The working principle of the NHD-3.12-25664UMB3 is quite simple and can be broken down into three main parts. First, the LCD module receives electrical signals from a pc, the drive, or a microcontroller. These signals can be an instruction, such as to display a certain message or picture, or an analog signal, like temperature, pressure, or voltage. The electrical signals are then converted into a pattern of liquid crystal molecules, which in turn form the image to be displayed.

The second step is the illumination of the LCD panel. The backlight turns on and the conversion of electricity to liquid crystal enables the proper colors and brightness to be displayed. The third step is the production of the image itself, through a combination of transistors, resistors, and other components. This allows for the accurate reproduction of images on the display.

In conclusion, the NHD-3.12-25664UMB3 is a highly versatile and dependable LCD module used in a variety of applications such as medical devices, industrial instruments, and point-of-sale systems. Its working principle is quite simple, involving electrical signals as input, liquid crystal as an image medium, and components such as transistors, resistors, and backlights for brightness and color reproduction.
