Commercial display is a display installed in public areas. With the advantage of being able to deliver various information without being restricted to a place or time, it is becoming a new display market.
In order to lead increasingly expanding commercial display market, key panel companies are leaning toward high resolution and large size panel exhibitions. Recently released commercial displays have enlarged the size by attaching small LCD panels in a tile style creating bezel between panels. In LCD sector, commercial display products with minimized bezel are being developed.
However, 8K ultra high resolution commercial display has been produced without bezel through OLED. In SID 2015, SEL revealed world’s largest 81inch 8K OLED multi display that was produced by combining 36 13.5inch 8K flexible AMOLED panels.
The key technology is transparent sections of right and bottom edges of the panel. The FPC and scan driver sections of each panel are overlapped with corners of transparent edges (see below diagram).
Daiki Nakamura of SEL revealed that commercial displays of various sizes and shapes can be produced using flexible AMOLED panel and as it is suitable for applications on columns, commercial display can be a new market for OLED.
SEL had previously exhibited 27inch 8K multi OLED display using 4 13.5 inch 8K flexible OLED panels in Display Innovation 2014.
