Abstract: A method for joining moulded parts by electromagnetic welding. A joining inductor is moved along contact surfaces of the moulded parts, generating an electromagnetic field in an induction-sensitive component of the moulded part(s) to heat a thermally activated coupling means of the moulded part(s) to above a melting temperature of the coupling means. The strength of the electromagnetic field suitable for joining is determined by previously moving a sensing inductor along the contact plane, generating a relatively weak electromagnetic field to slightly heat the thermally activated coupling means to a sensing temperature, measuring the field strength generated by the sensing inductor in the moulded part(s), determining a discrepancy between the measured field strength of the sensing inductor and the field strength suitable for joining, and adjusting the field strength suitable for joining to close the discrepancy. A device for carrying out the method.

Abstract: Techniques and architectures involving fabricating a display panel, such as an electro-wetting display panel include laminating a first support plate and a second support plate together to form a laminated display panel. The laminated display panel includes an ultra-violet (UV) light curable seal disposed between the first support plate and the second support plate proximate to edges of the laminated display panel. After conveying the laminated display panel to a UV light curing station, pressurized air, gas or fluid is applied to the laminated display panel to produce a pressure on the UV light curable seal between the first support plate and the second support plate. While applying the pressurized air, gas or fluid, the laminated display panel is exposed to UV light to cure the seal.

Abstract: An apparatus for fabricating electronic displays comprises a glass substrate that includes pixel arrays formed on the glass substrate. Individual pixels of the pixel arrays include pixel walls to retain a first fluid, such as oil. The pixel arrays may include an edge seal to retain a second fluid, such as an electrolyte solution, that overlays the pixel walls and the first fluid. The glass substrate also includes a hydrophobic strip formed on the glass substrate. A wettability between the first fluid and the hydrophobic strip is different from a wettability between the second fluid and the hydrophobic strip.
