LK202-25-FG-E is a monochrome character LCD module which is manufactured by Crystal Fontz. It is mainly categorized under Display Modules - LCD, OLED Character and Numeric. This module is designed using COB (Chip on Board) technology and is composed of a 16x2 character LCD, daughter board and a control board. With an LED backlight display and wide viewing angle, the LK202-25-FG-E has access to the HD44780 LCD controller and therefore, has been made compatible with various operating systems including Windows, Mac OS, Android and Linux.

The main application of LK202-25-FG-E is used as an information display in fields like industrial automation, medical equipment, instrumentation, POS (point of sale), telecom, printing, and educational products. The wide compatibility of the module lends an advantage when combined with various display applications, as the module will be able to fit most of the applications. Moreover, the higher immunity from the shocks, static and vibration, makes it a suitable fit for outdoor display in multi-environment applications.

Working Principle: The LK202-25-FG-E module works on the HD44780 LCD controller which helps in controlling the LCD module. The LCD\'s driver IC or a backplane is connected to the HD44780 making it compatible with 8- and 4-bit parallel groups, helping in communication between two interface ports. This also enables it to access up to 16 external lines, as the LCD can only access 8-bit data and 4-bit control commands. The LCD has various connections, including a minimum-14 connection points and a 32-byte character generator RAM (CGRAM).

The working principle is that the HD44780 LCD controller writes and read the data, while the control IC generates free flow of power and performs other operational functions. Data is written to the LCD through the daughter board, and the control board, composed of PCF8543, helps in controlling various operations such as power up, reset and other functions. The LCD module also has a 16x2 character display, with 40 characters per line, giving it a total of 80 characters. This enables users to view the data with high clarity and precision.

The module also has a wide viewing angle of up to +- 65°, and an LED backlight display. This allows better visibility and durability at the same time, and helps in fetching better data accuracy and result. Moreover, it is also programmed with various functions such as reset, scrolling, clear display and display on/off. The display is also configurable with other various display modes such as reverse video, vertical scrolling, blink, bottom view and more.

Additionally, the LK202-25-FG-E module offers users a wide range of customization options to meet their project requirements. It is also one of the most cost-effective solutions for display needs when compared to other LCD modules, as it is capable of working in temperature ranging from 0°C to +50°C, and has a high visibility from different angles.

In conclusion, the LK202-25-FG-E is an ideal choice for a range of display applications, ranging from industrial automation to medical equipment and more. It has an LED backlight display and a wide viewing angle, and is compatible with various operating systems, making it a great and cost-effective solution for various display needs.
