Abstract:
A method of making a light emitting display device comprising: a casing of a predetermined height having an obverse surface, two longitudinally extending side walls and two widthwise extending side walls, the obverse surface being formed with a plurality of display segments each of which is provided at an end of a light guide; a plurality of light emitting elements disposed in the casing so as to positionally correspond to the display segments; a plurality of leads each of which has a first end electrically connected to a respective light emitting element and a second end extending toward a bottom side of the casing; and a resin filled in the light guides for sealing the first ends of the leads and the light emitting elements;the method comprising the steps of: (a) bonding the light emitting elements on a leadframe including the leads and performing wire-bonding; (b) disposing the casing on a leadframe so that the display segments positionally correspond to the light emitting elements; (c) injecting a transparent resin into the casing for filling the light guides and solidifying the resin for sealing the first ends of the leads, the light emitting elements and bonding wires; and (d) separating the leads from the leadframe and bending the second end of each lead for forming a soldering surface.
