That's right. Take a look at this next applet; it's a model of a calculator
display. Selecting "outside" shows you the display itself; select "inside"
to see the electrodes and liquid crystal molecules underneath.
That's really cool. It looks like the "pixels" in this display are much
bigger than the ones in a computer screen--each one of those seven big
chunks in the shape of the number 8 is like one pixel, right?
Right--that's one reason most calculators are so limited in what they can
display. Elaborate graphics require smaller pixels, as well as color and
shading capabilities. And now I think we're ready to return to laptop
screens, and see how the ideas we've discussed here can be applied to
displaying such fancy graphics...
