Research Paper — 3D OLED displays with pixels in three dimensions

A new 3D-OLED pixel concept is demonstrated in a passive-matrix OLED display where red, green and blue sub-pixels are stacked vertically and addressed independently. The prototype achieves full-colour rendering across the sRGB gamut, 180 cd/m2 overall display brightness at D65, low crosstalk, and good pixel-to-pixel uniformity.

Prototype 3D-OLED passive-matrix display rendering a multicolour spiral, demonstrating full-colour output from vertically stacked RGB sub-pixels.

Why it matters

  • Demonstrates full-colour PM-OLED operation without colour filters.

  • Shows vertically stacked RGB sub-pixels with low visible crosstalk and good uniformity.

  • Suggests a route to lower power consumption, higher apparent resolution, and future AM-OLED gains.

FAQs

What is the main novelty of this paper?
It shows a PM-OLED display in which RGB sub-pixels are stacked vertically and addressed independently, rather than arranged side by side.

What performance did the prototype reach?
The paper reports sRGB-capable 8-bit colour rendering, about 180 cd/m2 overall display brightness at D65, less than 5% brightness variation, and a contrast ratio of at least 3000.

Which Fluxim tools can be confirmed from the paper?
None of the requested tools - Paios, Setfos, Litos Lite, Litos, Laoss, or Phelos - are explicitly named in the manuscript.
