Sony unveils ultrathin rollable OLED
Sony on Wednesday unveiled a flexible OLED (organic light-emitting diode) display so thin it can wrap around a 4mm cylinder--roughly the diameter of the average pen or pencil.
The 80 micrometers-thick OLED display (about the width of a human hair) can continuously display moving images even while being rolled up, as Sony demonstrated in a video below.
The working flexibility is possible because engineers have managed to lose the rigid driver IC chips usually used in the substrate of a screen in exchange for a gate-driver circuit with OTFTs (organic thin-film transistors), according to Sony.
The 4.1-inch display, which … Read more
