Application Field and Working principle of OLED0821-OY-V

OLED0821-OY-V is a kind of LCD (Liquid Crystal Display) module produced by using OLED technology, which can be used for a wide range of applications, from industrial to consumer devices or even wearable. It integrates a 20 x 2 character display and provides features such as 8 x 8 dot-matrix font, small size, low consumption, low voltage, and low temperature operations. Thus, OLED0821-OY-V is the ideal choice for applications involving limited space for LCDs.

How does OLED0821-OY-V works

The working principle of OLED0821-OY-V is based on the electro-optical effect of liquid crystal molecules. Under normal operating conditions, the liquid crystal material is electrically non-conductive and cannot emit light. When an electric field is applied to the liquid crystal layer between the transmitting and reflecting polarization layers, a distortion of the electric field occurs, resulting in refraction of the incident light, which is then reflected off the reflecting polarization layer, producing a visible image.OLED0821-OY-V typically operates at a voltage between 5V to 7V and a power consumption of between 3W to 5W. The display data is stored and refreshed from a dedicated memory chip and it offers a wide range of features, such as blink and auto-scroll display functions. The module also interfaces with a controller IC via an 8B8C (RS232) serial port.

Application Field

OLED0821-OY-V is a suitable display solution for applications involving limited space, such as smart watches and other wearable devices. It is also an excellent choice for devices needing a small, efficient and low-power consuming display. In addition, OLED0821-OY-V can also be used in industrial control applications. It employs a standard 8B8C serial interface, which is suitable for many communication protocols, such as I2C, SPI and CAN. This makes it compatible with many microcontrollers and other controllers, allowing for easy integration into systems.

Conclusion

The OLED0821-OY-V is a reliable and small-size LCD module designed for limited space applications. It offers a range of features and a low power consumption, making it suitable for many types of applications. The module is compatible with many microcontrollers and communication protocols, and interfaces with a controller IC via an 8B8C (RS232) serial port. With its small size and wide range of features, the OLED0821-OY-V is an ideal choice for many applications.
