LG Display plans to expand the application range of organic light emitting diode (OLED) displays to various areas such as transparent displays and vehicles. They also showed confidence that OLED is the most suitable for responding to the rapidly increasing demand for future displays. He also presented the tasks that OLED must solve, such as developing new materials and securing stability.
Jeom-jae Kim, head of LG Display's Basic Technology Research Center, announced that the scope of OLED application in the future display market will be expanded through the keynote speech 'Future Life Changed by OLED' on the 3rd day of 'Global Tech Korea 2021'. This means that demand for OLED will increase rapidly in various fields, from existing smartphones and TVs to transparent displays, vehicle displays, and augmented reality (AR) and virtual reality (VR) devices.
“Compared to LCD, which uses various and complex parts, OLED has a simple structure and can change shape naturally,” said Director Kim, “It has strengths in terms of design and form factor.”
Director Kim cited the commercialized transparent OLED for railway by LG Display as a representative example of expanding the application range. LG Display supplied their independently developed transparent OLED to subways in major cities in China last year. OLED succeeded in popularizing in areas other than IT and home appliances. Director Kim added, “There are many advantages of OLED compared to LCD in increasing display transparency.”
He predicted that flexible and rollable OLEDs would replace tablet PC displays and that a home cinema environment would be built with thinner and lighter OLED TVs. He also predicted that OLED will be applied to AR and VR devices in education and entertainment fields.
“Entertainment display will also be applied inside the car for the window shield, sunroof, and rear seat. Because of these, demand for OLED will be long and stable.” said Director Kim. Following the successful development of the world's first P-OLED for vehicles, LG Display started mass production last year.
The characteristics of an eco-friendly display also support the expansion of the OLED area and increase in demand. This means that it can meet the various needs of the future display market. "In terms of environment, OLED consumes less power and has a higher reuse rate than LCD," said Director Kim.
Director Kim also presented the task of expanding the OLED base. It is the discovery and advancement of new materials. OLED red and green light emitting materials utilize phosphorescence with high efficiency, but fluorescent materials are still applied for blue due to its high technical difficulty.
“There must beinnovative material to increase the efficiency and lifespan of blue OLEDs,” said Director Kim. He also said, “In order to expand the application of OLED for vehicles, it is necessary to secure higher reliability than materials applied to existing devices.”
