-- OLED --

Korea’s top panel names Samsung Display Co. and LG Display Co. are on path to exit from LCD business to concentrate fully on organic or quantum dot displays to keep Chinese rivals at bay.

Despite turmoil from virus pandemic, Samsung Display is committed to its LCD phase-out by the end of 2021 to back proprietary quantum-dot (QD) technology as its mainstay panel. In October last year, the company unveiled a plan to invest total 13.1 trillion won ($10.7 billion) on QD display plants and R&D projects through 2025.

The company currently is converting its existing LCD lines to make large-sized QD displays. Its first QD display plant in Asan, south of Seoul, is scheduled to start operation in the first half of next year to produce 30,000 sheets of 8.5-generation display panel per month for 65-inch screens.

Samsung Display is concentrating its efforts on the conversion for commercial production of QD displays next year, said an industry expert. The company reportedly is also seeking new clients aggressively to replace LCD customers.


LG Display also has been accelerating migration to OLED. The company will stop producing LCD panels for TVs in Korea by the end of this year. The lines will turn out smaller LCD panels for car screen, monitors and laptops. The company aims to generate more than 50 percent of its revenue from OLED business from next year, now that OLED plant in Guangzhou, China becomes fully operational this year.

The company recently carried out massive restructuring including layoffs for its LCD business. Also, its management reportedly is negotiating with labor union on changing work hours to cut production costs.

The migration has gained speed after Chinese display panel makers began to jump in the OLED market. China Star Optoelectronics Technology, subsidiary of Chinese electronics maker TCL Technology, is building a factory to produce large-sized OLED panels for TVs. Another Chinese maker HKC also is readying to make large-sized OLED panels with a target to start mass production next year.

Βλακώδης γουγλική μετάφραση μάλλον στα Ελληνικά.
Η αντίστοιχη στα αγγλικά είναι: ""The OLED panels produced in the new LG Display factory in Guangzhou have exceeded LG Electronics quality standards, a necessary step for the transition to mass production, on which however the unknown Covid-19 weighs"
Όπως σωστά έγραψε ο Ducksong.
 
H TCL θα επενδύσει στην κατασκευή inkjet printing OLED τηλεοράσεων με RGB pixel.

Με σημερινή της ανακοίνωση η TCL θα επενδύσει 250 εκ ευρώ στην ανάπτυξη μεγάλων OLED τηλεοράσεων αποκτώντας το 10% της ιαπωνικής εταιρείας JOLED που ειδικεύεται στην εν λόγω τεχνολογία.

We spoke to Marek Maciejewski, director of product development at TCL Europe, to clarify rumours about the company launching QD OLED (quantum dot OLED) by the end of this year.

Marek said that there has been a misunderstanding on the part of the reporter who broke the story, and that TCL is launching a QD OLED TV, but only next year (2021).

He refused to be drawn on who is supplying the QD-OLED panel, but since realistically there's only one TV-sized QD-OLED panel supplier on the market at the time we filmed this video in September 2020, it's likely to be coming from Samsung Display.

We explain why Samsung's 2021 TV next year won't be using QD-OLED (quantum dot OLED) technology, even though Samsung is replacing its LCD production fab with QD-OLED manufacturing equipment.

The key to understanding the distinction is that there are two separate entities: Samsung Display (which manufacturers the QD-OLED panels), and Samsung Visual Display Business (otherwise known as Samsung VD) which makes the actual televisions you can buy.

LG Electronics has filed trademark applications in the European Union for QNED which stands for Quantum Nano Emitting Diodes, a next-gen display self-emissive technology using GaN-based Nanorod LEDs as blue light emitter.

However, as far as we're aware, Samsung Display is the pioneer behind QNED technology, with plans to convert its QD-OLED manufacturing line to QNED once QNED is out of the R&D phase.

In this video, we also explain the structure of QNED technology.

LG Innotek Develops High-Efficiency Magnetic Material, Advancing the Era of Ultra-Slim OLED TVs Under 2cm Thick

  • Ultra-slim TV and lightweight vehicles with improved energy efficiency
  • Reduced development period to 1/4 of projected time, achieving world-class performance
  • Internalization of core materials to provide differentiated customer value


LG Innotek announced on the 19th that it has successfully developed a high-efficiency ferrite with the lowest power loss in the world. This development has contributed to LG Innotek's dominance in the TV and vehicle power markets.

