As can be seen from the flow chart, the first packaging method of the conventional light-emitting diode comprises the steps of: firstly providing a plurality of packaged completed LEDs (S800); and then providing - a stripped substrate body having a positive conductive trace and a negative conductive trace (S8〇2) thereon; finally, each of the completed LEDs is sequentially disposed in the substrate On the strip substrate body, and electrically connecting the positive and the 1 extremes of each packaged light-emitting diode iriaged LED to the strip substrate, the positive and negative conductive traces of the moon bean (S804) 0 = read As shown in the second figure, it is the second type of stem of the conventional light-emitting diode: flow chart. A method of encapsulating a conventional light-emitting diode can be known from the flow chart, and the steps include: s-substrate body, if any; V tf substrate - yrj ^ foot H, negative The poles are electrically connected to the strip substrate body electrical trajectory, and then sequentially; == : strip-shaped substrate body, and each of the M339080 * positive and negative conductive traces (S902); finally, a strip The encapsulant is overlaid on the strip substrate and the LED wafers to form a light bar (S904) with a stripped light-emitting area. However, with regard to the first packaging method of the above-mentioned conventional light-emitting diode, since each packaged LED must be cut from a single LED package and then adhered to the surface. ❿ Technology (SMT) process, each packaged LED is disposed on the strip substrate body, so the process time cannot be effectively shortened, and further, when the light is emitted, the package is completed. There is a darkband between the packaged LEDs, which still has a bad effect on the user's line of sight. Further, with regard to the second packaging method of the above conventional light-emitting diode, since the completed light bar has a strip-shaped light-emitting region, the second packaging method will not cause a problem of a dark band. However, because the strip-shaped encapsulant is not uniformly excited, the light efficiency of the rod is poor (that is, the encapsulating colloid region near the LED chip generates a strong excitation light source, and is far away from the light-emitting diode. The encapsulated colloidal region of the polar body wafer produces a weaker excitation source). Please refer to the third figure, which is a schematic diagram of a conventional light-emitting diode applied to side-to-side illumination. As can be seen from the figure, when the conventional LED chip-D is applied to the lateral illumination (for example, the side light source used for the light guide plate of the notebook computer screen), the light guide plate of the notebook computer screen ^^ Non-system: 4 relationship 'The length of the base s 1 of the light-emitting diode wafer D la M339080 = relatively shortened.
