In addition, this display is widely used in the medical field such as medical instruments and laboratory equipment. With its wide temperature range, this display is also suitable for industrial, automotive and home appliances.

Features

The MOS-AL204B-YX3SE is a low power consumption and high performance device. It has a high-contrast, long-life segmented LCD, which makes it very readable under all lighting conditions. It also features an excellent brightness and color contrast ratio, good viewing angle, clear viewing and viewing quality. Additionally, this display has many features like low turn-on voltage, 1/4 duty and 1/2 bias, high contrast, long-life segmented LCD, wide viewing angle, etc. Moreover, it also has a wide temperature range from -40°C to +85°C.

Working Principle

The MOS-AL204B-YX3SE has a two-wire serial interface which makes it easy to interface with any microcontroller device. It has a 40 pin (1 x 40) connector with integrated level shifter, which simplifies the connection with the external device. This display has a simple and straightforward control interface, with the most commonly used 8-bit or 4-bit instructions. The instructions are used to set the LCD parameters, such as display control, cursor control, display character, font and backlighting. The display can be operated either in 8-bit or 4-bit instruction mode. The data is transmitted in ASCII code format.

The voltage applied to the two wire serial interface determines the current flowing through the LCD segments. When high logic level is applied, more current flows through the segments, thus resulting in brighter display. Similarly, lower logic level leads to dimmer display. The LCM is illuminated by 12V DC backlight. This voltage is further regulated by a voltage regulator.

Conclusion

The MOS-AL204B-YX3SE is a high quality and cost-effective,easy-to-mount LCD module that is suitable for various character display applications. It features an excellent long-life segmented LCD, wide temperature range and easy to use two-wire interface, making it a great choice for all kinds of applications. With its low power consumption and high performance, it can easily fulfill all kinds of requirements for character display.
