[Asia Economy Reporter Moon Chaeseok] Samsung Display announced on the 24th that it has developed the world's first large-area touch-integrated OLED (organic light-emitting diode). They explained that they have applied technology that embeds internal sensors without a touch film even for laptop OLEDs and have started full-scale mass production from this month.

Samsung Display developed the technology to embed touch sensors inside devices for the first time in the world 13 years ago. It is called OCTA. Instead of attaching a film (TSP) that recognizes human touch on the panel surface, the method creates touch sensors inside the panel. There is no need for plastic films or adhesives. There is no need to lay films that account for 6-11% of the panel. As a result, the thickness becomes thinner and the weight lighter.

Lee Hojung, Executive Director and Head of the Small and Medium Display Product Planning Team, explained, "As the display size increases, the number of touch sensors must increase, raising the level of touch-integrated technology," adding, "We developed new materials and process technologies to realize natural and smooth touch even on large areas."

Samsung Display is accelerating the restructuring of its business for laptops and tablet PCs following smartphones. With the development of large-area OCTA technology for laptops this time, the OLED business is expected to gain momentum. Panels with this technology applied are planned to be first installed in some models of Samsung Electronics' next-generation Galaxy Book series to be unveiled next month.
