How LCD Screen does it ?

[Mustafa Umut Sarac]

How it would be possible to address every each pixel and send them different signals without interrupt at a LCD screen or camera sensor ?
I know there are transistors but how to send information to one pixel when there are thousands of them around ?
Can anyone explain if possible with transistor theory.
And how an ic compute the complex commands n such tiny space ?
We are all using such equipment and its huge problem for me.
How many transistors do we need to make an basic calculator for example ?

Look up active and passive LCD matrix displays, and CCDs. Typically pixels are addressed in a row/column fashion, not "all at once".

Not sure what this has to do with analog photography though.

Small ones are typically a matrix. Each pixel (or element in a simple display like calculator) is connected to a column wire and a row wire, to activate a single pixel you drive the correct pair of wires. For a 6-digit 7-segment display, you would normally have 6 columns (the digits) and 7 rows (the segments) and scan through accordingly. You need to scan the whole display fast enough (100Hz+) that the eye doesn't notice the flicker.

I suggest you do some googling. There are excellent free logic-design courses online that will teach you all of this, including how all the state machines work, etc.

This is not very analogue and I suggest we stop here.
