LED Display Reliability Prediction
The LED display screen is based on advanced video display technology, using ultra-bright LED electroluminescent materials as display devices, equipped with audio and video systems, and can play various graphic information and multimedia information synchronously with audio and video.
It integrates LED display technology, visual principle, computer technology, video technology, and electronic technology. It is mainly used for indoor and outdoor large-scale electronic graphic display and video image display, and is widely used in various standardized business windows (such as financial, Post and telecommunications, electric power, metallurgy, petrochemical and other industries), advertising, cultural and sports centers, and graphic display in public places (airports, stations, ports), has a very broad application prospect.
Like all products, whether LED products have high reliability will directly affect the actual use value of the product. Therefore, when designing the LED display screen, when the system’s performance indicators and cost requirements are put forward, it is hoped that the developed display screen can achieve high reliability, long service life, and better working stability. performance, ease of maintenance, and safety.
Based on these requirements, the performance and reliability of the components used in each module in the system must be analyzed before development and production, and the final stable state of the entire LED display screen must be estimated and calculated to analyze the units with high failure rates in the system , so as to take necessary corrective measures (such as applying redundant systems, replacing components, formulating regular maintenance procedures, strictly controlling manufacturing processes and strictly controlling inspections, etc.) to improve the system, reduce the failure rate, and concentrate the design energy on the weakest part of the system . In addition, reliability analysis can help designers compare various design schemes, find the design scheme that maximizes the system reliability index, and provide a basis for selecting system components, components, parts and materials, and provide a basis for design review. , failure mode, impact and hazard analysis, maintainability analysis, logistics support, thermal design, etc. to provide information.
