Narrow Pixel Pitch (NPP) LED display
Mini & micro-LED products
3 Description
With the pixel density getting higher in narrow pixel
pitch LED Display or Mini & Micro-LED products,
there are urgent demands for LED drivers to address
those critical challenges: 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, excellent display performance to serve
the growing needs of higher display quality.

The TLC6983 is a highly integrated common cathode
matrix LED display driver with 48 constant current
sources and 16 scanning FETs. A single TLC6983
is capable of driving 16 × 16 RGB LED pixels while
stacking two TLC6983s can drive 32 × 32 RGB LED
pixels. To achieve low power consumption, the device
supports separated power supplies for the red, green,
and blue LEDs by its common cathode structure.
Furthermore, the operation power of the TLC6983 is
significantly reduced by ultra-low operation voltage
range (Vcc down to 2.5 V) and ultra-low operation
current (Icc down to 3.9 mA).
