28121 is a type of LCD Display Modules. They are character and numeric displays that are used for various applications, and their working principle is based on the principle of liquid crystal display (LCD).

LCD has been widely used in the modern world and it is very energy efficient. LCD displays are made up of two polarizing materials between which an electric voltage is applied to cause the molecules of the liquid crystal to shift or rotate in direction, depending on the intensity of the electric charge. This shifting or rotation causes the light that passes through the liquid crystal layer to be converted, thus producing the desired image.

The 28121 LCD display module are powered by a single voltage source and are usually composed of three or four layers. The first layer contains the liquid crystals, the second layer contains the electrodes, the third layer contains the filters, and the fourth layer contains the contact materials on the outside of the module. The contacts are arranged in the shapes of characters and numbers, providing the module with its display capabilities.

The module is activated by supplying an electrical voltage to the electrodes. The voltage passes through to the liquid crystals, where the molecules are shifted in direction according to the voltage applied. This causes the light that passes through the crystals to be converted, thus producing the desired image. The images can then be displayed on the module\'s surface in the form of characters or numbers.

The 28121 LCD display modules are used in various applications. They are used in industrial and medical equipment, high-end automotive applications, washing machines and dryers, automation and instrumentation systems, hand-held devices and other consumer electronics. They can also be used in military and aerospace projects, in educational institutions, and in many other areas.

The 28121 LCD display modules have a wide variety of characteristics that make them ideal for various applications. They are space-saving and energy efficient, providing an economical and efficient solution to display needs. They are also highly reliable and long-lasting, which makes them perfect for applications that require constant and precise monitoring. The displays are also very easy to use and maintain, and can be operated with a simple voltage input.

The 28121 LCD display modules are a reliable, efficient and space-saving solution for many different applications. They are used for a wide range of applications and their working principle is based on the principle of liquid crystal display.
