Abstract:
1. A method for bonding one or more material layers to a display panel, each of the material layers having at least one substantially flat surface and the display panel having at least one substantially flat bonding surface, the method comprising: selecting a dispenser adapted to dispense liquid bonding material between one of said one or more material layers and the display panel, the dispenser having a tip comprising a first dispensing opening and a second dispensing opening substantially opposite the first, the dispensing openings adapted to dispense the liquid bonding material from the dispenser; selecting the liquid bonding material to dispense through the dispensing openings of the bonding material dispenser; selecting a flow rate to dispense the liquid bonding material through the dispensing openings of the dispenser; positioning a substantially flat first surface of one of said one or more material layers opposite and substantially parallel to a substantially flat bonding surface of the display panel, said surfaces separated from one another by a substantially uniform air gap; positioning the bonding material dispenser at a predetermined position within said uniform air gap, and orienting the dispenser tip such that the first dispensing opening is directed at least in part to the first surface of the material layer and the second dispensing opening is directed at least in part to the bonding surface of the display panel; further orienting the dispensing openings of the bonding material dispenser such that upon initial dispensing, the liquid bonding material will contact the first surface of the material layer and the bonding surface of the display panel substantially simultaneously; dispensing the predetermined bonding material from the dispenser through the openings at the predetermined flow rate; withdrawing the dispenser from the air gap upon completion of the liquid bonding material dispensation; and curing the dispensed liquid bonding material to bond the material layer to the display panel.
