Method and device for eliminating bubble formation within a liquid crystal display

摘要

A device and method for maintaining the volume of a liquid contained within a cavity between two substrates to something equal or nearly equal to that of the volume of the cavity. A particular application is a liquid crystal display (LCD), in which a liquid crystal (LC) material is contained within a cavity between two flat display substrates. The device serves to minimize the volume differential between the liquid and the cavity caused by a change in temperature of the display, such that the formation of bubbles within the liquid is substantially or completely prevented. In so doing, the device essentially eliminates thermally-induced defects that would otherwise be visible to the user.
