LG Electronics’ 77” Curved OLED TV for£20,000

LG Electronics’ 77” UHD curved OLED TV displayed at CES 2014 attracted attention of many foreign visitors. According to a Chinese medium, Shanghai Hotline, LG Electronics (LGE) officially launched the 77” UHD curved OLED TV, for £20,000 (about 34.6 million Kwon) in the British market. Official from LGE says, however, we are just planning to sales 77” UHD curved OLED TV.

With 4K UHD resolution (3840×2160), the 77” OLED TV offers a high picture quality, providing close to nature images, and comfortable viewing experience. Its unique design of curved screen and ellipse shape stand also allows you to enjoy high-contrast colorful pictures from any angle. This 77” UHD OLED TV won ‘Best of Innovations” award at CES 2014, and moves 7.5cm to bend so it moves 8cm to bend from flat and its angle is also adjustable.

LGE plans to launch 65” UHD curved OLED TV for £6,000 (about 10.3 million Kwon) with the same features as the 77” TV in this October.140704_LGCES201477inchamoled

Samsung, introducing ‘Galaxy S5 mini’ targeting the world market

Samsung Electronics announced Galaxy S5 mini, a new Galaxy series. Its design is similar to the previous model but not the specifications.

Compare it with the previous model, its panel is a 4.5” HD AMOLED which is smaller than the 5.1” FHD AMOLED panel, and lighter by about 25g weighting 120g. Main specifications include quad core 1.4GHz CPU, LTE, 1.5GB memory, 16GB storage, Android 4.4 and 8 mega pixel camera. Galaxy S5 mini has features are waterproof, dustproof, finger scanner and ultra-power saving mode like Galaxy S5.

The galaxy S5 mini colored as the Galaxy S5 is planned to hit the global market after launching it in Russian market in early July.

Samsung Electronics has been continuously introducing new models from the Galaxy S3 to S5 including an entry-level model, mini.140703_GalaxyS5mini

Yamagata University develops low-voltage blue phosphorescence material

According to a Japanese media, Nikkei, organic device engineering professor Junji Kido of Yamagata University has developed a low-voltage blue phosphorescent material. It is a material that can be driven with a low-voltage of 2.5V and its external quantum efficiency is high as 30%.

Yamagata University has published a paper on a new material on a science magazine, 『Advanced Materials』, issued on June 27th, 2014. The peak of this materials wavelength is 474nm (band gap is 2.62eV) and the reduction of quantum efficiency is small in high brightness zone. Also, the external quantum efficiency is 30% in 100cd/m2 and 20% efficiency can be maintained in high brightness of 10,000cd/m2.

Yamagata University actively develops TADF (Thermal Activation Delay Fluorescent) technology, which makes fluorescent material to realize the similar efficiency close to phosphorescent material, and white OLED using printing technology other than the blue phosphorescent material.

Skyrocketing interest of Panel makers in blooming smart watch market

Set makers are launching various smart watch products such as Galaxy Gear and Gear Fit by Samsung and G-Watch by LG after the smart watch by Sony. With this, display companies accelerate development and mass-production of panels for the smart watch.

At present, OLED, LCD and e-paper are the panels applied to the smart watch. Also the flexible OLED is preferred for the wearable smart watch. Samsung Display is currently mass-producing the flexible panel for the smart watch, and LG Display will also start to manufacture them in the latter half of this year. Futaba of Japan has completed the development of PMOLED for the smart watch panel, and AUO introduced an ultra-thin OLED panel showing its at SID 2014 will to enter the panel market for the smart watch.

Shipments for the world’s smart watch market in 2014 are expected to 7 million but Apple Inc., aims to sell 9 million products in 2014. Thus, the smart watch market is a business with high potential to grow explosively and is where fierce technology competition will be between the panel makers.

UDC’s New Technology, Improving lifespan and power consumption of OLED Display

UDC presented a paper on a new technology that reduces power consumption and increases lifespan than the existing RGB-FMM method at SID 2014.

