LLC-1920 LCD Interface Board

The LLC-1920 is an ultra-low-latency LCD interface board that converts HDMI video signals to LVDS. Designed for LCD and OLED panels, including those from Tianma, AUO, BOE, Innolux, LG Display, Samsung, Sharp, and others. It also provides monitoring, and control features for the finished monitor or display system. The LLC-1920 is supported by a wide selection of panel connection cables and other accessories together with system development documentation, 3D drawings and engineering support for customization.

The feature set ensures suitability for many commercial display applications, including kiosks, industrial, medical, defense, digital signage, and corporate AV. A full summary of Digital View LCD controllers can be seen here: LCD Controller Summary.

Overview
