Macroblock’s innovative DaVinci driver IC redefines LED display performance. Inspired by Leonardo da Vinci—an icon of scientific and artistic brilliance—this cutting-edge technology combines advanced features to tackle common challenges in professional shooting and energy efficiency.
Key Features of DaVinci Driver IC
Adaptive Refresh Rate – Eliminate black band issues when capturing high-quality video, frequent frame-rate changes can introduce unsightly black bands. DaVinci’s Adaptive Refresh Rate function smartly extends LED illumination between frames to increase refresh rates. This flexibility prevents black bands during shooting, ensuring a smooth, professional-quality image.
Low-gray Refresh (2X-32X) – Consistent performance at low brightness is limited by traditional PWM dimming at low brightness, many displays suffer from flickering and scanning line artifacts. The Low-gray Refresh function of the DaVinci driver IC delivers a high refresh rate even at reduced brightness. This eliminates flicker, whether viewed by the human eye or captured by cameras, enhancing clarity and performance.
PAM+PWM｜19-bit Grayscale – Accurate color reproduction. LED displays can exhibit color shifts at low brightness levels because the LEDs aren’t fully activated. DaVinci overcomes this challenge with its advanced 19-bit Grayscale engine. The result is high contrast, a consistent low-brightness display, and excellent color accuracy without shift.
Low Knee Voltage – Enhanced energy efficiency. Energy efficiency is critical in modern electronics. While most driver ICs reduce power consumption only when the display is off, DaVinci employs a low-knee voltage design across high and low current outputs. This approach cuts power consumption by up to 20% during operation, aligning with today’s sustainability standards.
