➡ USB-C for 4K Video, serial control, and touch
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, security, digital signage, and corporate AV. A full summary of Digital View LCD controllers can be seen here: LCD Controller Summary.

Build your own interface: RS-232 control
The ALC-4096 has an extensive RS-232 command set — backlight and brightness, input selection, image adjustment, power, panel timing, EDID, and status readback. That means the finished product does not have to use our on-screen menu: you can build your own interface, in your own branding, and drive the board from it.
The gallery below shows 21 worked examples — the same brightness function, presented twenty-one different ways. Each is a single, self-contained HTML file you can copy and make your own, and each sends a real command underneath.
Examples from the Digital View UI Controls Gallery. Open the gallery to try each one live, copy its HTML or download it. (Click the image to enlarge.)
Try one here. This is a live example control — drag it, and it behaves exactly as it would in your own interface. It is a user-interface demonstration; it is not connected to a board on this page.
The commands themselves are listed in the ALC-4096 manual, with a general guide in Downloads & Resources below.
