Overview

The BD94130xxx-M series of matrix LED drivers combines an 8-line switch controller with 24-channel current driver - allowing control (dimming) of up to 192 zones mini-LED for backlighting with a single IC. On top of that, the mini-LEDs in each zone can be independently adjusted by using a local dimming function - contributing to larger contrast ratio, lower power consumption displays.
For example, with current mainstream 10-inch class infotainment displays that consist of approx. 600 zones, the BD94130xxx-M series enable operation with just one-fourth of the number of LED drivers compared to existing (48-zone) products - decreasing LED driver mounting area by approx. 84%. And this advantage will only increase as screens become larger and the number of zones rises inside next-generation cockpits.
