module ZephRay;

I bought these screens some while ago. The small one have integrated controller while the bigger one doesn’t. Both were sold for $1.5 each.

The integrated controller on the small one is UC1698U, which is a CSTN controller instead of a STN controller. This do cause some trouble, since every pixel in the controller map to three pixels on the screen.

Sorry for the image quality, I should have waited till morning to take the photo.

Read more if you want to see the reverse engineered pinouts and driver source code (possibly useless).

This screen was given to me from Grassmover. But I havn't played with it since then. I tried to drive it last night, and found out that the VEE is wrong (3.xV), it should be a negative voltage. Then I found the inductor was broken, so I replaced one. Now it is working correctly except for one missing line.

Present from Silicon Labs! Guess whats inside?

This screen was manufactured much earlier than the last screen, so early that it is an STN screen instead of an FSTN one. But I would say, still a good one, I just like screens.

Just a nice-looking 320×240 controller-less LCD. Got it at a very low price ($0.7 each). I am always thinking about making something around it, but it just doesn't happen.
