Sony announces a new 0.23" nHD+ OLED microdisplay for wearable applications

Sony announced a new 0.23" 640x400 (nHD+) OLED microdisplay aimed for wearable devices. The microdisplay features a pixel pitch of 7.8um and a 110% NTSC color gamut. Sony aims to ship this display in 2015.

Sony says that the new microdisplay, while being smaller (and with a lower resolution) compared to their current 0.5" product, it offers a higher performance. The contrast ratio has been improved from 10,000:1 to 100,000:1, the brightness enhanced from 200 to 800 cd/m2 and the power consumption has been slashed from 400 to 140 mW. The viewing angle has also been improved.

Sony managed to increase performance by changing the shapes and positions of the sub pixels using different RGB color filter. The red and green subpixels are square while the blue subpixel is a long rectangle. Using this arrangement, Sony managed to increase the aperture ratio (i.e. less space between subpixels). In addition, Sony changed the cavity design of the white OLED, which improved the emission intensity of blue to yellow colors.

This is Sony's smallest OLED microdisplay at 0.23". Sony currently ships two OLED microdisplays: the ECX331A 0.5" XGA one adopted for camera EVFs and the 0.7" ECX332A 720p one (used in HMDs).

Have these microdisplays PMOLED?

No, these are AMOLED displays

Thank you. But I like PMOLED (I have Dreambox 800HD SE (satellite) receiver with PMOLED color :) ) because it's similar to CRT due to flicker by scanning horizontally. :(

A PMOLED architecture cannot reach such a high resolution...

Ok but it's possible that PMOLED can get high resolution in future.

Thank you. ;)

Maybe. Over the past few years we've seen several companies trying to push new addressing schemes for PMOLED displays - but none were adopted commercially.


Anyone know how to buy these SONY panels and how much is the prices? (0.23", 0.5", 0.7" are good for me)

Thank you :)

Same here man, I wanna buy some too.
