Yes, I'm just sure that most people have a couple of broken or old mobile phones at home. It’s a pity to throw out, let it lie, maybe it will fit. Here in the article I will offer you homemade work on this "maybe". Glowing screen with any picture you like. Simplicity, no programming or software. You can put the screen in a frame, in the computer case, on a bicycle, etc.
We need: 1. Screen (Thank you, CEP) 2. Picture (preferably printed on a sheet of A4 format). You can also color 3. Resistor (Optional)
We take the screen from the phone (I took from the Chinese nokia n95)
We open it and remove all the insides, it should turn out like this:
We take a picture (this may be a photo, logo, etc. But I took the Adidas logo)
Insert a picture.
Now you need to find the contacts for powering the LEDs (If you have a high-voltage power supply, it is advisable to connect it through a resistor so as not to burn the LEDs)
We connect to the power source and voila!
You can put the screen in a frame, in the computer case, on a bicycle, etc.
It all depends on your imagination.
