Finally, in 2015, I bought my first oscilloscope. However, the one I bought is a broken one:
Apparently it is working, exception there are some issues with LCD’s polarizer.
After taking it apart… The screen is just… disgusting I would say
I tried to replace it with another screen I have lying around. But… I didn’t know it was broken either
Just for fun, I installed the UG32F01 featured in https://sites.psu.edu/wenting/2013/09/20/letsdrivelcd-10-ug32f01/. For sure, it worked, but hard to see:
And finally I chose a more recent 5.7″ 320×240 screen. Nothing fancy, but works great.
