A first board includes a first insulating substrate including a first main surface, a first electrode pad, and a first resist film. The first electrode pad is a conductor pattern provided on the first main surface. The first resist film is provided on the first main surface and is located closer to the first electrode pad than any conductor provided on the first main surface. The first resist film is spaced away from the first electrode pad with a gap provided between the first resist film and the first electrode pad. The first resist film is thicker than the first electrode pad.

The present invention provides a flexible substrate, a method of fabricating the flexible substrate and a display panel. The present invention has the advantages that the bendable region of the flexible substrate forms a curved section in the same direction as the bendable direction of the bendable region, thereby reducing the stress of the flexible substrate in the region and reducing the risk of breakage of individual layers of the flexible substrate when bent.

To provide a circuit board in which a curvature of a display surface can be controlled, or to provide a highly portable circuit board. A circuit board includes a substrate with flexibility and a curvature control mechanism. The curvature control mechanism includes a first electromagnet and a second electromagnet provided over a first surface of the substrate, an insulating film provided over the first and second electromagnets, and wirings electrically connected to the first and second electromagnets.

Methods are provided for manufacturing shape-retaining non-flat devices comprising components integrated on a device surface, the non-flat devices being made by deformation of a flat device. Based on the layout of a non-flat device, a layout of a flat device is designed. A method for designing the layout of such a flat device is provided, wherein the method includes inserting mechanical interconnections between pairs of elements to define the position of the elements on a surface of the non-flat device, thus leaving zero or less degrees of freedom for the location of the components. Based on the layout of a flat device thus obtained, the flat device is manufactured and next transformed into the shape-retaining non-flat device by means of a thermoforming process, thereby accurately and reproducibly positioning the elements at a predetermined location on a surface of the non-flat device.

Systems and methods for cold forming one or more features (106) in a flex circuit (100). The flex circuit (100) includes: an electronic circuit (102) connected to a substrate (104). When the substrate (104) is in a planar state, one or more areas deemed to be bent (or otherwise augmented) in the cold forming process, are additionally and selectively plated with an extra layer of metal (108), such as copper, so that only these one or more areas are now capable of being cold formed into shapes accurately.
