Abstract
A tool for use in affixing an optical component, such as glass, to a liquid crystal display (LCD) using a silicone gel mixture includes, in one embodiment, a unitary metallic platen that is shaped to define a central window. A narrow shelf is defined around the central window to support the optical component during the application of the silicone gel thereon. A upwardly extending partition is formed onto the top surface of the platen around the shelf to retain the optical component fixed in place on the platen during the assembly process. A plurality of identical, spaced apart, upwardly extending standoffs are formed onto the free end of the partition to support the LCD a fixed distance away from the optical component. In this manner, the standoffs ensure that the layer of silicone gel deposited between the optical component and the LCD is uniform in thickness to optimize performance.
