Abstract
A manufacturing method for a flat panel display module includes forming a display section having a transparent substrate with a wiring line terminal section adjacent at least one edge. A light emitting section is a center section, with a sealing cap covering the light emitting section. The sealing cap is dimensioned such that an edge of said sealing cap nearest the wiring line terminal section lies inside the wiring line terminal section. A flexible printed circuit board is provided with a semiconductor device mounted thereon. The flexible printed circuit board is connected to the wiring line terminal section of the transparent substrate, and a frame is fixed around the transparent substrate.
Claims16
A manufacturing method of a flat panel display module, comprising the steps of:
- (a) forming a display section, wherein said display section comprises a transparent substrate having a wiring line terminal section disposed on a first surface of said transparent substrate along at least one edge of said transparent substrate;
- a light emitting section provided in a display region in a center section on said first surface;
- a sealing cap disposed on the first surface of the transparent substrate so as to cover said light emitting section, the sealing cap being dimensioned such that an edge of said sealing cap nearest the wiring line terminal section does not reach said wiring line terminal section of said transparent substrate;
- (b) providing a flexible printed circuit board having a semiconductor device mounted on said flexible printed circuit board for said light emitting section;
- (c) connecting said flexible printed circuit board with semiconductor devices mounted thereon to said wiring line terminal section of said transparent substrate;
- and
- (d) fixing a frame around said transparent substrate.
