The LK202-25-GW-E manufactured by CII Hirose is a 20 x 2 character LCD module that has a light grey background and a white character color. The part number suffix "-E" indicates that the LCD module has an extended yellow to green viewing angle, perfect for applications requiring good visibility from the side.

The LK202-25-GW-E is typically used in applications that require it to be used as an information display. This could be in a range of industries such as retail, industrial, medical, and telecommunications. It could be used in situations such as bar code scanning, communicating product information, displaying menus in a restaurant, providing medical results, or alerting customers when their telecom services are down.

The LCD module also has wide temperature range capabilities, making it suitable for both indoor and outdoor applications. Built in features make it a unique addition to any environment. It has PCB mounting, positive/negative voltage polarity, and adjustable LCD contrast, making it ideal for a wide range of potential applications.

The underlying principle of the LK202-25-GW-E is the LCD display which uses liquid crystal as a material. The LCD module\'s voltage-regulated controller outputs the desired characters, symbols and graphics onto the module\'s LCD display.

The module\'s LCD display consists of two zigzag polarizer plates. These LG display polarizer plates have a smooth and parallel orientation for perfect readability. One of the polarizer plates is the “passive matrix” and the other is the “active matrix”. In between the polarizer plates, there is a layer of liquid crystal. When the matrix of conductors are energized, it creates an electrostatic field, resulting in a horizontal displacement of liquid crystal as well as a change in the birefringence angle. This affects the amplitude and polarization of the light passing through the polarizers, allowing the characters and symbols to be seen. The transmittance of the LCD display increases depending on the voltage between the two polarizor plates, resulting in readable characters, symbols, and graphics.

The LCD module is designed using an ingenious method of ensuring the twist angle of the liquid crystals change with the optimal amount at any given voltage. This optimizes the overall angle displacement of the liquid crystals to ensure a clear and readable display even at wide angle viewing expenses.

The LK202-25-GW-E LCD module has a number of key benefits from displaying sharp readable characters and symbols to a wide temperature range suitable for both indoor and outdoor use. Its light grey background and white character color provide an aesthetically pleasing display for any application.

Overall, the module is a great choice for applications such as those in retail, industrial, medical, and telecommunications settings—wherever a clear and readable display is required. It truly has the potential to provide a competitive edge for any business.
