[0002] As a key component of the display screen, the performance of LED lamp beads directly affects the display effect and service life of the display screen. With the development of LED technology, the brightness and energy efficiency of LED lamp beads are constantly improving, but they still face some challenges in practical applications, especially the problem of vulcanization. Vulcanization will cause the performance of LED lamp beads to decline and shorten their service life, especially in high temperature and high humidity environments. This problem is particularly serious.

[0003] Traditional LED lamp beads usually adopt a simple packaging structure and lack effective vulcanization protection measures. This leads to the LED lamp beads to have reduced luminous efficiency and color distortion after long-term operation due to the corrosion of sulfides, and even damage to the lamp beads in severe cases. In addition, if the heat generated by the LED lamp beads during operation cannot be effectively dissipated, its performance and life will also be affected.

[0004] Based on the above situation, the utility model proposes an LED lamp bead for an anti-sulfurization display screen, which can effectively solve the above problems. Utility Model Content
