LG Display says two of its research papers, relating to ultra-large organic light-emitting diode and stretchable displays, have achieved recognition as “outstanding works” at one of the display industry’s most renowned events of the year.
The company’s research papers received “Distinguished Paper” awards at this year’s Society for Information Display conference, which takes place from Sunday to Friday in Los Angeles this week.
Led by researcher Shin Hong-jae, a team from LG Display introduced a new technique that was applied to the development of ultra-large OLED displays of 80-inches and larger in a paper titled “A Novel Ultra Large Size OLED Display for Premium TVs." One of the problems with building larger OLED displays is that the technology suffers from a technical problem that makes it difficult to display uniform high image quality when the screen grows beyond a certain size. But by improving its panel and drive technologies, and by enhancing the performance of the individual OLEDs and reducing the size of the display’s bezel, the researchers were able to create a series of large OLED panels (pictured) that do display uniform, high-quality images.
The team applied its Meta Technology to significantly improve the brightness of OLED panels to 2,100 nits. They were also able to boost energy efficiency by around 22% by combining luminance enhancing algorithms with ultra-fine lenses that maximize the light emission from individual OLED pixels.
The Meta Technology-based OLED displays will feature on this year’s LG G3 and C3 OLED TV .
The second paper, "High-Resolution Active-Matrix Micro-LED Stretchable Displays,” was written by Jung Hae-yoon and his team, pertaining to the creation of superior, stretchable MicroLED-based stretchable displays.
Stretchable displays go further than the current generation of foldable OLED displays, as they can be folded, stretched and twisted into almost any kind of shape.
Hae-yoon’s research team successfully developed a 12-inch stretchable MicroLED display prototype (pictured) that can be stretched by up to 20% larger than its original size, while simultaneously displaying high-resolution images. The research was recognized by SID for dramatically improving the resolution, pliability and readability of stretchable display technology. SID believes it represents significant progress on the road to commercializing such technology.
LG Display’s chief technology officer Yoon Soo-young said the latest work is just the start, and that its research into these new display technologies is likely to advance much further in the years to come. "We will further bolster our technology leadership through the development of ultra-large, ultra-high definition displays and innovative form factors that deliver transformative customer value," he promised.
