1 Introduction
1.1 Features
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 x16 RGB LED pixels while stacking two
TLC6983s can drive 32 x 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 2.5V)
and ultra-low operation current (Icc down to 3.9mA).
The TLC6983 implements a high speed dual-edge transmission interface to support high device count daisy-
chained and high refresh rate while minimizing electrical-magnetic interference (EMI). The device supports up to
25MHz SCLK (external) and up to 160MHz GCLK(internal). Meanwhile, the device integrates enhanced circuits
and intelligent algorithms to solve the various display challenges in Narrow Pixel Pitch(NPP) LED display
applications and Mini / Micro-LED products : Dim at the fist scan line, Upper and downside ghosting, Non-
uniformity in low gray scale, Coupling, Caterpillar caused by open or short LEDs, which make the TLC6983 a
perfect choice in such applications.
The TLC6983 also implements LED open/weak short/short detections and removals during operations and can
also report those information out to the accompanying digital processor.
1.2 Applications
The TLC6983 EVM can be used as a basic function evaluation module for the following applications:
• Narrow Pixel Pitch(NPP) LED Display
• Mini and Micro-LED Products
