The LK204-25-E is a liquid crystal display (LCD) module that is part of the members of the display module family that covers LCD, OLED character, and numeric applications. It combines a 4 row x 20 column dot matrix LCD with a wide range of built-in functions to provide versatile and cost effective solutions.

The display module has an LCD screen which uses the twisted nematic (TN) filtering technique. This type of screen has an improved response time which allows faster switching and a wider viewing angle than STN LCDs. This OLED display has a 16-character by 2-line viewing area, and a single pin contrast adjustment to provide contrast adjustment without additional components.

In terms of industrial applications, the LK204-25-E is suitable for use in laser printers, keyboards, medical equipment, test and measurement, automotive, and many other embedded applications where quick access to visual data is required. Moreover, with its built-in 256-character ROM, this type of LCD enables users to call up readily-available symbols and text for use in applications.

The LK204-25-E also offers powerful built-in functions and features such as 8 user-defined characters via CGROM (character generator), 4 different bias and high voltage modes, power saving feature (when the display is inactive, which is ideal for portable applications), and a low EMS (electrostatic discharge) susceptibility.

In terms of working principle, the LCD module works by transmitting light to and from the corresponding polarizers which in turn, affects the voltage across the liquid crystal molecules. This voltage then changes the amount of light that passes through and creates bright or dark spots on the screen. The brightness, contrast and color of the display can be altered by altering the voltage.

The module has an internal controller and drivers which interpret commands from the host system and control the drivers to determine the display. It uses an industry-standard 4-bit or 8-bit parallel data groove, allowing it to be connected directly to a host system. Also, it can be controlled with a 5V supply.

The LK204-25-E is one of the most versatile display modules available. Thanks to its selection of built-in features and the excellent viewing angle, it offers a good choice for applications in which quick access to visual data is of paramount importance.
