LG Display, the LG business unit that produces video display panels for various uses including large-screen OLED and LED-LCD TVs, is exhibiting what it calls the “world’s first 77-inch flexible and transparent OLED display” at this week’s Society for Information Display (SID) conference in Los Angeles.

The 77-inch flexible OLED screen features Ultra HD (UHD) 3840×2160 pixel resolution, an 80R curvature, 40% transparency “and can be rolled up to a radius of 80mm without compromising any of its functionality,” LG Display said.

The company showed a similar 65-inch rollable OLED display screen and an 88-inch 8K OLED display last January at CES 2018.

“LG Display is proud to have a pioneering role in the 50-year history of LCD innovations by introducing world-first and world-best technologies such as IPS,” stated Dr. In-Byeong Kang, LG Display executive VP and chief technology officer. “We will continue to create innovations in the display industry by establishing a new display paradigm with OLED technology and opening another revolutionary chapter of display history.”

At the show, the company is using theme “Display Your Lifestyle,” to encompass a range of innovative display applications that offer differentiated value to customers. This ranges from OLED TVs to mobile and automotive displays.

LG Display is presenting 21 display technologies, highlighted by the flexible OLED screen and a “Study on enhancement of sound quality by improvement of panel vibration in OLED TV.”

Among other technologies at the event, LG Display said it is showing 55-inch and 65-inch UHD Crystal Sound OLED displays that, similar to the “Acoustic Surface” technology in Sony’s current 4K OLED TV models, “let sound emanate directly from the panels vibrated by exciters on the back,” LG Displays said.

The 65-inch UHD “Crystal Sound” OLED display will be named “Display Application of the Year” at SID 2018, the company said.

Among other display applications on review by the company are automotive display technology with sophisticated design and high picture quality based on Low Temperature Polycrystalline Silicon (LTPS) technology.

“LTPS is suitable for high-resolution display panels, as it offers more active electron mobility and less current leakage compared to the conventional Amorphous Silicon (a-Si) technology widely used in conventional LCD panels,” LG Display said.

The company said it is showing a 12.3-inch Quad HD (QHD) display that can replace the conventional analog cluster and a 16.2-inch display for the front passenger seat. Also featured is a 14.3-inch Center Information Display that incorporates LG Display’s “unique in-TOUCH technology.”

in-TOUCH involves the use of touch sensors inside LCD Cells to produce highly effective touch-screen sensitivity along with advanced design and visibility. It also uses an additional white pixel to improve the transmittance rate and in association with differentiated algorism, lowers power consumption.
