Unclip these clips: After removing top cover (controller chips highlighted): LCD is not held down and can be removed: |

Or one can buy an "lcd projector", which is an lcd in front of a bright light with focusing optics. |

These are used in projectors. They are small but very high resolution. A movie projector uses 3 of them with a color filter and a prism to combine the image. If you only use 1, without a color filter you can project a black and white image. I have been looking into using them with a high powered UV LED for maskless lithography. Seems like you are trying to do something similar. You can add a lens if you want to reduce or scale the projected image. If you need bigger ones your best bet is to contact a manufacturer on Alibaba or Aliexpress and have them send you a few without the reflector on the back. They are quite accommodating and if you use one of their standard sizes I doubt they will charge you extra. They can also attach a connector onto the lcd instead of just having the polymer strips. I had my own problem with those while trying to use old cordless phone screens. https://www.aliexpress.com/item/32967292016.html?spm=a2g0o.detail.1000014.12.169e666dAqG9oV&gps-id=pcDetailBottomMoreOtherSeller&scm=1007.14976.157518.0&scm_id=1007.14976.157518.0&scm-url=1007.14976.157518.0&pvid=4c991e83-cb10-4d46-bde1-62d89bd99077&_t=gps-id:pcDetailBottomMoreOtherSeller,scm-url:1007.14976.157518.0,pvid:4c991e83-cb10-4d46-bde1-62d89bd99077,tpp_buckets:668%230%23131923%2318_668%23808%235881%23686_668%23888%233325%2314 |

An article just appeared on Hackaday. https://hackaday.com/2020/02/17/transparent-lcd-makes-everything-look-futuristic/ |

I recently picked up one of these clocks for my shop, it had the clear display with the LCD digits appearing on it. Ended up returning it because it was hard to read unless you had a pretty well lit background to place it against. https://www.target.com/p/digital-alarm-clock-with-usb-charger-lark-finish-capello/-/A-51539606 |
