MODEL OF ION SOLVATION IN LIQUID-CRYSTAL CELLS

The leading display technology, active matrix display requires very hi gh reliability. Characteristic parameters for high reliability are, fo r instance, voltage holding ratio and residual DC values. Both paramet ers show a strong deterioration if some charge carrier or contaminatio n is present in active matrix display cells, and this leads to an inac ceptable contrast value of the display. The physicochemical understand ing of such contamination causes, origin or solvation, still remain un clear. A model is presented in this paper, using a simple simulation m ethod called 'sparkle' whose results are in very good agreement with t he experimental results.
