Polymer Could Lead to Improved LCDs
Researchers have shown recently that an external electric field can change the alignment of the polymer MEH-PPV in liquid crystals. This alignment can polarize the light emitted by the liquid crystals in a display, which increases the brightness and contrast, possibly without the need for a second polarizer. Because MEH-PPV, or poly[2-methoxy-5-(2'-ethyl-hexyloxy)
-1,4-phenylene vinylene], fluoresces in the visible range, it can be used for color displays.
