It is part of the range of display modules available from Ultima, a UK-based manufacturer of multimedia and display systems.

Types of LCD Modules

When it comes to display modules, the most commonly used for LCD applications are character, graphic and dot-matrix modules. Character LCDs are usually used for displaying textual content and feature a variety of sizes and shapes. Graphic LCDs are used for displaying graphical images and text, while dot-matrix LCDs are designed for displaying symbols and numbers.

Features of the BLC2041-BK-USB-WB Display Module

The BLC2041-BK-USB-WB LCD module is a character display module mainly used for displaying text data strings or messages. The module is 20x4 characters (80 columns x 40 rows) and is a monochrome type display module which features a 5x10 pixel size. The module has a white LED backlight for display legibility in low lit areas. The power supply for the module is 5V DC, with a current consumption of 120mA.The module is equipped with an RS232 serial interface, allowing communication with a computer over a 5x3 male connector. This interface allows for bidirectional communication between the module and the host computer for configuring and updating the module.

Application Fields

The BLC2041-BK-USB-WB display module is ideal for a range of applications including telecommunication systems, automotive electronic control systems, medical equipment, and industrial automation equipment.
