ALC-4096 LCD Controller Board

The ALC-4096 LCD controller is an interface board converting video signals from HDMI, DisplayPort, and USB-C to the signals required by compatible LCD panels, such as those from Tianma, AUO, BOE, Innolux, LG Display, Samsung, Sharp, and others. It also provides image management, monitoring, and control features for the finished monitor or display system. The ALC-4096 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.
