 — LCD panel shipments to Chinese TV makers peaked in December 2011, fell sharply in January 2012, and recovered in February, shows the NPD DisplaySearch MarketWise-LCD Industry Dynamics report. In February, shipments to Chinese TV makers from DisplaySearch’s surveyed panel makers reached 3.75 million units, up 18% month over month (M/M).

Panel shipments to Chinese TV makers are estimated to have grown seasonally 24% in March and 2% in April, affected by May Day holidays. In April, the supply chain’s production and inventory build-up is expected to have stopped. Chinese TV makers’ demand for panels will therefore fall 13% and 8% M/M in May and June, respectively.

Supply constraints were caused by low yields on new models, and adoption of new production technology at panel makers, not recovering demand in the market. Panel makers also rearranged panel capacity, and TV makers asked them to build production for new models.

There is little margin for price declines, according to TV makers, with some reporting that panel prices have reached bottom. April is expected to show a price hike for TV panels, depending on price negotiations, and interactions between Chinese TV makers and leading TV makers with their captive panel suppliers.

Figure. LCD TV panel shipment to China TV makers (millions). SOURCE: NPD DisplaySearch MarketWise-LCD Industry Dynamics.

Chinese TV brands have been cautious about building up production or stocking more panels, keeping inventory levels at about 5-6 weeks of TV sets and 7-10 days of panels on hand. Inventories have stayed at these levels even with slower domestic demand during the last two months. Most Chinese TV makers surveyed by DisplaySearch believe they can get the display panels they need from suppliers, excepting 42” and 47” and certain other models that are forecast to have supply constraints in April.

The latest industry survey shows that some panel makers have further lowered their shipment plans for Q2’12 more than once. Shipment plans for March were up a modest 2%, but DisplaySearch sees them decreasing by 1-3% in April and May. Panel makers also need to reduce their shipment plans to better react to soft demand and avoid inventory problems. This industry-wide adjustment helps stabilize supply and demand throughout the forecast months.

The two major Korean panel makers reduced their shipment targets for April and May, expressing concern about overall demand in China. This is in contrast to the forecast changes at Taiwanese panel makers. There may be fewer subsidy programs this year, and the home appliance to rural program will be the only one left in China. The decreased forecast is also a result of competition and the Korean panel makers’ business strategies (e.g. open cells) involving Chinese TV makers.

Chimei Innolux will continue to lead in panel shipments, and has significantly increased its shipment forecast for the next 3 months. Despite its increased targets, Chimei Innolux shows a clear seasonal trend in the Chinese market. Their shipments grew 30% M/M in February, and they are estimated to have peaked in March with a 24% M/M increase. Chimei Innolux will maintain this high level of shipments in April before seeing declines of 20% and 17% M/M in May and June, respectively.

LG Display does not have a positive view of Chinese demand and expressed concern that inventory might become an issue in Q2 2012. LG Display’s Q2 2012 shipment plan for China is conservative, and the company is not supporting an open-cell business for its external TV customers. At the same time, LG Display faces competitive pressures from Taiwanese panel makers on the new sizes: 29”, 39”, and 50”.

Samsung increased its TV panel shipments slightly in March. The company forecast that monthly shipments would trend downward in Q2 2012. It is projecting a low forecast for shipments to the Chinese market, especially in June. The target for June shipments is even lower than the record low that occurred in January. DisplaySearch’s industry checks revealed that TCL, Samsung’s major Chinese local TV customer, will reduce its panel procurement to support CSOT, its captive panel vendor. Despite the risk of losing some business from Chinese TV customers, Samsung expects an increase of business from its captive and strategic customers in Q2 2012. Samsung may implement its aggressive business strategy as planned, sending open-cells to China this year.

AUO plans to ship more in March, but capacity constraints and yield rate issues limit AUO’s panel output. On the demand side, AUO reported that some Chinese TV customers were adjusting inventory and pushing shipments back to April.

BOE failed to meet its shipment targets for January and February, but the company still plans to increase its shipments throughout the forecast months. BOE is focusing on the supply of 32” in particular, and there is concern about a supply imbalance for 32”, especially in the Chinese TV market. Currently, more than 55% of BOE’s panel shipments are to Chinese TV makers.

