SA08-21CGKWA: Application Field and Working Principle

SA08-21CGKWA is a type of LED Character and Numeric display module which provides crystal and lattice clear viewing, fast refresh rate and low current consumption. This display module is suitable for applications in industrial, retail, and commercial display applications, such as digital products, microwave ovens and digital clocks. This article will discuss the application field and working principle of SA08-21CGKWA.

Application Field

SA08-21CGKWA can be used in different fields. It can be used in digital products such as Microwave Ovens to display time, temperature and other information. The display logic is also suitable for commercial display, including digital clocks, digital signs, and message displays. The display\'s small size, light weight, and low power consumption are ideal for smaller applications where power conservation is paramount.

SA08-21CGKWA can also be used in industrial field, in products like electronic scales, locomotives and aero planes. In addition, it finds applications in the commercial and retail field. It can be used to display product prices and discounts in supermarkets, bars and restaurants.

Working Principle

SA08-21CGKWA is a light-emitting diode (LED) display module, which employs the use of electrodes and LEDs. The module makes use of a semiconductor material like gallium arsenide (GaAs) to emit light when electricity flows through it. The LED is mounted in an LED package and is sandwiched between two electrodes. The electrodes act as a conductive path to allow electricity to pass through the LED. The flow of electricity causes electrons in the semiconductor material to be excited and release energy in the form of photons (light).

The display module also makes use of a logic circuitry to control the flow of electricity, which in turn determines the brightness of the display. The logic circuitry is responsible for converting the electrical signal into a code that is readable by the display module. Through this code, the display can present different information, characters or numbers on the screen.

SA08-21CGKWA also makes use of a back lighting system to facilitate the visibility of the display. The back lighting system consists of an array of LEDs that are used to provide lighting for the display. The module also features an Electro-Magnetic Interference (EMI) filter which acts as an additional line of protection from excessive electrical interference. It helps to reduce the amount of noise generated from the display.

Conclusion

SA08-21CGKWA is a type of LED Character and Numeric display module which has a wide range of applications in digital products, industrial, retail and commercial display. This module achieves its effects mainly through the use of light-emitting diodes, logic circuitry, and a back lighting system.
