LED GOB display screen refers to an LED display screen that uses GOB packaging technology. GOB, Glass On Board, is a new type of LED packaging technology. It uses a special optical thermal conductive nano-scale potting material to fill the gaps between the lamp beads on the LED display PCB board, thereby significantly enhancing the stability of the LED lamp beads.
This packaging technology is an improvement on the existing surface-mount packaging technology (SMD packaging). Although the traditional surface-mount packaging technology is mature and widely used, it is prone to problems such as dead lamps and lamp drops. This is mainly because there is a gap between the lamp beads, which makes them easy to fall off during installation and disassembly. The GOB packaging technology has been optimized for this problem and solved the problem of LED display screens being prone to dead lights or lights out.
In addition, LED GOB display has many advantages, including waterproof, moisture-proof, dust-proof, anti-collision and other characteristics. Its impact resistance is more than 10 times that of SMD packaging, its pressure resistance is stronger, and its surface protection level is higher. In coastal and hot and humid areas, GOB-encapsulated LED displays can resist the corrosion of electronic components by chlorine ions and have good anti-salt spray effects. At the same time, it can also prevent oxidation, strengthen the connection between the lamp bead pins and the PCB, and enhance the service life of the LED module.
Therefore, LED GOB displays have excellent performance in various application scenarios such as exhibition halls, shopping malls, building curtain walls, TV stations, stages, and transportation guides, providing efficient and stable visual display solutions for various needs of modern society.
