Working Principle

The OLED0821-OY is an organic light-emitting diode (OLED) display module. OLEDs are self-illuminating devices that generate light when electrical current is applied. They are constructed from two or three layers of organic material, typically containing a silica layer, a conductive layer and a switching layer.When a voltage is applied, electrons move from the emissive layer of the OLED, creating a current that excites the electrons to a higher energy level. These excited electrons then relax back to the ground state and give off visible light in the process. This is how OLEDs generate light without the need for a backlight.The OLED0821-OY is constructed from a 3-layer structure, which allows for a brighter display and better color accuracy. The display is powered by 4.3V and the current is controlled by the speed control pin on the module.

Conclusion

The OLED0821-OY is a monochrome passive matrix OLED display module from Winstar. It offers high-quality display output, a wide viewing angle, a high contrast ratio and long life. It is suitable for a wide range of applications, including automotive, medical and industrial. The display module is powered by 4.3V and is easy to use and configure, making it ideal for quick and efficient system integration.
