NHD-0220WH-MTGH-JT#E

The NHD-0220WH-NNGH-JT#E display module is a Character and Numeric LCD (CNL) that provides the user with a two-line, four-character display for viewing data, menus or alarms. The display module uses a liquid crystal display, or LCD, technology, where liquid crystals are used to control a colored filter in order to produce an image. The glassy, transparent layer of crystals allow an electric current to pass through and, in turn, create a vivid display of characters. The NHD-0220WH-NNGH-JT#E is a backlight aligned copper conductor, where the copper is used to reduce the amount of electricity and heat being generated by the module. The conductors are covered with a transparent plastic sheet that is used to disperse and evenly spread the backlight over the LCD display.

The NHD-0220WH-NNGH-JT#E display module has a wide range of applications in a variety of industries. It is the perfect solution for automotive, medical and industrial applications such as automation displays, membrane switches and medical instrumentation. In addition, the module is also suitable for building alarm, lighting control, and home audio systems.

The NHD-0220WH-NNGH-JT#E display module is equipped with a variety of features that make it an ideal solution for most applications. The module is compatible with most controllers and has an operating temperature range of -20° to 70°C and a storage temperature range of -30° to 80°C. The module measures 66.44 mm x 65.44 mm and consists of two independent 4 character LCD rows. The characters are visible from 0.6 m and the module has a wide viewing angle of 50⁰.

The working principle of the NHD-0220WH-NNGH-JT#E display module is based on the fact that liquid crystals restrict the light emitted from the backlight in certain directions. This is done by aligning the crystals in between two transparent conductors which form a type of electrical grid. When an electrical current passes through the two conductors, the liquid crystals shift accordingly and restrict the light passing through the display, allowing only certain characters to be visible. The LCD module also utilizes a black background, which serves to further enhance the contrast of the characters.

In conclusion, the NHD-0220WH-NNGH-JT#E display module is an ideal solution for a variety of industrial and medical applications where a two-line, four character display is required. The module has a wide temperature range and a wide viewing angle, as well as a black background which ensures maximum contrast. The working principle of the display module is based on the fact that liquid crystals restrict the light emitted from the backlight in certain directions, thus allowing specific characters to be visible.
