<3>Display Innovation
The evolution of the display is currently ongoing. Organic light emitting diodes (OLEDs) are diversifying in shape and form from flat to bendable, foldable, and rollable. Due to the spread of non-face-to-face and remote culture from COVID-19, the importance of displays is growing. The development of next-generation products such as micro light emitting diode (LED) displays is advancing.
On September 8, the third day of 'Global Tech Korea 2021,' Samsung Display and LG Display, which are leading the world in display technology, and innovative companies in the materials, parts and equipment (general manager) fields that enable the commercialization of next-generation displays will participate in the presentation. It is expected to experience the development of display technology and industry trends at the event.
On the 8th,Samsung Displayexecutive vice president Changhee Lee will introduce changes in display technology in terms of △form factor, △power consumption, and △color expression, and announce the direction of future development in the keynote speech. Vice President Lee is the head of the next-generation research department at Samsung Display, and an expert in the field.
OLED is evolving into a mass-produced product that can be folded or rolled in a direction that can reduce the edge area and utilize the screen 100%. The display application is expanding not only to smartphones but also to information technology (IT) products such as laptops and monitors. Vice President Lee will share OLED's form factor change, power consumption reduction, and color expression improvement technology.
Jeom-jae Kim, head of LG Display's Basic Technology Research Center, will introduce the display industry, which is facing new opportunities due to COVID-19. While the display market is revitalized due to non-face-to-face and the spread of remote culture, the price of LCD, which was treated as an outdated product, has risen. The change will not only revitalize the market, but will also bring about convergence with other industries and the birth of new application fields. Kim will introduce LG Display's OLED and next-generation display technologies to make life easier for customers, and initiate eco-friendly and sustainable management efforts through environmental, social, and governance (ESG) management.
Materials are essential in display innovation. Materials are the basis of the display.
Martin Curran, executive vice president of Corning's chief innovation officer (CINO), who has been innovating in the materials field for the past 170 years, will come as a speaker. Executive vice president Curran shares examples of responding to market changes and investing in key growth areas. Micro LED-related technologies, mobile camera lens covers, and pharmaceutical glass packaging solutions will be introduced. In addition, executive vice president Curran will share new technologies that Corning is focusing on, such as laminated glass solutions that realize thinner and lighter functional architectural glass, and flexible substrates for next-generation high-performance batteries.
Material companies that cannot be excluded from OLED will be speakers as well.
Tae-hyung Kim, Head of Solus Advanced Materials' Electronic Materials Business Division, will announce OLED material technologies that will contribute to the development of the display industry. Key OLED material technologies such as the company's main business, hole blocking layer (HBL) and hole transport layer (HTL), which are companies main products, as well as quantum dot (QD) ink, will be shown at the event.
Bum-sung Lee,, head of business division at Duk San Neolux, will introduce material development trends to improve power consumption, which is a continuous process in the OLED industry. Lee will also share technology and material change information as display form factor changes accelerate.
Equipment companies will also participate in Global Tech Korea 2021.
ITI CEO Seok-jun Lee, who is drawing attention in the field of ultra-thin glass (UTG) processing that completes the transformation of the display form factor, will introduce laser technology that can be applied to displays, semiconductors, and secondary batteries. He will present applied examples and promising prospects as well.
Kyu-yong Bang, director of Top Engineering, will introduce a non-contact high-speed inspection technology that can detect more than 3000 electrical and optical characteristic defects and wavelength defects per second on wafer micro LED chips. Micro LED is an ultra-small LED of less than 100 micrometers (㎛), and is attracting attention as a next-generation display in which a chip becomes a pixel.
Nam-sung Kim, CTO of Laserssel, a venture company that makes world-class laser reflow equipment, will introduce next-generation laser bonding technology and repair technology for mini-LED, micro-LED, and OLED displays, and will share the direction of development. Kim will explain a technology that converts the central peak-type Gaussian beam shape into a uniform surface light source laser beam by passing it through a beam shaping optic module (BSOM).
'Global Tech Korea 2021' will be broadcast live on the online website. Those who pre-register on the website can watch it for free. Simultaneous interpretation in English is also provided in order to fulfill the purpose of the global technical cooperation conference. Pre-registration is until September 3rd.
