30" Flexible OLED Display (reference exhibit)
Rollable products that can be rolled up and stored neatly
We have joined forces with NHK to produce a 30V type 4K flexible organic EL (OLED) display.
The new OLED display has light-emitting elements in each of the RGB (red, green, and blue) shades (RGB light emission) on a flexible 30-inch (76 cm or so) diagonal film substrate, making it the largest display of its kind in the world*1.
Painstaking forming of the light-emitting element for each color via the vapor deposition method helps this model eliminate the need for color filters and utilize light more efficiently than ever before. Moreover, the use of a film substrate allows the 0.5mm-thin panel display unit to be rolled up compactly (radius: approx. 2cm) and stored neatly in the lower case. IGZO*2 is used as a thin-film transistor to drive the OLED elements, while NHK’s proprietary signal-processing and panel-drive technologies are used to boost screen brightness and video clarity.
In June 2018, mass production of Japan’s first flexible organic EL display for smartphones got underway. We will continue to develop more advanced technologies and open up the future of displays.
30-inch high-definition 4K OLED display
An RGB light-emitting system without a color filter, utilizing light efficiently and consuming minimal power.
Slim, lightweight and rollable (R=2cm) for excellent portability.
1 As a display equipped with an organic EL element emitting RGB (red, green, blue) colors (RGB emission method) on a film substrate without using color filters (as of November 8, 2019, Sharp survey).
2 An oxide semiconductor comprising In (indium), Ga (gallium), Zn (zinc) and O (oxygen). Used as a semiconductor material for thin-film transistors (TFT), which are used to drive organic electroluminescence and liquid crystal displays.
