LED lights out of control can not be found in the regular inspection test of LED. Under severe conditions such as high temperature, low temperature, and rapid temperature changes, it is caused by the difference in thermal expansion coefficients of LED chips installation, epoxy resin, brackets, inner leads, die-bonding adhesives, PPA cups and other materials, resulting in different internal stresses. The mechanism that LEDs get out of control due to electrostatic discharge is very complicated. Equipment, tools, utensils, and the human body may carry static electricity and discharge it. This static electricity ranges from hundreds of volts to tens of thousands of volts. The discharge time is at the nanosecond level. . If the blue-green tube is out of control, it is often that the Professional LED industry-PN junction is penetrated by electrostatic discharge. Due to the complicated production process of LED display screens, electrostatic discharge cannot be prevented. Therefore, electrostatic protection must run through the entire production process.

Outdoor full-color screens are currently commonly used as direct-in-line products. Why not use surface-mount LED products? Although surface-mount LEDs are better than in-line displays, but because the surface-mounted LED display has low brightness and is waterproof, moisture-proof, The anti-ultraviolet function cannot meet the requirements of outdoor harsh environment, so outdoor full-color display is the world of in-line LED devices. Full-color surface-mount LED displays can only be used in large numbers indoors LED cabinets. The application technology of surface-mounted LEDs has not been able to meet outdoor requirements. Outdoor hot and cold environments are extremely prone to product dead lights.

Outdoor LED display steel pipe columns and foundations are generally bolted or welded. For bolted connections, check for missing bolts during inspection, and the bolts must not be deformed, slipped, loosened, etc .; if there are design drawings, the specifications and models of the bolts must meet the design requirements; the bolts should be rust-proofed. If the corrosion is serious, it must be replaced immediately, and the bolt fastening should be firm and reliable. For high-strength bolts, the embedment depth of the bolts must meet the requirements of the specification.

In short, the small pitch is “high density”. Now LED display screens are developing in the direction of small pitches. Small pitch LEDs are used to build high-resolution display screens. Small pitch displays require inputs with higher definition images and Video, which is a challenge for the processor’s load capacity. A good-performing mid-to-high-end LED video processor not only requires the processor to have higher resolution image output capabilities, higher resolution, and more video image input capabilities, but also a more number of real-time video windows In addition to the screen display capabilities, in addition to real-time display, monitoring, management and other aspects have been particular about, we can look at the following aspects.

Seamless stitching technology is a special, highly demanding projection display application that can achieve multi-screen image fusion together and reduce the stitching gap to the smallest so that it completely overlaps the stitching technology. The seamless stitching technology not only requires a complete ultra-large screen, but also has special requirements for the projection used to project an oversized picture. The biggest difference between seamless stitching technology and BSV LED power supply technology is the small gap.

The display with density above P2 generally uses 1515, 2020, and 3528 lights, and the LED Screen parts adopts J or L package. Side welding pins, the welding area will be reflective, the ink effect is poor, it is necessary to add a mask to improve the contrast. The density is further increased, and the L or J package cannot meet the application requirements. A QFN package must be used. The characteristics of this process are no lateral welding pins and no reflection in the welding area, which makes the color rendering effect very good. In addition, the all-black integrated design is LED used for compression molding, and the screen contrast has been increased by 50%.

With global energy shortage and environmental pollution, LED display screens have a wide application space due to their energy saving and environmental protection characteristics. The application of LED lighting products in the lighting field is attracting the attention of the world. Generally speaking, whether the LED lamp works stably and with good quality is very important for the heat dissipation of the lamp body itself. Currently, the high-brightness LED lamps on the market often use natural heat dissipation, which is not ideal. LED light fixtures created by LED light sources are composed of LEDs, heat dissipation structures, drivers, and lenses. Therefore, heat dissipation is also an important part. If LEDs do not dissipate heat well, their lifetime will be affected.
