Sony unveils 3D and color e-paper displays at this weeks SID 2011

Sony unveiled a 13.3 inch flexible color e-paper device and two glass free 3D displays. The announcement was made at the 49th SID International Symposium, Seminar & Exhibition which is the worlds largest academic conference on display technologies. The conference is being held this week in Los Angeles, CA USA.

Sony’s 13.3 inch flexible color e-paper has a thickness of 150 microns and weighs 20g and uses a plastic substrate. The e-paper display has a 13% color gamut NTSC, a reflectance of 10% and a 100,000:1 contrast ratio.

The display’s 800 x 1200 pixel array consists of red, green, blue, and white sub-pixels. The sub-pixel measures 169 microns x 169 microns and the resolution and gradation of the screen are 75ppi and 16, respectively. The e-paper display is manufactured by applying adhesive to the glass substrate and attaching a plastic substrate. Amorphous TFTs are then formed on it with a180°C or lower temperature process. The plastic substrate is then finally removed from the glass substrate.EnlargeSonys 13.3 inch flexible color e-paper.

Sony’s 3D displays come in a 10 inch and 23 inch size and can deliver a 3D image without the use of any special glasses. The method uses a backlight for 3D images positioned between an LCD panel and a backlight for normal 2D images. Switching between 2D and 3D is accomplished by lighting one of the two backlights.
