Since the 1st OLED TV product came out in the market, OLED has gone through continuous technology development and remarkable achievement. As the one and only OLED TV panel-maker, LG Display is providing a whole new value and differentiated viewing experience with the most innovative OLED products. As the future display trend, OLED is truly changing our lifestyle and creating another future.

Sang Deog "Eddie" Yeo, chief marketing officer at the Korean consumer electronics firm LG Display, gives a rousing plenary talk here - actually a narration to a splashy LG video worthy of one of its billboard-size giant screens with 33 million sub-pixels. His address highlights a dazzling set of new products that LG believes will out-perform those of its rivals, pushing aside LCDs and the rest.

For emphasis, Yeo shows clips of the company's giant OLED videowall in Dubai Mall, featuring no fewer than 820 55-inch panels. The 14-meter-high screen is rated by the Guinness Book of Records as the largest anywhere, with the highest resolution. Switching focus from size to portability, Yeo says that "LG Wallpaper" is his favorite new product. Featuring a large (77 inch) but almost paper-thin screen, it can be fixed onto a wall with a magnetic backing, and easily moved elsewhere in the home.

Yeo notes that LG is also working toward displays for automobile windshields and side windows, while another new feature would see an OLED screen turned into an image of hi-fi speakers to provide an "immersive" sound experience that the marketing chief has dubbed CSO, for "Crystal Sound OLED."

As well as extolling the technological virtues of OLEDs, Yeo points out some lingering limitations, admitting the need for higher luminance and a wider color gamut. "We are working on material with a longer lifetime, [and] with improvement of oxide TFT mobility," he says. But the technology has come an awfully long way in just a decade, when the very first OLED TV measured just 11 inches. "What we have achieved," says Yeo, "is simply unbelievable. It was very difficult."

Sang Deog (Eddie) Yeo has been working for display industry for about 40 years. He worked for LG Electronics for 20 years mainly developing panels and TV/ monitor sets. He may be the person who has been working for LG Display for the longest. He was the CTO and head of OLED Business Unit. Now he is Chief Marketing Officer, and in 2017 held the position of president of KIDS (Korean Information Display Society).
