Another cheap LCD, doesn't currently have any use of it though.

The screen model tells me it's a 1601 character screen. So based on the chip size I could know the model number, then based on the datasheet and ITO trace I got the pintout.

Then comes the result. Seems like the screen is a TN one instead of HTN or STN, resulting in extremely poor viewing angles.
