A flat panel display module includes a transparent substrate, a light emitting section, a sealing cap, a flexible printed circuit board and a semiconductor device. The transparent substrate with a wiring line terminal section is formed on one of surfaces of the transparent substrate in at least one of opposing ends of the transparent substrate. The light emitting section is provided in a display region in a center section on the surface on which the wiring line terminal section of the transparent substrate is formed. The sealing cap is provided for a sealing region to cover the light emitting section such that ends of the sealing cap does not reach the ends of the transparent substrate or the wiring line terminal section of the transparent substrate. The flexible printed circuit board is connected to the wiring line terminal section and extending along the sealing cap of the transparent substrate. The semiconductor device is mounted on the flexible printed circuit board for the light emitting section.
Abstract:
An article and method for making and repairing connections between first and second circuits, such as flex circuits. The article 10 includes: a flexible dielectric substrate 12 having first and second edges 14/16, and a plurality of conductive circuit traces 18 arranged on or within the substrate, wherein each of the traces extends from proximate the first edge 14 to proximate the second edge 16. Each of the circuit traces 18 includes: a first connection feature 20 disposed proximate the first edge 14; a second connection feature 22 disposed proximate the second edge 16; and at least one third connection feature 24 disposed between the first and second edges 14/16. Each of the first, second, and third connection features 20/22/24 is a plated through hole, a plated blind via, or a mounting pad. This article 10 may be used to connect together the first and second circuits 50/60 using the first and second connection features 20/22, such as by soldering. If either of the two circuits needs to be subsequently detached (e.g., because of a component failure), the article 10 may be cut so as to present a set of third connection features 24 to which a new replacement circuit may be connected.

Abstract:
A bypass piece is formed at a forward end of a extension part. Three bypass Cu wiring patterns, which cannot be formed at a extension part, are formed at the bypass piece. The bypass piece is bent from the forward end of the extension part towards the main body so as to overlap the extension part. Connecting portions of the bypass Cu wiring patterns of the bypass piece are soldered to end portions of wiring patterns of the main body.
