Display screens have a wide range of applications in daily life, such as squares, sports arenas, hotels, supermarkets, and so on. They are widely used in public places where they can be seen! How to make the lifespan and brightness of LED meet the standards that satisfy users is a meaningful question! To maintain a long lifespan and high brightness of the display screen, the problems to be solved are: power supply, LED light source, heat dissipation, and three key technologies. How to improve the lifespan and brightness of display screens?
1. Power supply
The primary requirement for power supply is high efficiency. Products with high efficiency will inevitably have high stability if their heat generation is low. Usually, there are two types of solutions available in the power supply: isolation and non isolation. Isolation has a larger volume and lower efficiency, which can cause many problems during use and installation. Therefore, the market prospects for non isolation products are not as promising. Here, we mainly discuss non isolation driving solutions.
2. LED light source
The chip is placed on the connector pin, and the thermal energy passes through the silver pin to directly bring out the tropical zone generated by the chip node. Compared with traditional in-line products and traditional patch products, the heat dissipation of the chip node is qualitatively different, and the node temperature of the chip will not accumulate, thus ensuring the good usability of the light source lamp bead, and ensuring the long life and low light attenuation of the light source lamp bead. Traditional SMT products, although able to connect positive and negative electrodes through the gold wire of the chip, also allow the heat generated by the chip to be connected to the silver pin through the gold wire. The conduction of heat and electricity is conducted by money, and the accumulation of heat for a long time will directly affect the lifespan of the display screen beads.
3. Heat dissipation
In terms of heat dissipation, we separate the heat dissipation of LED light source beads from that of the power supply, without interfering with each other, to ensure the rationality of heat dissipation. There are three ways of heat conduction: convection, conduction, and radiation. In a closed environment, convection and conduction are less likely to occur, while radiating heat out is a key consideration for the lamp beads.