LG_Innotek_s_high_efficiency_ferrite.jpg



Ferrite is a magnetic material with iron oxide as its primary raw material, and ferrite powder is hardened into a tile shape for industrial use. It is usually installed in TV power modules, vehicle power sources, and chargers (On Board Charge, OBC) to change the voltage or remove unnecessary signals generated by current surges. This provides a stable power supply to display panels for TVs and air conditioners, as well as audio systems for vehicles.

As home appliances and electric vehicles have become increasingly smaller and more functional, high-efficiency ferrite– which is advantageous for ultra-slim and high-efficiency products– is being touted as a next-generation material.

The high-efficiency ferrite developed by LG Innotek has a maximum of 40% less power loss from heat compared to general ferrite. In addition, its low-loss characteristics are maintained at temperatures of -40℃ to 140℃, giving it the advantage of realizing perfect quality in high-temperature TV interiors and various driving environments.

  • Ultra-slim TV and lightweight vehicles with improved energy efficiency

LG Innotek's high-efficiency ferrite is advantageous in making ultra-slim TVs and reducing the weight of vehicles to increase fuel efficiency for electric and hydrogen vehicles.

Using this material allows a 60% reduction in TV thickness by making the TV power module only 9.9mm, the thinnest in the world. The normal thickness of a 65-inch ultra-slim OLED TV equipped with a general power module is about 46.9mm. When a high-efficiency ferrite power module is applied, the thickness can be reduced to 20mm or less. This is because the number of components for securing the required power is reduced by 1/3 due to low power loss.

In addition, high-efficiency ferrite can increase the energy efficiency of TV power modules up to 5%points. As the energy efficiency of a component increases, heat generation is reduced and the damage caused by heat minimized, thereby extending the life of the component.

When this product is applied to a vehicle DC-DC converter, the volume and weight of the converter can be reduced by 10% compared to the previous model, and the energy efficiency of the converter can be increased up to 1.2%points.

It also helps reduce the risk of fire due to the overheating of vehicle power. The low heat generation of high-efficiency ferrite can lower the temperature of components by up to 20℃ compared to previous models.

  • Reduced development period to 1/4 of projected time, achieving world-class performance

In the field of ferrite, Japanese companies have dominated the market with the No. 1 technology in the world. However, Japanese products have been expensive and difficult to supply.

In response to this, LG Innotek became fully engaged in the development of high-efficiency ferrite starting in 2018. Since LG Innotek decided it would be difficult to close the gap with Japanese products using existing development methods, LG Innotek has applied simulation techniques such as digital transformation (DX) and artificial intelligence (AI) methods to design materials for the first time in the industry.

LG Innotek automates the process of finding the best-performing material composition ratio with supercomputers, greatly reducing the time and frequency of experiments while enhancing the accuracy of results. In the past, researchers conducted thousands of direct experiments to find the optimal ratio, which took a long time and was susceptible to user errors.

By making active investments in employing the latest software, technical advices, and industry-university cooperation, LG Innotek has successfully shortened their development period from a projected four years to only one year and four months.

  • Internalization of core materials to provide differentiated customer value

LG Innotek's strategy is to strengthen its competitiveness by expanding the application of high-efficiency ferrite, a core material for its products.

In addition, LG Innotek is actively pushing ahead with promotional activities for global electronic companies and automakers with the aim of mass production of materials in the first half of next year. Also, in order to solidify its position as the No. 1 technology company in the field of high-efficiency ferrite, LG Innotek is spurring the advanced development of materials with improved performance based on approximately 120 related patents.

"It is a significant achievement that LG Innotek's unique method of internalizing core materials in a short time has enabled us to provide a stable product supply with the best performance and quality to customers," said Bae Seok, a research fellow of Magnetic Components Task in LG Innotek's CTO Division. "We will continue to provide differentiated value to our customers by utilizing magnetic materials," he continued.

Σύμφωνα με στοιχεία που δημοσίευσε η LG οι νέες τηλεοράσεις OLED του 2022 θα έχουν 300.000 ώρες ζωής του πάνελ δηλαδή 300.000 ώρες πριν αυτό χάσει το 50% της αρχικής του φωτεινότητας και καταστει αδύνατη η παρακολούθησή του.

Ακόμα και με 12 ώρες παρακολούθησης την ημέρα τα πρώτα σημάδια που η μείωση της φωτεινότητας θα γίνει αντιληπτή από το θεατή (LT95) θα έρθει μετά από 7 χρόνια ενώ με 8 ώρες παρακολούθησης την ημέρα αυτο θα συμβεί μετά από 10 χρόνια.

Οι μετρήσεις έγιναν με βάση το μέγιστο επίπεδο φωτεινότητας που μπορεί να σηκώσει το κάθε πάνελ.
