With the pixel density getting higher in narrow pixel pitch LED display or mini and micro-LED products, there are urgent demands for LED drivers to address those critical challenges. These challenges include ultra high integration to meet the strict board space limitation, ultra low power to minimize the system level power dissipation, new interface to enable high data refresh rate with low EMI impact, and excellent display performance to serve the growing needs of higher display quality.
