G8 LG Display (NYSE: LPL) plans to increase its eight-generation LCD fabrication plant to full utilization in late May. The company just began volume production at its G8 LCD fab in March. Achieving full capacity within just two months of commencement is quite fast. FYI, LG Display’s G6.5 fab (G6 Extension) started operations in April with an initial input capacity of 15K glass substrates per month and will mostly be used to produce LCD monitor and notebook PC LCD panels.
Full Utilization LG Displays’ overall utilization in the first quarter of 2009 was 93%, which can be considered at full utilization. There is pressure to bring inventory back up to normal levels at the brand and retail levels and leading LCD suppliers have been increasing their utilization rates. LG Display’s G8 fab will mainly be used to manufacture LCD TV panels, which have experienced strong demand.
Shortage According to LG Display due to component shortage constraints such as glass the overall LCD utilization rate will range from 80 to 85 percent in the second quarter leading to about a 5 percent shortage situation. LG Display is expecting the overall LCD TV industry to achieve year over year growth in the high teens for 2009.

Make something simpler and manufacturing throughput generally increases. So does yields. With throughput and yields up, manufacturing costs generally goes down. When it comes to LCD panels the backlight unit (BLU) is the most expensive component making up about 30% of the total cost of manufacturing. Bring down the cost of the BLU and the overall cost of manufacturing LCDs come down while actually improving brightness. Not only that, because you need less CCFL tubes or LEDs power consumption is lowered as well as heat. Trivium Technologies has a product that can do just that.

Trivium is based in Cleveland, Ohio and has developed its BRILLIANT Film that improves the display’s brightness while simplifying the optical film stack of the BLU. Here is what Tom Lash, COO and co-founder of Tivium has to say about Trivium’s BRILLIANT Film and what it can do for any LCD manufacturer wanting to improve brightness, reduce complexity, power consumption, heat and manufacturing costs:
It is a safe bet that you are reading this DisplayBlog article on an LCD display, be it a desktop monitor, your notebook computer, or on your handheld device. An integral, de-facto component integrated into all of these LCD displays is a combination of optical films that enhance the display’s luminance for an improved user experience. Depending on the viewing angle requirements for the display, this stack of brightness films could include one or more diffusers to normalize the backlight’s output and mask irregularities, one or two prismatic films to boost the backlight’s efficiency, and a reflective polarizer film to further improve the display’s luminance through light recycling. Here is a simple illustration:

Starting in 2000 with angel investor funding, I and two colleagues founded Trivium Technologies to develop a novel light management thin-film for the LCD market. Our Chief Technology Officer, Dr. Neil Lubart, had conceived of some preliminary thin-film designs that included the use of compound parabolic collectors (CPC) to channel energy for differing applications, including LCD displays and concentrating photovoltaic (CPV) solar panels. Dr. Lubart’s education as an astrophysicist coupled with 30+ years in IBM’s development labs gave us a solid basis to build upon. Our CEO, Tim Wojciechowski, had a business history in materials that we also leveraged. But as we quickly learned, the road from concept to commercial-ready design can be very challenging when you are a small start-up company attempting to create an innovative technology for a global industry.
When we initially formed Trivium, we designed and filed patents for a transflective film concept that would allow the LCD display to concurrently process the backlight and any ambient light that was available to boost the display’s luminance. A successful transflective display design was considered “the Holy Grail” by display industry experts.
I published a very brief Press Release regarding our transflective film technology through an online service, and the story got quickly picked up by several online business websites and technical publications. Within a week or two, Trivium was contacted by almost 40 companies asking for information and sample transflective film for evaluation. While the enthusiasm was high and the interest in transflective technology was strong, we quickly determined that there were other key components within the display that needed much further refinement before transflective technology could be ready for commercialization. At the time, the display manufacturers were increasing their respective market share by building multi-billion dollar manufacturing plants, and they were rightly more interested in improving their current transmissive displays then experimenting with incremental transflective technology. Were we chasing the wrong target market?
Back in 2000, 3M had a tight control on the entire brightness film market. Their prismatic BEF™ film constituted over 90% of the market. 3M acquired the initial BEF™ patents from an outside inventor, and then they built a strong surrounding patent portfolio that covered the film’s design, its manufacturing techniques, etc., coupled with an aggressive defensive legal strategy to protect their market. Entering the traditional brightness film market at that time was a daunting task for any competitor.
To complement their prism film and to further grow the optical film market that they defined, 3M introduced the DBEF™ product, which is a recycling polarizer film. It provided a further boost in efficiency by recycling light from the backlight system that would otherwise be lost. By coupling the prism film with their DBEF™ product, 3M successfully raised the performance bar for the entire display industry, and kept the competitors even further at bay. In the last few years, 3M’s primary patents for the prism film have expired and several smaller companies found their opening to enter the optical film market with prismatic films that were manufactured primarily in Asia, competing on price.
Through technology evolution, some companies recently have introduced optical display films that incorporate the functionality of the diffuser layer and prism layer into one film. As display manufacturers strive for lower component cost, improved display performance, and thinner profiles, these multi-function films are an important advance for the Display industry. To reduce the cost of the brightness film stack, some display manufacturers attempted to remove the high priced DBEF™ film from the stack. They instead experimented with a combination of diffusers, prismatic films, and some of these multi-function films. As most trade-offs go, their cost was lowered, but the display’s luminance was somewhat compromised in the process.
The company’s challenge was to compete against the traditional multi-film stack of brightness films. It seemed the display industry was more amenable to incremental advances at the component level, as in this case of brightness films. They were not receptive to disruptive technologies. They wanted evolution and not revolution, especially if they could not easily integrate new components into their existing products. It became apparent to our team that the immediate market for a new brightness film was not in the experimental space of transflective displays, but in the “low hanging fruit” space of transmissive displays.
We needed to leverage our film designs and knowledge to create a brightness enhancement film that could meet or exceed the industry-standard film stack that included a diffuser film, a prism film, and 3M’s DBEF™ film. The output of these efforts is the Trivium BRILLIANT Film™.
Trivium’s design for our BRILLIANT Film™ was substantially different from the design of all of the prism films or the recycling polarizer films already in the market. We designed our multi-function film to collimate the backlight’s output, and added a reflective layer to recycle light for added efficiency. We took the functionality of multiple films and integrated them into a single-film design. Here is a simple illustration, where the film resides between the backlight and the pixel layer:

