Working Principle

The working principle of the BLK202A-GW display module is very simple. The display is composed of a set of organic or inorganic electroluminescent (EL) layers. When electrical current is applied to these layers, light is emitted, forming the characters or images on the display.

The device is powered by an AC or DC voltage from an external power supply. The DC voltage is then converted by a bridge rectifier circuit and an AC voltage is then formed to drive the display. The bridge rectifier circuit consists of two capacitors and two diodes, which convert the AC voltage into a DC voltage.

Once the device is powered, the display will begin to receive data. This data is then processed by a microcontroller which converts it into signals that can be recognized by the display. These signals will then change the EL layers, thereby forming the desired characters or images.

Conclusion

The BLK202A-GW display module is an excellent choice for a wide range of applications, such as home appliances, instruments, displays and more. It features a bright, easy-to-read display with a wide viewing angle, and its low power consumption makes it highly reliable and cost-effective.

In summary, the BLK202A-GW is a reliable and user-friendly display module, which provides an easy-to-use solution for a variety of applications.
