Sony's Rollable Mini-OLED Display Wraps Around a Pencil

Sony's Rollable Mini-OLED Display

Sonny has a new Organic Field-Effect Transistors (OTFT)-driven OLED display that they are calling "rollable," as in, it's so small, you can wrap it around a pencil. The project required OTFTS that use semiconductor material that is capable of delivering eight times what a conventional OTFT can.

The company released a statement saying, "This was achieved due to the development of integration technologies of OTFTs and OLEDs on an ultra-thin 20 μm thick flexible substrate and soft organic insulators for all the insulators in the integration circuit. By combining these technologies, we successfully demonstrated the world's first OLED panel which is capable of reproducing moving images while being repeatedly rolled-up - around a cylinder with a radius of 4 mm - and stretched.

The display is 4.1 inches wide and has 432 x 240 RGB pixels. Resolution is 121 pixels per inch and it offers 16, 777, 216 different colors. Peak luminance is greater than 100 cd/m2 and contrast ratio is 1000:1. Minimum bending radius is 4 mm and panel thickness is 80. The driving scheme is 2T-1C voltage programming with OTFTs.
