How Pixel works?

I have done my homework (doing research). And I still like to
understand how to activate a pixel with a different color. I know that
within a pixel, there are three phosphor dots

And millions of of Transistors are needed

http://en.wikipedia.org/wiki/Transistor

But how exactly this works? How do we control the large number of
transistors & pixels?

Also, is Pixel same as Dot?

Thanks.

===============================
To the graphics programmer, the screen is an array of pixels... each
pixel is 32 bits...8 bits of Red, Green, Blue and Alpha. So there can
be 256 shades of R G and B, for a total of 16 million colors. The
Alpha channel is extra cerdit for grad students using Silicon Graphics
and Open GL to do transparent overlays and other cool visual effects.

But I wonder how it works internally within the LCD though. So the
subpixel got activated by different level of voltage? And why it is
more costly to have lower pixel pitch? (look at the manufacture
standpoint)

Each RGB element is a Thin Film Transistor. Each RGB element must be
refreshed fast enough to not perceive flicker.
