Factors that affect the quality and life of LED display

by:GKGD     2020-04-15
Customers to choose a good LED display, first, must choose good tubes, durable, adaptable. When picking screen, also want to comprehensive observation analysis, comprehensive above factors make the right judgment. Another clear own demand, investment budget and forecast the best effect, more reasonable allocation in resources, avoid unnecessary waste, loss and hidden dangers. Detailed indication of demand and future development plan of the project, ask the factory to provide the best implementation plan, project can expand function and even expand budgets, plans, in order to avoid the project is not fit for the future development needs and cause unnecessary waste of resources; Provide or demand data, installation and application environment analysis of the project to can send event prediction and prevention and solution measures are put forward, and make comprehensive assessment of the whole project plan. A renowned, focus on the LED display and IC, in fact they use of environmental conditions require more selective. At room temperature 25 ℃ or so, its working mechanism is the best. But in fact a outdoor screen will be used in different temperature environment, may be in more than 60 ℃ in summer, winter may be in - Below 20 ℃. LED display, IC work efficiency and performance, brightness is inconsistent, the screen body is natural flowers. Under the condition of different temperatures, red, green, blue three kinds of the brightness of the light attenuation and drop is different, at 25 ℃, the white balance is normal, but at 60 ℃, the three colors of the brightness of the leds are decreased, and the attenuation values are not consistent, so will produce the whole screen brightness decline and the phenomenon of partial color, the quality of the whole screen will drop. The IC? Working temperature range is in - IC 40℃— 85℃。 Due to ambient temperature is too high the casing temperature, if the temperature over 85 ℃, IC, because temperature is too high, cause of the work is not stable, or the channel between current extraction and temperature drift or caused by too much difference between flowers screen. Second, the box body design for LED display is very important also, on the one hand is its circuit protection, on the other hand is a safe, as well as dustproof and waterproof effect. But more important is whether the ventilation cooling system of hot circuit design is good, with the increase of boot time and outside temperature, the components of the thermal drift also increases, resulting in image quality becomes poor. Three, reliable power supply is also very important, because the power under the condition of different temperatures, the working stability, output voltage and load capacity will also be different, because it for the logistics function, therefore its ability to directly affect the quality of the LED display. Different LED production process, the screen assembly process, installation, technical experience, will directly affect the whole project schedule, cost, safety, performance, display effect and quality, service life and maintenance cost, must therefore advance from the manufacturer or the various understanding, compare the performance characteristics of products and projects on various aspects, plan to choose the most suitable for his needs, understand the strength of the manufacturers, the good faith, service content and quality, these are the basis of the project can be good and long-term cooperation and guarantee.
