Overview

The LUX1-16K™ chip is a display driver IC designed for passive microLED arrays with up to 128 rows and 128 columns for a total pixel count up to 16,384. It supports microLED arrays with common cathode configuration using rolling-line operation. The chip has an array of unit pixel drivers, with in-pixel digital memory, 7-bit current-mode digital-to-analog Converters (i-DACs), and high-voltage drive stage. The chip is operated using a 4-wire serial programming interface (SPI), using soft commands for all the critical timing operations in the chip, allowing flexible operation of the chip. The LUX1-16K chip has been fabricated using a high voltage CMOS process, with high (11 V), mid (5 V), and low (1.8 V) voltage devices. It measures 2.4 mm x 2.7 mm, and uses chip-scale packaging with Cu bumps.
