The adsorption and desorption of the ions are closely related to the image sticking of liquid crystal (LC) cells. We made an effort to measure the fixed quantity of ion concentration by measuring the residual DC voltage in LC cell and the surface anchoring energy in PVA cell. To understand the mechanism of image sticking, we studied these adsorption and desorption activation energy and found that the desorption activation energy increases as the surface anchoring energy does, and this relationship is rather universal. This observation led us to a conclusion that smaller anchoring energy is required to reduce the image sticking of LC cells.
