NHD-0220CW-AR3 Application Field and Working Principle

The NHD-0220CW-AR3 is a two line by twenty character LCD display. It is both cost-effective and space saving and is designed mainly for industrial and medical applications. It is built with a column of 20 characters and two rows of LCD display with an aspect ratio of 8:2.

Product Features

This display module supports a wide range of character sizes and its small footprint makes it suitable for applications with limited space. It also supports contrast adjustment and reverse polarity. The module is designed to operate at a temperature range of -20 to +70 degrees Celsius. As a result, it is resistant to harsh industrial and medical environments.

Applications

NHD-0220CW-AR3 is generally used as medicaments information such as dosage instructions. It is widely used in industrial machines, equipment and tools. It can also be used in miniature machines, such as lab scale printers, numerical controlled machines and meter gauge simulators. It is also used in IoT and wearable device applications, especially for applications which require two rows of LCD display in a constricted space.

Working Principle

The NHD-0220CW-AR3 works by utilizing liquid crystals to display the characters. Liquid crystals are transparent crystals which respond to electric signals. It consists of two sheets of glass sealed together, between which is a layer of liquid crystals. The upper part has a transparent hard coat on the inner surface. When an electric signal is applied to the electrodes on the glass, the liquid crystal molecules rearrange themselves and align in the direction of the electric field. Depending on the voltage applied to the electrodes, these molecules will either be in an off or on state, which produces the LCD display.

Conclusion

NHD-0220CW-AR3 is a cost-effective and space saving LCD display module which is widely used for industrial, medical and IoT applications. It works by utilizing liquid crystals which respond to electric signals and rearrange themselves accordingly to produce a display. As it has a wide range of applications, it is widely used in many applications requiring two rows of LCD display in a constricted space.
