We describe the successful construction of a 12.1" 800x600 microencapsulated electrophoretic active matrix display incorporating an a-Si thin film transistor backplane. The display exhibits a print-on-paper-like appearance (high reflectance, high contrast ratio and wide viewing angle) and grayscale at 83 DPI, and demonstrates the material's compatibility with commercial a-Si TFT LCD backplanes.

A novel technique employing shear stress sensitive microcapsules (MC) was utilized to investigate the shear stresses that were experienced by a single polymer and the components of a polymer blend during melting, in both a lab scale single screw extruder (SSE) and internal batch mixer. It was found that the MC could sense differing melting environments when process variables such as temperature and shear rate, as well as blend constituents were manipulated.
