I'm a newbie to electronics and recently found a transparent Oled and want to connect it to a raspberry pi as a screen. How do I do that? There's the link to the display specifications: https://m.alibaba.com/product/60062973863/2-4inch-transparent-OLED-screen-240/specifications.html?spm=a2706.7835515.1998800312.15.dI3DVB
There is not much to go on there.
The screen uses an 8-bit parallel interface rather than the more common SPI interface. Potentially that sounds faster but in practice I expect it will be slower, as the Pi has hardware SPI support but doesn't have hardware parallel interface support.
The driver IC is the DA8620.
I suggest you look through /boot/overlays/README to see if you can find a device tree overlay matching the above.
Failing that look through https://github.com/notro/fbtft
Well I can explain, what kind of raspberry pi do you have? If you carefully look at the board near the edge(the opposite side of the USB edge) you will see a black thing and I'd you carefully look at the labeling on the board it will say 'display' take your screen and the cable, and try to fit in the cable in that and voila it's working
