<p>PURPOSE:To improve multi-digit light emitting diode display constructing work efficiency by a method wherein a specific, geometric relationship is estabilished between the distance separating light-emitting diodes and the distance separating through hole provided thin plates. CONSTITUTION:A substrate 1 is provided with light emitting diode mounts 2, wiring bonds 3, through holes 4, and leads 5, and each mount 2 is separated from other mounts by a distance of (a). Each thin metal plate 6 provided with a through hole 7 for light emitting diode is separated from other plates by a distance (b), and is supported by a connecting bar 8. (Here, nb=ma, where n is a natural number larger than a natural number m.) First, in installing the thin plates on the substrate 1, the mount 2 at an end of the mount lineup is aligned upon the thin plate 6 also at the same end of the plate lineup. Next, every mth mount 2 is aligned upon every nth thin plate 6. The coinciding thin plates 6 and mounts 2 are bonded together by an adhesive and then separated from the connecting bar 8. The connecting bar 8 is then moved sidewise to the next and, as described, every nth thin plate 6 is bonded. The same is repeated. After this process, the light emitting diodes are mounted and bonded tight.</p> |
