The LED display industry benchmark [2025 ISLE] opened grandly on March 7, and the exhibition brought together the world's toptechnology and innovative products. Nova Nebula makes its grand debut with the world's first mass-produced PWM+PAM hybrid driver IC, creating excellent display quality for MLEDs.

Infinity, the MLED full-link PWM+PAM hybrid driver high-quality solution, presents extraordinary display effects through the deep integration of control system, intelligent algorithm, full grayscale correction and PWM+PAM hybrid driver IC.

The high-performance PWM+PAM hybrid driver chip adjusts the driving current (PAM) of each LED light on the display screen in real time based on pulse width modulation (PWM) for each frame of image, releasing the ultimate potential of each light-emitting chip.

With industry-leading technological breakthroughs, it has achieved global mass production of PWM+PAM hybrid drive technology on LED driver chips for the first time. Its excellent performance has become the focus of this exhibition.

Full-link solution to create the ultimate picture quality

Infinity solution, through video source, control system, driver IC to LED, full-link technology breakthrough, achieves precise control of images and ultimate color restoration, presenting extraordinary display effects.

In the highlight area, based on the maximum PWM drive pulse width, the drive current of the corresponding LED is further increased through PAM. While maintaining stable power consumption of the entire screen, higher peak brightness output is achieved, making the picture more eye-catching and dazzling.

Based on the minimum PWM drive pulse width, PAM is used to reduce the drive current of the corresponding LED.

Real-time independent 8-bit precise current adjustment for each LED chip, truly achieving 21-bit ultra-high gray scale (theoretically up to 24-bit or more), brightness control accuracy as high as 0.001nit, and clearly expressing every detail in the dark.

PAM expands the driving pulse width of PWM, providing ample time for screen refresh. The 1-level gray scale refresh is up to 360Hz, and the high-level gray scale exceeds 15000Hz. The picture is silky smooth and stroboscopic is completely eliminated.

Using the PAM hybrid driver to improve energy efficiency, combined with the energy-saving design of the driver chip, can effectively reduce screen power consumption. Actual measurement data shows that power consumption can be further reduced by 20%, and the energy saving effect is significant.

Nova Nebula, from algorithm to computing power, from wisdom to intelligence, continues to break through the boundaries of technology and pursues the ultimate visual beauty.

Let technology grow industrial vitality. Nova Nebula is committed to providing strong support for large-scale commercial application of MLED through technological innovation and lighting up the industry.industry value and help the industry accelerate its progress.
