I have an LCD display salvaged from a knockoff calculator that I had been keeping for one day I might try to reverse engineer it. This stuff is both informative and fun. Good work thanks for sharing!
A calculator will likely have a "controllerless" LCD wherein the display is just the two pieces of electrodised glass with the liquid crystal between them and polarisers on the outside, as the controller will be part of the ASIC.
yep, this is such a great and detailed writeup. I have never decapped or even freed a chip from that black epoxy blob but after reading this I feel I could do it if I needed. I have saved this for the future.
I have a old clock radio in a box which I was thinking to turn into a internet/podcast radio at some point (so I could always get the news right when I'm supposed to wake up)
I was planning to retrofit a piTFT or something into it but it would be much cooler to reuse the existing LCD... although based on the amount of work required and history of me completing these "interesting" projects I have on the shelf... I will probably do neither and at some point just buy something suitable :-)
In this case he had 150+ of them, so it wouldn't matter too much if he destroyed a few of them in the process. It would be more nerve-wracking to do this on something you don't have many of.
