Macroblock makes its debut at SID Display Week this year.

Application Highlights

Drone Remote Controller Screen

Macroblock’s backlight driver IC, MBI6334, provides the core display technology for a drone remote controller developed by a leading global brand. The mini‑LED display delivers flagship‑level image performance, featuring up to 2,000 nits of peak brightness, a million‑to‑one contrast ratio, and 98% DCI‑P3 color gamut coverage. These capabilities ensure clear visibility even under strong ambient light, enabling users to monitor shooting results with greater accuracy.

At the heart of this performance is the MBI6334, a 64‑channel constant current LED driver IC that supports an 8‑scan design and 12‑bit grayscale. A single chip can control up to 512 local dimming zones. Equipped with S‑PWM technology, it effectively suppresses flicker, while Black Frame Insertion helps reduce motion blur, significantly enhancing display quality and the overall user experience.

Floating Central Control Display

The floating central control display of the ZEEKR 7X, a premium electric vehicle model from Geely Group’s ZEEKR brand, adopts Macroblock’s MBI6353Q. This display offers up to 1,232 local dimming zones. It delivers refined image detail, vivid color saturation, high brightness, and high contrast, greatly enhancing the in-cabin driving experience.

The MBI6353Q serves as the key enabler of this central control screen. Featuring 48 channels, a 4‑scan design, and the ability to control up to 192 local dimming zones per chip, it also supports hybrid dimming and high current output. These capabilities ensure stable, clear image performance under both bright and low‑light conditions, meeting the stringent requirements of automotive display applications.

Interactive Light Panel

Macroblock’s MBI5353Q and MBI5989Q power next‑generation interactive light panels. This panel integrates tens of thousands of LED pixels with precise 32‑level grayscale control, and incorporates Liaowang’s “Micro Display Lighting” technology along with customizable smart scenarios. Through high‑resolution monochrome display performance, the panel delivers critical driving information clearly and in real time, enabling new possibilities for human–vehicle interaction.

The MBI5353Q plays a key role in enabling this interactive light panel. It is a 48‑channel constant current LED driver IC supporting 32 scan and 16‑bit grayscale, and features built‑in “Dynamic Power Saving” to effectively reduce overheating risks. This ensures stable and reliable long‑term operation while meeting automotive‑grade requirements. Working together with the MBI5353Q, the MBI5989Q is a 16‑channel PMOS IC equipped with Upper Ghosting Effect Elimination, High Contrast Interference Elimination, and LED Short “Caterpillar” Elimination. Together, these two ICs deliver an interactive light panel solution that seamlessly combines safety and modern design.

Innovative Solutions

Automotive Door Trim Concept

The automotive door trim concept incorporates the latest technology from Macroblock’s partner Hirossawa, combining traditional craftsmanship with modern technology. Inspired by classical Chinese poetry, the design offers a refined interpretation of the understated, minimalist aesthetics emphasized by the “Shy Tech” concept. This concept adopts Macroblock’s MBI6034Q, which features 12 channels, high‑current output, and long data transfer capabilities. These features enable ambient lighting to pass smoothly through a wide range of materials—including fabric, leather, wood, and plastic, meeting the design requirements of Shy Tech applications.

Invisible Mini-LED Display

The invisible Mini‑LED display showcased at the booth is powered by Macroblock’s MBI5780Q. Designed for smart cockpit applications, the display significantly enhances the immersive in-cabin experience by creating a dynamic interplay of light and shadow through the integration of technology and aesthetics. The MBI5780Q is a highly integrated driver IC featuring 48 channels, 90‑scan design, and 16‑bit grayscale. It is Macroblock’s first common‑cathode LED driver IC designed for micro‑LED display applications. The common‑cathode architecture effectively reduces overall power consumption.