The polymer light guides in the BRILLIANT Film™ are Compound Parabolic Collectors (CPCs). These are the most highly-efficient light-guiding structures available, and are used in astronomy to capture all available photons of light. The light guides are surrounded with another polymer that has a differing Index of Refraction which allows the passing light to remain contained in the light guides, comparable to the workings of a fiber optic cable. Finally, there is a reflective surface on our film that recycles any light that does not initially pass through the CPC light guides. Within two or three reflections, the light is processed and passes through our film… collimation plus recycling in a single film design.
Trivium utilized LightTools™ software from Optical Research Associates to refine our design and to model the film’s expected performance. Through multiple design iterations, we determined that our film offered a substantial differentiating characteristic. While the prism films in the market offered a fixed light distribution because of their fixed 90° light-guiding structures, the BRILLIANT Film™ offered an adjustable light distribution based on differing CPC designs. We could tailor the film’s design for narrow distribution for your Blackberry screen with a cross-cut design, or design the film for wide-viewing angle LCD TVs by merely modifying the input and output apertures of our light guides as lenticular channels. See the two following performance graphs.
This graph shows the BRILLIANT Film’s performance in narrow viewing angle applications. The modeling data output is from Optical Research Associates’ LightTools software:

The BRILLIANT Film has cross-cut channels that guides the light through narrow angles. This is what the structure looks like:

For narrow viewing angle designs, the goal is to have all of the light processed within zero to 20 degree angles. Any light that is wider than 20 degrees in either direction is considered “lost light” for handheld applications. That is why LCD manufacturers use two pieces of BEF film (XBEF) for these applications. By crossing two pieces of prismatic BEF film, you get a cross-cut pattern. With Trivium’s narrow-angle design, the film itself has cross-cut light guides to tighten light distribution.
In a narrow-viewing angle application the typical optical film stack consists of one or two diffusers, two prism films that are crossed for narrow light distribution, and a layer of DBEF that provides a bit more efficiency. The BRILLIANT Film can be made and sold commercially for the same price point as the total cost of the combination of films in the multi-film stack. The key is that the BRILLIANT Film offers improved performance.
The following table represents the ORA modeling data, the 3M published data, and Trivium’s Prototype sample actual performance for wide viewing angle applications. The prototype was handmade and is represented by the blue line. The modeled results are based on predictive performance if manufactured to design and is represented by the green line.

