CES2019, the Biggest Issue of TV is LG Electronics OLED TV R

/in , /by

Reporter : Daejeong Yoon

The CES, held in early January of each year, is the most important event to understand all of the consumer electronics trends of the year. This year, TV makers from all over the world exhibited a variety of products to attract spectators to the event.

When OLED TV occupied more than 50% of the premium TV market with more than $ 2,000, the LCD TV industry sought to prevent the OLED TV market from expanding by exhibiting 8K LCD TVs to CES. However, the attention and admiration of the spectators were poured into OLED TV R.

The 8K TV market began to open slightly from last year, in preparation for the 8K broadcast starting from the Tokyo Olympics in 2020. LCD TV companies displayed 8K LCD TVs of various sizes to preoccupy the market with the keyword of 8K. LCD TV, however, has not been recognized by viewers as a new TV product since Sharp has already exhibited steadily.

Another reason is OLED TV R displayed by LG Electronics. In the main body with built-in speaker, OLED TV rises up and goes down again. A lot of people came to see OLED TV R to shoot.

Last year, micro LED TVs became more prominent. In addition to Samsung Electronics, Sony, TCL and Hisense exhibited micro LED TVs this year. It seems that the gap of micro LED TV technology between Korean companies and Chinese companies is only about one year. In the micro LED TV market based on assembly technology that does not require special manufacturing technology, China, which is the world’s best LED industry and infrastructure, is expected to dominate the market soon.

However, as LG Display has a unique OLED TV manufacturing technology, which has a very complicated panel structure and manufacturing process, the technological gap between Korea and China is expected to be more than five years difference. In this situation, OLED TV R, released by LG Electronics, once again realizes that Korea’s OLED technology is the best in the world.

On the other hand, TV companies’ display of OLED TVs, except for LG Electronics, has stagnated. These companies are not yet receiving 8K OLED panels and rollable OLED panels from LG Display. Even Sony does not have any special features, only OLED TVs that are well known so far.

As a result, the CES TV show was notable only for LG Electronics.

It is judged that LCD TV using mini LED that TCL has released can compete with OLED TV in this exhibition. The contrast ratio is displayed as 1,000,000: 1 similar to OLED TV. Black is a very good product that has a vibrant color and contrast ratio similar to OLED TV. However, a holo-effect was found around the bright screen displayed on the black desktop. It is a phenomenon that the surroundings appear to spread brightly. As it is invisible to non-specialists, it is competitive in price and is a product that can compete well with OLED TVs.

What is the next-generation display poised to outshine OLED?

/in , /by

The micro LED, QLED and hologram, which are referred to as the next generation displays, were presented at the seminar entitled ‘Recent Trends in Display and Vehicle Display Technology’ hosted by UBI Research on the 14th.

Under the theme ‘Technical Issues of micro LED Display and Market Trend’, professor Moon Dae-gyu of Soonchunhyang University said, “Micro LED can be realized in high resolution and it is easy to implement curved display or flexible display because there is no limit of panel shape and size” He added “When applying micro LED to a display, high resolution is feasible even on a small substrate size, so that it can be applied to VR, etc.” and expected “When applied to a public display, it will be able to escape from the method of tiling many display panels”. However, there remain some technical problems such as the problem of transferring and connecting millions of LED chips quickly and accurately, the deviation problem of color and luminous efficiency between LED chips, and the technical problem of implementing an active matrix for the application of a display.

Next, Dr. Hwang Do-Kyung of Korea Institute of Science and Technology(KIST), Dr. Bae Wan-ki, senior researcher of KIST, and Dr. Oh Min-Suk of Korea Electronics Technology Institute(KETI) announced the manufacturing principle of quantum dot and the possibility of self-emitting QLED using it. Dr. Hwang said, “The quantum dot has the advantage of not only color change depending on the size and but also narrow half width.” “Self-emitting QLED can display higher color purity than OLED.” he added.

Dr. Bae expected “If research is carried out on an enterprise scale, the speed of technology development will increase more rapidly.” saying that “At present, the efficiency of quantum dot devices is continuously improving, but the life span is insufficient compared to OLED.”

“We need the next generation display technology to follow the LCD and OLED,” said Dr. Oh Min-Seok of Korea Electronics Technology Institute(KETI). He added “QLED is attracting much attention as a next-generation display, but there remain such issues as too much focus on the development of emitting devices, the lack of solution process-related devices and technologies, and the non-cadmium-based high-efficiency blue light emitting devices”.

As the last speaker, Kang, Hoon-Jong, team leader of Korea Electronics Technology Institute(KETI) explained the digital hologram technology and its application, and emphasized that a display panel capable of expressing the hologram is necessary to implement it. He said “We have a holographic printer or a microscope but there is no enough technology to apply it to TV”. Then, he closed his presentation saying “We need to develop a film for hologram first and then a functional design that can implement the screen.”

During the presentation about the next generation display, many of the speakers emphasized the importance of cooperation and participation among schools, research institutes and companies in order to overcome technical problems and realize them as actual displays. The display competition is expected to become even more intense in the future, as R&D in micro OLED, QLED, and hologram, which are considered as the next generation display, is concentrated.
