Abstract
A method of creating uniform adhesive layers in a planar optical display is disclosed. The method includes providing an adhesive reservoir, providing at least two optical panels, placing spacers between the optical panels, thereby forming a stack of optical panels having at least one uniform gap between adjacent ones of the optical panels, placing the stack into a panel reservoir having a height and a width, which panel reservoir is connected to the adhesive reservoir by a fluid path, and injecting adhesive from the adhesive reservoir through the fluid path into the bottom of the panel reservoir until each uniform gap is filled. A method of producing a black cladding layer having small particulate size for use in a planar optical display is also disclosed. The method includes providing black pigment having a fine particulate size of approximately 0.05 microns, placing the particulates in solution, filtering the epoxy having the fine black particles in solution, stacking a plurality of optical panels in a fixture in the presence of the filtered epoxy, and curing the stack.
