Performance of LED Display Aging
One of the most obvious performances of LED Display aging is reduced brightness. As the use time increases, the luminous efficiency of LED lamp beads decreases, resulting in the brightness of the entire display screen being lower than the initial state, and the picture will appear dim. There will also be deviations in color. For example, the originally bright and pure
colors may become dim, yellow or color cast, affecting the authenticity of the visual effect. There may also be a dead light phenomenon, where some LED lamp beads are completely off, forming black spots on the screen, destroying the integrity of the display. In addition, the refresh rate of the display may be reduced, which will cause problems such as screen flickering
and smearing, which is especially obvious when displaying dynamic pictures, seriously affecting the viewing experience.
Causes of aging
From the internal factors, the material properties and quality of the LED lamp beads themselves will affect their lifespan. Long-term use, chip aging, phosphor performance degradation, etc. will cause the display screen to age. Among the external factors, ambient temperature and humidity are key. High temperature will accelerate the aging of electronic components and deteriorate the performance of LED lamp
beads such as packaging materials. High humidity environments may cause circuit short circuits, corrosion and other problems. In addition, long-term high-load operation, such as continuous high-brightness display, will accelerate the aging of the lamp beads and shorten the overall life of the display.
Measures to deal with aging
In terms of daily maintenance, keep the display clean. Use professional cleaning tools and detergents regularly to remove dust and dirt on the surface of the screen to avoid heat dissipation caused by dust accumulation. Control the temperature and humidity of the use environment, and install air conditioners, dehumidifiers and other equipment to ensure that the display is in suitable environmental conditions. For parameters such as usage time and brightness, they should be set reasonably to avoid long-term high-brightness display. The automatic brightness adjustment function can be used according to actual conditions.
Replace aging components
When obvious aging problems such as dead lights occur, the damaged LED lamp beads need to be replaced in time. When replacing, use lamp beads that match the parameters of the original display to ensure the consistency of color and brightness. At the same time, for components such as circuit boards that are severely aged, if the repair cost is too high, consider replacing the corresponding modules as a whole to ensure that the display can restore good display performance.
