Sharp exhibits 30" rollable 4K OLED prototype

11 Nov 2019 | Rasmus Larsen |

Sharp has developed a 30-inch 4K OLED prototype display that can roll up into a box. The RGB-type OLED display is the largest of its kind.

Rollable RGB OLED

Sharp will be exhibiting the prototype for the first time at the Inter BEE 2019 show in Makuhari, Japan, later this week. The 30-inch OLED screen can roll up into a box as seen in the video below. - "In collaboration with NHK, we developed a color filterless OLED using a 30-inch diagonal film substrate," Sharp said. LG Display exhibited a 65-inch rollable OLED back in January 2018 and one year later LG Electronics announced that it would start selling its as a premium OLED TV. However, the product has yet to launch in commercial form.

Sharp says that unlike LG's rollable panel, this one is using RGB (red, green, blue) OLED, making it the largest of its kind. As there are no color filters involved, Sharp's display can potentially deliver more saturated colors. However, no details were provided besides it being a 30-inch 4K display with a 60Hz refresh rate (and top emission, IGZO). The company is currently mass producing OLED displays for smartphones and it "will continue to develop more advanced technologies and open up the future of displays". At this time, Sharp has no plans to start mass production of the 30-inch display but it hopes to realize a rollable product in the future. The prototype is also evidence that LG is not alone in pursuing the concept of a rollable OLED display. - "We aim to realize a 'rollable' product that can be rolled up into a compact (2cm radius) display with a thickness of 0.5mm and stored neatly."
