发明名称 LED DIGIT DISPLAY DEVICE AND ITS PRODUCTION
摘要 PURPOSE:To provide the LED digit display device with which the constitution to a small size is possible, the yield is improved, the workability is good and the detection of defects during the course of an assembly stage is good. CONSTITUTION:This LED digit display device 10 is constituted of a printed circuit board 11 which has first conductive patterns and second conductive patterns disposed adjacently to the first conductive patterns in plural light emitting regions on its front surface and has pin terminals 12 implanted on the rear surface so as to be connected to the respective conductive patterns, a lamp house 13 which is insert molded of an opaque material so as to enclose the front surface of the printed circuit board 1 and at least the regions of the pin terminals 12 of the rear surface and to have emitted light take-out holes 13a for exposing the respective light emitting regions upward, LED chips 14 which are packaged on the first conductive patterns within the respective emitted light take-out holes and are connected with the associated second conductive patterns and a mask film 15 which has light transmissive parts 15a for delineation.
