Device Information

The LP5891 implements a high speed, rising-edge transmission interface to support up to 32 cascaded devices. The device supports up to 50MHz SCLK (external) and high refresh rate with maximum 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 or micro-LED products: dim at the fist scan line, upper and downside ghosting, non-uniformity in low grayscale, coupling, caterpillar caused by open or short LEDs, which make the LP5891 an excellent choice in such applications.

The LP5891 also implements LED open, weak short, short detection and removal during operations and can also report the accurate fault position information out to the accompanying digital processor.
