Ok, Father, this is a quick explanation, of the most scary discipline to over trow them... ok, the screen, has pixels, the pixels run on a matrix vertical and horizontal, the frames are dynamic buffering seconds after seconds, this is all encrypting an image, a site...the pixel is a rgb (colour) and its modulated in wavelets, meaning a radio generating several layers inside the pixel, also uses an encryption algorithm (or several types) as Huffman pyramid, ....so not to be decrypted ...Father, they protect the pixels on non overlapping blocks...this is electronics components ....and this hardware, finally, has a scintillator with radioactive source, probably thorium, detecting the intrusion. Do, you now understand why am I so God damm scared?
