3 Description
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.
