[iMiD 2017] TCL, Development focusing on Solution process OLED and QLED

/in , , , , /by

TCL’s Xiaolin Yan CTO addressed solution process OLED TV and self-emitting QLED TV as premium TV after white OLED TV at iMiD 2017 keynote address in BEXCO, Busan on 29th.

Yan CTO noted that white OLED TV, which is currently leading the premium TV market, meets all the requirements of premium TV due to its superior image quality, design differentiation, high resolution realization and nature-friendly characteristics compared to QD LCD TV.

In addition, the price that is higher than the current QD LCD TV is expected to be overcome by applying the solution process, and mass production is also expected in 2019.

Yan CTO predicted that the “solution process would be easy to produce 75-inch panels at Gen 10.5 because the process can be performed without splitting the ledger,” and “it is also possible to produce full-emission RGB OLED TVs.” However, he emphasized that the compatibility of materials and equipment and the development of ink forming process technology should be done.

Following to that, “QLED structure is very similar to OLED structure, so it is easy to apply the technology because of the low entry barriers,” he said. “The lifetime and efficiency of the blue light emitting layer compared to the current OLED is very low, and performance must be ensured without the use of cadmium.”

Lastly, He mentioned the establishment of printing technology in Guangdong JUHUA to promote the commercialization of solution process OLED TV and self-luminous QLED TV, and emphasized the cooperation of material, equipment and panel makers to develop next-generation premium TV.

Competition for definition in Premium TV market is getting fierce.

Competition for definition of TV between LG OLED TV and Samsung QD-LCD TV is getting fierce in Premium TV market.

Samsung announced that ‘color volume 100%’ of QD-LCD TV has been verified from VDE(Verband Deutscher Elektrotechniker), a standard verification association in Germany for the first time in the world. Color volume is a new standard designed to measure even the variation of colors which get different according to brightness as the range of brightness which TV can express gets wider and it’s a standard to measure how accurately TVs realize the intention of an original author. Samsung announced that VDE verified color volume 100%, measuring color area and brightness level of QD-LCD TV in a 3 dimensional form.

On the other hand, in last Feb. 20, through its blog, LG also announced that it has received an evaluation of excellence for definition of OLED TV in items of Black, Peak brightness, Color, etc. in the result of a recent definition test of OLED and QD-LCD from Burosch in Germany, a professional evaluation company for video technology and display. Products whose definition were evaluated are TV 65E6 and QD-LCD TV 65KS9800, and LG announced that OLED TV recorded 5 points out of 5 in major test results such as HDR and SDR definition.

As Samsung and LG launch premium TV in a row, a real competition to hold a lead in premium TV market has started. On 27, by Bestbuy, price of 55 inch C7 of OLED TV which LG launched this year is US$ 3,499.99, and US$ 2,499.99 of 55 inch Q7 of Samsung and Q8 which is more luxury type than that is getting closer to US$ 3,499.99, so the competition for definition is predicted to get more fierce in the future.

Many people are paying attention to which one will hold a lead in the competition for definition of premium TV between QD-LCD TV which hold a lead in the aspect of brightness and OLED TV which holds a lead in the contrast range, response speed, etc.

LG Display, announcement on development trend for OLED TV and latest WOLED device for lighting in IDW 2016

In IDW(International Display Workshops) 2016 held in Fukuoka Japan from December 7~9, LG Display announced on the development trend for OLED TV and latest WOLED device for lighting, and mentioned that the color area of latest WOLED device for OLED TV increased from 114% to 129% compared to sRGB, and 90% to 99% compared to DCI. In the paper, 3 stack structured 55” UHD OLED TV shows 150cd/m2 in full white screen, 500cd/m2 of luminance in peak white screen, and showed that it lowered the power consumption by 20% compared with 2 stack structure.

Also by introducing WOLED for lighting, LG Display mentioned that lighting WOLED has 3 stack tandem structure with green-red/blue/green-red, where WOLED for OLED TV has 3 stack tandem structure with blue/yellow-green/blue. It showed high efficiency of 90lm/w by applying Ag cathode and light extraction film which the reflectivity is high, and the color temperature is 2,850K which is in the warm white range, CRI showed characteristics of 88. This OLED light will start its production in 3rd quarter of 2017 in 5 generation line.

Meanwhile, LG display exhibited 800 nit 65” UHD OLED TV during OLED summit 2016 held last September in San Diego where they gained much interest compared to 65” curved QD-LCD TV quality, and it is expected that they will introduce OLED TV with improved luminance with more than 1,000 nits next year.
