NHD-3.12-25664UCB2 application field and working principle

NHD-3.12-25664UCB2 are display modules belonging to the general category of displays, LCD, OLED and Graphic. This module is an LCD (Liquid Crystal Display) which utilizes a reflective LCD tech- nology, or an EL backlight, to display text and graphics. As indicated by its model, NHD-3.12-25664UCB2, it has a 3.12 inch diagonal display area and an active matrix resolution of 256 x 64. It has white reflective, blue mono-chrome positive with RGB backlight, and yellow and black EL Polarizer types.

Application Fields

NHD-3.12-25664UCB2 are mainly used in industrial applications such as medical equipment, HMI\'s (Human Machine Interfaces), gas analyzers and home appliances. Due to its large display area and resolution, it is ideal for intensive screen-based applications which require good sharpness and clarity.

Working Principle

NHD-3.12-25664UCB2 works under the LCD principle of operating the liquid crystals between two transparent electrodes. This is supported by a backlight for better visibility. The display module uses a TN LCD technology, which uses a twisted nematic field effect to control the orientation of the liquid crystals. When color is used in combination with the LCD display, three colored filters are used, red, green and blue, commonly known as RGB.

The light from the LCD source pass through the electrodes and the liquid crystals, which rotate the light in accordance with the signals. The reflected light is then directed towards the viewer to show the content of the display. The backlight will intensify the backlight signal and make sure the content is visible even in more difficult lighting conditions.

Conclusion

NHD-3.12-25664UCB2 is an LCD display module which utilizes reflective LCD technology or EL backlight to display text and graphics. It is mainly used in industrial applications such as medical equipment, HMI\'s, gas analyzers and home appliances due to its large display area and resolution. Its working principle is based on the LCD principle of operating the liquid crystals between two transparent electrodes, after the backlight signal is intensified.