The structure of the BRILLIANT Film has lenticular channels for wide angle applications such as LCD TVs:

As illustrated, the prototyped BRILLIANT Film™ exceeds the stack of Diffuser + BEF™ + DBEF™ at angles beyond 20 degrees, left to right, and substantially so from 50 degrees to 90 degrees. Think about how this could improve the viewability of your LCD TV at wider angles.
By significantly improving the efficiency of the backlight system through the use of the BRILLIANT Film, LCD manufacturers can provide the same luminance using less number of CCFL tubes or LEDs resulting in substantial reductions in cost. With less CCFLs or LEDs power consumption and heat is lowered allowing for further cost reductions.
In either wide or narrow application scenario the Trivium design outperforms the 3M stack of films. Trivium’s data modeling suggests that the BRILLIANT Film™ performance (as seen in green performance line) could benefit from further refinements to the manufacturing methods, thereby optimizing all elements of the patented design, resulting in improved performance, especially in the perpendicular luminance measurement, while simultaneously enhancing the vertical distribution to a wider viewing angle. Because our samples were “hand-made” in a non-production method, some of the necessary precision could not be obtained.
There are three basic manufacturing steps to create the Brilliant Film™, and Trivium has contracted with multiple third-party companies who have assisted in the manufacturing of our sample films. Although the prototypes to date are “hand-made” samples, they prove out the technology and demonstrate the unique means of optimizing the backlight’s output.
We have created a financial model that demonstrates that the BRILLIANT Film™ can be cost-effectively manufactured in a roll-to-roll process to compete against the total cost of the multi-stack film solutions being deployed currently. We now need a commercialization partner who can put it all together.
It has always been Trivium’s intent to find a buyer for our technology to bring the BRILLIANT Film™ to market. While small, agile technology start-ups may be best equipped to the iterative process of design, patenting, and prototyping, a more substantial company with mass-manufacturing expertise and a global marketing reach is best equipped to bring this type of technology to market.
Trivium is now working with an Investment Bank to identify one or more companies to acquire or license our IP portfolio for commercialization. All of the major LCD manufacturers have expressed a substantial interest in using new brightness film technologies that can incrementally improve the display’s performance, possibly lower costs, and improve the device’s power efficiency through enhanced luminance. The $3 Billion dollar brightness film market is open to innovation.

Shortage There is a chip on film (COF) tape shortage. COF tape is a component that is necessary to for back-end service suppliers to package LCD driver ICs. Japan-based COF tape suppliers are not likely to resume some of their production lines that were suspended during the downturn. The reason for the hesitation is that resuming production will increase manufacturing costs while the likelihood of prices remaining depressed and going down further is very high.
According to Fei-Jain Wu, chairman of Chipbond Technology, a backend service provider, the COF tape market experienced a price war that brought significant downward pressure on the profitability of Japanese suppliers. Wu doesn’t expect the LCD driver sector material shortage situation to ease. Back-end packaging and testing capacity will continue to be tight. If this situation continues there will be a shortage of driver ICs and therefore finished LCD modules. This shortage comes at a time when demand for LCDs are starting to grow.
Capacity Rising Chipbond’s wafer testing and COG packaging is at full capacity. The company’s COF production capacity is expected to hit 90 percent in the second quarter. Other backend service companies including King Yuan Electronics (KYEC), International Semiconductor Technology (IST) and ChipMOS Technologies also have seen their production utilization rates increase to 80 percent or more.

Update Here is some updated information about the world’s thinnest 42-inch and 47-inch LCD TV panels: Viewing angles are 178/178; the LCD panel is 10-bit; and brightness is 450 cd/m2. Power consumption is 110W for the 42-inch model and 130W for the 47-inch. Availability is undecided at the moment.
Original Post
World’s Thinnest LG Display announced on May 19, 2009 the world’s thinnest 42-inch and 47-inch 1080p LCD TV panels making use of edge-lit LED backlights. The LCD panels are just 5.9mm thick (0.23-inch). LG Display also incorporated the company’s proprietary LGS (Light Guide Sheet) technology that reduced thickness by half compared to typical LGPs (light guide plates).
Light The world’s thinnest 42-inch and 47-inch LCD TV panels are also very light at just 6.1kg (13.42lbs) and 7.3kg (16.06lbs) respectively. These are roughly 1/2 the weight of typical LCD TVs that employ CCFL backlights.
Performance The color gamut has improved from a standard 72% NTSC to 80%. LG Display also incorporated 120Hz technology to reduce motion blur and clocks in at a motion picture response time (MPRT) of just 8ms.
LCD TVs of the future will be thinner, lighter, consumer less power, better color gamuts, and very decent front screen performance. What is missing here is local dimming but I hear that companies are working on pairing that with edge-lit LED backlighting.
On Target Jim Flaws, CEO of Corning, reassured investors on Monday, May 19, 2009 that the company is on track to reach its 18% year over year growth rate for LCD glass substrate shipments on an area basis. Flaws, speaking at a JPMorgan tech conference held in Boston, told investors that the company needs to hit 10% to 15% quarter over quarter growth from the second quarter on.
We are planning on a build this quarter. But we are not expecting an increase like last year.
Cautiously Optimistic Looking at what Flaws said, it seems Corning will be cautious this time around. Corning has to look forward and match LCD glass demand that will materialize in the next 6 to 12 months. Building a LCD glass furnace facility takes about 6 months. If a LCD manufacturer is adding capacity or building an entirely new LCD fabrication plant, Corning will need to add capacity to fulfill that future demand and start building now. Of course LCD suppliers don’t have crystal balls and some times add capacity because they simply have the money to do it or due to competition against time and competitors.
We’d like to get back to the pricing model we were on in 2007 and most of 2008.
Stable Pricing That pricing model Flaws was mentioning is based on scheduled decreases of LCD glass substrate area prices on a quarter over quarter basis. Corning is able to do this since it is operating in what you might call an oligopoly with just two major LCD glass suppliers capturing more than 80% market share: Corning and AGC (Asahi Glass Co.). This helps both Corning and AGC normalize revenue streams and minimize rapid price declines.

