Sony has exhibited a rollable OLED display on the SID 2010 fair in Washington. The flexible OLED is just 0.08 millimeters thin and measures 4.1 inches in size. 

Rollable OLED panel
Sony is one of the companies that believe in the OLED technology and on the technology fair SID 2010 in Washington Sony has revealed some of their new technologies.


Sony Rollable OLED

One of the new technologies is a 4.1-inch rollable OLED panel that can be rolled around a pencil. The OLED panel is just 0.08 millimeters thick (80 um). A typical human hair is 100 um (micrometers) thick.

The panel is also very flexible. It has a 432x240 pixel resolution and 16.7 million colors and a contrast ratio of 1000:1. The OLED panel builds on a so called OTFT-driven OLED display.

Sony expects to continue developing very thin and flexible OLED solutions for mobile solutions. The OLED panels offers very thin profiles and are very low-weight and durable. The flexible panel also gives manufacturers the possibility to experiment with form-factor and shapes.

Specifications
Size of a panel : 4.1 inch wide
Pixels : 432 x 240 x RGB pixels
Size of a pixel : 210um x 210um
Resolution : 121 ppi (pixels per inch)
Number of colors : 16,777,216
Peak luminance : >100 cd/m2
Contrast ratio : >1000:1
Minimum bending radius : 4 mm
Thickness of a panel : 80 um

The prototype has four times higher resolution than previous OLED panels from NHK. The resolution is 320x240 pixels and the panel is 5 inches large. It's not as flexible as the Sony OLED display, though.
