The Integrated Systems Europe (ISE) 2025 trade show, a pivotal event for the global audiovisual and systems integration industry, has spotlighted significant advancements in LED display technology. Among the key exhibitors, Macroblock introduced its latest innovation—the?DaVinci Series LED Driver ICs—designed to address longstanding challenges in visual performance, power efficiency, and adaptability across diverse applications.
The DaVinci Series represents a leap forward in LED driver IC technology, targeting critical issues such as flicker, low-gray uniformity, and power consumption. The series incorporates four core innovations:
Adaptive Refresh Technology
This feature dynamically adjusts LED light emission timing to minimize banding artifacts during high-speed camera captures, making it ideal for broadcast and virtual production environments.
Low-Gray Refresh Rate (2x–32x)
By doubling to 32x the refresh rate in low-gray scenarios, flicker is significantly reduced, enhancing stability for applications requiring high dynamic range (HDR).
Low Knee Voltage Design
Optimized voltage thresholds lower power consumption by up to 20%, while maintaining surface temperatures below 40°C. This not only improves energy efficiency but also extends LED lifespan by mitigating heat-related degradation.
Integrated PAM+PWM with 19-Bit Grayscale
Combining Pulse Amplitude Modulation (PAM) and Pulse Width Modulation (PWM), the series achieves 19-bit grayscale precision. This eliminates color shifts and ensures seamless transitions in mid-to-low gray levels, aligning closely with HDR10’s Electro-Optical Transfer Function (EOTF) for superior contrast.
Macroblock’s DaVinci Series includes multiple driver IC models, each optimized for specific use cases:
MBI5292 (32 Scans, 16 Channels)
As the flagship model, the MBI5292 integrates all DaVinci innovations, including 19-bit grayscale and low knee voltage. It targets high-end applications such as live events, virtual production (VP), and premium indoor displays. Demonstrations at ISE 2025 highlighted its ability to reduce flicker and grayscale loss, validated through smartphone slow-motion recordings.
MBS7264 (64 Scans, 16 Channels)
Designed for general LED displays, this IC addresses flicker and uniformity issues in corporate, educational, and rental settings. Its Adaptive Refresh function supports 240 FPS, accommodating multi-camera shoots and slow-motion filming.
MBI5756 (64 Scans, 16 Channels)
With enhanced power efficiency, this model is suited for close-viewing scenarios like luxury retail, museums, and classrooms. It offers GP and GFN packaging options to accelerate manufacturing timelines.
MBI5762 (32 Scans, 48 Channels)
Targeting immersive environments such as simulators and domes, this IC supports 240 FPS and a 7,680 Hz refresh rate. Its 48-channel design enables finer pitch displays (P1.2–P2.6), ideal for curved and dynamic visual installations.
MBS7752 (32 Scans, 16 Channels)
Built for outdoor and semi-outdoor applications, the MBS7752 handles high-current demands while reducing energy consumption. Its 16-bit grayscale and high refresh rate ensure crisp visuals for 3D billboards and live event displays.
A common challenge in LED displays is grayscale truncation, where inferior driver ICs compromise low-gray uniformity. Macroblock recommends a simple verification technique: using a smartphone’s high-speed shutter mode to capture display output. If flicker or banding appears, grayscale truncation may be present. This method empowers users to communicate technical requirements effectively with manufacturers, avoiding subpar visual performance.
The LED display market is increasingly driven by applications in virtual production, extended reality (XR), and energy-efficient outdoor advertising. Macroblock’s DaVinci Series responds to these trends by balancing high performance with sustainability. For instance, the MBI5292’s 20% power reduction and thermal management align with global energy efficiency initiatives, while the MBS7752 supports prolonged operation in outdoor environments.
Kinglight 1515-IC LED utilizes built-in driver IC to reduce LED display wiring and enhance transparency for look through LED displays.
At ISE 2025, Macroblock showcased its DaVinci Series alongside industry partners like UNILUMIN, RISEWELL, and CHIPSHOW, underscoring the collaborative nature of technological progress. By focusing on R&D and customer feedback, the company continues to refine solutions that address both current and emerging challenges in LED display technology.
For manufacturers and end-users seeking enhanced visual fidelity, energy efficiency, and adaptability, the DaVinci Series sets a new benchmark—proving that advanced driver ICs are pivotal to unlocking the full potential of modern LED displays.
