In 1931, the International Commission on Illumination (CIE) introduced the first standardized model for describing human color perception by a “standard observer”. Almost 100 years later, we are still relying on this standard in display metrology. However, new display technologies pose challenges. If measured and calibrated based on the same CIE 1931 2° Color Matching Function (CMF), various display types will show different appearance to the observer. Display manufacturers therefore start to work with different CMFs such as the CIE 2015 observer or even customer-defined CMF functions in order to achieve good color matching across different display technologies. The LumiTop devices from Instrument Systems are spectrometrically enhanced 2D colorimeters which allow to switch between different CMF functions easily and without the need to apply any hardware changes. This enables display manufacturers to compare different CMF functions and even acquire images with multiple CMFs in parallel.

Problem Statement: High Dynamic Range (HDR) technology enhances visual experiences by providing greater contrast and colour accuracy. However, enabling HDR on virtualized displays with Windows OS presents several challenges. These include compatibility issues between the host system and the virtual environment, driver support limitations, and performance overheads. Additionally, parsing Extended Display Identification Data (EDID) for static and dynamic metadata is crucial for accurate HDR implementation.

Proposed Solution:
1. Host System Requirements: Ensure the host machine supports HDR and has an HDR-capable display.
2. Graphics Driver Support: Use graphics drivers that support HDR pass-through to virtualized displays.
3. EDID Parsing and Metadata Utilization

An OLED 4K driver using a System on Module (SOM) efficiently handles high-resolution signals and precise timing for OLED panels, which require per pixel voltage control for deep blacks and high contrast (>100,000:1). The SOM integrates CPU cores (often ARM based), GPU, memory, and I/O, enabling frame rendering, color correction, refresh scheduling, and HDR support while providing high-speed interfaces such as MIPI DSI, HDMI 2.1, or DisplayPort 1.4/2.0. It manages power sequencing, temperature monitoring, and often includes FPGA logic for real time signal control. A market survey identified SOMs from Ezurio, Toradex, and Phytec as suitable, using Linux for flexibility, making them ideal for small to medium OLED display manufacturers. These compact, scalable solutions reduce development effort and are used in professional monitors, high end laptops, automotive HUDs, and premium portable displays, delivering vivid, ultra high definition imagery in a cost effective embedded form factor.

The Internet of Things (IoT) faces persistent challenges of software fragmentation, interoperability gaps, and high maintenance costs. This work introduces IoT-Verse, a modular and standardized software platform inspired by AUTOSAR principles, designed to unify IoT software development across heterogeneous devices. IoT-Verse employs a layered architecture that integrates hardware abstraction, real-time execution environments, middleware services, and AI-driven optimization. Security is embedded throughout, including post-quantum cryptography and runtime monitoring. Case studies in smart homes and industrial monitoring demonstrate significant benefits, including 43% faster development, 37% lower maintenance costs, and 58% improved cross-device interoperability. By providing a scalable, secure, and flexible foundation, IoT-Verse offers a technical roadmap to accelerate IoT innovation and overcome chronic fragmentation, positioning itself as a key enabler of next-generation IoT ecosystems.

Quantum dots (QDs) are emerging as powerful materials that supercharge the performance of display technologies across LCD, OLED, and microLED platforms. Their unique optical properties - narrow emission spectra, tunable bandgaps, and high quantum yields - enable wide color gamuts, higher brightness, and faster response time. This talk explores how QDs have evolved from simple backlight enhancement to pixel-level color conversion, and examines their potential as future emissive materials in Quantum Dot Electroluminescent (QDEL). Key industry trends, integration strategies, and technical challenges will be highlighted, showing how QDs act as a unifying force driving the next generation of advanced displays.

Klaus Burger, KARING GmbH

KARING has been involved in the complex testing of displays, focusing on R&D, QA and EOL. Applications require systems suitable for environmental simulation in the range from -40°C up to +85°C. KARING exploring various options for test systems design to ensure the greatest possible benefit for operators. For the use of cameras in conjunction with environmental simulation, KARING has developed a special temperature-controlled camera housing. For the various tasks (homogeneity measurement, pixel errors, …) the Sirkuflex picks up various camera from the tool change system and brings them to the device under test. The housing is designed that the temperature inside is maintained at room temperature via a heat exchanger throughout the entire test sequence, without air circulation inside the housing. A special heated pane is used for the beam path. The housing's temperature is controlled both during the active phase on the robot arm and during the passive phase in the tool change system.

Although TFT and OLED dot matrix dominate display applications, segmented LCDs remain important as vertical alignment (VA) technology boosted the performance. Now, it is offering several advantages: outstanding contrast ratio ensure excellent readability even in bright sunlight; printed overlays allow the use of colours without complex pixel structures; and their cost efficiency makes them an attractive choice for price-sensitive products. They require only minimal power and can be directly driven by simple microcontrollers, reducing both system complexity and energy consumption. Their robustness and long service life make them particularly suitable for applications with long product cycles or harsh environmental conditions. Typical use cases include medical devices with clear symbolic displays, professional kitchen equipment, as well as household appliances and industrial measurement instruments and personal transportation like e-scooters and e-bikes.

The presentation addresses haptic feedback technologies for automotive displays that aim to enhance the user experience through targeted tactile responses. It begins by explaining the concept of haptic feedback and its role in modern vehicle systems. This is followed by an overview of various application areas for these technologies, such as in infotainment systems or the control of core vehicle functions. The presentation then provides insight into the underlying technological approaches—such as vibration-based or pressure simulation methods—and how they operate. Furthermore, it outlines the advantages for users: haptic feedback can not only improve usability but also contribute to increased driving safety by reducing distractions and enabling more intuitive interaction. Finally, the presentation looks ahead to future developments and highlights the potential for integrating haptic technologies further into the automotive sector. Overall, these innovations could fundamentally transform the driving experience by creating a seamless and natural connection between human and machine.

Modern displays are based on liquid crystals, organic emitters, quantum dots (QDs) or microLEDs, which exhibit different color coordinates. Due to the Helmholtz–Kohlrausch (HK) effect, they appear different even when displaying the same color at the same luminance and for the same color coordinates. We study the HK effect for three LCDs, including a QD backlight and one OLED. All were calibrated to the 'maximum common color gamut' (CCG). We conducted a user study involving 20 participants and calibrated test patterns. The subjects compared the displays, e.g. in terms of perceived brightness. This confirmed the HK effect and quantified it. For example, the OLED with a luminance of 56 cd/m² was perceived similar to the TN LCD with 65 cd/m² when calibrated for perceived brightness for green at CCG. A 10% blue luminance reduction could be recognized in different tests by subjects for the OLED. Our results can be used to reduce power consumption and improve color perception.