Under the title of “Novel Two Mask AMOLED Display Architecture,’ the paper describes the new technology to reduce to 2 mask from the existing RGB-FMM using 3 mask. In details, each pixel is divided into 2 regions; yellow and blue, and evaporation is performed with the yellow and blue masks. This technology is to form a pixel structure of YRGB by developing a color filter of red and green on the yellow region

UDC describes that the technology reduces the resolution by 33% compare to RGB FMM, but the increase of the blue region will increase the overall lifespan and decrease the power consumption of the display. It also announced that it could lower the production cost by reducing tact time and improving yield rate.

Like UDC, the industry develops various technologies to reduce the yield rate and cost of the AMOLED, and further continuous development of the AMOLED is expected.

LG Display’s winning move, OLED TV Price

140627_LG D Workshop

 

LG Display (LGD) actively competes in TV market by reducing OLED TV price.

A department head Byeonggyu Roh of LGD emphasized “cost reduction of LGD’s OLED panel should be carried out across all processes and continued” and introduced its cost reduction strategy for the OLED panel for the 2nd Annual OLED Workshop held on 24th.

Key cost reduction strategy includes various ways such as investment cost reduction by rearranging the existing lines and modifying equipment; material cost reduction by optimizing the thickness of layers for TFT, the OLED and encapsulation; tact time improvement; and production efficiency increase by investing in M2 line. Also it was expected that soluble process will be the core technology for cost reduction in the future.

CEO of UBI Research, Choong Hoon Yi, said “LGD’s ultimate goal is to reduce the price by 1.1 times compare to LCD” and announced “cost down can be realized through reducing investment cost as 65” UHD OLED TV displayed at SID 2014 applied the existing co-planar to reduce from the previous 6mask to 4mask.”

LGD recently began supplying the OLED TV panel to China, and it plans to operate the M2 line in the latter half of this year. It also dropped the price of a 55” FHD curved OLED TV to $3,999 from the released price of $15,000 and a price war with the LCD TV is about to begin.

Samsung Display’s super AMOLED of Galaxy Tap S scored the highest ever

Galaxy Tap S, which applied Samsung Display’s (SDC) super AMOLED panel, recorded the highest score of Excellent A in the comprehensive evaluation by a professional display group in the U.S., DisplayMate. The Galaxy Tap S surpasses the previous winners of Kindle Fire HDX 8.9”, the 1st, and iPad Air, the 2nd, and topped the list with the AMOLED not LCD. This will be a new energizer for the OLED market.

SDC’s super AMOLED panel adopted by the Galaxy Tap S is WQXGA (2560 x 1600) and scored the highest points in color reproduction categories such as color gamut and color accuracy among various evaluating categories of DisplayMate. With such high score, it is rated as a professional monitor with excellent picture quality. Achieving ‘Excellent A’ in outdoor visibility category showed that it is not far behind in brightness and better in viewing angle and contrast compare to the LCD. It was a chance to show the customers that the OLED excels the LCD.

SDC unveiled the super AMOLED panel for the first time at SID 2014. M6, which is a upgraded luminescent material from one used in the Galaxy S5, is applied and shows excellent performance.

Finding a way for OLED industry in flexible

Samsung is preparing to introduce foldable AMOLED panel applied mobile product, and LG will release a new product with the flexible AMOLED panel in the latter half of this year.

As the flexible OLED commercializes, its R&D also accelerates. It was analyzed that the trend of papers published at SID 2014 is the flexible OLED as 9 more papers totaling 23 regarding the flexible OLED were published at SID 2014 than 14 papers 2013.

SEL displayed its best technology in the flexible OLED by introducing a tri-folded AMOLED panel, a book type AMOLED panel, and 13.5” and 5.2” high resolution flexible AMOLED panels at SID 2014. AMOLED latecomers such as AUO, BOE and CSOT also published papers on the flexible AMOLED panel and showed that more display companies are entering the flexible OLED development.

As such, active R&D on the flexible OLED is carried out by industry-academic-institute, and it is expected that the flexible will be more focused in the OLED display sector. A keyword of the flexible will differentiate it from the LCD and is expected to lead the display industry.
