Opixs
Design Software for Next-Generation Display Concepts
Opixs is Fluxim’s latest simulation software for display research and development. It enables users to explore various pixel designs, quantify their power consumption and colour coverage, taking into account application-relevant displayed content. By making the trade-off between efficiency and technological complexity visible, Opixs helps accelerate innovation in OLED, QLED, microLED, and other advanced display technologies.
Introduction
Displays are composed of at least three subpixels defining the reachable colour space. The coverage, size ratio, optical and electrical characteristics of these subpixels determine both power efficiency and visual performance. Opixs allows scientists and engineers to test and optimize new concepts virtually, and benchmark them against established technologies.
The software predicts power distribution, efficiency, and colour gamut for any pixel layout and pinpoints possible pathways to enhance display efficiency beyond state of the art. Advanced design aspects can be addressed further by combining with full electro-optical stack design in Setfos. Opixs provides meaningful display-level data that guide design choices and support more sustainable R&D.
Test established and novel subpixel concepts based on different technologies (RGB, RGBW, Tandem, TurboLED®, etc.)

Evaluate alternative layouts (PenTile, Diamond, S-Stripe, etc.)
Quantify efficiency gains before fabrication
For a detailed overview, we have prepared the following blog:
Why Opixs Matters
Opixs key features
Flexible subpixel layouts: lateral, vertical, or mixed arrangements
Input options: import JVL characteristics, set CIE coordinates, load real images as displayed content
Detailed outputs:
Power statistics per subpixel and subpixel combinations
Heat maps for power, voltage, current and luminance
Pixel usage and colour distribution analysis
Direct computation of best colour representation for layouts with more than three subpixels, making power saving and battery lifetime extension potentials directly quantifiable.
Example Results with Opixs
Power per Subpixel
Opixs breaks down voltage, current, and power maps for each subpixel, providing channel-specific statistics and the total power. This helps identify which colours dominate power use and where degradation risks may occur.
Influence of the Form Factor
Pixel form factors strongly affect performance. Simulations of PenTile, Diamond, and S-Stripe layouts reveal how redistributing subpixel areas shifts power load, reduces blue stress, and extends device lifetime.
RGB side-by-side vs vertically stacked
Comparisons between standard RGB and tandem RGB layouts show up to 36% power savings for the same displayed image. Such insights allow researchers to quantify the benefits of stacked pixels before fabrication.
WOLED Configurations
Opixs also models white OLED (WOLED) concepts with colour filters or stacked emitters. These simulations reveal trade-offs between efficiency and colour gamut across different subpixel combinations (RGB, RGW, GBW, RBW).
