Figure 1: Unpowered Sony Ericsson S500i LCD screen at 200x magnification In our last blog post, I wrote about some of the physics and materials science principles that go into the design and manufacture of liquid-crystal display (LCD) screens.  The eponymous liquid crystals (LCs) in such a display have to be quite small in order to create a seamless image; as I mentioned in the last entry, the subpixels (the red, green and blue elements comprising a pixel, visible in Figure 1) can be smaller than a red blood cell.  Each of these subpixels needs its own [...]