There is competition from China’s local panel makers. Recently, China’s Ministry of Finance officially announced changes to the import duties on certain products, which will be effective April 1, 2012. Among them is a duty on 32”+ TV open-cells. The duty on open-cells will be increased from 3% to 5%. According to our cost analysis, the increase might not be enough to force Korean and Taiwanese panel makers to build fabs in China. However, if domestic suppliers build more LCD TV panel fabs as planned, then the import duty might be increased further. For political and business reasons, foreign panel makers are considering building LCD fabs in China. Previous plans included building fabs, but current plans include the option of moving existing fabs. An argument against building new capacity is the overcapacity in the industry.

April 30, 2012 — The global market for flat panel TVs hit a plateau in recent years, causing flat panel display (FPD) manufacturers — especially liquid crystal display (LCD) makers — to look to commercial markets such as digital signage to increase sales and profits from their large-area FPD production.

Electronic menu boards, in-classroom interactive white boards (IWB), out-of-home digital advertising and other non-consumer uses for FPDs — collectively categorized as public displays (PD) or large-format displays (LFD) — have shown solid and steady growth in recent years, rising 65% in unit volume production from 2009 to 2011.

While the PD/LFD market generally continues to rise and LCDs continue to take over for plasma, Q4’11 witnessed the first sequential decline over the last three years in the LCD portion of this market. According to the recently released NPD DisplaySearch Quarterly FPD Public Display Shipment and Forecast Report, the sequential drop in global shipments came in the least well-defined portion of this market, the 26-37” space. This is not the first sequential decline seen in the PD space, but most sequential declines in recent years have been from reduced plasma production, not from reduced LCD sales.

Figure. Worldwide FPD Commercial Public Display Shipments by Technology. SOURCE: NPD DisplaySearch Quarterly FPD Public Display Shipment and Forecast Report.

The commercial markets for larger-size FPDs remain small compared to the vast market for consumer TVs, but the complex nature of these B2B sales and the specialized nature of the displays produced specifically for these markets yield higher revenues and margins compared to commodity consumer applications.

On the surface, many of the displays used in commercial environments have similar specifications to their TV counterparts, especially in terms of size and resolution, but most are engineered for specific use in out-of-home environments. Many use more advanced materials in their design and production to meet the stringent needs of commercial installers. Such advanced materials include higher brightness backlights needed to overcome uncontrollable ambient light in open-air environments and unique liquid crystal material needed to minimize imagine sticking when static images are displayed. Others also offer advanced features such as uniform, super narrow bezels for video walls, network connectivity, interactive touch capabilities such as for white boards and even transparent capabilities.

“Commercial markets for flat panel displays, such as for digital signage, remain the jewel of the LCD industry,” noted Chris Connery, DisplaySearch Vice President of PC and Large Format Commercial Displays. “The challenge comes when trying to fully quantify these markets since many times installers use consumer-grade TVs for quick hang-and-bang solutions.”

The volume zone of the public display market still centers around the 32” category (same as the LCD TV market). The 26-39” segment, while being the largest, has also been the least defined segment of the public display sector. This market is largely filled with installations of consumer-grade TVs or with commercial-grade sets that use LCD TV panels. For this reason, many in the industry often disregard segments below 40” when trying to quantify the true market and/or its growth. While these gray areas below 40” showed a short-term downturn, quite noticeable in Q4’11 was the increased production share of very large-size displays. In particular, Sharp aggressively shipped out 70” panels to most efficiently utilize its Gen 10 capacity and to boost the interactive white board market.

“Any sequential decline in unit volume shipments into commercial sectors is hardly cause for alarm, as it may be in consumer sectors,” notes Connery “This market is more project-based, with no seasonality. For example, Burger King is rolling out electronic menu boards across the country right now. The market and major projects rolling out globally all need to be monitored regularly to confirm market success.”

April 27, 2012 — Active-matrix organic light-emitting diode (AMOLED) displays manufacturing is virtually 100% concentrated in Korea, according to Displaybank, with Samsung Mobile Display (SMD) and LG Display (LGD) scaling up capacity.

SMD began large-scale AMOLED production in 2008, and the market has expanded under SMD’s leadership, gaining adopters for smartphone displays and other 3”-4” displays.

AMOLED shipments are increasing dramatically, shows Displaybank’s report, “Korea AMOLED Light-Emitting Material Industry Analysis.” In 2011, SMD ramped a Gen-5.5 line. LGD nearly quadrupled its AMOLED production capacity since 2010, with a Gen-4.5 line coming fully on-line. In H1 2012, both companies plan to commercialize 55” AMOLED TVs. They are accelerating development with deposition equipment of 4~10K.
