Description

Technical Field

[0001] This utility model relates to the field of LED lamp bead technology, and in particular to a TOP type two-in-one LED lamp bead. Background Technology

[0002] With the continuous advancement of LED packaging technology, the application prospects of LED chips in the display field are becoming increasingly broad, especially in high-definition display technology, where Mini LED and Micro LED technologies are gradually emerging. Among them, Mini LED all-in-one products are particularly representative. Currently, common Mini LED all-in-one products on the market include CHIP-type and TOP-type structures. The packaging process of CHIP-type chips usually adopts full flip-chip technology, but the products produced often have quality and stability issues. In contrast, TOP-type chips use a bracket as the connection component between the internal and external circuits of the chip, and its conductivity and heat dissipation performance are better than those of CHIP-type chips. Conventional TOP-type all-in-one chips use a strip to connect a single LED cup bracket. Due to the low connection strength of the strip, a larger area of ​​strip is required for connection, resulting in a large gap between the LED cup brackets and a low material utilization rate. At the same time, conventional TOP-type all-in-one chips are only designed with the number of pins required to meet the circuit design requirements of the chip, resulting in insufficient impact resistance and affecting the overall reliability of the chip.
