Opixs, the New Display Simulation Software from Fluxim
Opixs is Fluxim’s latest simulation software, developed to address the increasing complexity of today’s display technologies. With Opixs, researchers and engineers can design and check new pixel architectures to find layouts that use less power and deliver better colour, before building them.
Opixs is intended for use in both academic and industrial settings, helping users:
Test new subpixel concepts
Optimize display power budgets
Understand the impact of layout changes on efficiency
Support sustainability goals by reducing unnecessary power use
Whether you are developing energy-efficient mobile displays or high-performance large panels, Opixs can support your work.

Built for Display Innovators
Opixs simulates display power and colour characteristics at the subpixel, pixel, and screen level. It supports customized subpixel concepts such as:
Standard RGB
RGBW (Red, Green, Blue, White)
OLED pixel configurations (RGBW, White + CF, Tandem RGB, QD-LED)
TurboLED and advanced custom layouts
The subpixels can be arranged both laterally and horizontally.
Each pixel layout presents unique trade-offs between luminance, colour gamut, and power. Opixs enables users to make these trade-offs visible and measurable.
Core Capabilities
At the heart of Opixs is a comprehensive physical model that calculates:
Most efficient subpixel combination
Power per subpixel and per subpixel combination
Total display power and power density
Power per emissive area
These calculations are based on user-defined parameters such as subpixel JVL characteristics, dimensions, and colour coordinates, and depend on target display content and luminance. The tool also accounts for relative subpixel areas and allows users to compare configurations under consistent conditions.

For the given layout, Opixs computes how light and power are distributed across individual subpixel types and aggregates these into meaningful performance metrics for the full display. For layouts with > 3 subpixel types, Opixs automatically computes the most economic colour representation and makes the potential power savings quantifiable.
This level of detail is particularly valuable for next-generation display types such as microLED or OLED-on-glass, where maximising emissive efficiency is essential for both performance and thermal management.
