HL1604A 16×4 Character LCD Display Module, Parallel 16-Pin

The HL1604A 16×4 character LCD display provides four lines of text for equipment panels and instrument readouts. It features a 16-pin connection, a 4-bit or 8-bit parallel interface, and an 87 x 60 x 12.5 mm module outline.

The HL1604A is a 16×4 character LCD display module for presenting text, numbers, and status information on equipment panels. Its four lines accommodate 16 characters each, while the COB construction integrates the display electronics into a module measuring 87 x 60 x 12.5 mm.

Suitable applications include instrument readouts, equipment menus, and operator status panels. The module uses a 6800-type parallel interface supporting 4-bit or 8-bit data transfer through a 16-pin connection. Before integration, confirm the required supply voltage, optical configuration, and backlight option, and allow access to the contrast adjustment connection.
