Introduction

The LK202-25-R-V is an LCD 2x20 character display module, also known as a passive Matrix LCD. It is often used in industrial, medical and consumer display applications. The LK202-25-R-V has a viewing area of 51mm x 16.2mm, which is smaller than many other LCD displays. It is designed to provide a bright, easy to read display with a good range of font sizes and character styles to choose from.

Application Fields

The LK202-25-R-V is a reliable, cost-efficient choice for LCD display applications that require a small viewing area. It is often used in industrial, medical, and consumer display applications. Industrial applications such as HMI, process control and monitoring, ATMs, vending machines, and bar code readers all use the LK202-25-R-V. It is also commonly used in medical equipment, such as patient monitors and laboratory equipment, as well as consumer applications such as television and video game systems.

Working Principle

The LK202-25-R-V is a passive Matrix LCD displays. Passive matrix LCDs are constructed of two substrates, a rigid glass sheet and a flexible sheet of plastic. The two sheets are separated by a thin gap and the liquid crystals between them are manipulated by placing appropriate voltages on specially designed electrodes. These voltages cause the liquid crystals to twist and untwist, changing the optical properties of the display. This allows the LK202-25-R-V to produce a wide variety of character and numeric displays.The LK202-25-R-V has a 12X80 pixel resolution. The resolution of the display is determined by the size and shape of the electrodes, as well as the liquid crystals and materials used in the display. The electrodes are arranged in rows and columns, with each row and column containing two different electrodes. When the two electrodes corresponding to a particular row and column are activated with the same voltage, the liquid crystals between them twist, allowing light to pass through. This allows the LK202-25-R-V to display characters and numerical data with a variety of sizes and styles.

Conclusion

The LK202-25-R-V is a reliable, cost-efficient LCD display module, that offers a small viewing area and a wide range of characters, numbers and fonts. It offers reliable performance in a wide variety of applications, including industrial, medical, and consumer displays. The LK202-25-R-V is a passive Matrix LCD display, and it works by manipulating the liquid crystals between a rigid glass sheet and flexible sheet of plastic. By activating the electrodes in the display, the liquid crystals twist and untwist, allowing light to pass through and creating the characters and numerical data displayed on the screen.
