NHD-0212WH-AYYH-JT#

Introduction

The NHD-0212WH-AYYH-JT# is a Liquid Crystal Display (LCD) that is an example of a Display Module. Display modules are used to display information in either character or numeric formats. The NHD-0212WH-AYYH-JT# is classified as a Character/Numeric LCD.

Application Field

The NHD-0212WH-AYYH-JT# LCD is an ideal solution for applications that require a Character/Numeric display. Its small size and low power consumption make it particularly well-suited for applications, such as handheld devices, where space and energy efficiency are essential. It is also appropriate for more basic applications, such as industrial and automotive instrumentation, where the easy implementation and wide viewing angle make it beneficial. This display is also frequently used for applications such as medical diagnostics and telecommunication.

Working Principle

Displays such as the NHD-0212WH-AYYH-JT# are composed of two sheets of polarized glass which act like two parts of a sandwich, with front and rear surfaces that have polarizing layers. In between the two pieces of glass, there are liquid crystal molecules which are activated by an electric current. When the electric current is applied, the liquid crystal molecules will align, allowing light to pass through them. This will produce a black text display on a bright background. If the electric current is reversed, the liquid crystal molecules will go back to their “off” state and the display will be a bright text on a black background.

Conclusion

The NHD-0212WH-AYYH-JT# LCD is an example of a Character/Numeric Display Module. It is ideal for applications such as handheld devices with its small size and low power consumption, as well as industrial and automotive instrumentation due to the easy implementation and wide viewing angle. The working principle of the LCD is based on two sheets of polarized glass with liquid crystal molecules which are activated by an electric current.
