Make an OLED Transparent Display with Infinite Creativity

In science fiction films, we often encounter transparent screens. A few years ago, Samsung introduced the world's first transparent OLED display, resembling a crystal-clear piece of art that captivated everyone with its stunning effects. However, transparent OLED panels come with a hefty price tag, limiting their adoption among users. Now, I have acquired this small OLED transparent display, and I am determined to transform it into a simple project to showcase what I envision.

This OLED transparent display has a compact size of 1.51 inches. 128×64 blue OLED pixels are evenly distributed on the screen, which allows you to view the content on the display at any angle. Also, it is equipped with a small converter that offers GDI and SPI interface. It leaves enough room for project creators to use and play.



This is a pixel dot. It is also an independent light-emitting diode. As OLEDs increase orderly, they"ll cover the whole screen. A pixel dot does not emit light when powered off, so we can sequentially control the pixel dots to light on and off to display any content on the screen.


Next, how to make the screen transparent? There are two problems. First, the light behind the screen should be allowed to pass through it. Second, the displayed content should be seen from both sides. To get that, we space the closely arranged pixel dots a bit to leave some gaps so that the light can pass through the screen from them. But now we still can't see the displayed content from the back side. That's because the light from OLED is blocked by the non-transparent PCB and metallic cathode.


To deal with that, ITO, a conductive material with 90% transparency, is used to replace the non-transparent cathode (also used for the anode) during manufacturing. And other light-tight components such as the PCBs used in general OLED displays are also placed elsewhere. 




STEP1: Connect the OLED transparent display.

STEP2: Load the sample codes in the IDE. 

DFRobot provides the relevant display library and you can find most of the basic display routines there. 



STEP3: Done! This advanced technology seamlessly combines information presentation and aesthetic design to deliver clear, crisp images through the screen, whether you're working on data visualization, creative presentation or other innovative applications.




The birth of the miracle of transparency has not only injected new vitality into the field of science and technology, but also allowed us to feel the future experience of science fiction movies in our daily lives. With a simple assembly step, we have successfully introduced this advanced technology into our projects, providing a wide range of innovative applications.
