I dismounted a ceil projector clock to know how it achieves its projection. I found a very small screen (or glass, see image) backlit by a LED.
To build some projecting stuff, I would like to buy some similar components, but I cannot find any.
To me, this is a “tiny negative LCD glass” but everything that I found is either too big, or not negative, or with prebuilt backlight (what I call a screen, instead of a glass, but maybe it is not the right vocabulary):
- 42×65 White on Dark Graphic LCD from Crystalfontz
- Blue Serial SPI Small 0.96″ 128×64 Graphic COG LCD Display Module
So what is the actual name/search keyword of this component? Where can I find some to buy?
