What is the future change of WRGB OLED to respond to QD-OLED?

2As Samsung Display’s QD-OLED begins to be applied to TVs and monitors in earnest in 2022, technological changes are being detected for LG Display’s WRGB OLED, which has been leading the large OLED market.

LG Display’s WRGB OLED has produced a WBC structure consisting of two blue layers and one red+yellow green layer in Paju by the end of 2021, and a WBE structure consisting of two blue layers and one red+green+yellow green layer in Guangzhou. Deuterium substitution technology was applied to the blue of the WBE structure.

Since 2022, LG Display has stopped producing WBC panels from its Paju line and has been producing ‘OLED.EX’ panels with deuterium substitution technology applied additionally to green of WBE produced in Guangzhou.

At SID 2022, LG Display also exhibited a large OLED panel with micro lens array technology. Micro lens array technology was applied to Samsung Electronics’ ‘Galaxy S Ultra’ series, and it is the first technology applied to large OLEDs. LG Display is known to expect a 20% improvement in luminance compared to the previous one by applying micro lens array technology. Panels which micro lens array technology is applied are expected to be produced in Paju from the second half of this year.

Lastly, it is known that LG Display is developing a structure in which yellow green is removed from WRGB OLED. By eliminating yellow green, material and processing costs can be saved, and color gamut is expected to be improved.

Attention is paid to how LG Display’s WRGB OLED will evolve to compete against QD-OLED.

[2022 OLED KOREA CONFERENCE] LG Display Executive Vice President Hyun-Woo Lee, Advancements in the Display Market with Technological Innovation that Suits Changing Lifestyles

Executive Vice President Lee explained OLED technology innovation, future application fields, and market changes. He mentioned that COVID-19 has increased everyone’s time at home and changes in life display is necessary to match it.

Executive Vice President Lee first explained LG Display’s OLED.EX, and said, “LG Display’s OLED.EX is the most advanced OLED panel to which EX technology is applied. OLED.EX applies deuterium to increase brightness (an important element in OLED panels) by 30%. Through personalize algorithm based on AI and big data, reliability will be increased.” He also emphasized that “LG Display’s OLED.EX will be applied to all OLED TVs in the second quarter of 2022 and LG Display will lead the display market with innovative technologies including OLED.EX.”

Next, Executive Vice President Lee announced about life displays applied to everyday life, and said, “OLED is applied to life displays such as gaming, transparent, and portable displays. OLED realizes 100% original color to increase the sense of reality and enables excellent interaction with eye care, making it suitable as a gaming display.” Also “Transparent OLED maximizes the advantages of OLED, enabling the highest level of transparency and picture quality. By applying it to signage, it provides an effective experience to customers, and by applying it to mobility, it can use the dead space to indicate the current operation status or use it for advertisements. In addition, it is possible to create a space of new value and change a creative lifestyle by applying it to life”.

‘2022 OLED Korea Conference’ was a conference for exchange of ideas, business relationships, and partnerships with renowned speakers from major companies in the display industry from all over the world. ‘2022 OLED Korea Conference’ held a business conference on the 7th and 8th, beginning with a tutorial on April 6th.

 

LG Display Achieves Record Sales in 2021, Swinging a Profit after Three Years

 

As LG Display posted the highest sales ever, at the same time it also made a sharp pivot into a profit for the first time in three years. On the 26th, LG Display announced that it had achieved annual sales of 29.878 trillion won and operating profit of 2.23 trillion won in 2021. “This is the result of the large-sized OLED panels in the premium market, the strengthening of the small and medium-sized OLED business base, and the innovation of LCD structures centered on IT products,” LG Display goes on the explain. While the overall TV market experienced negative growth last year, LG Display led the large-sized OLED business. OLED TV panel shipments grew by more than 70% compared to the previous year, which turned to profit in the second half of the year. This helped reach a break-even point.

Following the previous year’s earnings announcement, LG Display stated, “This year, we plan to expand profitability in stages based on shipment growth of more than 20% compared to the previous year and strengthened business capabilities,” and “From the second quarter, ‘OLED.EX’ will be applied to all OLED TV panel series to accelerate the trend toward OLED in the premium TV market.” OLED.EX is a TV panel that increases screen brightness (luminance) by 30% and reduces bezel by 30% by applying ‘deuterium technology’ and ‘personalization algorithm’ to organic light emitting devices. These are the core elements of OLED picture quality. In the case of small and medium-sized OLEDs, the mobile sector plans to improve profitability by expanding new models and high-end products in the second half of the year and expand to the overall mobility industry. The LCD division will continue its strategy of selection and concentration focusing on IT products.

LG Display also expressed confidence in Samsung Display, which has emerged as a new competitor in the OLED market. When asked about LG Display’s competitiveness compared to Samsung Display’s QD-OLED, Large-Scale Marketing Manager Lee Tae-Jong remarked, “Our competitor’s products have not been released yet, so an accurate comparison will be possible only after the actual launch.” He continued, ”LG Display, which has been in business for more than 10 years is far superior in our overall competitiveness in our products and cost, economies of scale, and customers. We will continue to widen the gap in the future.”