Pale LG and Samsung each announced, on May 17, 2009, that the company has sold 20 million touchscreen phones in about two years. LG and Samsung has developed some very cool smartphones in the last couple of years. Samsung will be unleashing its 3.2″ OLED touch Android I7500 smartphone soon while LG has been quietly bombarding the world with a ton of touch smartphone models. But these numbers pale against the leaders: Nokia, RIM and Apple.
Leaders Take Apple for instance. Apple’s numbers are easy to analyze since the company has a single touch smartphone, the iPhone. Apple sold 11.4 million iPhones in the fourth quarter of 2008 (Source: The iPod Observer). That’s just one phone and for one quarter. According to Gartner, in the fourth quarter of 2008, Nokia was on top followed by RIM with a 19.5% market share and Apple with 10.7% (Source: Mobile Burn). Sources indicate that Apple will be launching an enhanced iPhone in June during the WWDC or at a small press conference in Cupertino soon after. RIM will be announcing its Storm 2 soon and Palm’s Pre will launch in the first week of June. Nokia will also be launching its N97 very soon.
Popular Overall smartphones are quite popular: According to NPD 23% of all mobile phones sold in the US were smartphones in the fourth quarter (Source: Top News). Smartphones generally have larger screens (LCDs and OLEDs) and should bode well for LCD manufacturers playing in this space. iSuppli expects smartphones to grow 11% year over year to 192 million units in 2009 (Source: Cult of Mac).

According to the New York Times, Palm’s Pre (NASDAQ: PALM) will be launching in the first week of June. Interestingly, Apple’s Worldwide Developers Conference (NASDAQ: AAPL) is on the second week of June. Will Palm’s Pre meet its stratospheric expectations? Will its introduction dampen excitement surrounding the next iteration of the iPhone? Or will the Pre, iPhone and other Google phones lift the entire smartphone boat? We live in exciting times…

China LCD TV demand from China is having a huge impact. Industry sources are saying that due to the strong demand from China for LCD TVs, LCD panel prices will continue to increase through June. The demand increase is largely affecting AU Optronics (NYSE: AUO) and Chi Mei Optoelectronics (TPE: 3009), two of the largest LCD suppliers in Taiwan. Other LCD suppliers such as Samsung, LG Display (NYSE: LPL), Sharp, etc. are still cautious about a global recovery for LCD goods.
25 Million LCD TV sales in China was originally expected to hit 18 to 20 million units in 2009. That number has now increased by up to 25 percent from 24 to 25 million units. This boost in LCD TV demand from China should have a positive impact on companies that are related to AUO and CMO’s supply chain such as suppliers for LCD glass, backlight units, optical films, LED chips and integrators.
Fickle Demand Brands will need to watch out for rising prices since that will erode profit margins on products they sell. If LCD panel prices rise too much brands will be forced to raise prices or eat profits in order not to dampen demand that is already fickle.

Although there are really advanced resistive technologies out there capacitive is generally better when it comes to things like smartphones. If rumors coming out of DigiTimes is true, Nokia is tapping Synaptics to enhance its mobile phones and smartphones from resistive to capacitive touch. These phones will be launched in the third quarter of 2009. Sources also noted that multi-touch could be a possibility. Synaptics is considered the leader in capacitive touch technology and currently supplies touchscreen ICs to Samsung, High Tech Computer (HTC), Research in Motion (RIM) and others.
